* IOATDMA: fix section mismatchesRandy Dunlap2007-06-281-4/+4
| | | | | | | | | | | | | | | | | | | | Rename struct pci_driver data so that false section mismatch warnings won't be produced. Sam, ISTM that depending on variable names is the weakest & worst part of modpost section checking. Should __init_refok work here? I got build errors when I tried to use it, probably because the struct pci_driver probe and remove methods are not marked "__init_refok".

* Fix Kconfig dependency problems wrt boolean menuconfigsTrent Piepho2007-06-285-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Trent Piepho <xyzzy@speakeasy.org> Acked-by: Mauro Carvalho Chehab <mchehab@infradead.org> Cc: "David S.

* mm: kill validate_anon_vma to avoid mapcount BUGHugh Dickins2007-06-281-23/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* PNP SMCf010 quirk: auto-config device if BIOS left it brokenBjorn Helgaas2007-06-281-18/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* smsc-ircc2: skip preconfiguration for PNP devicesBjorn Helgaas2007-06-281-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* eCryptfs: fix write zeros behaviorMichael Halcrow2007-06-283-24/+50
| | | | | | | | | | | | | | | | | | | | | | | 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.

* | x86_64 irq: use mask/unmask and proper locking in fixup_irqs()Siddha, Suresh B2007-06-261-3/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the kernel release and version information to the output of show_regs/oops. Add the CPU PSR register. Avoid using printk to output partial lines; always output a complete line. Re-combine the "Control" and "Table + DAC" lines after nommu separated them; we don't want to waste vertical screen space needlessly. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
