Sorry about that.  But that does not look to be consistent.

10:57:35 > git grep 'noinstr' arch/x86/entry/common.c

arch/x86/entry/common.c:idtentry_state_t noinstr idtentry_enter(struct pt_regs *regs)
arch/x86/entry/common.c:void noinstr idtentry_exit(struct pt_regs *regs, idtentry_state_t state)
arch/x86/entry/common.c:void noinstr idtentry_enter_user(struct pt_regs *regs)
arch/x86/entry/common.c:void noinstr idtentry_exit_user(struct pt_regs *regs)
...

Are the above 'wrong'?  Is it worth me sending a patch?

I've changed my code,
Ira
