2009-03-24powerpc/mm: Add option for non-atomic PTE updates to ppc64Benjamin Herrenschmidt
ppc32 has it already, add it to ppc64 as a preliminary for adding support for Book3E 64-bit support Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

2009-03-24powerpc/mm: Rename arch/powerpc/kernel/mmap.c to mmap_64.cBenjamin Herrenschmidt

2009-03-24powerpc/mm: Merge various PTE bits and accessors definitionsBenjamin Herrenschmidt
Now that they are almost identical, we can merge some of the definitions related to the PTE format into common files. This creates a new pte-common.h which is included by both 32 and 64-bit right after the CPU specific pte-*.h file, and which defines some bits to "default" values if they haven't been defined already, and then provides a generic definition of most of the bit combinations based on these and exposed to the rest of the kernel. I also moved to the common pgtable.h most of the "small" accessors to the PTE bits and modification helpers (pte_mk*). The actual accessors remain in their separate files.

2009-03-24powerpc/mm: Tweak PTE bit combination definitionsBenjamin Herrenschmidt
This patch tweaks the way some PTE bit combinations are defined, in such a way that the 32 and 64-bit variant become almost identical and that will make it easier to bring in a new common pte-* file for the new variant of the Book3-E support. The combination of bits defining access to kernel pages are now clearly separated from the combination used by userspace and the core VM. The resulting generated code should remain identical unless I made a mistake. Note: While at it, I removed a non-sensical statement related to CONFIG_KGDB in ppc_mmu_32.c which could cause kernel mappings to be user accessible when that option is enabled. Probably something that bitrot. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

2009-03-24powerpc/mm: e300c2/c3/c4 TLB errata workaroundKumar Gala
Complete workaround for DTLB errata in e300c2/c3/c4 processors. Due to the bug, the hardware-implemented LRU algorythm always goes to way 1 of the TLB.

2009-03-24powerpc: expect all devices calling dma ops to have archdata setKumar Gala

2009-03-24powerpc: setup default archdata for {of_}platform via bus_register_notifierKumar Gala
Since a number of powerpc chips are SoCs we end up having dma-able devices that are registered as platform or of_platform devices. We need to hook the archdata to setup proper dma_ops for these devices. Rather than having to add a bus_notify to each platform we add a default one at the highest priority (called first) to set the default dma_ops for of_platform and platform devices to dma_direct_ops. This allows platform code to override the ops by providing their own notifier call back. In the future to enable >4G DMA support on ppc32 we can hook swiotlb ops.

With a sufficiently new compiler and binutils, code which wasn't previously generating .eh_frame sections has begun to. Certain architectures (powerpc, in this case) may generate unexpected relocation formats in response to this, preventing modules from loading. While the new relocation types should probably be handled, revert to the previous behaviour with regards to generation of .eh_frame sections.

2009-03-23fix ptrace slownessMiklos Szeredi
This patch fixes bug #12208: Bug-Entry : http://bugzilla.kernel.org/show_bug.cgi?id=12208 Subject : uml is very slow on 2.6.28 host This turned out to be not a scheduler regression, but an already existing problem in ptrace being triggered by subtle scheduler changes. The problem is this: - task A is ptracing task B - task B stops on a trace event - task A is woken up and preempts task B - task A calls ptrace on task B, which does ptrace_check_attach() - this calls wait_task_inactive(), which sees that task B is still on the runq - task A goes to sleep for a jiffy - ... Since UML does lots of the above sequences, those jiffies quickly add up to make it slow as hell. This patch solves this by not rescheduling in read_unlock() after ptrace_stop() has woken up the tracer. Thanks to Oleg Nesterov and Ingo Molnar for the feedback.

Also, since we fully construct phy_bus_id in the _probe() routine, we no longer need ->phy_address and ->mdio_bus fields in ucc_geth_info structure. I wish the patch would be a bit shorter, but it seems like the only way to fix the issue in a sane way. Luckily, the patch has been tested with real PHYs and fixed-link, so no further regressions expected.

2009-03-22dm9000: locking bugfixDavid Brownell
This fixes a locking bug in the dm9000 driver. It calls request_irq() without setting IRQF_DISABLED ... which is correct for handlers that support IRQ sharing, since that behavior is not guaranteed for shared IRQs. However, its IRQ handler then wrongly assumes that IRQs are blocked. So the fix just uses the right spinlock primitives in the IRQ handler. NOTE: this is a classic example of the type of bug which lockdep currently masks by forcibly setting IRQF_DISABLED on IRQ handlers that did not request that flag.

2009-03-22eCryptfs: Allocate a variable number of pages for file headersTyler Hicks
When allocating the memory used to store the eCryptfs header contents, a single, zeroed page was being allocated with get_zeroed_page(). However, the size of an eCryptfs header is either PAGE_CACHE_SIZE or ECRYPTFS_MINIMUM_HEADER_EXTENT_SIZE (8192), whichever is larger, and is stored in the file's private_data->crypt_stat->num_header_bytes_at_front field. ecryptfs_write_metadata_to_contents() was using num_header_bytes_at_front to decide how many bytes should be written to the lower filesystem for the file header. Unfortunately, at least 8K was being written from the page, despite the chance of the single, zeroed page being smaller than 8K. This resulted in random areas of kernel memory being written between the 0x1000 and 0x1FFF bytes offsets in the eCryptfs file headers if PAGE_SIZE was 4K. This patch allocates a variable number of pages, calculated with num_header_bytes_at_front, and passes the number of allocated pages along to ecryptfs_write_metadata_to_contents(). Thanks to Florian Streibelt for reporting the data leak and working with me to find the problem. 2.6.28 is the only kernel release with this vulnerability.

2009-03-22radeonfb: Whack the PCI PM register until it sticksBenjamin Herrenschmidt
This fixes a regression introduced when we switched to using the core pci_set_power_state(). The chip seems to need the state to be written over and over again until it sticks, so we do that. Note that the code is a bit blunt, without timeout, etc... but that's pretty much because I put back in there the code exactly as it used to be before the regression. I still add a call to pci_set_power_state() at the end so that ACPI gets called appropriately on x86.
