powerpc/boot: Ensure _zimage_start is a weak symbol

2018-11-21T08:21:57Z

[ Upstream commit ee9d21b3b3583712029a0db65a4b7c081d08d3b3 ] When building with clang crt0's _zimage_start is not marked weak, which breaks the build when linking the kernel image: $ objdump -t arch/powerpc/boot/crt0.o |grep _zimage_start$ 0000000000000058 g .text 0000000000000000 _zimage_start ld: arch/powerpc/boot/wrapper.a(crt0.o): in function '_zimage_start': (.text+0x58): multiple definition of '_zimage_start'; arch/powerpc/boot/pseries-head.o:(.text+0x0): first defined here Clang requires the .weak directive to appear after the symbol is declared. The binutils manual says: This directive sets the weak attribute on the comma separated list of symbol names. If the symbols do not already exist, they will be created. So it appears this is different with clang. The only reference I could see for this was an OpenBSD mailing list post[1]. Changing it to be after the declaration fixes building with Clang, and still works with GCC. $ objdump -t arch/powerpc/boot/crt0.o |grep _zimage_start$ 0000000000000058 w .text 0000000000000000 _zimage_start Reported to clang as https://bugs.llvm.org/show_bug.cgi?id=38921 [1] https://groups.google.com/forum/#!topic/fa.openbsd.tech/PAgKKen2YCY Signed-off-by: Joel Stanley Reviewed-by: Nick Desaulniers Signed-off-by: Michael Ellerman Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman

powerpc/kbuild: Remove CROSS32 defines from top level powerpc Makefile

Switch VDSO32 build over to use CROSS32_COMPILE directly, and have it pass in -m32 after the standard c_flags. This allows endianness overrides to be removed and the endian and bitness flags moved into standard flags variables. Signed-off-by: Nicholas Piggin Signed-off-by: Michael Ellerman

powerpc: remove retired sbc834x support

2018-05-03T12:32:30Z

I no longer have a functional version of this board for even the most basic sanity boot testing, and they have not been available for purchase for quite some years now. There is no point in adding a burden to testing coverage that does walk all the possible defconfigs, so with all the above in mind, it makes sense to remove it. Of course it will remain in the git history for anyone who happens to stumble on one and wants to tinker with it. Signed-off-by: Paul Gortmaker Signed-off-by: Michael Ellerman
