2010-04-27cxgb3: Wait longer for control packets on initializationAndre Detsch
In some Power7 platforms, when using VIOS (Virtual I/O Server), we need to wait longer for control packets to finish transfer during initialization. Without this change, initialization may fail prematurely.

2010-04-27e1000e: enable/disable ASPM L0s and L1 and ERT according to hardware errataBruce Allan
Prompted by a previous patch submitted by Matthew Garret <mjg@redhat.com>, further digging into errata documentation reveals the current enabling or disabling of ASPM L0s and L1 states for certain parts supported by this driver are incorrect. 82571 and 82572 should always disable L1. For standard frames, 82573/82574/82583 can enable L1 but L0s must be disabled, and for jumbo frames 82573/82574 must disable L1. This allows for some parts to enable L1 in certain configurations leading to better power savings. Also according to the same errata, Early Receive (ERT) should be disabled on 82573 when using jumbo frames.

2010-04-27ring-buffer: Make non-consuming read less expensive with lots of cpus.David Miller
When performing a non-consuming read, a synchronize_sched() is performed once for every cpu which is actively tracing. This is very expensive, and can make it take several seconds to open up the 'trace' file with lots of cpus. Only one synchronize_sched() call is actually necessary. What is desired is for all cpus to see the disabling state change. So we transform the existing sequence: for_each_cpu() { ring_buffer_read_start(); } where each ring_buffer_start() call performs a synchronize_sched(), into the following: for_each_cpu() { ring_buffer_read_prepare(); } ring_buffer_read_prepare_sync(); for_each_cpu() { ring_buffer_read_start(); } wherein only the single ring_buffer_read_prepare_sync() call needs to do the synchronize_sched(). The first phase, via ring_buffer_read_prepare(), allocates the 'iter' memory and increments ->record_disabled. In the second phase, ring_buffer_read_prepare_sync() makes sure this ->record_disabled state is visible fully to all cpus. And in the final third phase, the ring_buffer_read_start() calls reset the 'iter' objects allocated in the first phase since we now know that none of the cpus are adding trace entries any more. This makes openning the 'trace' file nearly instantaneous on a sparc64 Niagara2 box with 128 cpus tracing. Signed-off-by: David S.

2010-04-27ACPI: silence kmemcheck false positiveDan Carpenter
This addresses: https://bugzilla.kernel.org/show_bug.cgi?id=14998 We copy some strings into "event" but we leave the space after the NULL terminators uninitialized. Later in acpi_bus_receive_event() we copy the whole struct to another buffer with memcpy(). If the new buffer is stored on the stack, kmemcheck prints a warning about the unitialized space after the NULL terminators. It's true that the space is uninitialized, but it's harmless. The buffer is only used in acpi_system_read_event() and we don't read past the NULL terminators. This patch changes the kmalloc() to kzalloc() so that we initialize the memory and silence the kmemcheck warning.

The following commit broke CONFIG_RELOCATABLE support on FSL Book-E parts: commit 549e8152de8039506f69c677a4546e5427aa6ae7 Author: Paul Mackerras <paulus@samba.org> Date: Sat Aug 30 11:43:47 2008 +1000 powerpc: Make the 64-bit kernel as a position-independent executable The change to __va and __pa to use PAGE_OFFSET & MEMORY_START causes problems on the Book-E parts because we don't know MEMORY_START until after we parse the device tree. We need __va to work properly to even parse the device tree so we have a chicken an egg. So go back to using he other definition of __va/__pa on CONFIG_BOOKE and use the PAGE_OFFSET/MEMORY_START version on "Classic" PPC64. Also updated casts to handle phys_addr_t being a different size from unsigned long (ie 36-bit physical on PPC32). Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2010-04-26nfsd4: bug in read_bufNeil Brown
When read_buf is called to move over to the next page in the pagelist of an NFSv4 request, it sets argp->end to essentially a random number, certainly not an address within the page which argp->p now points to. So subsequent calls to READ_BUF will think there is much more than a page of spare space (the cast to u32 ensures an unsigned comparison) so we can expect to fall off the end of the second page. We never encountered thsi in testing because typically the only operations which use more than two pages are write-like operations, which have their own decoding logic. Something like a getattr after a write may cross a page boundary, but it would be very unusual for it to cross another boundary after that. Cc: stable@kernel.org Signed-off-by: J.

2010-04-26xfs: more swap extent fixes for dynamic fork offsetsDave Chinner
A new xfsqa test (226) with a prototype xfs_fsr change to try to handle dynamic fork offsets better triggers an assertion failure where the inode data fork is in btree format, yet there is room in the inode for it to be in extent format. The two inodes look like: before: ino 0x101 (target), num_extents 11, Max in-fork extents 6, broot size 40, fork offset 96 before: ino 0x115 (temp), num_extents 5, Max in-fork extents 3, broot size 40, fork offset 56 after: ino 0x101 (target), num_extents 5, Max in-fork extents 6, broot size 40, fork offset 96 after: ino 0x115 (temp), num_extents 11, Max in-fork extents 3, broot size 40, fork offset 56 Basically the target inode ends up with 5 extents in btree format, but it had space for 6 extents in extent format, so ends up incorrect. Notably here the broot size is the same, and that is where the kernel code is going wrong - the btree root will fit, so it lets the swap go ahead. The check should not allow the swap to take place if the number of extents while in btree format is less than the number of extents that can fit in the inode in extent format. Adding that check will prevent this swap and corruption from occurring. Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Christoph Hellwig <hch@lst.de>
