[PATCH 16/27] asm-generic: introduce generic syscalls.h

Arnd Bergmann
2009-04-30T15:51:32Z

Add a generic syscalls.h with all common system
calls that can not be declared in linux/syscalls.h
because some architectures have unusual signatures.

All prototypes in here can be overriden by the
architecture but default to the most common variant.
