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!
