Subject: [PATCH 15/33] x86/asm/crypto: Create stack frames in crypto functions
Date: Thu, 21 Jan 2016 16:49:19 -0600	[thread overview]
Message-ID: <6c20192bcf1102ae18ae5a242cabf30ce9b29895.1453405861.git.jpoimboe@redhat.com> (raw)
In-Reply-To: <cover.1453405861.git.jpoimboe@redhat.com>

The crypto code has several callable non-leaf functions which don't
honor CONFIG_FRAME_POINTER, which can result in bad stack traces.

Create stack frames for them when CONFIG_FRAME_POINTER is enabled.
