Disable G5 NAP mode during SMU commands on U3

2008-02-26T00:14:08+00:00

patch 592a607bbc053bc6f614a0e619326009f4b3829e in mainline.

It appears that with the U3 northbridge, if the processor is in NAP
mode the whole time while waiting for an SMU command to complete,
then the SMU will fail.  It could be related to the weird backward
mechanism the SMU uses to get to system memory via i2c to the
northbridge that doesn't operate properly when the said bridge is
in napping along with the CPU.  That is on U3 at least, U4 doesn't
seem to be affected.

This didn't show before NO_HZ as the timer wakeup was enough to make
it work it seems, but that is no longer the case.

This fixes it by disabling NAP mode on those machines while
an SMU command is in flight.

hrtimer: check relative timeouts for overflow

2008-02-26T00:14:07+00:00

commit: 5a7780e725d1bb4c3094fcc12f1c5c5faea1e988

Various user space callers ask for relative timeouts. While we fixed
that overflow issue in hrtimer_start(), the sites which convert
relative user space values to absolute timeouts themself were uncovered.

Instead of putting overflow checks into each place add a function
which does the sanity checking and convert all affected callers to use
it.

Thanks to Frans Pop, who reported the problem and tested the fixes.

m68k: Export cachectl.h

2008-02-08T20:01:43+00:00

patch e92042e5c009d84ba741ec4a978a13f260e6ee24 in mainline.

m68k: Export cachectl.h

libffi in GCC 4.2 needs cachectl.h to do its cache flushing.  But we
don't currently export it.  I believe this patch should do the trick.

Freezer: Fix APM emulation breakage

2008-02-08T20:01:33+00:00

The APM emulation is currently broken as a result of commit
831441862956fffa17b9801db37e6ea1650b0f69
"Freezer: make kernel threads nonfreezable by default"
that removed the PF_NOFREEZE annotations from apm_ioctl() without
adding the appropriate freezer hooks.  Fix it and remove the
unnecessary variable flags from apm_ioctl().

This problem has been fixed in the mainline by
commit cb43c54ca05c01533c45e4d3abfe8f99b7acf624
"Freezer: Fix APM emulation breakage".

PM: ACPI and APM must not be enabled at the same time

2008-02-08T20:01:32+00:00

patch 9f9adecd2d0e4f88fa0e8cb06c6ec207748df70a in mainline.

ACPI and APM used "pm_active" to guarantee that
they would not be simultaneously active.

But pm_active was recently moved under CONFIG_PM_LEGACY,
so that without CONFIG_PM_LEGACY, pm_active became a NOP --
allowing ACPI and APM to both be simultaneously enabled.
This caused unpredictable results, including boot hangs.

Further, the code under CONFIG_PM_LEGACY is scheduled
for removal.

So replace pm_active with pm_flags.
pm_flags depends only on CONFIG_PM,
which is present for both CONFIG_APM and CONFIG_ACPI.
