#     lib/mpi: Fix building for powerpc with clang
#     
#     0day reports over and over on an powerpc randconfig with clang:
#     
#     lib/mpi/generic_mpih-mul1.c:37:13: error: invalid use of a cast in a
#     inline asm context requiring an l-value: remove the cast or build with
#     -fheinous-gnu-extensions
#     
#     Remove the superfluous casts, which have been done previously for x86
#     and arm32 in commit dea632cadd12 ("lib/mpi: fix build with clang") and
#     commit 7b7c1df2883d ("lib/mpi/longlong.h: fix building with 32-bit
#     x86").

WARNING: modpost: vmlinux.o(.text.unlikely+0x1a0): 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.

WARNING: modpost: vmlinux.o(.text.unlikely+0x1ac): Section mismatch in reference from the function early_init_mmu() to the function .init.text:hash__early_init_mmu()
The function early_init_mmu() references
the function __init hash__early_init_mmu().
This is often because early_init_mmu lacks a __init 
annotation or the annotation of hash__early_init_mmu is wrong.
