2391dae Rafael J. Wysocki 01 July 2007, 19:07:33 UTC PM: introduce set_target method in pm_ops 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.

cbcdd77 Bjorn Helgaas 01 July 2007, 19:06:49 UTC smsc-ircc2: bypass PNP detection until we get the quirks worked out 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.

5ebffd7 Maxime Austruy 01 July 2007, 19:06:38 UTC asus_acpi: fix oops on non-asus machines 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.

4710bcc Linus Torvalds 01 July 2007, 17:56:11 UTC i386: remove bogus mtrr range check 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.

edd5cd4 David Woodhouse 27 June 2007, 21:10:09 UTC Introduce fixed sys_sync_file_range2() syscall, implement on PowerPC and ARM 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.

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.

59faba1 Trent Piepho 27 June 2007, 21:09:54 UTC Fix Kconfig dependency problems wrt boolean menuconfigs 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.

30acbab Hugh Dickins 27 June 2007, 21:09:53 UTC mm: kill validate_anon_vma to avoid mapcount BUG 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.

172d049 Bjorn Helgaas 27 June 2007, 21:09:52 UTC PNP SMCf010 quirk: auto-config device if BIOS left it broken 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.

7c31d2f Bjorn Helgaas 27 June 2007, 21:09:50 UTC smsc-ircc2: skip preconfiguration for PNP devices 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.

240e2df Michael Halcrow 27 June 2007, 21:09:44 UTC eCryptfs: fix write zeros behavior This patch fixes the processes involved in wiping regions of the data during truncate and write events, fixing a kernel hang in 2.6.22-rc4 while assuring that zero values are written out to the appropriate locations during events in which the i_size will change. The range passed to ecryptfs_truncate() from ecryptfs_prepare_write() includes the page that is the object of ecryptfs_prepare_write(). This leads to a kernel hang as read_cache_page() is executed on the same page in the ecryptfs_truncate() execution path. This patch remedies this by limiting the range passed to ecryptfs_truncate() so as to exclude the page that is the object of ecryptfs_prepare_write(); it also adds code to ecryptfs_prepare_write() to zero out the region of its own page when writing past the i_size position. This patch also modifies ecryptfs_truncate() so that when a file is truncated to a smaller size, eCryptfs will zero out the contents of the new last page from the new size through to the end of the last page.

48d8d7e Siddha, Suresh B 25 June 2007, 22:52:35 UTC x86_64 irq: use mask/unmask and proper locking in fixup_irqs() Force irq migration path during cpu offline, is not using proper locks and irq_chip mask/unmask routines. This will result in some races(especially the device generating the interrupt can see some inconsistent state, resulting in issues like stuck irq,..). Appended patch fixes the issue by taking proper lock and encapsulating irq_chip set_affinity() with a mask() before and an unmask() after. This fixes a MSI irq stuck issue reported by Darrick Wong. There are several more general bugs in this area(irq migration in the process context). For example, 1. Possibility of missing edge triggered irq. 2. Reliable method of migrating level triggered irq in the process context. We plan to look and close these in the near future. Eric says: In addition even with the fix from Suresh there is still at least one nasty hardware race in fixup_irqs(). However we exercise that code path rarely enough that we are unlikely to hit it in the real world, and that race seems to have existed since the code was merged. And a fix for that is not coming soon as it is an open investigation area if we can fix irq migration to work outside of irq context or if we have to rework the requirements imposed by the generic cpu hotplug and layer on fixup_irqs(). So this may come up again. Signed-off-by: Suresh Siddha <suresh.b.siddha@intel.com> Cc: Eric W.

1ee27a4 Jes Sorensen 18 June 2007, 15:19:05 UTC [IA64] Make SN2 PCI code use ioremap rather than manually mangle the address This one changes the SN2 specific PCI drivers to use ioremap() for obtaining the real address to access for the PCI registers instead of manually calculating them with __IA64_UNCACHED_OFFSET. The patch should have no real change when running on a normal Linux kernel, but when running as a paravirtualized it is needed.

ae62fbb Paul Mackerras 26 June 2007, 04:49:11 UTC [POWERPC] Fix subtle FP state corruption bug in signal return on SMP This fixes a bug which can cause corruption of the floating-point state on return from a signal handler. If we have a signal handler that has used the floating-point registers, and it happens to context-switch to another task while copying the interrupted floating-point state from the user stack into the thread struct (e.g. because of a page fault, or because it gets preempted), the context switch code will think that the FP registers contain valid FP state that needs to be copied into the thread_struct, and will thus overwrite the values that the signal return code has put into the thread_struct. This can occur because we clear the MSR bits that indicate the presence of valid FP state after copying the state into the thread_struct. To fix this we just move the clearing of the MSR bits to before the copy. A similar potential problem also occurs with the Altivec state, and this fixes that in the same way.
