I don't think we want to blindly revert all that. Some of them actually
made sense and did clean up things irrespective of the asm-inline issue.
In particular I like the jump-label one. The cpufeature one OTOh, yeah,
I'd love to get that reverted.
And as a note; the normal commit quoting style is:
d5a581d84ae6 ("x86/cpufeature: Macrofy inline assembly code to work around GCC inlining bugs")
