2006-12-07[PATCH] IPMI: pass sysfs name from lower level driverCorey Minyard1-0/+1
Pass in the sysfs name from the lower-level IPMI driver, as the coming IPMI serial driver will need that to link properly from the serial device sysfs directory.

2006-12-07[PATCH] nbd: show nbd client pid in sysfsPaul Clements1-0/+1
Allow nbd to expose the nbd-client daemon's PID in /sys/block/nbd<x>/pid. This is helpful for tracking connection status of a device and for determining which nbd devices are currently in use.

2006-12-07[PATCH] aio: remove ki_retried debugging memberBenjamin LaHaise1-2/+0
Remove the ki_retried member from struct kiocb. I think the idea was bounced around a while back, but Arnaldo pointed out another reason that we should dig it up when he pointed out that the last cacheline of struct kiocb only contains 4 bytes. By removing the debugging member, we save more than the 8 byte on 64 bit machines.

2006-12-07[PATCH] Kexec / Kdump: Unify elf note codeMagnus Damm1-0/+1
The elf note saving code is currently duplicated over several architectures. This cleanup patch simply adds code to a common file and then replaces the arch-specific code with calls to the newly added code. The only drawback with this approach is that s390 doesn't fully support kexec-on-panic which for that arch leads to introduction of unused code.

2006-12-07[PATCH] fs: reorder some 'struct inode' fields to speedup i_size manipulationsEric Dumazet1-4/+4
On 32bits SMP platforms, 64bits i_size is protected by a seqcount (i_size_seqcount). When i_size is read or written, i_size_seqcount is read/written as well, so it make sense to group these two fields together in the same cache line. This patch moves i_size_seqcount next to i_size, and also moves i_version to let offsetof(struct inode, i_size) being 0x40 instead of 0x3c (for 32bits platforms). For 64 bits platforms, i_size_seqcount doesnt exist, and the move of a 'long i_version' should not introduce a new hole because of padding.

2006-12-07[PATCH] kprobes: enable booster on the preemptible kernelMasami Hiramatsu1-1/+1
When we are unregistering a kprobe-booster, we can't release its instruction buffer immediately on the preemptive kernel, because some processes might be preempted on the buffer. The freeze_processes() and thaw_processes() functions can clean most of processes up from the buffer. There are still some non-frozen threads who have the PF_NOFREEZE flag. If those threads are sleeping (not preempted) at the known place outside the buffer, we can ensure safety of freeing. However, the processing of this check routine takes a long time. So, this patch introduces the garbage collection mechanism of insn_slot. It also introduces the "dirty" flag to free_insn_slot because of efficiency. The "clean" instruction slots (dirty flag is cleared) are released immediately. But the "dirty" slots which are used by boosted kprobes, are marked as garbages. collect_garbage_slots() will be invoked to release "dirty" slots if there are more than INSNS_PER_PAGE garbage slots or if there are no unused slots.

2006-12-07[PATCH] Fix the size limit of compat space msgsizesuzuki1-0/+6
Currently we allocate 64k space on the user stack and use it the msgbuf for sys_{msgrcv,msgsnd} for compat and the results are later copied in user [ by copy_in_user]. This patch introduces helper routines for sys_{msgrcv,msgsnd} as below: do_msgsnd() : Accepts the mtype and user space ptr to the buffer along with the msqid and msgflg. do_msgrcv() : Accepts a kernel space ptr to mtype and a userspace ptr to the buffer. The mtype has to be copied back the user space msgbuf by the caller. These changes avoid the need to allocate the msgsize on the userspace ( thus removing the size limt ) and the overhead of an extra copy_in_user().

2006-12-07[PATCH] taskstats: cleanup do_exit() pathOleg Nesterov1-15/+2
do_exit: taskstats_exit_alloc() ... taskstats_exit_send() taskstats_exit_free() I think this is not good, let it be a single function exported to the core kernel, taskstats_exit(), which does alloc + send + free itself.

2006-12-07[PATCH] probe_kernel_address() needs to do set_fs()Andrew Morton1-0/+8
probe_kernel_address() purports to be generic, only it forgot to select KERNEL_DS, so it presently won't work right on all architectures. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-12-07[PATCH] parport_pc: Add support for OX16PCI952 parallel portRyan Underwood1-0/+1

2006-12-07[PATCH] pull in necessary header files for cdev.hJan Engelhardt1-0/+4
linux/cdev.h uses struct kobject and other structs and should therefore include them. Currently, a module either needs to add the missing includes itself, or, in case a module includes other headers already, needs to put <linux/cdev.h> last, which goes against a alphabetically-sorted include list.

2006-12-07[PATCH] SysRq-X: show blocked tasksIngo Molnar1-1/+10

2006-12-07[PATCH] fuse: add DESTROY operationMiklos Szeredi1-0/+1
Add a DESTROY operation for block device based filesystems. With the help of this operation, such a filesystem can flush dirty data to the device synchronously before the umount returns. This is needed in situations where the filesystem is assumed to be clean immediately after unmount (e.g. ejecting removable media).

2006-12-07[PATCH] fuse: update userspace interface to version 7.8Miklos Szeredi1-3/+9
Add a flag to the RELEASE message which specifies that a FLUSH operation should be performed as well. This interface update is needed for the FreeBSD port, and doesn't actually touch the Linux implementation at all. Also rename the unused 'flush_flags' in the FLUSH message to 'unused'.

2006-12-07[PATCH] serial uartlite driverPeter Korsgaard1-0/+2
Add a driver for the Xilinx uartlite serial controller used in boards with the PPC405 core in the Xilinx V2P/V4 fpgas. The hardware is very simple (baudrate/start/stopbits fixed and no break support). See the datasheet for details: http://www.xilinx.com/bvdocs/ipcenter/data_sheet/opb_uartlite.pdf See http://thread.gmane.org/gmane.linux.serial/1237/ for the email thread.

2006-12-07[PATCH] swsusp: thaw userspace and kernel space separatelyNigel Cunningham1-1/+8
