[PATCH v2] sata_sil24: Use memory barriers before issuing commands
The data in the cmd_block buffers may reach the main memory after the writel() to the device ports. This patch introduces two calls to wmb() to ensure the relative ordering.

[PATCH 1/1] perf record: Don't call newt functions when not initialized
From: Arnaldo Carvalho de Melo <acme(a)redhat.com> When processing events we want to give visual feedback to the user when using the newt browser, so there are ui_progress calls in __perf_session__process_events, but those should check if newt is being used.

[patch] change fs_struct.lock from rwlock to spinlock
struct fs_struct.lock is an rwlock with the read-side used to protect root and pwd members while taking references to them. Taking a reference to a path typically requires just 2 atomic ops, so the critical section is very small. Parallel read-side operations would have cacheline contention on the lock, the dentr... 10 Jun 2010 12:16

[PATCH for-2.6.35] virtio-pci: disable msi at startup
virtio-pci resets the device at startup by writing to the status register, but this does not clear the pci config space, specifically msi enable status which affects register layout. This breaks things like kdump when they try to use e.g. virtio-blk. Fix by forcing msi off at startup. Since pci.c already has ... 10 Jun 2010 12:16

[PATCH for-2.6.35] virtio_net: fix oom handling on tx
virtio net will never try to overflow the TX ring, so the only reason add_buf may fail is out of memory. Thus, we can not stop the device until some request completes - there's no guarantee anything at all is outstanding. Make the error message clearer as well: error here does not indicate queue full.
