Subject: [PATCH V2] powerpc: add little endian flag to syscall_get_arch()
Date: Mon,  8 Dec 2014 12:58:07 -0500	[thread overview]
Message-ID: <> (raw)

Since both ppc and ppc64 have LE variants which are now reported by uname, add
that flag (__AUDIT_ARCH_LE) to syscall_get_arch() and add AUDIT_ARCH_PPC*LE

Without this,  perf trace and auditctl fail.

Mainline kernel reports ppc64le (per a058801) but there is no matching


v1 -> v2:
	Added ";" at the end of the #ifdef-protected line so it actually compiles
