This patch (as1371) fixes a small bug in ohci-hcd. The HCD already knows how many ports the controller has; there's no need to go looking at the root hub's usb_device structure to find out. Especially since the root hub's maxchild value is set correctly only while the root hub is bound to the hub driver.

This patch (as1372) fixes a bug in the routine that chooses the default configuration to install when a new USB device is detected. The algorithm is supposed to look for a config whose first interface is for a non-vendor-specific class. But the way it's currently written, it will also accept a config with no interfaces at all, which is not very useful. (Believe it or not, such things do exist.)

There is a typo here. We should be testing "*dentry" which was just assigned instead of "dentry". This could result in dereferencing an ERR_PTR inside either usbfs_mkdir() or usbfs_create().

Commit 18eabe23 introduced DMA buffer ownership. Fix tusb6010 accordingly. To compile, also dummy musb_platform_save and restore functions need to be added. Also change the order of musb_read_fifo() to happen after dma_cache_maint to have the DMA operations completed before moving the remaining unaligned bytes with PIO. The DMA access and PIO touch different areas of the FIFO, so this change only makes the code a bit easier to follow. Tested on n810 and g_ether with variable size ping test. The test seems to fail for some ping sizes, but that seems to be a different problem.

The bypassing of this test is a leftover from 2.4 vintage kernels, and is no longer appropriate, or even used by KGDB. Currently KGDB uses probe_kernel_write() for all access to memory via the KGDB core, so it can simply be deleted. This fixes CVE-2010-1446.

On low memory boxes or those with highmem, kernel can OOM before the background reclaims inodes via xfssyncd. Add a shrinker to run inode reclaim so that it inode reclaim is expedited when memory is low. This is more complex than it needs to be because the VM folk don't want a context added to the shrinker infrastructure. Hence we need to add a global list of XFS mount structures so the shrinker can traverse them. Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Christoph Hellwig <hch@lst.de>

The pktcdvd driver uses proper locking and does not need the BKL in the ioctl and llseek functions of the character device, so kill both.

If dentry found stale happens to be a root of disconnected tree, we can't d_drop() it; its d_hash is actually part of s_anon and d_drop() would simply hide it from shrink_dcache_for_umount(), leading to all sorts of fun, including busy inodes on umount and oopsen after that. Bug had been there since at least 2006 (commit c636eb already has it), so it's definitely -stable fodder.
