It requires the architecture-independent macro definitions from this patch series: The long-term goal here is to add support for building the kernel with -ffunction-sections -fdata-sections. This requires renaming all the magic section names in the kernel of the form .text.foo, .data.foo, .bss.foo, and .rodata.foo to not have collisions with sections generated for code like: static int nosave = 0; /* -fdata-sections places in .data.nosave */ static void head(); /* -ffunction-sections places in .text.head */ Note that these patches have not been boot-tested (aside from testing the analogous changes on x86), since I don't have access to the appropriate hardware. -Tim Abbott Tim Abbott (8): powerpc: Remove unused __page_aligned macro. powerpc: share .data output section definition between 32 and 64 bits. powerpc: Use macros for .data.page_aligned section. powerpc: use NOSAVE_DATA macro for .data.nosave section. powerpc: use new macro for .data.cacheline_aligned section. powerpc: use new macros for .data.init_task. powerpc: use new macro for .data.read_mostly section. powerpc: convert to new generic read_mostly support. arch/powerpc/Kconfig | 3 ++ arch/powerpc/include/asm/cache.h | 4 -- arch/powerpc/include/asm/page_64.h | 8 ---- arch/powerpc/kernel/init_task.c | 3 +- arch/powerpc/kernel/machine_kexec_64.c | 4 +- arch/powerpc/kernel/vdso.c | 3 +- arch/powerpc/kernel/vdso32/vdso32_wrapper.S | 3 +- arch/powerpc/kernel/vdso64/vdso64_wrapper.S | 3 +- arch/powerpc/kernel/vmlinux.lds.S | 47 ++++++-------------------- 9 files changed, 23 insertions(+), 55 deletions(-)
