| | * | | thinkpad-acpi: fix incorrect use of TPACPI_BRGHT_MODE_ECNVRAMHenrique de Moraes Holschuh2009-08-011-14/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | HBRV-based default selection of backlight control strategy didn't work well, at least the X41 defines it but doesn't use it and I don't think it will stop there. Switch to a white/blacklist. All models that have HBRV defined have been included in the list, and initially all ATI GPUs will get ECNVRAM, and the Intel GPUs will get UCMS_STEP. Symptoms of incorrect backlight mode selection are: 1. Non-working backlight control through sysfs; 2. Backlight gets reset to the lowest level at every shutdown, reboot and when thinkpad-acpi gets unloaded; This fixes a regression in 2.6.30, bugzilla #13826 Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Reported-by: Tobias Diedrich <ranma+kernel@tdiedrich.de> Cc: stable@kernel.org Signed-off-by: Len Brown <len.brown@intel.com>

| | * | | thinkpad-acpi: remove dock and bay subdriversHenrique de Moraes Holschuh2009-08-013-481/+0

Userspace needs some love to support the two-stage ejection nicely, but it is simple enough to do through udev rules (you don't even need HAL) so this wouldn't justify fixing the dock and bay subdrivers, either. That leaves warm-swap bays (_EJ3) support for thinkpad-acpi, as well as support for the weird dock of the model 570, but since such support has never left the "experimental" stage, it is also not a strong enough reason to find a way to fix this code. Users of ThinkPads with warm-swap bays are urged to request that _EJ3 support be added to the regular ACPI dock driver, if such feature is indeed useful for them.

| | * | | thinkpad-acpi: disable broken bay and dock subdriversHenrique de Moraes Holschuh2009-08-011-1/+3

OTOH, the standard ACPI dock driver can handle the hotplug bays and docks of the ThinkPads just fine (including batteries) as of 2.6.27. In fact, it does a much better job of it than thinkpad-acpi ever did. It is just not worth the hassle to find a way to fix this crap without breaking the (deprecated) thinkpad-acpi dock/bay ABI. This is old, deprecated code that sees little testing or use. As a quick fix suitable for -stable backports, mark the thinkpad-acpi bay and dock subdrivers as BROKEN in Kconfig. The dead code will be removed by a later patch. This fixes bugzilla #13669, and should be applied to 2.6.27 and later.

* | | | Make pci_claim_resource() use request_resource() rather than insert_resource()Linus Torvalds2009-08-021-2/+2

So there Matthew fixed it to actually look up the proper parent resource, which means that now it's actively wrong to then traverse the resource tree any more: we already know exactly where the new resource should go. And when we then did commit a76117dfd6 ("x86: Use pci_claim_resource"), which changed the x86 PCI code from the open-coded pr = pci_find_parent_resource(dev, r); if (!pr || request_resource(pr, r) < 0) { to using if (pci_claim_resource(dev, idx) < 0) { that "insert_resource()" now suddenly became a problem, and causes a regression covered by http://bugzilla.kernel.org/show_bug.cgi?id=13891 which this fixes.

|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ulrich Drepper correctly points out that there is generally padding in the structure on 64-bit hosts, and that copying the structure from kernel to user space can leak information from the kernel stack in those padding bytes. Avoid the whole issue by just copying the three members one by one instead, which also means that the function also can avoid the need for a stack frame. This also happens to match how we copy the new structure from user space, so it all even makes sense.

Chop it down to something reasonable, the number of slots in the caller's input buffer. If this is too large the caller may get ENOMEM but the reason should not be a mystery, and they can try again with something smaller. We add 1 to the value because in the normal getbmap world, bmv_count includes the header and xfs_getbmap does: nex = bmv->bmv_count - 1; if (nex <= 0) return XFS_ERROR(EINVAL); Signed-off-by: Eric Sandeen <sandeen@sandeen.net> Reviewed-by: Olaf Weber <olaf@sgi.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Felix Blyakher <felixb@sgi.com>

This can be larger than what the page allocator can provide so it prints a warning. However, the caller is able to handle the situation so this patch suppresses the warning.
