17 years agoDon't compile the PMU power driver on 64-bit PowerPC
Paul Mackerras [Sun, 22 Jul 2007 00:41:39 +0000 (10:41 +1000)]
Don't compile the PMU power driver on 64-bit PowerPC

As reported by Stephen Rothwell, an allmodconfig build on 64-bit
PowerPC reports these errors:

ERROR: "pmu_batteries" [drivers/power/pmu_battery.ko] undefined!
ERROR: "pmu_battery_count" [drivers/power/pmu_battery.ko] undefined!
ERROR: "pmu_power_flags" [drivers/power/pmu_battery.ko] undefined!

This fixes the problem by not building pmu_battery.ko on ppc64.  There
are no battery-powered ppc64 machines with an Apple PMU, and we can be
reasonably confident there never will be.

9p: Don't use binary sysctl numbers.

The recent 9p commit: bd238fb431f31989898423c8b6496bc8c4204a86 that
supposedly only moved files also introduced a new 9p sysctl interface
that did not properly register it's sysctl binary numbers.

And since it was only for debugging clearly did not need a binary fast
path in any case.  So this patch just remove the binary numbers.

See Documentation/sysctl/ctl_unnumbered.txt for more details.

While I was at it I cleaned up the sysctl initializers a little as
well so there is less to read.

17 years agox86: Replace NSC/Cyrix specific chipset access macros by inlined functions.
Juergen Beisert [Sun, 22 Jul 2007 09:12:38 +0000 (11:12 +0200)]
x86: Replace NSC/Cyrix specific chipset access macros by inlined functions.

Due to index register access ordering problems, when using macros a line
like this fails (and does nothing):

setCx86(CX86_CCR2, getCx86(CX86_CCR2) | 0x88);

With inlined functions this line will work as expected.

Note about a side effect: Seems on Geode GX1 based systems the
"suspend on halt power saving feature" was never enabled due to this
wrong macro expansion. With inlined functions it will be enabled, but
this will stop the TSC when the CPU runs into a HLT instruction.
Kernel output something like this:
Clocksource tsc unstable (delta = -472746897 ns)

This is the 3rd version of this patch.

 - Adding missed arch/i386/kernel/cpu/mtrr/state.c

[PATCH] get rid of AVC_PATH postponed treatment

        Selinux folks had been complaining about the lack of AVC_PATH
records when audit is disabled.  I must admit my stupidity - I assumed
that avc_audit() really couldn't use audit_log_d_path() because of
deadlocks (== could be called with dcache_lock or vfsmount_lock held).
Shouldn't have made that assumption - it never gets called that way.
It _is_ called under spinlocks, but not those.

        Since audit_log_d_path() uses ab->gfp_mask for allocations,
kmalloc() in there is not a problem.  IOW, the simple fix is sufficient:
let's rip AUDIT_AVC_PATH out and simply generate pathname as part of main
record.  It's trivial to do.

Classic 32-bit PowerPC CPUs, and the early 64-bit PowerPC CPUs, don't
provide a way to prevent execution from readable pages, that is, the
MMU doesn't distinguish between data reads and instruction reads,
although a different exception is taken for faults in data accesses
and instruction accesses.

Commit 9ba4ace39fdfe22268daca9f28c5df384ae462cf, in the course of
fixing another bug, added a check that meant that a page fault due
to an instruction access would fail if the vma did not have the
VM_EXEC flag set.  This gives an inconsistent enforcement on these
CPUs of the no-execute status of the vma (since reading from the page
is sufficient to allow subsequent execution from it), and causes old
versions of ppc32 glibc (2.2 and earlier) to fail, since they rely
on executing the word before the GOT but don't have it marked
executable.

This fixes the problem by allowing execution from readable (or writable)
areas on CPUs which do not provide separate control over data and
instruction reads.
