Powerpc builds may fail with the following build error.
Error log: In file included from ./arch/powerpc/include/asm/mmu_context.h:11:0, from ./include/linux/mmu_context.h:4, from mm/mmu_context.c:8: ./arch/powerpc/include/asm/cputhreads.h: In function 'get_tensr': ./arch/powerpc/include/asm/cputhreads.h:101:2: error: implicit declaration of function 'cpu_has_feature'
The problem can be triggered by configuring ppc64e_defconfig and selecting CONFIG_TICK_CPU_ACCOUNTING instead of CONFIG_VIRT_CPU_ACCOUNTING_NATIVE.
Fixes: b92a226e5284 ("powerpc: Move cpu_has_feature() to a separate file") Signed-off-by: Guenter Roeck <linux@roeck-us.net> --- This is the second attempt to fix this problem. The first attempt was with commit 546c4402c574 ("powerpc/vdso: Add missing include file"). This was not complete because it added the include file to an affected source file, not to the file where cpu_has_feature() was used.
Build tested all default configurations to ensure that this patch does not introduce a regression.
