The following patch (based on a patch from Stephen Gildea) fixes a regression with the LCD brightness keys on Fujitsu P8010 laptops which was observed with the 2.6.27-rc series (basically they stopped working due to changes within the fujitsu-laptop and video modules). Please apply to 2.6.27-rc and acpi git. A more complete solution for this laptop will be included in an upcoming patch, hopefully for 2.6.28. In the meantime this restores most functionality for P8010 users.

Commit 88452565 ("PCI: clean up resource alignment management") changed the resource handling to mark how a resource was aligned on a per-resource basis. Thus, instead of looking at the resource number to determine whether it was a bridge resource or a regular resource (they have different alignment rules), we should just ask the resource for its alignment directly. The reason this broke only cardbus resources was that for the other types of resources, the old way of deciding alignment actually still happened to work. But CardBus bridge resources had been changed by commit 934b7024 ("Fix cardbus resource allocation") to look more like regular resources than PCI bridge resources from an alignment handling standpoint.

When calibration against PIT fails, the warning that we print is misleading. In a virtualized environment the VM may get descheduled while calibration or, the check in PIT calibration may fail due to other virtualization overheads. The warning message explicitly assumes that calibration failed due to SMI's which may not be the case. Change that to something proper.

Fix a bug and a philosophical decision about who handles errors. security_context_to_sid_core() was leaking a context in the common case. This was causing problems on fedora systems which recently have started making extensive use of this function. In discussion it was decided that if string_to_context_struct() had an error it was its own responsibility to clean up any mess it created along the way.

The allocated RX buffer size was 64 bytes bigger than the PCI mapped size with no good reason. If the packet was actually using the buffer up to its limit and if the last 64 bytes of the buffer crossed 4KB boundary then an unmapped PCI page was accessed. The fix is to use only one parameter for the buffer size - there is no need to differentiate between the buffer size and the PCI mapping size since the extra 64 bytes can actually be used by the FW to align the Ethernet payload to 64 bytes.

This patch "iwlwifi: do not use GFP_DMA in iwl_tx_queue_init" removes GFP_DMA from allocation tx command buffers. GFP_DMA allows allocation only for memory under 16M which causes allocation problems suspend/resume flows. Using kmalloc is temporal solution and some consistent/coherent allocation schema will be more correct. Since iwlwifi hardware supports 64bit address this solution should work on x86 (32 and 64bit) for now. This patch fixes memory freeing problem in the previous patch.

This patch is a W/A for the TSF sync issue in IBSS merging. HW is not capable to sync TSF (it's constantly little behind). This creates constant IBSS merging upon reception of each beacon, adding and removing station which in turn creates above 50% packet loss and thus dramatically degrade the throughput. The W/A simply stops the driver from declaring it has a reliable TSF value and thus eliminates IBSS merging.

This bug is causing random crashes (http://bugzilla.kernel.org/show_bug.cgi?id=11414). -fno-omit-frame-pointer is only needed on powerpc when -pg is also supplied, and there is a gcc bug that causes incorrect code generation on 32-bit powerpc when -fno-omit-frame-pointer is used---it uses stack locations below the stack pointer, which is not allowed by the ABI because those locations can and sometimes do get corrupted by an interrupt. This ensures that CONFIG_FRAME_POINTER is only selected by ftrace. When CONFIG_FTRACE is enabled we also pass -mno-sched-epilog to work around the gcc codegen bug.

Commit bc033b63 ("powerpc/mm: Fix attribute confusion with htab_bolt_mapping()") moved the check for whether we should make pages of the linear mapping executable from htab_bolt_mapping into its callers, including htab_initialize. A side-effect of this is that the decision is now made once for each contiguous section in the LMB array rather than for each page individually. This can often mean that the whole of the linear mapping ends up being executable. This reverts to the previous behaviour, where individual pages are checked for being part of the kernel text or not, by moving the check back down into htab_bolt_mapping.
