2008-03-25KVM: MMU: Fix memory leak on guest demand faultsAvi Kivity
While backporting 72dc67a69690288538142df73a7e3ac66fea68dc, a gfn_to_page() call was duplicated instead of moved (due to an unrelated patch not being present in mainline). This caused a page reference leak, resulting in a fairly massive memory leak. Fix by removing the extraneous gfn_to_page() call. Signed-off-by: Avi Kivity <avi@qumranet.com>

2008-03-25KVM: VMX: Restore tss even on x86_64Avi Kivity
The vmx hardware state restore restores the tss selector and base address, but not its length. Usually, this does not matter since most of the tss contents is within the default length of 0x67. However, if a process is using ioperm() to grant itself I/O port permissions, an additional bitmap within the tss, but outside the default length is consulted. The effect is that the process will receive a SIGSEGV instead of transparently accessing the port. Fix by restoring the tss length. Note that i386 had this working already. Closes bugzilla 10246.

2008-03-24x86-32: Pass the full resource data to ioremap()Linus Torvalds
It appears that 64-bit PCI resources cannot possibly ever have worked on x86-32 even when the RESOURCES_64BIT config option was set, because any driver that tried to [pci_]ioremap() the resource would have been unable to do so because the high 32 bits would have been silently dropped on the floor by the ioremap() routines that only used "unsigned long". Change them to use "resource_size_t" instead, which properly encodes the whole 64-bit resource data if RESOURCES_64BIT is enabled. Acked-by: H.

2008-03-24[POWERPC] Fix Oops with TQM5200 on TQM5200Anatolij Gustschin
The "bestcomm-core" driver defines its of_match table as follows static struct of_device_id mpc52xx_bcom_of_match[] = { { .type = "dma-controller", .compatible = "fsl,mpc5200-bestcomm", }, { .type = "dma-controller", .compatible = "mpc5200-bestcomm", }, {}, }; so while registering the driver, the driver's probe function won't be called, because the device tree node doesn't have a device_type property. Thus the driver's bcom_engine structure won't be allocated. Referencing this structure later causes observed Oops. Checking bcom_eng pointer for NULL before referencing data pointed by it prevents oopsing, but fec driver still doesn't work (because of the lost bestcomm match and resulted task allocation failure). Actually the compatible property exists and should match and so the fec driver should work. This removes .type = "dma-controller" from the bestcomm driver's mpc52xx_bcom_of_match table to solve the problem.

2008-03-24[POWERPC] Don't use 64k pages for ioremap on pSeriesPaul Mackerras
On pSeries, the hypervisor doesn't let us map in the eHEA ethernet adapter using 64k pages, and thus the ehea driver will fail if 64k pages are configured. This works around the problem by always using 4k pages for ioremap on pSeries (but not on other platforms). A better fix would be to check whether the partition could ever have an eHEA adapter, and only force 4k pages if it could, but this will do for 2.6.25. This is based on an earlier patch by Tony Breeds. Signed-off-by: Paul Mackerras <paulus@samba.org>

2008-03-22x86: revert: reserve dma32 early for gartThomas Gleixner
Revert commit f62f1fc9ef94f74fda2b456d935ba2da69fa0a40 Author: Yinghai Lu <yhlu.kernel@gmail.com> Date: Fri Mar 7 15:02:50 2008 -0800 x86: reserve dma32 early for gart The patch has a dependency on bootmem modifications which are not .25 material that late in the -rc cycle. The problem which is addressed by the patch is limited to machines with 256G and more memory booted with NUMA disabled. This is not a .25 regression and the audience which is affected by this problem is very limited, so it's safer to do the revert than pulling in intrusive bootmem changes right now.

2008-03-21[SPARC64]: Remove most limitations to kernel image size.David S. Miller
Currently kernel images are limited to 8MB in size, and this causes problems especially when enabling features that take up a lot of kernel image space such as lockdep. The code now will align the kernel image size up to 4MB and map that many locked TLB entries. So, the only practical limitation is the number of available locked TLB entries which is 16 on Cheetah and 64 on pre-Cheetah sparc64 cpus. Niagara cpus don't actually have hw locked TLB entry support. Rather, the hypervisor transparently provides support for "locked" TLB entries since it runs with physical addressing and does the initial TLB miss processing. Fully utilizing this change requires some help from SILO, a patch for which will be submitted to the maintainer. Essentially, SILO will only currently map up to 8MB for the kernel image and that needs to be increased. Note that neither this patch nor the SILO bits will help with network booting. The openfirmware code will only map up to a certain amount of kernel image during a network boot and there isn't much we can to about that other than to implemented a layered network booting facility. Solaris has this, and calls it "wanboot" and we may implement something similar at some point. Signed-off-by: David S. Miller <davem@davemloft.net>

a0c1e9073ef7428a14309cba010633a6cd6719ea "futex: runtime enable pi and robust functionality" introduces a test wether futex in atomic stuff works or not. It does that by writing to address 0 of the kernel address space. This will crash on older machines where addressing mode switching is enabled but where the mvcos instruction is not available. Page table walking is done by hand and therefore the code tries to access current->mm which is NULL. Therefore add an extra check, so we survive the early test.

2008-03-20ARM: OMAP: Fix GPIO IRQ unmaskKevin Hilman
GPIO IRQ unmask doesn't actually do anything useful. The problem is hidden by a separate explicit mass unmask at the end of the chained bank handler. Signed-off-by: Kevin Hilman <khilman@mvista.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2008-03-20ARM: OMAP: Fix clockevent support for hrtimersKevin Hilman
One-shot mode was broken in MPU-timer support for OMAP1 due to a typo. Also, ensure timer is stopped before changing the auto-reload flag. The TRM says changing the AR flag when timer is running is undefined. Also set GENERIC_CLOCKEVENTS for all omaps.

2008-03-20[POWERPC] Hide resources on Axon PCIE root complex nodesMichael Ellerman
The PCI bridge representing the PCIE root complex on Axon, contains device BARs for a memory range and ROM that define inbound accesses. This confuses the kernel resource management code -- the resources need to be hidden when Axon is a host bridge.

2008-03-20[POWERPC] Fix cell IOMMU code to cope with empty dma-ranges and non-PCI devicesMichael Ellerman
The cell IOMMU code to parse the dma-ranges properties, used for the fixed mapping, was broken in two ways for some devices. Firstly it didn't cope with empty dma-ranges properties. An empty property implies no translation so can be safely skipped. The code also wrongly assumed it would be looking at PCI devices, and hard coded the number of address and size cells.
