Subject: selftests/powerpc: Standardise TM calls
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=da3ddc3b5fea695f7b2fa89c4ca17dfd529293d2;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

selftests/powerpc: Standardise TM calls

Currently tbegin, tend etc are written as opcodes or asm instructions. So
standardise these to asm instructions.
