powerpc/mm/radix: mark __radix__flush_tlb_range_psize() as __always_inline
This prepares to move CONFIG_OPTIMIZE_INLINING from x86 to a common place. We need to eliminate potential issues beforehand. If it is enabled for powerpc, the following error is reported: arch/powerpc/mm/tlb-radix.c: In function '__radix__flush_tlb_range_psize': arch/powerpc/mm/tlb-radix.c:104:2: error: asm operand 3 probably doesn't match constraints [-Werror] asm volatile(PPC_TLBIEL(%0, %4, %3, %2, %1) ^~~ arch/powerpc/mm/tlb-radix.c:104:2: error: impossible constraint in 'asm' Link: http://lkml.kernel.org/r/20190423034959.13525-10-yamada.masahiro@socionext.com Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Cc: Arnd Bergmann <arnd@arndb.de> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Boris Brezillon <bbrezillon@kernel.org> Cc: Borislav Petkov <bp@suse.de> Cc: Brian Norris <computersforpeace@gmail.com> Cc: Christophe Leroy <christophe.leroy@c-s.fr> Cc: David Woodhouse <dwmw2@infradead.org> Cc: Heiko Carstens <heiko.carstens@de.ibm.com> Cc: "H.
