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.

This breaks the build of the KVM selftests:

aarch64/aarch32_id_regs.c:150:16: error: use of undeclared identifier 'ID_AA64PFR0_EL1_ELx_64BIT_ONLY' 150 | return el0 == ID_AA64PFR0_EL1_ELx_64BIT_ONLY; | ^ 1 warning and 1 error generated.

since it's pulled over the changes in 056600ff7330 ("arm64/cpufeature: Replace custom macros with fields from ID_AA64PFR0_EL1") but not updated the test to reflect this.

Thanks for the heads up. I've stashed a fix on top, which hopefully will be in next tomorrow.

Oops sorry about that. I only tested the Perf build and hadn't done the self tests for a few versions.

Thanks for making the fix.
