Subject: [PATCH v8 4/8] tools: arm64: Update sysreg.h header files
From: James Clark <james.clark@....com>
Created with the following:
cp include/linux/kasan-tags.h tools/include/linux/
cp arch/arm64/include/asm/sysreg.h tools/arch/arm64/include/asm/
Update the tools copy of sysreg.h so that the next commit to add a new
register doesn't have unrelated changes in it. Because the new version
of sysreg.h includes kasan-tags.h, that file also now needs to be copied
into tools.
