Commit a0f97e06a4 ("kbuild: enable 'make CFLAGS=...' to add
additional options to CC") renamed CFLAGS to KBUILD_CFLAGS.
Commit 222d394d30 ("kbuild: enable 'make AFLAGS=...' to add
additional options to AS") renamed AFLAGS to KBUILD_AFLAGS.
Commit 06c5040cdb ("kbuild: enable 'make CPPFLAGS=...' to add
additional options to CPP") renamed CPPFLAGS to KBUILD_CPPFLAGS.
For some reason, LDFLAGS was not renamed.
Using a well-known variable like LDFLAGS may result in accidental
override of the variable.
Kbuild generally uses KBUILD_ prefixed variables for the internally
appended options, so here is one more conversion to sanitize the
naming convention.
I did not touch Makefiles under tools/ since the tools build system
is a different world.

Change-Id: I2e83a05c5f119a7467a4d6984045d45d0c06b764
[ Upstream commit 1efdd4bd254311498123a15fa0acd565f454da97 ]
Some platforms execute their timer handler with the interrupt priority
level set below 6. That means the handler could be interrupted by another
driver and this could lead to re-entry of the timer core.
Avoid this by use of local_irq_save/restore for timer interrupt dispatch.
This provides mutual exclusion around the timer interrupt flag access
which is needed later in this series for the clocksource conversion.

[ Upstream commit 0ca7ce7db771580433bf24454f7a1542bd326078 ]
This resolves some bugs that affect VIA timer counter accesses.
Avoid lost interrupts caused by reading the counter low byte register.
Make allowance for the fact that the counter will be decremented to
0xFFFF before being reloaded.

[ Upstream commit 173a3efd3edb2ef6ef07471397c5f542a360e9c1 ]
Looking at functions with large stack frames across all architectures
led me discovering that BUG() suffers from the same problem as
fortify_panic(), which I've added a workaround for already.
In short, variables that go out of scope by calling a noreturn function
or __builtin_unreachable() keep using stack space in functions
afterwards.
A workaround that was identified is to insert an empty assembler
statement just before calling the function that doesn't return. I'm
adding a macro "barrier_before_unreachable()" to document this, and
insert calls to that in all instances of BUG() that currently suffer
from this problem.
The files that saw the largest change from this had these frame sizes
before, and much less with my patch:
fs/ext4/inode.c:82:1: warning: the frame size of 1672 bytes is larger than 800 bytes [-Wframe-larger-than=]
fs/ext4/namei.c:434:1: warning: the frame size of 904 bytes is larger than 800 bytes [-Wframe-larger-than=]
fs/ext4/super.c:2279:1: warning: the frame size of 1160 bytes is larger than 800 bytes [-Wframe-larger-than=]
fs/ext4/xattr.c:146:1: warning: the frame size of 1168 bytes is larger than 800 bytes [-Wframe-larger-than=]
fs/f2fs/inode.c:152:1: warning: the frame size of 1424 bytes is larger than 800 bytes [-Wframe-larger-than=]
net/netfilter/ipvs/ip_vs_core.c:1195:1: warning: the frame size of 1068 bytes is larger than 800 bytes [-Wframe-larger-than=]
net/netfilter/ipvs/ip_vs_core.c:395:1: warning: the frame size of 1084 bytes is larger than 800 bytes [-Wframe-larger-than=]
net/netfilter/ipvs/ip_vs_ftp.c:298:1: warning: the frame size of 928 bytes is larger than 800 bytes [-Wframe-larger-than=]
net/netfilter/ipvs/ip_vs_ftp.c:418:1: warning: the frame size of 908 bytes is larger than 800 bytes [-Wframe-larger-than=]
net/netfilter/ipvs/ip_vs_lblcr.c:718:1: warning: the frame size of 960 bytes is larger than 800 bytes [-Wframe-larger-than=]
drivers/net/xen-netback/netback.c:1500:1: warning: the frame size of 1088 bytes is larger than 800 bytes [-Wframe-larger-than=]
In case of ARC and CRIS, it turns out that the BUG() implementation
actually does return (or at least the compiler thinks it does),
resulting in lots of warnings about uninitialized variable use and
leaving noreturn functions, such as:
block/cfq-iosched.c: In function 'cfq_async_queue_prio':
block/cfq-iosched.c:3804:1: error: control reaches end of non-void function [-Werror=return-type]
include/linux/dmaengine.h: In function 'dma_maxpq':
include/linux/dmaengine.h:1123:1: error: control reaches end of non-void function [-Werror=return-type]
This makes them call __builtin_trap() instead, which should normally
dump the stack and kill the current process, like some of the other
architectures already do.
I tried adding barrier_before_unreachable() to panic() and
fortify_panic() as well, but that had very little effect, so I'm not
submitting that patch.
Vineet said:
: For ARC, it is double win.
:
: 1. Fixes 3 -Wreturn-type warnings
:
: | ../net/core/ethtool.c:311:1: warning: control reaches end of non-void function
: [-Wreturn-type]
: | ../kernel/sched/core.c:3246:1: warning: control reaches end of non-void function

: 2. bloat-o-meter reports code size improvements as gcc elides the
: generated code for stack return.

commit 28713169d879b67be2ef2f84dcf54905de238294 upstream.
This patch fixes a build failure when using GCC 8.1:
/usr/bin/ld: block/partitions/ldm.o: in function `ldm_parse_tocblock':
block/partitions/ldm.c:153: undefined reference to `strcmp'
This is caused by a new optimization which effectively replaces a
strncmp() call with a strcmp() call. This affects a number of strncmp()
call sites in the kernel.
The entire class of optimizations is avoided with -fno-builtin, which
gets enabled by -ffreestanding. This may avoid possible future build
failures in case new optimizations appear in future compilers.
I haven't done any performance measurements with this patch but I did
count the function calls in a defconfig build. For example, there are now
23 more sprintf() calls and 39 fewer strcpy() calls. The effect on the
other libc functions is smaller.
If this harms performance we can tackle that regression by optimizing
the call sites, ideally using semantic patches. That way, clang and ICC
builds might benfit too.

Fix by calling pgtable_page_dtor() in our __pte_free_tlb() code path,
so that the PG_table flag is cleared before we free the pte page.
Note that I had to change the type of pte_free() to be static from
extern. Otherwise you get a lot of warnings like this:
./arch/m68k/include/asm/mcf_pgalloc.h:80:2: warning: ‘pgtable_page_dtor’ is static but used in inline function ‘pte_free’ which is not static
pgtable_page_dtor(page);
^
And making it static is consistent with our use of this in the other
m68k pgalloc definitions of pte_free().

commit 3f90f9ef2dda316d64e420d5d51ba369587ccc55 upstream.
If 020/030 support is enabled, get_io_area() leaves an IO_SIZE gap
between mappings which is added to the vm_struct representing the
mapping. __ioremap() uses the actual requested size (after alignment),
while __iounmap() is passed the size from the vm_struct.
On 020/030, early termination descriptors are used to set up mappings of
extent 'size', which are validated on unmapping. The unmapped gap of
size IO_SIZE defeats the sanity check of the pmd tables, causing
__iounmap() to loop forever on 030.
On 040/060, unmapping of page table entries does not check for a valid
mapping, so the umapping loop always completes there.
Adjust size to be unmapped by the gap that had been added in the
vm_struct prior.
This fixes the hang in atari_platform_init() reported a long time ago,
and a similar one reported by Finn recently (addressed by removing
ioremap() use from the SWIM driver.
Tested on my Falcon in 030 mode - untested but should work the same on
040/060 (the extra page tables cleared there would never have been set
up anyway).

[ Upstream commit 969de0988b77e5a57aac2f7270191a3c50540c52 ]
Commit be7635e728 ("arch, ftrace: for KASAN put hard/soft IRQ entries
into separate sections") added a new linker section, SOFTIRQENTRY_TEXT,
to the linker scripts for most architectures. It didn't add it to any of
the linker scripts for the m68k architecture. This was not really a problem
because it is only defined if either of CONFIG_FUNCTION_GRAPH_TRACER or
CONFIG_KASAN are enabled - which can never be true for m68k.
However commit 229a71860547 ("irq: Make the irqentry text section
unconditional") means that SOFTIRQENTRY_TEXT is now always defined. So on
m68k we now end up with a separate ELF section for .softirqentry.text
instead of it being part of the .text section. On some m68k targets in some
configurations this can also cause a fatal link error:
LD vmlinux
/usr/local/bin/../m68k-uclinux/bin/ld.real: section .softirqentry.text loaded at [0000000010de10c0,0000000010de12dd] overlaps section .rodata loaded at [0000000010de10c0,0000000010e0fd67]
To fix add in the missing SOFTIRQENTRY_TEXT section into the m68k linker
scripts. I noticed that m68k is also missing the IRQENTRY_TEXT section,
so this patch also adds an entry for that too.

The m68k pg_data_table is a fix size array defined in arch/m68k/mm/init.c.
Index numbers within it are defined based on memory size. But for Coldfire
these don't take into account a non-zero physical RAM base address, and this
causes us to access past the end of this array at system start time.
Change the node shift calculation so that we keep the index inside its range.

When doing an nmi backtrace of many cores, most of which are idle, the
output is a little overwhelming and very uninformative. Suppress
messages for cpus that are idling when they are interrupted and just
emit one line, "NMI backtrace for N skipped: idling at pc 0xNNN".
We do this by grouping all the cpuidle code together into a new
.cpuidle.text section, and then checking the address of the interrupted
PC to see if it lies within that section.
This commit suitably tags x86 and tile idle routines, and only adds in
the minimal framework for other architectures.

CONFIG_FPU. Be consistent and surround the hardware FPU instruction
setup in setup_mm.c with CONFIG_FPU as well as the check for
CONFIG_M68KFPU_EMU_ONLY.
The existing classic m68k architectures all define CONFIG_FPU, so they
see no change from this. But on ColdFire where we do not support the
emulated FP code we can now compile without CONFIG_FPU being set as well.

Our local m68k architecture dump_fpu() is conditionally compiled in on
CONFIG_FPU. That is OK for all existing MMU enabled CPU types, but won't
handle the case for some ColdFire SoC CPU parts that we want to support
that have no FPU hardware.
dump_fpu() is expected to be present by the ELF loader, so we must always
have it available and exported.
Remove the conditional and reorganize the dump_fpu hard FPU code path
to let the compiler remove code when not needed.

The ACR registers of the ColdFire define at a macro level what regions
of the addresses space should have caching or other attribute types applied.
Currently for the MMU enabled setups we map the interal IO peripheral addres
space as uncachable based on the define for the MBAR address (CONFIG_MBAR).
Not all ColdFire SoC use a programmable MBAR register address. Some parts
have fixed addressing for their internal peripheral registers.
Generalize the way we get the internal peripheral base address so all types
can be accomodated in the ACR definitions. Each ColdFire SoC type now sets
its IO memory base and size definitions (which may be based on MBAR) which
are then used in the ACR definitions.

Move the selection of CONFIG_FPU to each CPU type configuration.
Currently for m68k we have a global set of CONFIG_FPU based on if CONFIG_MMU
is enabled or not. There is at least one CPU family we support (m5441x)
that has an MMU but has no FPU hardware. So we need to be able to have
CONFIG_MMU set and CONFIG_FPU not set.
Whether we build for a CPU with MMU enabled or not doesn't change the
fact that it has FPU hardware support. Our current non-MMU builds have
never had CONIG_FPU enabled - and in fact the kernel will not compile
with that set and CONFIG_MMU not set at the moment. It is easy enough
to fix this - but it would involve a structure change to sigcontext.h,
and that is a user space exported header (so ABI change).
This change makes no configuration visible changes, and all configs
end up with the same configuration settings as before.

The early setup code for the ColdFire 53xx platform accesses variables
before the RAM and other system initialization steps may have taken place.
Currently it has 2 global variables that will end up in the bss section
that are accessed during this early setup. There is a special static RAM
stack setup at this time, but not necessarily the RAM where kernel data
sections will end up.
Even on system setups where RAM is setup by a boot loader the access
to the early setup variables is before the BSS section has been initialized.
This can potentially corrupt a ram loaded root filesystem that sits in that
memory area before it has been moved.
These 2 variables are not used at all after being set, and can just be
removed.

address of the process data segment when processing application signals.
For flat format applications compiled with full absolute relocation this
effectively corrupts the a5 register on signal processing - and this very
quickly leads to process crash and often takes out the whole system with
a panic as well.
This has no effect on flat format applications compiled with the more
common PIC methods (such as -msep-data). These format applications reserve
a5 for the pointer to the data segment anyway - so it doesn't change it.
A long time ago the a5 register was used in the code packed into the user
stack to enable signal return processing. And so it had to be restored on
end of signal cleanup processing back to the original a5 user value. This
was historically done by saving away a5 in the sigcontext structure. At
some point (a long time back it seems) the a5 restore process was changed
and it was hard coded to put the user data segment address directly into a5.
Which is ok for the common PIC compiled application case, but breaks the
full relocation application code.
We no longer use this type of signal handling mechanism and so we don't
need to do anything special to save and restore a5 at all now. So remove the
code that hard codes a5 to the address of the user data segment.

"This series is all about Nicolas flat format support for MMU systems.
Traditional m68k no-MMU flat format binaries can now be run on m68k
MMU enabled systems too. The series includes some nice cleanups of
the binfmt_flat code and converts it to using proper user space
accessor functions.
With all this in place you can boot and run a complete no-MMU flat

The dma-mapping core and the implementations do not change the DMA
attributes passed by pointer. Thus the pointer can point to const data.
However the attributes do not have to be a bitfield. Instead unsigned
long will do fine:
1. This is just simpler. Both in terms of reading the code and setting
attributes. Instead of initializing local attributes on the stack
and passing pointer to it to dma_set_attr(), just set the bits.
2. It brings safeness and checking for const correctness because the
attributes are passed by value.

across all SMP architectures (Peter Zijlstra)
- add atomic_fetch_{inc/dec}() as well, using the generic primitives
(Davidlohr Bueso)
- optimize various aspects of rwsems (Jason Low, Davidlohr Bueso,
Waiman Long)
- optimize smp_cond_load_acquire() on arm64 and implement LSE based
atomic{,64}_fetch_{add,sub,and,andnot,or,xor}{,_relaxed,_acquire,_release}()
on arm64 (Will Deacon)
- introduce smp_acquire__after_ctrl_dep() and fix various barrier
mis-uses and bugs (Peter Zijlstra)
- after discovering ancient spin_unlock_wait() barrier bugs in its
implementation and usage, strengthen its semantics and update/fix
usage sites (Peter Zijlstra)
