[POWERPC] Fix is_power_of_4(x) compile error (8dabba5d) · Commits · 戴 / test

When building an 85xx kernel we get: CC arch/powerpc/mm/pgtable_32.o arch/powerpc/mm/pgtable_32.c: In function 'io_block_mapping': arch/powerpc/mm/pgtable_32.c:330: error: expected identifier before '(' token arch/powerpc/mm/pgtable_32.c:330: error: expected statement before ')' token The is_power_of_2(x) fixup patch left an extra ')' on the is_power_of_4 macro. There is a similiar issue on the arch/ppc side. Signed-off-by:
