smp, hexagon: kill SMP single function call interrupt

2014-04-04T23:20:01+00:00

Commit 9a46ad6d6df3b54 "smp: make smp_call_function_many() use logic
similar to smp_call_function_single()" has unified the way to handle
single and multiple cross-CPU function calls. Now only one intterupt
is needed for architecture specific code to support generic SMP function
call interfaces, so kill the redundant single function call interrupt.

arch: hexagon: kernel: hexagon_ksyms.c: export related symbols which various modules need

2014-04-04T23:20:00+00:00

Need export all related functions and symbols for various modules with
allmodconfig. The related errors:

    MODPOST 2879 modules
  ERROR: "__vmyield" [sound/sound_firmware.ko] undefined!
  ERROR: "__phys_offset" [sound/drivers/snd-dummy.ko] undefined!
  ERROR: "ioremap_nocache" [drivers/char/ipmi/ipmi_si.ko] undefined!
  ERROR: "__iounmap" [drivers/char/ipmi/ipmi_si.ko] undefined!
  ...

For including files, need "linux/*" first, then "asm/*". All related
included files and symbols need be sorted by alphabetical order.

arch: hexagon: kernel: reset.c: use function pointer instead of function for pm_power_off and export it

2014-04-04T23:20:00+00:00

'pm_power_off' is a function pointer, not a function, so need change
its type, and also need export it, or can not pass compiling with
allmodconfig. The related error:

    MODPOST 2879 modules
  ERROR: "pm_power_off" [drivers/char/ipmi/ipmi_poweroff.ko] undefined!

hexagon: remove unnecessary prom.h includes

2013-10-10T01:04:02+00:00

Hexagon does not have a prom.h header, so it is probably broken with
CONFIG_OF enabled. In any case, remove unnecessary prom.h include in
preparation to make prom.h optional.

hexagon: delete __cpuinit usage from all hexagon files

2013-07-14T23:36:55+00:00

The __cpuinit type of throwaway sections might have made sense
some time ago when RAM was more constrained, but now the savings
do not offset the cost and complications.  For example, the fix in
commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
is a good example of the nasty type of bugs that can be created
with improper use of the various __init prefixes.

After a discussion on LKML[1] it was decided that cpuinit should go
the way of devinit and be phased out.  Once all the users are gone,
we can then finally remove the macros themselves from linux/init.h.

Note that some harmless section mismatch warnings may result, since
notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c)
are flagged as __cpuinit  -- so if we remove the __cpuinit from
arch specific callers, we will also get section mismatch warnings.
As an intermediate step, we intend to turn the linux/init.h cpuinit
content into no-ops as early as possible, since that will get rid
of these warnings.  In any case, they are temporary and harmless.

This removes all the arch/hexagon uses of the __cpuinit macros from
all C files.  Currently hexagon does not have any __CPUINIT used in
assembly files.
