[PATCH 3/6][RFC] audit: __audit_syscall_entry: ignore arch arg and call syscall_get_arch() directly
From: Richard Guy Briggs
Date: Wed Mar 05 2014 - 16:29:15 EST
Since all the callers of syscall_get_arch() presently pass "current" and none
of the arch-specific syscall_get_arch() implementations use the regs parameter,
ignore the passed in arch parameter to __audit_syscall_entry() and call
syscall_get_arch() directly.
Change the audit header file from the kernel internal to the user api version
to get the architecture numbers, but to avoid a circular header reference
between audit and syscall.h
