Subject: [PATCH rt/2.6.31] [RT] kernel/sched.c: Fixup of "implicit declaration of function '_finish_arch_switch'"

From: Wu Zhangjin <[email protected]>

This patch fixes the following error:

kernel/sched.c: In function 'finish_task_switch':
kernel/sched.c:2979: error: implicit declaration of function
'_finish_arch_switch'

The following archs have defined their finish_arch_switch:

$ grep finish_arch_switch -ur arch/
arch/s390/include/asm/system.h:#define finish_arch_switch(prev)
arch/sh/include/asm/system_32.h:#define finish_arch_switch(prev
arch/avr32/include/asm/system.h:#define finish_arch_switch(prev)
arch/mips/include/asm/system.h:#define finish_arch_switch(prev)

Sorry, Just found the "TAB" delete the "h" of the above
_finish_arch_switc, will resend one later.
