hexagon: Fix build failures in linux-next

2014-12-16T19:27:12+00:00

hexagon:defconfig fails to build in linux-next since commit 332fd7c4fef5
("genirq: Generic chip: Change irq_reg_{readl,writel} arguments").

The primary build failure is

arch/hexagon/include/asm/cacheflush.h: In function 'copy_to_user_page':
arch/hexagon/include/asm/cacheflush.h:89:22: error: 'VM_EXEC' undeclared

This is the result of including of  from ,
which is now necessary due to the use of readl and writel from irq.h.
This causes recursive inclusions in hexagon code; cacheflush.h is included
from mm.h prior to the definition of VM_EXEC.

Fix the problem by moving copy_to_user_page from the hexagon include file to
arch/hexagon/mm/cache.c, similar to other architectures. After this change,
several redefinitions of readl and writel are reported. Those are caused
by recursive inclusions of io.h and asm/cacheflush.h. Fix those problems by
reducing the number of files included from those files. Also, it was necessary
to stop including asm-generic/cacheflush.h from asm/cacheflush.h. Instead,
functionality originally provided by asm-generic/cacheflush.h is now coded
in asm/cacheflush.h directly.

hexagon: Use get_signal() signal_setup_done()

2014-08-06T11:02:14+00:00

Use the more generic functions get_signal() signal_setup_done()
for signal delivery.

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!
