Commit 52ade9b3 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:

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:

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:

Commit 9215da33 "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.

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. Signed-off-by:

The interrupt clearing code in mpsc_sdma_intr_ack() mistakenly clears the interrupt for both controllers instead of just the one its supposed to. This can result in the other controller appearing to hang because its interrupt was effectively lost. So, don't clear the interrupt cause bits for both MPSC controllers when clearing the interrupt for one of them. Just clear the one that is supposed to be cleared. Signed-off-by:

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.

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 endif The 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:

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.

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, nw8240, and possibly other machines.

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.
