* [PATCH] ACPI: fix sleeping whilst atomic warnings on resumeDave Jones2005-12-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | This has been broken for months. On resume, we call acpi_pci_link_set() with interrupts off, so we get a warning when we try to do a kmalloc of non atomic memory. The actual allocation is just 2 long's (plus extra byte for some reason I can't fathom), so a simple conversion to GFP_ATOMIC is probably the safest way to fix this. The error looks like this.. Debug: sleeping function called from invalid context at mm/slab.c:2486 in_atomic():0, irqs_disabled():1 [<c0143f6c>] kmem_cache_alloc+0x40/0x56 [<c0206a2e>] acpi_pci_link_set+0x3f/0x17f [<c0206f96>] irqrouter_resume+0x1e/0x3c [<c0239bca>] __sysdev_resume+0x11/0x6b [<c0239e88>] sysdev_resume+0x34/0x52 [<c023de21>] device_power_up+0x5/0xa Signed-off-by: Dave Jones <davej@redhat.com> Cc: "Brown, Len" <len.brown@intel.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| * [ACPI] PCI interrupt link suspend/resume - revert to 2.6.12 behaviourDavid Shaohua Li2005-08-031-0/+11
| | | | | | | | | | | | | | | | | | | | This patch disables the PCI Interrupt Link refernece counts, which should not co-exist with the 2.6.12 irq_router.resume method or else a double acpi_pci_link_set() could result on resume.

* | Revert ACPI interrupt resume changesLinus Torvalds2005-08-011-20/+18
|/ | | | | | | | | If there are devices that use interrupts over a suspend event, ACPI must restore the PCI interrupt links on resume. Anything else breaks any device that hasn't been converted to the new (dubious) PM rules. Drivers that need the irq free/re-aquire sequence can be done one by one independently of this one.

| | | | | | | | | | | | | | | Delete PCI Interrupt Link Device .resume method -- it is the device driver's job to request interrupts, not the Link's job to remember what the devices want. This addresses the issue of attempting to run the ACPI interpreter too early in resume, when interrupts are still disabled. http://bugzilla.kernel.org/show_bug.cgi?id=3469 Signed-off-by: David Shaohua Li <shaohua.li@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
