__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:

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 do. Acked-by:

After changing all consumers of atomics to include <linux/atomic.h>, we ran into some compile time errors due to this dependency chain: linux/atomic.h -> asm/atomic.h -> asm-generic/atomic-long.h where 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 <asm-generic/atomic64.h> 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. Signed-off-by:

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: -

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).
