I can't see this compile failure posted anywhere:
http://test.kernel.org/results/IBM/126049/build/debug/stderr
arch/x86/vdso/vdso32/sigreturn.S: Assembler messages:
arch/x86/vdso/vdso32/sigreturn.S:23: Error: suffix or operands invalid for `pop'
arch/x86/vdso/vdso32/syscall.S:25: Error: suffix or operands invalid for `pop'
make[1]: *** [arch/x86/vdso/vdso32/syscall.o] Error 1
make: *** [arch/x86/vdso] Error 2
I see those on one build machine but not on another, so I thought
that it was a tools issue...
Nor this one:
http://test.kernel.org/results/IBM/126096/build/debug/stderr
drivers/char/hvcs.c: In function ‘hvcs_open’:
drivers/char/hvcs.c:1180: error: wrong type argument to unary exclamation mark
