ARM/audit: include audit header and fix audit arch
Both bugs being fixed were introduced in: 29ef73b7a823b77a7cd0bdd7d7cded3fb6c2587b Include linux/audit.h to fix below build errors: CC arch/arm/kernel/ptrace.o arch/arm/kernel/ptrace.c: In function 'syscall_trace': arch/arm/kernel/ptrace.c:919: error: implicit declaration of function 'audit_syscall_exit' arch/arm/kernel/ptrace.c:921: error: implicit declaration of function 'audit_syscall_entry' arch/arm/kernel/ptrace.c:921: error: 'AUDIT_ARCH_ARMEB' undeclared (first use in this function) arch/arm/kernel/ptrace.c:921: error: (Each undeclared identifier is reported only once arch/arm/kernel/ptrace.c:921: error: for each function it appears in.) make[1]: *** [arch/arm/kernel/ptrace.o] Error 1 make: *** [arch/arm/kernel] Error 2 This part of the patch is: Reported-by: Axel Lin <axel.lin@gmail.com> Reported-by: Peter Ujfalusi <peter.ujfalusi@ti.com> (They both provided patches to fix it) This patch also (at the request of the list) fixes the fact that ARM has both LE and BE versions however the audit code was called as if it was always BE. If audit userspace were to try to interpret the bits it got from a LE system it would obviously do so incorrectly. Fix this by using the right arch flag on the right system. This part of the patch is: Reported-by: Russell King - ARM Linux <linux@arm.linux.org.uk> Signed-off-by: Eric Paris <eparis@redhat.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
