2008-05-19PCI: Correct last two HP entries in the bfsort whitelistTony Camuso
Replace Redundant Whitelist Entries with the Correct Ones The ProLiant DL585 G2 and the DL585 G2 are entered reundantly in the dmi_system_id table. What should have been there are the DL360 and DL380. This patch simply replaces the redundant entries with the correct entries.

2008-05-19[POWERPC] 4xx: Workaround for CHIP_11 ErrataJosh Boyer
The PowerPC 440EP, 440GR, 440EPx, and 440GRx chips have an issue that causes the PLB3-to-PLB4 bridge to wait indefinitely for transaction requests that cross the end-of-memory-range boundary. Since the DDR controller only returns the valid portion of a read request, the bridge will prevent other PLB masters from completing their transactions. This implements the recommended workaround for this errata for chips that use older versions of firmware that do not already handle it. The last 4KiB of memory are hidden from the kernel to prevent the problem transactions from occurring.

2008-05-19sh: Fix up restorer in debug_trap exception return path.Paul Mundt
There are a few different types of debug trap exceptions, though now that they are all going through a special jump table, the restorer needs to be unified as well. Presently this is falling through the ret_from_fork path, which more or less does the right thing on SH-3/4 whilst being completely unsuitable on MMU-less targets. Ultimately what we want here is a branch through the platform's restore_all directly, without worrying about the retval being clobbered. We can accomplish that through a branch to __restore_all directly, so switch it so we come back from the jump table and branch to the restorer. This fixes up a recursion in the nommu WARN_ON() path, as well as some other userspace nastiness where said recursion caused serious stack corruption. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-05-19sh: Make is_valid_bugaddr() more intelligent on nommu.Paul Mundt
Currently is_valid_bugaddr() is true for anything >= PAGE_OFFSET, which happens to be 0 on nommu configurations. Make this a bit smarter by just reading in the opcode and comparing it against the trap type that we already know. Follows the logic from avr32. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-05-17[ARM] 5037/1: Orion: fix DNS323/Kurobox Pro PCI initialisationLennert Buytenhek
Whereas most Orion 5x machine support code would initialise the PCI subsystem with nr_controllers in their struct hw_pci set to 2, the DNS323 and Kurobox Pro machine support code had nr_controllers set to 1. This was presumably done because on those two machines, the PCI(-X) controller (nr == 1) isn't used, requiring initialisation of only the PCIe controller (nr == 0.) However, not initialising the PCI(-X) controller on boards that don't use it leads to a situation where both the PCIe and the PCI(-X) controller think that their root bus is zero, and it messes up IRQ assignment. This patch changes the DNS323 and Kurobox Pro support code to always use nr_controllers == 2.

2008-05-17[ARM] 5034/1: fix arm{925,926,940,946} dma_flush_range() in WT modeLennert Buytenhek
The CPU's dma_flush_range() operation needs to clean+invalidate the given memory area if the cache is in writeback mode, or do just the invalidate part if the cache is in writethrough mode, but the current proc-arm{925,926,940,946} (incorrectly) do a cache clean in the latter case.

2008-05-17x86: disable mwait for AMD family 10H/11H CPUsThomas Gleixner
The previous revert of 0c07ee38c9d4eb081758f5ad14bbffa7197e1aec left out the mwait disable condition for AMD family 10H/11H CPUs. Andreas Herrman said: It depends on the CPU. For AMD CPUs that support MWAIT this is wrong. Family 0x10 and 0x11 CPUs will enter C1 on HLT. Powersavings then depend on a clock divisor and current Pstate of the core. If all cores of a processor are in halt state (C1) the processor can enter the C1E (C1 enhanced) state. If mwait is used this will never happen. Thus HLT saves more power than MWAIT here. It might be best to switch off the mwait flag for these AMD CPU families like it was introduced with commit f039b754714a422959027cb18bb33760eb8153f0 (x86: Don't use MWAIT on AMD Family 10) Re-add the AMD families 10H/11H check and disable the mwait usage for those.

2008-05-17x86: fix crash on cpu hotplug on pat-incapable machinesAvi Kivity
