Romain Naour e449b6b707 mips: Do not include hi and lo in clobber list for R6 ... commit 1d7ba0165d upstream >From [1] "GCC 10 (PR 91233) won't silently allow registers that are not architecturally available to be present in the clobber list anymore, resulting in build failure for mips*r6 targets in form of: ... .../sysdep.h:146:2: error: the register ‘lo’ cannot be clobbered in ‘asm’ for the current target 146 | __asm__ volatile ( \ | ^~~~~~~ This is because base R6 ISA doesn't define hi and lo registers w/o DSP extension. This patch provides the alternative clobber list for r6 targets that won't include those registers." Since kernel 5.4 and mips support for generic vDSO [2], the kernel fail to build for mips r6 cpus with gcc 10 for the same reason as glibc.
