2012-03-26mtd: ST SPEAr: Add SMI driver for serial NOR flashShiraz Hashim
SPEAr platforms (spear3xx/spear6xx/spear13xx) provide SMI (Serial Memory Interface) controller to access serial NOR flash. SMI provides a simple interface for SPI/serial NOR flashes and has certain inbuilt commands and features to support these flashes easily. It also makes it possible to map an address range in order to directly access (read/write) the SNOR over address bus. This patch intends to provide serial nor driver support for spear platforms which are accessed through SMI.

2012-03-26mtd: nand: differentiate 1- vs. 2-byte writes when marking bad blocksBrian Norris
It seems that we have developed a bad-block-marking "feature" out of pure laziness: "We write two bytes per location, so we dont have to mess with 16 bit access." It's relatively simple to write a 1 byte at a time on x8 devices and 2 bytes at a time on x16 devices, so let's do it.

2012-03-26mtd: nand: erase block before marking badBrian Norris
Many NAND flash systems (especially those with MLC NAND) cannot be reliably written twice in a row. For instance, when marking a bad block, the block may already have data written to it, and so we should attempt to erase the block before writing a bad block marker to its OOB region. We can ignore erase failures, since the block may be bad such that it cannot be erased properly; we still attempt to write zeros to its spare area.

2012-03-02hwmon: (f75375s) Catch some attempts to write to r/o registersNikolaus Schulz
It makes no sense to attempt to manually configure the fan in auto mode, or set the duty cycle directly in closed loop mode. The corresponding registers are then read-only.

2012-03-02hwmon: (f75375s) Properly map the F75387 automatic modes to pwm_enableNikolaus Schulz
The F75387 supports automatic fan control using either PWM duty cycle or RPM speed values. Make the driver detect the latter mode, and expose the different modes in sysfs as per pwm_enable, so that the user can switch between them. The interpretation of the pwm_enable attribute for the F75387 is adjusted to be a superset of those values used for similar Fintek chips which do not support automatic duty mode, with 2 mapping to automatic speed mode, and moving automatic duty mode to the new value 4. Toggling the duty mode via pwm_enable is currently denied for the F75387, as the chip then simply reinterprets the fan configuration register values according to the new mode, switching between RPM and PWM units, which makes this a dangerous operation. This patch introduces a new pwm mode into the driver. This is necessary because the new mode (automatic pwm mode, 4) may already be enabled by the BIOS, and the driver should not break existing functionality. This was seen on at least one board.

2012-02-29virtio: balloon: leak / fill balloon across S4Amit Shah
commit e562966dbaf49e7804097cd991e5d3a8934fc148 added support for S4 to the balloon driver. The freeze function did nothing to free the pages, since reclaiming the pages from the host to immediately give them back (if S4 was successful) seemed wasteful. Also, if S4 wasn't successful, the guest would have to re-fill the balloon. On restore, the pages were supposed to be marked freed and the free page counters were incremented to reflect the balloon was totally deflated. However, this wasn't done right. The pages that were earlier taken away from the guest during a balloon inflation operation were just shown as used pages after a successful restore from S4. Just a fancy way of leaking lots of memory. Instead of trying that, just leak the balloon on freeze and fill it on restore/thaw paths. This works properly now. The optimisation to not leak can be added later on after a bit of refactoring of the code. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2012-02-29OMAPDSS: APPLY: make ovl_enable/disable synchronousTomi Valkeinen
ovl->enable/disable are meant to be synchronous so that they can handle the configuration of fifo sizes. The current kernel doesn't configure fifo sizes yet, and so the code doesn't need to block to function (from omapdss driver's perspective). However, for the users of omapdss a non-blocking ovl->disable is confusing, because they don't know when the memory area is not used any more. Furthermore, when the fifo size configuration is added in the next merge window, the change from non-blocking to blocking could cause side effects to the users of omapdss. So by making the functions block already will keep them behaving in the same manner. And, while not the main purpose of this patch, this will also remove the compile warning: drivers/video/omap2/dss/apply.c:350: warning: 'wait_pending_extra_info_updates' defined but not used Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>

2012-02-27drm/i915: Remove use of the autoreported ringbuffer HEAD positionChris Wilson
This is a revert of 6aa56062eaba67adfb247cded244fd877329588d. This was originally introduced to workaround reads of the ringbuffer registers returning 0 on SandyBridge causing hangs due to ringbuffer overflow. The root cause here was reads through the GT powerwell require the forcewake dance, something we only learnt of later. Now it appears that reading the reported head position from the HWS is returning garbage, leading once again to hangs. For example, on q35 the autoreported head reports: [ 217.975608] head now 00010000, actual 00010000 [ 436.725613] head now 00200000, actual 00200000 [ 462.956033] head now 00210000, actual 00210010 [ 485.501409] head now 00400000, actual 00400020 [ 508.064280] head now 00410000, actual 00410000 [ 530.576078] head now 00600000, actual 00600020 [ 553.273489] head now 00610000, actual 00610018 which appears reasonably sane. In contrast, if we look at snb: [ 141.970680] head now 00e10000, actual 00008238 [ 141.974062] head now 02734000, actual 000083c8 [ 141.974425] head now 00e10000, actual 00008488 [ 141.980374] head now 032b5000, actual 000088b8 [ 141.980885] head now 03271000, actual 00008950 [ 142.040628] head now 02101000, actual 00008b40 [ 142.180173] head now 02734000, actual 00009050 [ 142.181090] head now 00000000, actual 00000ae0 [ 142.183737] head now 02734000, actual 00009050 In addition, the automatic reporting of the head position is scheduled to be defeatured in the future. It has no more utility, remove it.

omap3isp depends on omap's iommu and will fail to probe if initialized before it (which always happen if they are builtin). Make omap's iommu subsys_initcall as an interim solution until the probe deferral mechanism is merged.

I anticipate some TX side locking fixes coming in the near future for this driver as well. 6) The inline directive fix in Bluetooth which was breaking the build only with very new versions of GCC, from Johan Hedberg. 7) Fix crashes in the ATP CLIP code due to ARP cleanups this merge window, reported by Meelis Roos and fixed by Eric Dumazet. 8) JME driver doesn't flush RX FIFO correctly, from Guo-Fu Tseng. 9) Some ip6_route_output() callers test the return value for NULL, but this never happens as the convention is to return a dst entry with dst->error set. Fixes from RonQing Li. 10) Logitech Harmony 900 should be handled by zaurus driver not cdc_ether, update white lists and black lists accordingly. From Scott Talbert. 11) Receiving from certain kinds of devices there won't be a MAC header, so there is no MAC header to fixup in the IPSEC code, and if we try to do it we'll crash. Fix from Eric Dumazet. 12) Port type array indexing off-by-one in mlx4 driver, fix from Yevgeny Petrilin. 13) Fix regression in link-down handling in davinci_emac which causes all RX descriptors to be freed up and therefore RX to wedge completely, from Christian Riesch. 14) It took two attempts, but ctnetlink soft lockups seem to be cured now, from Pablo Neira Ayuso. 15) Endianness bug fix in ENIC driver, from Santosh Nayak. 16) The long ago conversion of the PPP fragmentation code over to abstracted SKB list handling wasn't perfect, once we get an out of sequence SKB we don't flush the rest of them like we should. From Ben McKeegan. 17) Fix regression of ->ip_summed initialization in sfc driver. From Ben Hutchings. 18) Bluetooth timeout mistakenly using msecs instead of jiffies, from Andrzej Kaczmarek. 19) Using _sync variant of work cancellation results in deadlocks, use the non _sync variants instead. From Andre Guedes. 20) Bluetooth rfcomm code had reference counting problems leading to crashes, fix from Octavian Purdila. 21) The conversion of netem over to classful qdisc handling added two bugs to netem_dequeue(), fixes from Eric Dumazet. 22) Missing pci_iounmap() in ATM Solos driver. Fix from Julia Lawall. 23) b44_pci_exit() should not have __exit tag since it's invoked from non-__exit code. From Nikola Pajkovsky. 24) The conversion of the neighbour hash tables over to RCU added a race, fixed here by adding the necessary reread of tbl->nht, fix from Michel Machado. 25) When we added VF (virtual function) attributes for network device dumps, this potentially bloats up the size of the dump of one network device such that the dump size is too large for the buffer allocated by properly written netlink applications. In particular, if you add 255 VFs to a network device, parts of GLIBC stop working. To fix this, we add an attribute that is used to turn on these extended portions of the network device dump. Sophisticaed applications like 'ip' that want to see this stuff will be changed to set the attribute, whereas things like GLIBC that don't care about VFs simply will not, and therefore won't be busted by the mere presence of VFs on a network device. Thanks to the tireless work of Greg Rose on this fix. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (53 commits) sfc: Fix assignment of ip_summed for pre-allocated skbs ppp: fix 'ppp_mp_reconstruct bad seq' errors enic: Fix endianness bug. gre: fix spelling in comments netfilter: ctnetlink: fix soft lockup when netlink adds new entries (v2) Revert "netfilter: ctnetlink: fix soft lockup when netlink adds new entries" davinci_emac: Do not free all rx dma descriptors during init mlx4_core: Fixing array indexes when setting port types phy: IC+101G and PHY_HAS_INTERRUPT flag netdev/phy/icplus: Correct broken phy_init code ipsec: be careful of non existing mac headers Move Logitech Harmony 900 from cdc_ether to zaurus hso: memsetting wrong data in hso_get_count() netfilter: ip6_route_output() never returns NULL. ethernet/broadcom: ip6_route_output() never returns NULL. ipv6: ip6_route_output() never returns NULL. jme: Fix FIFO flush issue atm: clip: remove clip_tbl ipv4: ping: Fix recvmsg MSG_OOB error handling. rtnetlink: Fix problem with buffer allocation ...

2012-02-25[SCSI] osd_uld: Bump MAX_OSD_DEVICES from 64 to 1,048,576Boaz Harrosh
It used to be that minors where 8 bit. But now they are actually 20 bit. So the fix is simplicity itself. I've tested with 300 devices and all user-mode utils work just fine. I have also mechanically added 10,000 to the ida (so devices are /dev/osd10000, /dev/osd10001 ...) and was able to mkfs an exofs filesystem and access osds from user-mode. All the open-osd user-mode code uses the same library to access devices through their symbolic names in /dev/osdX so I'd say it's pretty safe. (Well tested) This patch is very important because some of the systems that will be deploying the 3.2 pnfs-objects code are larger than 64 OSDs and will stop to work properly when reaching that number.
