Subject: [PATCH] x86/syscalls/32: ignore arch_prctl for other architectures
Date: Thu, 23 Mar 2017 16:18:51 +0100 [thread overview]
Message-ID: <20170323151904.706286-1-arnd@arndb.de> (raw)
sys_arch_prctl is only provided on x86, and there is no reason
to add it elsewhere. However, including it on the 32-bit syscall
table caused a warning for most configurations on non-x86:
:1328:2: warning: #warning syscall arch_prctl not implemented [-Wcpp]
This adds an exception to the syscall table checking script.
Fixes: 79170fda313e ("x86/syscalls/32: Wire up arch_prctl on x86-32")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>

Thomas, can you apply this on top of the x86 patch?
