Hi Greg, Sasha,
The config malta_qemu_32r6_defconfig for mips fails to build for gcc-10+. Please apply 1d7ba0165d82 ("mips: Do not include hi and lo in clobber list for R6") to 4.14-stable to 5.12-stable branches. It will apply cleanly to 5.9-stable to 5.12-stable. I will send the backport for 4.14-stable, 4.19-stable and 5.4-stable.
-- Regards Sudip
