With built-in scsi disk driver, the final link fails with a following error: `.exit.text' referenced in section `.rodata' of drivers/built-in.o: defined in discarded section `.exit.text' of drivers/built-in.o This happens with -Os (CONFIG_CC_OPTIMIZE_FOR_SIZE=y) with all gcc-4 versions, and also with -O2 and gcc-4.3. The problem is in sd.c:sd_major() being inlined into __exit function exit_sd(), and the compiler generating a jump table in .rodata section for the 'switch' statement in sd_major(). So we have references to discarded section. Fixed with a big hammer in the form of -fno-jump-tables. Note that jump tables vs. discarded sections is a generic problem, other architectures are just lucky not to suffer from it. But with a slightly more complex switch/case statement it can be reproduced on x86 as well. So maybe at some point we should consider -fno-jump-tables as a generic compile option...

This fixes some of the alpha-specific build problems, except a) modpost warning about COMMON symbol "saved_config" and b) nasty final link failure with gcc-4.x, -Os and scsi-disk driver configured built-in (due to jump table in .rodata referencing discarded .exit.text). - build failure with gcc-4.2.x: fix up casts in cia_io* routines to avoid warnings ('discards qualifiers from pointer target type'), which are failures, thanks to -Werror; - modpost warnings: add missing __init qualifier for titan and marvel; for non-generic build, move machine vectors from .data to .data.init.refok section; - unbreak CPU-specific optimization: rearrange cpuflags-y assignments so that extended -mcpu value (ev56, pca56, ev67) overrides basic one (ev5, ev6) and not vice versa.

- binutils 2.7 is far below the current minimum supported version, and there's therefore no longer a need for an extra test - since even gcc 3.2 already supports all options used we can use them unconditionally Signed-off-by: NAdrian Bunk <bunk@stusta.de> Cc: Richard Henderson <rth@twiddle.net> Cc: Ivan Kokshaysky <ink@jurassic.park.msu.ru> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

The variable CFLAGS is a wellknown variable and the usage by kbuild may result in unexpected behaviour. On top of that several people over time has asked for a way to pass in additional flags to gcc. This patch replace use of CFLAGS with KBUILD_CFLAGS all over the tree and enabling one to use: make CFLAGS=... to specify additional gcc commandline options. One usecase is when trying to find gcc bugs but other use cases has been requested too. Patch was tested on following architectures: alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k Test was simple to do a defconfig build, apply the patch and check that nothing got rebuild.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
