Build failures:

ia64:defconfig
ia64:allnoconfig

drivers/built-in.o: In function `efi_mem_attributes':
(.text+0xde962): undefined reference to `memmap'
drivers/built-in.o: In function `efi_mem_attributes':
(.text+0xde971): undefined reference to `memmap'

Bisect points to 'efi, x86: Rearrange efi_mem_attributes()'.
On a side note, 'memmap' is really a bad name for a global variable,
As the patch desciption suggests, the variable does not exist for ia64,
so the build failure is not entirely unexpected.

powerpc:ppc64e_defconfig
powerpc:85xx/sbc8548_defconfig

arch/powerpc/sysdev/fsl_pci.c: In function 'fsl_pci_mcheck_exception':
arch/powerpc/sysdev/fsl_pci.c:1002:4: error: passing argument 2 of 'probe_kernel_read' makes pointer from integer without a cast

Bisect points to 'uaccess: reimplement probe_kernel_address() using
probe_kernel_read()'.
