2009-07-01md/raid5: suspend shouldn't affect read requests.NeilBrown
md allows write to regions on an array to be suspended temporarily. This allows user-space to participate is aspects of reshape. In particular, data can be copied with not risk of a race. We should not be blocking read requests though, so don't. Cc: stable@kernel.org Signed-off-by: NeilBrown <neilb@suse.de>
2009-07-01md: tidy up error paths in md_allocNeilBrown
As the recent bug in md_alloc showed, having a single exit path for unlocking and putting is a good idea. So restructure md_alloc to have a single mutex_unlock and mddev_put, and use gotos where necessary. Found-by: Jiri Slaby <jirislaby@gmail.com> Signed-off-by: NeilBrown <neilb@suse.de>
2009-07-01md: fix error path when duplicate name is found on md device creation.NeilBrown
When an md device is created by name (rather than number) we need to check that the name is not already in use. If this check finds a duplicate, we return an error without dropping the lock or freeing the newly create mddev. This patch fixes that.

2009-07-01md: avoid dereferencing NULL pointer when accessing suspend_* sysfs attributes.NeilBrown
If we try to modify one of the md/ sysfs files suspend_lo or suspend_hi when the array is not active, we dereference a NULL. Protect against that. Cc: stable@kernel.org Signed-off-by: NeilBrown <neilb@suse.de>

2009-06-29ide: memory overrun in ide_get_identity_ioctl() on big endian machines using ↵Christian Engelmayer
ioctl HDIO_OBSOLETE_IDENTITY This patch fixes a memory overrun in function ide_get_identity_ioctl() which chooses the size of a memory buffer depending on the ioctl command that led to the function call, however, passes that buffer to a function which needs the buffer size to be always chosen unconditionally. Due to conditional compilation the memory overrun can only happen on big endian machines. The error can be triggered using ioctl HDIO_OBSOLETE_IDENTITY. Usage of ioctl HDIO_GET_IDENTITY is safe.

2009-06-29ide: fix resume for CONFIG_BLK_DEV_IDEACPI=yBartlomiej Zolnierkiewicz
commit 2f0d0fd2a605666d38e290c5c0d2907484352dc4 ("ide-acpi: cleanup do_drive_get_GTF()") didn't account for the lack of hwif->acpidata check in generic_ide_suspend() [ indirect user of do_drive_get_GTF() through ide_acpi_exec_tfs() ] resulting in broken resume when ACPI support is enabled but ACPI data is unavailable. Fix it by adding ide_port_acpi() helper for checking if port needs ACPI handling and cleaning generic_ide_{suspend,resume}() to use it instead of hiding hwif->acpidata and ide_noacpi checks in IDE ACPI helpers (this should help in preventing similar bugs in the future).

2009-06-29tty: Fix the leak in tty_ldisc_releaseAlan Cox
Currently we reinit the ldisc on final tty close which is what the old code did to ensure that if the device retained its termios settings then it had the right ldisc. tty_ldisc_reinit does that but also leaves us with the reset ldisc reference which is then leaked. At this point we know the port will be recycled so we can kill the ldisc off completely rather than try and add another ldisc free up when the kref count hits zero. At this point it is safe to keep the ldisc closed as tty_ldisc waiting methods are only used from the user side, and as the final close we are the last such reference. Interrupt/driver side methods will always use the non wait version and get back a NULL. Found with kmemleak and investigated/identified by Catalin Marinas.

2009-06-29fs: allow d_instantiate to be called with negative parent dentryJeremy Kerr
The new fsnotify infrastructure (starting at 90586523) causes an oops in spufs, where we populate a directory with files before instantiating the directory itself. The new changes seem to have introduced an assumption that a dentry's parent will be positive when instantiating. This change makes it once again possible to d_instantiate a dentry with a negative parent, and brings __fsnotify_d_instantiate() into line with inotify_d_instantiate(), which already has this NULL check.

With CONFIG_PPC_64K_PAGES configured (a default in PPC), MAX_SKB_FRAGS drops to 3 and we were crossing the array limits on skb_shinfo(skb)->frags[]. Now we coalesce the frags from the same physical page into one slot in skb_shinfo(skb)->frags[] and go to the next index when the frag is from different physical page.

2.6.31-rc introduced an architecture level set checker based on facility bits. e.g. if the kernel is compiled to run only on z9, several facility bits are checked very early and the kernel refuses to boot if a z9 specific facility is missing. Until now kvm on s390 did not implement the store facility extended (STFLE) instruction. A 2.6.31-rc kernel that was compiled for z9 or higher did not boot in kvm. This patch implements stfle.

This reverts commit 95ee14e4379c5e19c0897c872350570402014742. Mikael Petterson <mikepe@it.uu.se> reported that at least one of his systems will not boot as a result. We have ruled out the detection algorithm malfunctioning, so it is not a matter of producing the incorrect bitmasks; rather, something in the application of them fails. Revert the commit until we can root cause and correct this problem. -stable team: this means the underlying commit should be rejected.
