Sorry, this was a special case. This was a patch in the part of Andrew's series that gets rebased on top of the rest of linux-next each day (as that part has dependencies on other things in linux-next). In this case, the resolution was to drop the patch entirely as it had become unnecessary. This was it: From: Andrew Morton Subject: arch/x86/kernel/cpu/common.c: fix warning x86_64 allnoconfig: arch/x86/kernel/cpu/common.c: In function 'syscall_init': arch/x86/kernel/cpu/common.c:1225: warning: right shift count >= width of type Fixes: a76c7f4604937bc ("x86/asm/entry/64: Fold syscall32_cpu_init() into its sole user") Cc: Denys Vlasenko Cc: Andy Lutomirski Cc: H.
