#     mm/gup: Let __get_user_pages_locked() return -EINTR for fatal signal
#     
#     __get_user_pages_locked() will return 0 instead of -EINTR after commit
#     4426e945df588 ("mm/gup: allow VM_FAULT_RETRY for multiple times") which
#     added extra code to allow gup detect fatal signal faster.
#     
#     Restore the original -EINTR behavior.

WARNING: modpost: vmlinux.o(.text.unlikely+0x2b0): Section mismatch in reference from the function early_init_mmu() to the function .init.text:radix__early_init_mmu()
The function early_init_mmu() references
the function __init radix__early_init_mmu().
This is often because early_init_mmu lacks a __init 
annotation or the annotation of radix__early_init_mmu is wrong.
