* MIPS: Simplify and correct interrupt handling for MSP4200Shane McDonald2009-08-031-9/+1
| | | | | | | | | | | | The current interrupt handling code for the MSP4200 always masks an interrupt before acknowledging it. This is not required, as that will be handled by the level interrupt handler. This change simplifies the MSP4200 code to remove the masking in the ack routine, and makes sure that the minimum required operation is performed for masking and acking, rather than always both masking and acking the interrupt.

* MIPS: MSPxxxx: define MIPS34K_MISSED_ITLB_WAR for other PMC-Sierra SoCFlorian Fainelli2009-08-031-0/+2

* MIPS: Fix loading of modules with unresolved weak symbolsGabor Juhos2009-08-031-2/+2
| | | | | | | | | | | | | | | | | Loading of modules with unresolved weak symbols fails on MIPS since '88173507e4fc1e7ecd111b0565e8cba0cb7dae6d'. Modules: handle symbols that have a zero value The module subsystem cannot handle symbols that are zero.

* MIPS: Avoid clobbering struct pt_regs in kthreadsDavid Daney2009-08-033-4/+8
| | | | | | | | | | | | | | | | | | | The resume() implementation octeon_switch.S examines the saved cp0_status register. We were clobbering the entire pt_regs structure in kernel threads leading to random crashes. When switching away from a kernel thread, the saved cp0_status is examined and if bit 30 is set it is cleared and the CP2 state saved into the pt_regs structure. Since the kernel thread stack overlaid the pt_regs structure this resulted in a corrupt stack. When the kthread with the corrupt stack was resumed, it could crash if it used any of the data in the stack that was clobbered. We fix it by moving the kernel thread stack down so it doesn't overlay pt_regs. Signed-off-by: David Daney <ddaney@caviumnetworks.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

| * md: Use revalidate_disk to effect changes in size of device.NeilBrown2009-08-034-33/+9
| | | | | | | | | | | | | | | | | | | | | | | | As revalidate_disk calls check_disk_size_change, it will cause any capacity change of a gendisk to be propagated to the blockdev inode. So use that instead of mucking about with locks and i_size_write. Also add a call to revalidate_disk in do_md_run and a few other places where the gendisk capacity is changed.

| * md: allow raid5_quiesce to work properly when reshape is happening.NeilBrown2009-08-031-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ->quiesce method is not supposed to stop resync/recovery/reshape, just normal IO. But in raid5 we don't have a way to know which stripes are being used for normal IO and which for resync etc, so we need to wait for all stripes to be idle to be sure that all writes have completed. However reshape keeps at least some stripe busy for an extended period of time, so a call to raid5_quiesce can block for several seconds needlessly. So arrange for reshape etc to pause briefly while raid5_quiesce is trying to quiesce the array so that the active_stripes count can drop to zero. Signed-off-by: NeilBrown <neilb@suse.de>
| * md/raid5: set reshape_position correctly when reshape starts.NeilBrown2009-08-031-1/+1
| | | | | | | | | | | | | | | | | | As the internal reshape_progress counter is the main driver for reshape, the fact that reshape_position sometimes starts with the wrong value has minimal effect. It is visible in sysfs and that is all. Signed-off-by: NeilBrown <neilb@suse.de>
| * md: Handle growth of v1.x metadata correctly.NeilBrown2009-08-031-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The v1.x metadata does not have a fixed size and can grow when devices are added. If it grows enough to require an extra sector of storage, we need to update the 'sb_size' to match. Without this, md can write out an incomplete superblock with a bad checksum, which will be rejected when trying to re-assemble the array.

| | | | | | | | | | | | | | | | We trust the 'desc_nr' field in v1.x metadata enough to use it as an index in an array. This isn't really safe. So range-check the value first. Signed-off-by: NeilBrown <neilb@suse.de>
| * md: when a level change reduces the number of devices, remove the excess.NeilBrown2009-08-031-0/+7
| | | | | | | | | | | | | | | | | | | | | | When an array is changed from RAID6 to RAID5, fewer drives are needed. So any device that is made superfluous by the level conversion must be marked as not-active. For the RAID6->RAID5 conversion, this will be a drive which only has 'Q' blocks on it.

| * md: Push down data integrity code to personalities.Andre Noll2009-08-037-33/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch replaces md_integrity_check() by two new public functions: md_integrity_register() and md_integrity_add_rdev() which are both personality-independent. md_integrity_register() is called from the ->run and ->hot_remove methods of all personalities that support data integrity. The function iterates over the component devices of the array and determines if all active devices are integrity capable and if their profiles match. If this is the case, the common profile is registered for the mddev via blk_integrity_register(). The second new function, md_integrity_add_rdev() is called from the ->hot_add_disk methods, i.e. whenever a new device is being added to a raid array. If the new device does not support data integrity, or has a profile different from the one already registered, data integrity for the mddev is disabled. For raid0 and linear, only the call to md_integrity_register() from the ->run method is necessary. Signed-off-by: Andre Noll <maan@systemlinux.org> Signed-off-by: NeilBrown <neilb@suse.de>

Userspace needs some love to support the two-stage ejection nicely, but it is simple enough to do through udev rules (you don't even need HAL) so this wouldn't justify fixing the dock and bay subdrivers, either. That leaves warm-swap bays (_EJ3) support for thinkpad-acpi, as well as support for the weird dock of the model 570, but since such support has never left the "experimental" stage, it is also not a strong enough reason to find a way to fix this code. Users of ThinkPads with warm-swap bays are urged to request that _EJ3 support be added to the regular ACPI dock driver, if such feature is indeed useful for them.

| | * | | thinkpad-acpi: disable broken bay and dock subdriversHenrique de Moraes Holschuh2009-08-011-1/+3
| | |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the ThinkPad-ACPI bay and dock drivers are completely broken, and cause a NULL pointer derreference in kernel mode (and, therefore, an OOPS) when they try to issue events (i.e. on dock, undock, bay ejection, etc). OTOH, the standard ACPI dock driver can handle the hotplug bays and docks of the ThinkPads just fine (including batteries) as of 2.6.27. In fact, it does a much better job of it than thinkpad-acpi ever did. It is just not worth the hassle to find a way to fix this crap without breaking the (deprecated) thinkpad-acpi dock/bay ABI. This is old, deprecated code that sees little testing or use. As a quick fix suitable for -stable backports, mark the thinkpad-acpi bay and dock subdrivers as BROKEN in Kconfig. The dead code will be removed by a later patch. This fixes bugzilla #13669, and should be applied to 2.6.27 and later.

| | * | | hp-wmi: check that an input device exists in resume handlerFrans Pop2009-07-301-5/+7

So check that an input device exists before trying to set the docking and tablet mode state during resume.
