It's definitely .24 given the dates for the SYS releases he notes. The
diffstat between the two is relatively short , but I can't see
anything that can be related. This code runs so early, during real
mode startup, that my only suspects are:
arch/x86/kernel/head_32.S | 2 +-
arch/x86/kernel/smpboot_64.c | 2 +-
include/asm-generic/tlb.h | 3 -
include/asm-x86/byteorder.h | 4 +-
include/asm-x86/msr.h | 74 +++++++++--------
but none of those are obviously the culprit to me...
Werner, the initcall_debug trace would be most helpful; without that
I'm not sure how much progress we can make on this.
