Change defconfig file's location from arch/m32r/{platform}/defconfig* to arch/m32r/configs/{platform}_defconfig. Applying this patch, we can use defconfig file for each m32r platform easily, like other architectures. ex.

2007-08-31NFS: Fix the mount regressionTrond Myklebust
This avoids the recent NFS mount regression (returning EBUSY when mounting the same filesystem twice with different parameters). The best I can do given the constraints appears to be to have the kernel first look for a superblock that matches both the fsid and the user-specified mount options, and then spawn off a new superblock if that search fails. Note that this is not the same as specifying nosharecache everywhere since nosharecache will never attempt to match an existing superblock.

2007-08-31x86: be even more careful about checking the stack frame on dumpingLinus Torvalds
lguest didn't initialize the kernel stack the way a real i386 kernel does, and ended up triggering a corner-case in the stack frame checking that doesn't happen on naive i386, and that the stack dumping didn't handle quite right. This makes the frame handling more correct, and tries to clarify the code at the same time so that it's a bit more obvious what is going on.

2007-08-31Do not use the ia64 clocksource on non-ia64 architecturesLinus Torvalds
The HPET clocksource in drivers/char/hpet.c was written as generic code for ia64, but it is not yet ready to replace the native HPET clocksource implementations that the i386/x86-64 architectures use. On x86[-64], trying to register this clocksource results in potentially multiple hpet-based clocksources being registered, and if the ia64 one is chosen on x86_64 some users have experienced hangs. Eventually all three architectures may end up using the same code, but that is not the case right now.

2007-08-31qeth: Drop ARP packages on HiperSockets interface with NOARP attribute.Klaus D. Wacker

2007-08-31qeth: ungrouping a device must not be interruptibleUrsula Braun
Problem: A recovery thread must not be active when device is removed. In qeth_remove_device() an interruptible wait operation is used to wait until a qeth recovery thread is finished. If a user really interrupts the ungroup operation of a qeth device while a recovery is running, cio and qeth are out of sync (device already removed from cio, but kept in qeth). A following module unload of qeth results in a kernel OOPS here. Solution: Do not allow interruption of ungroup operation to guarantee finishing of a potentially running qeth recovery thread.

2007-08-31hugepage: fix broken check for offset alignment in hugepage mappingsDavid Gibson
For hugepage mappings, the file offset, like the address and size, needs to be aligned to the size of a hugepage. In commit 68589bc353037f233fe510ad9ff432338c95db66, the check for this was moved into prepare_hugepage_range() along with the address and size checks. But since BenH's rework of the get_unmapped_area() paths leading up to commit 4b1d89290b62bb2db476c94c82cf7442aab440c8, prepare_hugepage_range() is only called for MAP_FIXED mappings, not for other mappings. This means we're no longer ever checking for an aligned offset - I've confirmed that mmap() will (apparently) succeed with a misaligned offset on both powerpc and i386 at least. This patch restores the check, removing it from prepare_hugepage_range() and putting it back into hugetlbfs_file_mmap(). I'm putting it there, rather than in the get_unmapped_area() path so it only needs to go in one place, than separately in the half-dozen or so arch-specific implementations of hugetlb_get_unmapped_area().

2007-08-31sigqueue_free: fix the race with collect_signal()Oleg Nesterov
Spotted by taoyue <yue.tao@windriver.com> and Jeremy Katz <jeremy.katz@windriver.com>. collect_signal: sigqueue_free: list_del_init(&first->list); if (!list_empty(&q->list)) { // not taken } q->flags &= ~SIGQUEUE_PREALLOC; __sigqueue_free(first); __sigqueue_free(q); Now, __sigqueue_free() is called twice on the same "struct sigqueue" with the obviously bad implications. In particular, this double free breaks the array_cache->avail logic, so the same sigqueue could be "allocated" twice, and the bug can manifest itself via the "impossible" BUG_ON(!SIGQUEUE_PREALLOC) in sigqueue_free/send_sigqueue. Hopefully this can explain these mysterious bug-reports, see http://marc.info/?t=118766926500003 http://marc.info/?t=118466273000005 Alexey Dobriyan reports this patch makes the difference for the testcase, but nobody has an access to the application which opened the problems originally.

2007-08-31spi: correct name for spi_txx9Atsushi Nemoto
Correct the name of the spi_txx9 driver (and their in-tree user) instead of MODULE_ALIAS workaround. This would be preferable in the long term.

2007-08-31SPI driver hotplug/coldplug fixesDavid Brownell
Update various SPI drivers so they properly support - coldplug through "modprobe $(cat /sys/devices/.../modalias)" - hotplug through "modprobe $(MODALIAS)" The basic rule for platform, SPI, and (new style) I2C drivers is just to make sure that modprobing the driver name works. In this case, all the relevant drivers are platform drivers, and this patch either (a) Changes the driver name, if no in-tree code would break; this is simpler and thus preferable in the long term. (b) Adds MODULE_ALIAS directives, when in-tree platforms declare devices using the current driver name; less desirable. Most systems will link SPI controller drivers statically, but there's no point in being needlessly broken.

2007-08-31Assign task_struct.exit_code before taskstats_exit()Jonathan Lim
taskstats.ac_exitcode is assigned to task_struct.exit_code in bacct_add_tsk() through the following kernel function calls: do_exit() taskstats_exit() fill_pid() bacct_add_tsk() The problem is that in do_exit(), task_struct.exit_code is set to 'code' only after taskstats_exit() has been called. So we need to move the assignment before taskstats_exit().

We better select a font when the newport driver is a module or the user experience might suffer. Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Cc: "Antonino A.

2007-08-31Fix possible NULL pointer dereference in udf_table_free_blocks()Jan Kara
Fix possible NULL pointer dereference when freeing blocks in case table of free space is used. Also fix handling of the case when we need to move extent from one block to another one to make space for indirect extent. BTW: Nobody seem to have ever used this code.

2007-08-31UDF: handle wrong superblock betterJan Kara
If UDF superblock is incorrect, we can fail to find a table of free / allocated space and consequently Oops. Handle this situation more gracefully by ignoring the broken UDF partition.
