user/sven/linux.git/arch/powerpc/kernel/setup_32.c, branch v4.9.147

Merge branch 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild

2016-10-14T21:26:58Z

Pull kbuild updates from Michal Marek: - EXPORT_SYMBOL for asm source by Al Viro. This does bring a regression, because genksyms no longer generates checksums for these symbols (CONFIG_MODVERSIONS). Nick Piggin is working on a patch to fix this. Plus, we are talking about functions like strcpy(), which rarely change prototypes. - Fixes for PPC fallout of the above by Stephen Rothwell and Nick Piggin - fixdep speedup by Alexey Dobriyan. - preparatory work by Nick Piggin to allow architectures to build with -ffunction-sections, -fdata-sections and --gc-sections - CONFIG_THIN_ARCHIVES support by Stephen Rothwell - fix for filenames with colons in the initramfs source by me. * 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild: (22 commits) initramfs: Escape colons in depfile ppc: there is no clear_pages to export powerpc/64: whitelist unresolved modversions CRCs kbuild: -ffunction-sections fix for archs with conflicting sections kbuild: add arch specific post-link Makefile kbuild: allow archs to select link dead code/data elimination kbuild: allow architectures to use thin archives instead of ld -r kbuild: Regenerate genksyms lexer kbuild: genksyms fix for typeof handling fixdep: faster CONFIG_ search ia64: move exports to definitions sparc32: debride memcpy.S a bit [sparc] unify 32bit and 64bit string.h sparc: move exports to definitions ppc: move exports to definitions arm: move exports to definitions s390: move exports to definitions m68k: move exports to definitions alpha: move exports to actual definitions x86: move exports to actual definitions ...

powerpc/32: Fix crash during static key init

2016-08-10T09:41:58Z

We cannot do those initializations from apply_feature_fixups() as this function runs in a very restricted environment on 32-bit where the kernel isn't running at its linked address and the PTRRELOC() macro must be used for any global accesss. Instead, split them into a separtate steup_feature_keys() function which is called in a more suitable spot on ppc32.

powerpc: Move cpu_has_feature() to a separate file

2016-08-01T01:15:03Z

We plan to use jump label for cpu_has_feature(). In order to implement this we need to include the linux/jump_label.h in asm/cputable.h. Unfortunately if we do that it leads to an include loop. The root of the problem seems to be that reg.h needs cputable.h (for CPU_FTRs), and then cputable.h via jump_label.h eventually pulls in hw_irq.h which needs reg.h (for MSR_EE). So move cpu_has_feature() to a separate file on its own.

powerpc: Merge 32-bit and 64-bit setup_arch()

2016-07-21T09:17:46Z

There is little enough differences now. mpe: Add a/p/k/setup.h to contain the prototypes and empty versions of functions we need, rather than using weak functions. Add a few other empty versions to avoid as many #ifdefs as possible in the code. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Michael Ellerman

powerpc: Re-order setup_panic()

2016-07-21T09:17:23Z

Do it right after probe_machine() since it's about testing ppc_md, and put the test in the common code. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Michael Ellerman

powerpc: Re-order the call to smp_setup_cpu_maps()

2016-07-21T09:14:32Z

It makes more sense to do it before intializing xmon() as xmon might use the info in there. We do want to register the console early though in case we want some functioning printk's in the cpu map setup. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Michael Ellerman

powerpc: Get rid of ppc_md.init_early()

It is now called right after platform probe, so the probe function can just do the job. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Michael Ellerman
