This reverts commit 08e86d42e2 which is
commit 9841c423164787feb8f1442f922b7d80a70c82f1 upstream.
As Gunter reports:
Building loongarch:defconfig ... failed
--------------
Error log:
<stdin>:569:2: warning: #warning syscall fstat not implemented [-Wcpp]
arch/loongarch/kernel/setup.c: In function 'arch_cpu_finalize_init':
arch/loongarch/kernel/setup.c:86:9: error: implicit declaration of function 'alternative_instructions'
Actually introduced in v6.1.44 with commit 08e86d42e2 ("loongarch/cpu:
Switch to arch_cpu_finalize_init()"). Alternative instruction support
was only introduced for loongarch in v6.2 with commit 19e5eb15b00c
("LoongArch: Add alternative runtime patching mechanism").
So revert it from 6.1.y.
