PCI_ROM_ADDRESS is a 32 bit register and as such should be accessed using pci_bus_{read,write}_config_dword(). A recent audit of drivers/ turned up several cases of byte- and word-sized accesses. The harmful ones were fixed by Linus directly. This patches up one of the remaining harmless-but-still-wrong cases caught in the dragnet.

When doing ioctl HDIO_DRIVE_TASKFILE, the ide_task_t's request pointer is never set, but flagged_taskfile and do_rw_taskfile pass it as a parameter to the prehandler. The kernel will oops taskfile pio-out commands because of this (taskfile pio-in doesn't use a prehandler). This fix sets the request pointer at the time the request is created to stop this oops.

With the new fdtable locking rules, you have to protect fdtable with either ->file_lock or rcu_read_lock/unlock(). There are some places where we aren't doing either. This patch fixes those places. Signed-off-by:

Add smp_mb__after_clear_bit() to unlock_kiocb() AIO's use of wait_on_bit_lock()/wake_up_bit() forgot to add a barrier between clearing its lock bit and calling wake_up_bit() so wake_up_bit()'s unlocked waitqueue_active() can race. This puts AIO's use in line with the others and the comment above wake_up_bit(). Signed-off-by:

Kill an unused member of the i2c_adapter structure. This additionally fixes a potential bug, because <linux/i2c.h> doesn't include <linux/config.h>, so different files including <linux/i2c.h> could see a different definition of the i2c_adapter structure, depending on them including <linux/config.h> (or other header files themselves including <linux/config.h>) before <linux/i2c.h>, or not. Credits go to Jörn Engel for pointing me to the problem. Signed-off-by:

Al found a potential problem in epoll_create(), where the file->private_data member was set after fd_install(). This is obviously wrong since another thread might do a close() on that fd# before we set the file->private_data member. This goes over 2.6.13 and passes a few basic tests I've done here. (akpm: snuck in a kzalloc() cleanup too) Signed-off-by:

BUG fixes: The driver used to allocate memory with spinlock held which has been fixed in this patch. The driver was printing the entire buffer when it received a invalid entry in image_type. The fix is to only print a warning message and not the buffer. Usability enhancements: It is possible that due to user error the /sys/class/firmware/dell_rbu entries might be missing, this can happen if the user does the following echo 1 > /sys/class/firmware/dell_rbu/loading echo 0 > /sys/class/firmware/dell_rbu/loading This will make the entries in /sys/class/firmware/ to disappear and the only way get them back was bby unloading and loading the driver. This patch makes the user recreate these entries by echoing init in to image_type. This patch has been tested with Libsmbios and Dell OpenManage. Signed-off-by:

2.6.13 incorporated Alan Cox's patch for /proc/sys/fs/suid_dumpable (one version of this patch can be found here http://marc.theaimsgroup.com/?l=linux-kernel&m=109647550421014&w=2 ). This patch also made corresponding changes in kernel/sys.c to change the prctl() PR_SET_DUMPABLE operation so that the permitted range of 'arg2' was modified from 0..1 to 0..2. However, a corresponding change was not made for PR_GET_DUMPABLE: if the dumpable flag is non-zero, then PR_GET_DUMPABLE always returns 1, so that the caller can't determine the true setting of this flag.

Added ppc_sys device and system definitions for PowerQUICC I devices. This will allow drivers for PQI to be proper platform device drivers. Currently sys section contains only MPC885 and MPC866. Identification should be done with identify_ppc_sys_by_name call, with board-specific "name" string passed, since PQI do not have any register that could identify the SOC. Signed-off-by:

The poster child for this patch is the third tuntap_user hunk. When an ioctl fails, it properly closes the opened file descriptor and returns. However, the close resets errno to 0, and the 'return errno' that follows returns 0 rather than the value that ioctl set. This caused the caller to believe that the device open succeeded and had opened file descriptor 0, which caused no end of interesting behavior. The rest of this patch is a pass through the UML sources looking for places where errno could be reset before being passed back out. A common culprit is printk, which could call write, being called before errno is returned. In some cases, where the code ends up being much smaller, I just deleted the printk. There was another case where a caller of run_helper looked at errno after a failure, rather than the return value of run_helper, which was the errno value that it wanted. Signed-off-by:

This patch implements a stack trace for a thread, not unlike sysrq-t does. The advantage to this is that a break point can be placed on showreqs, so that upon showing the stack, you jump immediately into the debugger. While sysrq-t does the same thing, sysrq-t shows *all* threads stacks. It also doesn't work right now. In the future, I thought it might be acceptable to make this show all pids stacks, but perhaps leaving well enough alone and just using sysrq-t would be okay. For now, upon receiving the stack command, UML switches context to that thread, dumps its registers, and then switches context back to the original thread. Since UML compacts all threads into one of 4 host threads, this sort of mechanism could be expanded in the future to include other debugging helpers that sysrq does not cover. Note by jdike - The main benefit to this is that it brings an arbitrary thread back into context, where it can be examined by gdb. The fact that it dumps it stack is secondary. This provides the capability to examine a sleeping thread, which has existed in tt mode, but not in skas mode until now. Also, the other threads, that sysrq doesn't cover, can be gdb-ed directly anyway. Signed-off-by: Allan Graves<allan.graves@gmail.com> Signed-off-by:
