Commit 52ade9b3b97fd3bea42842a056fe0786c28d0555 changed the suspend code
ordering to execute pm_ops->prepare() after the device model per-device
.suspend() calls in order to fix some ACPI-related issues. Unfortunately, it
broke the at91 platform which assumed that pm_ops->prepare() would be called
before suspending devices.at91 used pm_ops->prepare() to get notified of the target system sleep state,
so that it could use this information while suspending devices. However, with
the current suspend code ordering pm_ops->prepare() is called too late for
this purpose. Thus, at91 needs an additional method in 'struct pm_ops' that
will be used for notifying the platform of the target system sleep state.
Moreover, in the future such a method will also be needed by ACPI.This patch adds the .set_target() method to 'struct pm_ops' and makes the
suspend code call it, if implemented, before executing the device model
per-device .suspend() calls. It also modifies the at91 code to use
pm_ops->set_target() instead of pm_ops->prepare().Signed-off-by: Rafael J. Wysocki

Don't use PNP detection by default yet. We have some PNP and BIOS issues
to work out first.Sample problem on a Toshiba Portege 4000: the SMCf010 device is handed off
disabled. We assign I/O ports originally assigned to the SMCf010 to a
PCMCIA device instead. We enable the SMCf010, configuring it to use
disjoint ports, but _SRS doesn't work correctly, so the device doesn't
work.Signed-off-by: Bjorn Helgaas

If asus_acpi_init doesn't find any device it knows about, it mistakenly
returns a "success" error code even though it cleans up after itself. Later
when trying to rmmod asus_acpi, the module_exit routine would try to clean up
one more time and we would end up calling
acpi_bus_unregister_driver(&asus_hotk_driver) twice. This patch addresses
this first problem by returning -ENODEV when no appropriate device is found.Then there was also another bug with the code handling the return value of
backlight_device_register. If this function ever failed, the driver would
cleanup by calling the module_exit routine from module_init, but it would
still return "success". So any attempt to rmmod this module would result in
asus_acpi_exit being called twice but it's not ready to handle it (I haven't
hit this bug, just found it by code inspection). This patch fixes that by
inserting a return -ENODEV; at the end of this error handling path.Signed-off-by: Maxime Austruy

Commit 9215da33209b861b01c51382254b178a3fe92a30 "fixed" the MTRR range
check to not allow any MTRR's under the 1MB mark (since that's where the
fixed MTRR's are active).However, that was totally bogus, since it's normal (and almost required)
to have a large variable MTRR that starts at 0, and covers some large
percentage of the whole RAM, and then using the fixed MTRR's to override
that large MTRR to handle the special ISA hole in the 640k-1M region.The old check was bogus too (checking that no variable MTRR is used that
is entirely under the 1MB range), but at least it wasn't actively
detrimental, because no sane situation would ever trigger such MTRR
usage in the first place.That said, the whole notion of not allowing variable MTRR's in the low
1MB is just stupid, so rather than revert the commit, this just removes
the whole sad and unnecessary check entirely.Cc: Jan Beulich

fixing problems with NULL gettimeofday input mistakenly checks for a
null tz field twice, when it should be checking for null tz once, and
null tv once; by way of a r10/r11 typo.Any application calling gettimeofday(&tv,NULL) will "fail".
This corrects that typo, and makes my G5 happy.

#1
Until kernel ver. 2.6.21 (including) cancel_rearming_delayed_work()
required a work function should always (unconditionally) rearm with
delay > 0 - otherwise it would endlessly loop. This patch replaces
this function with cancel_delayed_work(). Later kernel versions don't
require this, so here it's only for uniformity.#2

phy: Fix phy_id for Vitesse 824x PHY -
Not all the world is an i386. Many architectures need 64-bit arguments to be
aligned in suitable pairs of registers, and the original
sys_sync_file_range(int, loff_t, loff_t, int) was therefore wasting an
argument register for padding after the first integer. Since we don't
normally have more than 6 arguments for system calls, that left no room for
the final argument on some architectures.Fix this by introducing sys_sync_file_range2(int, int, loff_t, loff_t) which
all fits nicely. In fact, ARM already had that, but called it
sys_arm_sync_file_range. Move it to fs/sync.c and rename it, then implement
the needed compatibility routine. And stop the missing syscall check from
bitching about the absence of sys_sync_file_range() if we've implemented
sys_sync_file_range2() instead.Tested on PPC32 and with 32-bit and 64-bit userspace on PPC64.

This patch changes the test for the thread pid from >= 0 to > 0.
When the saa8134 driver initialization fails after a certain point, it goes
through the complete shutdown process for the driver. Part of shutting it
down includes tearing down the thread for tv audio.The test for tearing down the thread tests for >= 0. Since the dev
structure is kzalloc'd, the test will always be true if we haven't tried to
start the thread yet. We end up waiting on pid 0 to complete, which will
never happen, so we lock up.This bug was observed in Novell Bugzilla 284718, when request_irq() failed.

If one has a dependency chain (tristate)FOO depends on (bool)BAR depends on
(tristate)BAZ, build problems will result. If BAZ=m, then BAR can be set
y, which allows FOO=y. It's possible to have FOO=y && BAZ=m, which
wouldn't be allowed if FOO depended directly on BAZ. In effect, the bool
promotes the tristate from m to y.This ends up causing a problem with several menuconfigs that look like:
menuconfig BAR
bool
depends on BAZ [tristate]
if BAR
config FOO
tristate
endifThe solution used here is to add the dependencies of BAR to the if
statement, so that items in the if block will gain a direct
non-bool-promoted dependency on BAZ. This is how it would work if a menu
was used instead of an if block.Signed-off-by: Trent Piepho

validate_anon_vma gave a useful check on the integrity of the anon_vma list
when Andrea was developing obj rmap; but it was not enabled in SLES9
itself, nor in mainline, until Nick changed commented-out RMAP_DEBUG to
configurable CONFIG_DEBUG_VM in 2.6.17. Now Petr Vandrovec reports that
its BUG_ON(mapcount > 100000) can easily crash a CONFIG_DEBUG_VM=y system.That limit was just an arbitrary number to protect against an infinite
loop. We could raise it to something enormous (depending on sizeof struct
vma and size of memory?); but I rather think validate_anon_vma has outlived
its usefulness, and is better just removed - which gives a magnificent
performance boost to anything like Petr's test program ;)Of course, a very long anon_vma list is bad news for preemption latency,
and I believe there has been one recent report of such: let's not forget
that, but validate_anon_vma only makes it worse not better.Signed-off-by: Hugh Dickins

Some HP firmware leaves the SMCf010 IRDA device incompletely configured, or
reports the wrong resources in _CRS. As a workaround, when we find such a
device, try to auto-configure the device.This ignores the _CRS data, picks a config from _PRS, and runs _SRS to
configure the device. This makes smsc-ircc2 work correctly with PNP
resources (with no preconfiguration!) on all the machines I tested.I think Windows does something like this by default for all devices,
so we should consider doing the same thing in Linux.This patch addresses part of the 2.6.22 regression:
"no irda0 interface (2.6.21 was OK), smsc does not find chip"
It fixes smsc-ircc2 PNP device detection on HP nc6000, nc6220, nw8000,

If we rely on the device resources from PNPBIOS, we also have to rely on
the BIOS to configure any bridges on the way to the device.Using the PNPBIOS resources but changing the configuration of a bridge
behind the back of the firmware is likely to make things inconsistent.This patch addresses part of the 2.6.22 regression:
"no irda0 interface (2.6.21 was OK), smsc does not find chip"
It fixes smsc-ircc2 PNP device detection on HP nx5000 laptops.
Other laptops, including HP nc6000, HP nc8000, HP nw8000, and Toshiba
Portege 4000, still need PNP quirks to make this work.With "smsc-ircc2.nopnp", we do the legacy device probe, including manual
bridge preconfiguration, as before.Signed-off-by: Bjorn Helgaas
