Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fix from Will Deacon:
"One trivial fix for -rc8/final that ensures that the script used to
detect RELR relocation support in the toolchain works correctly when
$CC contains quotes. Although it fails safely (by failing to detect
the support when it exists), it would be nice to have this fixed in
5.4 given that it was only introduced in the last merge window.
Summary:
- Handle CC variables containing quotes in tools-support-relr.sh
script"
