2008-11-10libata: revert convert-to-block-tagging patchesTejun Heo
This patch reverts the following three commits which convert libata to use block layer tagging. 43a49cbdf31e812c0d8f553d433b09b421f5d52c e013e13bf605b9e6b702adffbe2853cfc60e7806 2fca5ccf97d2c28bcfce44f5b07d85e74e3cd18e Although using block layer tagging is the right direction, due to the tight coupling among tag number, data structure allocation and hardware command slot allocation, libata doesn't work correctly with the current conversion. The biggest problem is guaranteeing that tag 0 is always used for non-NCQ commands. Due to the way blk-tag is implemented and how SCSI starts and finishes requests, such guarantee can't be made. I'm not sure whether this would actually break any low level driver but it doesn't look like a good idea to break such assumption given the frailty of ATA controllers. So, for the time being, keep using the old dumb in-libata qc allocation.

2008-11-09Don't ask twice about not including staging driversLinus Torvalds
The "Exclude staging drivers" question is there so that we don't build staging drivers for allyesconfig or allnoconfig settings, but it's very irritating when you've already said "no" to staging drivers earlier. There is absolutely no point in declining twice - once you've declined the staging drivers, you're done. So make the second question depend on the first question having been answered in the affirmative. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-11-06atmel_serial: keep clock off when it's not neededDavid Brownell
The atmel_serial driver is mismanaging its clock by leaving it on at all times ... the whole point of clock management is to leave it off unless it's actively needed, which conserves power!! Although the kernel doesn't actually hang without my fix, it does discard quite a lot of early console output. The result still looks correct: usart users= 1 on 35000000 Hz, for atmel_usart.0 usart users= 0 off 35000000 Hz, for atmel_usart.2 when using ttyS0 as serial console.

2008-11-06fbdev: fix fb_compat_ioctl() deadlocksGeert Uytterhoeven
commit 3e680aae4e53ab54cdbb0c29257dae0cbb158e1c ("fb: convert lock/unlock_kernel() into local fb mutex") introduced several deadlocks in the fb_compat_ioctl() path, as mutex_lock() doesn't allow recursion, unlike lock_kernel(). This broke frame buffer applications on 64-bit systems with a 32-bit userland. commit 120a37470c2831fea49fdebaceb5a7039f700ce6 ("framebuffer compat_ioctl deadlock") fixed one of the deadlocks. This patch fixes the remaining deadlocks: - Revert commit 120a37470c2831fea49fdebaceb5a7039f700ce6, - Extract the core logic of fb_ioctl() into a new function do_fb_ioctl(), - Change all callsites of fb_ioctl() where info->lock is already held to call do_fb_ioctl() instead, - Add sparse annotations to all routines that take info->lock.

We broke it in 2.6.27-rc on or about 20080804. Some installers are broken if this symlink does not exist and they may not detect the logical drives configured on the controller.

2008-11-06Revert "ath5k: honor FIF_BCN_PRBRESP_PROMISC in STA mode"John W. Linville
Unfortunately, the result was that mac80211 didn't see all the beacons it actually wanted to see. This caused lost associations. Hopefully we can revisit this when mac80211 is less greedy about seeing beacons directly... This reverts commit 063279062a8c530cc90fb77797db16c49c905b26. Signed-off-by: John W.

2008-11-06[WATCHDOG] SAM9 watchdog - update for moved headersAndrew Victor
The architecture header files were recently moved from include/asm-arm/mach-at91/ to arch/arm/mach-at91/include/mach/. The SAM9 watchdog driver still includes a header from the old location.

2008-11-06md: linear: Fix a division by zero bug for very small arrays.Andre Noll
We currently oops with a divide error on starting a linear software raid array consisting of at least two very small (< 500K) devices. The bug is caused by the calculation of the hash table size which tries to compute sector_div(sz, base) with "base" being zero due to the small size of the component devices of the array. Fix this by requiring the hash spacing to be at least one which implies that also "base" is non-zero. This bug has existed since about 2.6.14.

2008-11-06md: fix bug in raid10 recovery.NeilBrown
Adding a spare to a raid10 doesn't cause recovery to start. This is due to an silly type in commit 6c2fce2ef6b4821c21b5c42c7207cb9cf8c87eda and so is a bug in 2.6.27 and .28-rc. Thanks to Thomas Backlund for bisecting to find this. Cc: Thomas Backlund <tmb@mandriva.org> Cc: stable@kernel.org Signed-off-by: NeilBrown <neilb@suse.de>
2008-11-06md: revert the recent addition of a call to the BLKRRPART ioctl.NeilBrown
It turns out that it is only safe to call blkdev_ioctl when the device is actually open (as ->bd_disk is set to NULL on last close). And it is quite possible for do_md_stop to be called when the device is not open. So discard the call to blkdev_ioctl(BLKRRPART) which was added in commit 934d9c23b4c7e31840a895ba4b7e88d6413c81f3 It is just as easy to call this ioctl from userspace when needed (on mdadm -S) so leave it out of the kernel Signed-off-by: NeilBrown <neilb@suse.de>
