2008-05-18i2c: Kill the old driver matching schemeJean Delvare
Remove the old driver_name/type scheme for i2c driver matching. Only the standard aliasing model will be used from now on. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2008-05-18i2c: Convert remaining new-style drivers to use module aliasingJean Delvare
Update all the remaining new-style i2c drivers to use standard module aliasing instead of the old driver_name/type driver matching scheme. Note that the tuner driver is a bit quirky at the moment, as it overwrites i2c_client.name with arbitrary strings. We write "tuner" back on remove, to make sure that driver cycling will work properly, but there may still be troublesome corner cases. Signed-off-by: Jean Delvare <khali@linux-fr.org>

2008-05-18i2c-nforce2: Disable the second SMBus channel on the DFI Lanparty NF4 ExpertJean Delvare
There is a strange chip at 0x2e on the second SMBus channel of the DFI Lanparty NF4 Expert motherboard. Accessing the chip reboots the system. As there's nothing interesting on this SMBus channel, the easiest and safest thing to do is to disable it on that board. This is a better fix to bug #5889 than the it87 driver update that was done originally: http://bugzilla.kernel.org/show_bug.cgi?id=5889 Signed-off-by: Jean Delvare <khali@linux-fr.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

2008-05-15initcalls: Fix m68k build and possible buffer overflowCyrill Gorcunov
This patch fixes a build bug on m68k - gcc decides to emit a call to the strlen library function, which we don't implement. More importantly - my previous patch "init: don't lose initcall return values" (commit e662e1cfd434aa234b72fbc781f1d70211cb785b) had introduced potential buffer overflow by wrong calculation of string accumulator size. Use strlcat() instead, fixing both bugs. Many thanks Andreas Schwab and Geert Uytterhoeven for helping to catch and fix the bug.

2008-05-15[IA64] fix personality(PER_LINUX32) performance issueHuang, Xiaolan
The patch aims to fix a performance issue for the syscall personality(PER_LINUX32). On IA-64 box, the syscall personality (PER_LINUX32) has poor performance because it failed to find the Linux/x86 execution domain. Then it tried to load the kernel module however it failed always and it used the default execution domain PER_LINUX instead. Requesting kernel modules is very expensive. It caused the performance issue. (see the function lookup_exec_domain in kernel/exec_domain.c). To resolve the issue, execution domain Linux/x86 is always registered in initialization time for IA-64 architecture.
