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")
