Subject: powerpc/mce: Move 64-bit machine check code into mce.c
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ccd3cd361341b71ae2afa596f6b470fcb32a916e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

powerpc/mce: Move 64-bit machine check code into mce.c

We already have mce.c which is built for 64bit and contains other parts
of the machine check code, so move these bits in there too.
