[Paul Mackerras]

Linus,

Please do:

git pull \
git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc.git master

to get some powerpc bug fixes, including one from Ben H that fixes an
error in our vmlinux.lds.S which is currently making our kernels
unbootable.

Thanks,
Paul.

    [POWERPC] Fix powerpc vmlinux.lds.S
    
    Sam's recent change in 7664709b44a13e2e0b545e2dd8e7b8797a1748dc
    broke things for us because we ended up with *(.text.*) before
    *(.text), whereas previously *(.text) was first.  This was
    important because the start of the text section contains the
    kernel entry point.
    
    In fact, we don't need that *(.text.*) thing anymore and it
    incorrectly matched .text.init.refok, thus putting it before
    .text. .. ouch !

    [POWERPC] Fix typo: MMCR0_PMA0 != MMCR0_PMAO
    
    pmc.c has:
    
    #ifndef MMCR0_PMA0
    #define MMCR0_PMA0     0
    
    This one took a while to find.  Unfortunately its the wrong define
    (number 0 vs letter O). Its probably worth removing this override, since
    if our includes get screwed up we will have the same (hard to debug)
    failure.
    
    Fix it simply for now, so that we can backport to stable.

    [POWERPC] Add missing pmc_type fields in cpu_table
    
    A number of cpu_table entries were missing the pmc_type field,
    which means that the sysfs entries for the performance monitor
    counters don't get created.  This adds them.

    [POWERPC] Fix smp_call_function to be preempt-safe
    
    smp_call_function_map() was not safe against preemption to another
    cpu: its test for removing self from map was outside the spinlock.
    Rearrange it a little to fix that.
    
    smp_call_function_single() was also wrong: now get_cpu() before
    excluding self, as other architectures do.
