From: Nikolay Borisov Date: Thu, 13 Jun 2024 11:08:37 +0000 (+0300) Subject: x86/boot: Remove unused function __fortify_panic() X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=71315037cb7d40cdb2f4fbefad31927f6e6caba5;p=linux.git x86/boot: Remove unused function __fortify_panic() That function is only used when the kernel is compiled with FORTIFY_SOURCE and when the kernel proper string.h header is used. The decompressor code doesn't use the kernel proper header but has local copy which doesn't contain any fortified implementations of the various string functions. As such __fortify_panic() can never be called from the decompressor so remove it.
