KVM: arm64: Remove __hyp_text macro, use build rules instead
With nVHE code now fully separated from the rest of the kernel, the effects of the __hyp_text macro (which had to be applied on all nVHE code) can be achieved with build rules instead. The macro used to: (a) move code to .hyp.text ELF section, now done by renaming .text using `objcopy`, and (b) `notrace` and `__noscs` would negate effects of CC_FLAGS_FTRACE and CC_FLAGS_SCS, respectivelly, now those flags are erased from KBUILD_CFLAGS (same way as in EFI stub). Note that by removing __hyp_text from code shared with VHE, all VHE code is now compiled into .text and without `notrace` and `__noscs`. Use of '.pushsection .hyp.text' removed from assembly files as this is now also covered by the build rules. For MAINTAINERS: if needed to re-run, uses of macro were removed with the following command. Formatting was fixed up manually. find arch/arm64/kvm/hyp -type f -name '*.c' -o -name '*.h' \ -exec sed -i 's/ __hyp_text//g' {} + Signed-off-by: David Brazdil <dbrazdil@google.com> Signed-off-by: Marc Zyngier <maz@kernel.org> Link: https://lore.kernel.org/r/20200625131420.71444-15-dbrazdil@google.com
