This patch fixes some copy_user bugs: - kernelspace page faults that happen on behalf of a process are now correctly handled - add copy_user treatment so a fault handler which looks at the faulting instruction - added a note to do the same with the ldt stuff some day Signed-off-by:

This patch rounds up the size of a file used for iomem emulation up to the nearest page. This makes mmap work much better on the last page of the file. Signed-off-by:

On 2.4 hosts signals are delivered in numeric order when there are multiple pending at a given time. UML developed a subtle dependency on this ordering, which broke on 2.6 hosts and the separate process and thread signal queues. This patch eliminates that dependency. Signed-off-by:

This allows page faults to be delivered when they happen. Without this, it can happen that a page fault will occur when SIGSEGV is disabled, and the host will then just kill UML because it can't invoke the handler. Signed-off-by:

This patch is a whole lot of "obviously won't break anything" changes, including renaming the UML console functions more consistently notes to myself code movement making some functions static error path cleanup printk fixes Signed-off-by:

This patch saves and restores UML's idea of user mode across an interrupt. Without this, an interrupt arriving at the wrong time can cause UML to lose track of whether an interrupted handler is handing a userspace interrupt. From: Ingo Molnar Signed-off-by:

Fix a stupid bug in the sysrq handling in sn_console.c. Instead of eating all characters in the sysrq string (preventing them from getting to the tty layer), only eat those following 'ESC' since that's a pretty important character for various things. Please apply before 2.6.9 is released as the console is very unfriendly to use without it. Signed-off-by:

The following patch from Shaohua Li fixes a race with preempt enabled when a module containing a pm_idle callback is unloaded. Cached values in local variables need to be protected as RCU critical sections so that the synchronize_kernel() call in the unload path waits for all processors. There original bugzilla entry can be found at Shaohua, i had to make a small change (variable declaration after code in code block) so that it compiles with geriatric compilers such as the ones Andrew is attached to ;) http://bugzilla.kernel.org/show_bug.cgi?id=1716Signed-off-by:

SGI has been using this driver under Linux since 2001 but it was never included in the upstream kernel. SuSE did include the patch for mmtimer in SLES 9. The driver has been widely used for applications on the Altix platform. The timer hardware was designed around the multimedia timer specification by Intel but to my knowledge only SGI has implemented that standard. The driver was written by Jesse Barnes. The second revision has interrupt support removed and was somewhat simplified by removing one include file. Signed-off-by:

The useless iBCS2 supporting code is removed. However, according to old_ syscalls, I would like to keep backward- compatibility for a while, due to some old deb packages and executables for m32r.

A couple of GSM GPRS PCMCIA cards advertise 16 rather than 8 port sized windows for their serial interface. This breaks our current pcmcia serial driver which ignores any windows that are not 8 bytes. To avoid any regressions on other cards given this driver contains a certain amount of "magic" the patch below looks for 8 byte windows first so will not break existing supported cards (I hope ;)) Patch-by:

Currently metadata writing errors are ignored and not returned from sys_fsync on ext2 and ext3 filesystems. That is, at least ext2 and ext3. Both ext2 and ext3 resort to sync_inode() in their ->sync_inode method, which in turn calls ->write_inode. ->write_inode method has void type, and any IO errors happening inside are lost. Make ->write_inode return the error code? Signed-off-by:
