I have a problem with errors=panic on ext3. When a panic occurs, the error event is not recorded anywhere. So after the reboot, e2fsck doesn't kick in, the file system gets mounted again and the box panics again... Patch below moves the ERRORS_PANIC test down a bit so the journal is aborted before panic() is called. Signed-off-by:

The use of U+F800 to U+F804 has been deprecated since 2003; this makes the deprecation effective by replacing these characters with the officially assigned U+23BA to U+23BD. It also updates unicode.txt to match the latest version from the LANANA webpage. Signed-off-by:

So far the X.Org/XFree86 Xservers use internal functions to perform saving/restoring of console fonts. This doesn't work under all circumstances and has disadvantages: 1. On some platforms (IA64) X needs to POST the BIOS before it even has a chance to access the hardware itself. This POSTing will usually undo any changes to the graphics hardware that the kernel may have done. 2. More and more drivers fully rely on BIOS support. However the BIOS functions which could be used to save/restore register settings may be broken so the only way of mode save/restore is getting/setting the BIOS mode ID. This will restore the BIOSes default fonts, not the custom font that the user may have loaded. I would like to utilize the kernel's save/restore console fonts ioctls to save/restore the text mode console fonts from inside X. The patch does two things: 1. Eliminates the optimization that returns from vgacon_adjust_height() early (without reprogramming the HW) when the hight of the font hasn't changed. 2. Resets the stored 'from' and 'to' lines for the text cursor in vgacon_adjust_height() to cause vgacon_set_cursor_size() reprogram the textcursor start and end line. These are necessary to sanitize the HW in case something other than the kernel has changed the register values without restoring them properly. I'm fully aware that in the long run we will need to look into a new driver model for graphics where no two instances fight over who gets register access. However such a model won't be created nor will we get the majority of the drivers ported over night. Therefore we need to find an interim solution for the most pressing problems. Signed-off-by:

The newly merged frv do_IRQ code calls softirq_pending(), but always with the current cpu as argument - switch to local_softirq_pending(). Btw, this usage look bogus to me, any reason you need to call do_softirq again after you did four lines above in irq_exit(), David? Signed-off-by:

Currently it's up to the filesystem ->permission method to check whether the filesystem is readonly or the file marked immutable. But this is really a VFS decision, and the distintion becomes more important when moving to per-mountpoint read only flags. For most filesystems that have been using generic_permission this is not change in behaviour. For those that we're missing the check (cifs without CIFS_MOUNT_NO_PERM and coda [1]) this is a bugfix. Both reiserfs and xfs have this check still in their ->permission routine because they call it from other places aswell. I'll try switching them over to generic_permission and will take care of this one. [1] coda_ioctl_permission always returns 0, aka always grants access, which looks more than fishy to me.

Remove unnecessary division and modulo from ext3 code in often used paths. Without the patch an oprofile of dbench load shows ext3_get_group_desc() uses 0.84% and ext3_group_sparse() 1.51%, with the patch the numbers are 0.33% and 0.27% respectively. Signed-off-by:

expand_files() cleanup: Make expand_files() common code for fork.c:fork/copy_files(), open.c:open/get_unused_fd() and fcntl.c:dup/locate_fd(). expand_files() does both expand_fd_array and expand_fd_set based on the need. This is used in dup(). open() and fork() duplicates the work of expand files. At all places we check for expanding fd array, we also check for expanding fdset. There is no need of checking and calling them seperately. This change also moves the expand_files to file.c from fcntl.c, and makes the expand_fd_array and expand_fd_set local to that file.

This passes pm_message_t down to PCI drivers. Ugly translation code can be removed and this will allow PCI devices to do right thing during swsusp snapshot -- like not unneccessarily blanking display. Only obscure /sysfs code passes anything but 3 to pci_device_suspend, anyway, so this is pretty close to a nop. Signed-off-by:

Fix SMP race in NMI watchdog on i386/x86-64 Fix a long standing SMP Setup race in the NMI watchdog. The watchdog would tick from very early and check if all CPUs increase their timer interrupts. For that it would check the cpu_online_map. Now if a CPU took too long to boot the watchdog would trigger prematurely because the CPU didn't increase its timer count yet. Fix is to check cpu_callin_map instead of cpu_online_map because the first is only set when a CPU started its timer interrupt. I fixed it on i386 and x86-64. Description of the problem from Manpreet Singh. Thanks. Cc: <manpreet@fabric7.com> Signed-off-by:

Fix a long standing race in x86-64 SMP TLB handling. When a mm is freed and another thread exits to a lazy TLB thread (like idle) the freed user page tables would be still kept loaded in the idle thread. When an interrupt does a prefetch on NULL the CPU would try to follow it and read random data. This could lead to machine checks on Opterons in some cases. Credit goes to some unnamed debugging wizards at AMD who described the problem. All blame to me. I did the fix based on their description. Signed-off-by:

In unprivileged Xen domains, all that __ioremap() does is a "return NULL", which causes dmi_iterate() to crash the kernel at boot time. This trivial check bails dmi_iterate() out of the loop when it finds that the ioremap() returned a NULL pointer. (akpm: this fix goes beyond xen - ioremap can return NULL) Signed-off-by:
