From 8031d1f678c2b06733c8f9028b413194b47c33ab Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 15 Dec 2022 17:29:38 +0100 Subject: crypto: wp512 - disable kmsan checks in wp512_process_buffer() The memory sanitizer causes excessive register spills in this function: crypto/wp512.c:782:13: error: stack frame size (2104) exceeds limit (2048) in 'wp512_process_buffer' [-Werror,-Wframe-larger-than] Assume that this one is safe, and mark it as needing no checks to get the stack usage back down to the normal level.
