Subject: [PATCH 2/4] s390: make STACK_FRAME_OVERHEAD available via asm-offsets.h
Date: Tue, 12 Oct 2021 15:38:00 +0200 [thread overview]
Message-ID: <20211012133802.2460757-3-hca@linux.ibm.com> (raw)
In-Reply-To: <20211012133802.2460757-1-hca@linux.ibm.com>
Make STACK_FRAME_OVERHEAD available via asm-offsets.h. This allows to
add s390 specific asm code to e.g. ftrace samples, without requiring
to add random header files, which might cause all sort of problems on
other architectures. asm-offsets.h can be assumed to be non-problematic.
