2009-03-25Revert "x86: don't compile vsmp_64 for 32bit"Ravikiran G Thirumalai
Partial revert of commit 129d8bc828e011bda0b7110a097bf3a0167f966e titled 'x86: don't compile vsmp_64 for 32bit' Commit reverted to compile vsmp_64.c if CONFIG_X86_64 is defined, since is_vsmp_box() needs to indicate that TSCs are not synchronized, and hence, not a valid time source, even when CONFIG_X86_VSMP is not defined.

2009-03-25x86: Correct behaviour of irq affinityRusty Russell
Impact: get correct smp_affinity as user requested The effect of setting desc->affinity (ie. from userspace via sysfs) has varied over time. In 2.6.27, the 32-bit code anded the value with cpu_online_map, and both 32 and 64-bit did that anding whenever a cpu was unplugged. 2.6.29 consolidated this into one routine (and fixed hotplug) but introduced another variation: anding the affinity with cfg->domain. We should just set it to what the user said - if possible. (cpu_mask_to_apicid_and already takes cpu_online_mask into account) Signed-off-by: Yinghai Lu <yinghai@kernel.org> Acked-by: "Eric W.

2009-03-24x86, PAT, PCI: Change vma prot in pci_mmap to reflect inherited protPallipadi, Venkatesh
While looking at the issue in the thread: http://marc.info/?l=dri-devel&m=123606627824556&w=2 noticed a bug in pci PAT code and memory type setting. PCI mmap code did not set the proper protection in vma, when it inherited protection in reserve_memtype. This bug only affects the case where there exists a WC mapping before X does an mmap with /proc or /sys pci interface. This will cause X userlevel mmap from /proc or /sysfs to fail on fork.

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.

This reverts commit 698609bdcd35d0641f4c6622c83680ab1a6d67cb. 69860 breaks Xen booting, as it relies on head*.S to set up the fixmap pagetables (as a side-effect of initializing the USB debug port). Xen, however, does not boot via head*.S, and so the fixmap area is not initialized. The specific symptom of the crash is a fault in dmi_scan(), because the pointer that early_ioremap returns is not actually present.

2009-03-20x86: fix IO APIC resource allocation error messageBartlomiej Zolnierkiewicz
Impact: fix incorrect error message - IO APIC resource allocation error message contains one too many "be". - Print the error message iff there are IO APICs in the system.
