Fix bug identifued by Richard Purdie <rpurdie@rpsys.net>. oprofile calls check_user_page_readable() from interrupt context, so we deadlock over various VFS locks. But check_user_page_readable() doesn't imply either a read or a write of the page's contents. Change __follow_page() so that check_user_page_readable() can tell __follow_page() that we're not accessing the page's contents, and use that info to avoid the troublesome lock-takings. Also, make follow_page() inline for the single callsite in memory.c to save a bit of stack space. Signed-off-by:

Oliver Paukstadt from our test department is testing the xip patches in Linus' git-tree. He found a problem that shows when reading a file that contains sparse blocks (holes) on a -o xip mounted ext2 filesystem: the BUG_ON() in fs/ext2/xip.c:40 triggers where it should not. The problem was introduced by a cleanup in my previous patch, this patch fixes it. Signed-off-by:

This patch fixes a microcode lockup in my CD-ROM adapters when a blank CD is inserted. However, do not try to burn CDs yet! I'm pretty sure that trying it will end in coasters. - Fix a few cases where we were unable to resynchronize with replies for previous commands. The main thing is to keep reading replies in case of a stall. This is done with the new state CLRRS. - Since I am forgetting the basic state machine already, document it. - Move counter increments in the looping path in its own function. - Fix a harmless buglet in case CSW read fails to submit: do not override state. - Implement the Alan Stern's idea for adaptive signature checking.

The jsm driver uses a static number of 253. The major number 253 is a reserved for "LOCAL/EXPERIMENTAL USE" by both char and block devices. So take advantage of the dynamic allocation of major number by the kernel. Signed-off-by:

This patch adds support for the Olitec ISDN PCI card in the hisax gazel driver. The gazel driver supports this card, but wasn't aware of its PCI ids. Users used to modify the PCI ids of a supported card in include/linux/pci_ids.h and recompile their kernel to get this card running, as said in most Howtos. This patch makes the hisax gazel driver recognize the PCI ids of the Olitec ISDN PCI card. Signed-off-by:

Adds a missing check for an error return code from scsi_sysfs_add_sdev. This resolves entry #4863 in the OSDL bugzilla. Although in that bug report the failure occurred because of a confusion over scanning vs. rescanning, in general add_sdev can fail for a number of reasons (the simplest being insufficient memory) and the caller should cope properly.

Fix the recent off-by-one fix in the itimer code: 1. The repeating timer is figured using the requested time (not +1 as we know where we are in the jiffie). 2. The tests for interval too large are left to the time_val to jiffie code. Signed-off-by:

reiserfs_new_inode() can call iput() with the xattr lock held. This will cause a deadlock to occur when reiserfs_delete_xattrs() is called to clean up. The following patch releases the lock and reacquires it after the iput. This is safe because interaction with xattrs is complete, and the relock is just to balance out the release in the caller. The locking needs some reworking to be more sane, but that's more intrusive and I was just looking to fix this bug. Signed-off-by:
