From bf619faeced5c2beb32a39559e1f1117f88fd702 Mon Sep 17 00:00:00 2001 From: Russell King Date: Fri, 21 Sep 2012 17:55:20 +0100 Subject: [PATCH] ARM: reserve syscall 378 for kcmp kcmp has appeared on x86, but has not been noticed because checksyscalls.sh is broken at the moment. Reserve ARM syscall 378 for this should we ever need it, and add an __IGNORE entry for this unimplemented syscall.
