32-bit x86 defconfig still doesn't build:

 arch/x86/events/intel/ds.c: In function ‘dsalloc’:
 arch/x86/events/intel/ds.c:296:6: error: implicit declaration of function ‘kaiser_add_mapping’; did you mean ‘kgid_has_mapping’? [-Werror=implicit-function-declaration]

Also, could you please use proper subsystem tags, instead of:

  Subject: x86, kaiser: Disable global pages by default with KAISER

Please do something like:

  Subject: x86/mm/kaiser: Disable global pages by default with KAISER

Thanks,

	Ingo
