Commit 8dc7a9c84 ("blackfin: Add export.h to files using
EXPORT_SYMBOL/THIS_MODULE") inserted some of the include statements into
sections protected by an unrelated #if CONFIG_... statement. This can cause,
depending on the configuration used, warnings like this one:arch/blackfin/mach-bf537/boards/stamp.c:2940: warning: data definition has no type or storage class
arch/blackfin/mach-bf537/boards/stamp.c:2940: warning: type defaults to ‘int’ in declaration of ‘EXPORT_SYMBOL’
arch/blackfin/mach-bf537/boards/stamp.c:2940: warning: parameter names (without types) in function declarationThis patch fixes it by moving the includes out of the #if protected sections.

__kfree_rcu() in rcupdate.h bugs when parameter offset is not a constant
at compile time. Since we build the kgdb_test module with -O0 and it
includes this header file, we hit the bug. So drop the -O0 and mark the
one func we need for the test as noinline (so we can set a breakpoint on
it and have it be hit).Signed-off-by: Sonic Zhang

IRQF_SHARED is not part of the IORESOURCE_IRQ bits. It's expressed by
IORESOURCE_IRQ_SHAREABLE.IORESOURCE_IRQ_HIGHEDGE and IRQF_TRIGGER_HIGH are contradicting
values, an interrupt can hardly be configured for both level and edge
at the same time. This was introduced in commit 45138439(Blackfin
arch: flash memory map and dm9000 resources updating) of course
without any hint in the changelog what the heck this is supposed to

After changing all consumers of atomics to include , we
ran into some compile time errors due to this dependency chain:linux/atomic.h
-> asm/atomic.h
-> asm-generic/atomic-long.hwhere atomic-long.h could use funcs defined later in linux/atomic.h
without a prototype. This patches moves the code that includes
asm-generic/atomic*.h to linux/atomic.h.Archs that need need to select
CONFIG_GENERIC_ATOMIC64 from now on (some of them used to include it
unconditionally).Compile tested on i386 and x86_64 with allnoconfig.

Do not trace arch_local_save_flags(), arch_local_irq_*() and friends.
Although they are marked inline, gcc may still make a function out of
them and add it to the pool of functions that are traced by the function
tracer. This can cause undesirable results (kernel panic, triple faults,
etc).Add the notrace notation to prevent them from ever being traced.

The BF51x's alternative portmux Kconfig options were copy & pasted from
the BF52x, but never tweaked to reflect it. So drop the old options as
they were never used (and were simply wrong), and add the BF51x specific
pieces to the Kconfig and header.Signed-off-by: Mike Frysinger

Back in commit c03c2a87347b849ec927d, we fixed logic in the non-bf54x
GPIO resume code to set the data levels properly before the direction
to avoid spurious line glitches. But we missed the bf54x code paths.
So add the same fix there.Signed-off-by: Mike Frysinger

Re-architect how we save/restore the gpio/port logic that only pertains

The current save logic used in hibernation is to do a MMR load (base +
offset) into a register, and then push that onto the stack. Then when
restoring, pop off the stack into a register followed by a MMR store
(base + offset). These use plenty of 32bit insns rather than 16bit,
are pretty long winded, and full of pipeline bubbles.So, by taking advantage of MMRs that are contiguous, the multi-register
push/pop insn, and register abuse, we can shrink this code considerably.When saving, the new logic does a lot of loads into the data and pointer
registers before executing a single multi-register push insn. Then when
restoring, we do a single multi-register pop insn followed by a lot of
stores. Overall, this allows us to cut the insn count by ~30%, the code
size by ~45%, and drastically reduce the register hazards that trigger
bubbles in the pipeline.Signed-off-by: Mike Frysinger

EVT0 is for emulation, EVT1 is for reset, and EVT4 is the "global int
disable" region. None of these are used by software (or even hardware),
so don't bother saving/restoring them when we hibernate since nothing
ever uses these in Linux (the only thing they would be useful for is
core-memory scratch, but that's just crazy talk).Signed-off-by: Mike Frysinger
