| * x86/agp: Fix agp_amd64_init() initialization with CONFIG_GART_IOMMU enabledFUJITA Tomonori2009-12-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | with CONFIG_GART_IOMMU enabled drivers/char/agp/amd64-agp.c has: #ifndef CONFIG_GART_IOMMU module_init(agp_amd64_init); module_exit(agp_amd64_cleanup); #endif agp_amd64_init() was called via gart_iommu_init with CONFIG_GART_IOMMU=y agp_amd64_init() was called via module_init with CONFIG_GART_IOMMU=n The commit 75f1cdf1dda92cae037ec848ae63690d91913eac changes the x86 dma initialization routine: gart_iommu_init() is called only when GART IOMMU is detected. So when GART IOMMU isn't detected, agp_amd64_init isn't called. Marin Mitov reported this issue: http://marc.info/?l=linux-kernel&m=126192729110083&w=2 With this patch, agp_amd64_init() is always called via module_init (the above ifndef is removed). If agp_amd64_init() is called via gart_iommu_init() earlier, agp_amd64_init() finishes without doing anything (when it is called via module_init).

| * x86: SGI UV: Fix writes to led registers on remote uv hubsMike Travis2009-12-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The wrong address was being used to write the SCIR led regs on remote hubs. Also, there was an inconsistency between how BIOS and the kernel indexed these regs. Standardize on using the lower 6 bits of the APIC ID as the index. This patch fixes the problem of writing to an errant address to a cpu # >= 64.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The assumption that acpi_table_parse passes the return value of the hanlder function to the caller proved wrong recently. The return value of the handler function is totally ignored. This makes the initialization code for AMD IOMMU buggy in a way that could cause a kernel panic on initialization. This patch fixes the issue in the AMD IOMMU driver. Cc: stable@kernel.org Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>

If dma debugging is disabled, this patch both prevents dma_debug_device_change notifiers from being added to the chain, and additionally ensures that the dma_debug_device_change notifier function is a no-op.

| * | x86, compress: Force i386 instructions for the decompressorH. Peter Anvin2009-12-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recently, some distros have started shipping versions of gcc which default to -march=i686. This breaks building kernels for pre-i686 machines, even if they have been selected in Kconfig, due to the generation of CMOV instructions. There isn't enough benefit to try to preserve the generation of these instructions even when selected, so simply force -march=i386 for the decompressor when building a 32-bit kernel.

On resume calling disable_irq_wake() will warn about unbalanced IRQ wake disable. Solve this by checking whether enable_irq_wake() succeeded or not and no not call disable_irq_wake() for these GPIOs/IRQs that have not been enabled.

Having 'gain' being unsigned int was an unfortunate choice since it dominates all implicit type conversions causing everything to be treated as unsigned int. Let's change it back to signed int and simply add proper casts to rumble effect calculations.

Now that they are separated and we don't risk resuming during 'thaw' we don't need to freeze kseriod anymore. This will allow us to start resetting mouse and keyboard a bit earlier, before rest of the userspace comes back up. Acked-by: Rafael J.
