[PATCH v1 1/4] powerpc: Cleanup asm-prototypes.c

Sat Mar 5 04:04:02 AEDT 2022


Last call to sys_swapcontext() from ASM was removed by
commit fbcee2ebe8ed ("powerpc/32: Always save non volatile GPRs at
syscall entry")

sys_debug_setcontext() prototype not needed anymore since
commit f3675644e172 ("powerpc/syscalls: signal_{32, 64} - switch
to SYSCALL_DEFINE")

sys_switch_endian() prototype not needed anymore since
commit 81dac8177862 ("powerpc/64: Make sys_switch_endian() traceable")

_mount() prototype is already in asm/ftrace.h
