Biggest changes are from a batch of OMAP bugfixes, but there are a few for the broader set of SoCs too (bcm2835, pxa, highbank, tegra, at91 and i.MX). The OMAP patches contain some fixes for MUSB/PHY on omap4 which ends up being a bit on the large side but needed for legacy (non-DT) platforms. Beyond that there are a handful of hwmod/pm changes.

2012-11-16Drivers: hv: Add Hyper-V balloon driverK. Y. Srinivasan3-0/+1048
Add the basic balloon driver. Windows hosts dynamically manage the guest memory allocation via a combination memory hot add and ballooning. Memory hot add is used to grow the guest memory upto the maximum memory that can be allocatted to the guest. Ballooning is used to both shrink as well as expand up to the max memory. Supporting hot add needs additional support from the host. We will support hot add when this support is available. For now, by setting the VM startup memory to the VM max memory, we can use ballooning alone to dynamically manage memory allocation amongst competing guests on a given host. Signed-off-by: K. Y.

It will be useful to be able to access global memory commitment from device drivers. On the Hyper-V platform, the host has a policy engine to balance the available physical memory amongst all competing virtual machines hosted on a given node. This policy engine is driven by a number of metrics including the memory commitment reported by the guests. The balloon driver for Linux on Hyper-V will use this function to retrieve guest memory commitment. This function is also used in Xen self ballooning code.

2012-11-15s390/3215: fix tty close handlingHeiko Carstens1-7/+5
The 3215 console always has the RAW3215_FIXED flag set, which causes raw3215_shutdown() not to wait for outstanding I/O requests if an attached tty gets closed. The flag however can be simply removed, so we can guarantee that all requests belonging to the tty have been processed when the tty is closed. However the tasklet that belongs to the 3215 device may be scheduled even if there is no tty attached anymore, since we have a race between console and tty processing. Thefore unconditional tty_wakekup() in raw3215_wakeup() can cause the following NULL pointer dereference: 3.465368 Unable to handle kernel pointer dereference at virtual kernel address (null) 3.465448 Oops: 0004 #1 SMP 3.465454 Modules linked in: 3.465459 CPU: 1 Not tainted 3.6.0 #1 3.465462 Process swapper/1 (pid: 0, task: 000000003ffa4428, ksp: 000000003ffb7ce0) 3.465466 Krnl PSW : 0404100180000000 0000000000162f86 (__wake_up+0x46/0xb8) 3.465480 R:0 T:1 IO:0 EX:0 Key:0 M:1 W:0 P:0 AS:0 CC:1 PM:0 EA:3 Krnl GPRS: fffffffffffffffe 0000000000000000 0000000000000160 0000000000000001 3.465492 0000000000000001 0000000000000004 0000000000000004 000000000096b490 3.465499 0000000000000001 0000000000000100 0000000000000001 0000000000000001 3.465506 070000003fc87d60 0000000000000160 000000003fc87d68 000000003fc87d00 3.465526 Krnl Code: 0000000000162f76: e3c0f0a80004 lg %r12,168(%r15) 0000000000162f7c: 58000370 l %r0,880 #0000000000162f80: c007ffffffff00 xilf %r0,4294967295 >0000000000162f86: ba102000 cs %r1,%r0,0(%r2) 0000000000162f8a: 1211 ltr %r1,%r1 0000000000162f8c: a774002f brc 7,162fea 0000000000162f90: b904002d lgr %r2,%r13 0000000000162f94: b904003a lgr %r3,%r10 3.465597 Call Trace: 3.465599 (<0400000000000000> 0x400000000000000) 3.465602 <000000000048c77e> raw3215_wakeup+0x2e/0x40 3.465607 <0000000000134d66> tasklet_action+0x96/0x168 3.465612 <000000000013423c> __do_softirq+0xd8/0x21c 3.465615 <0000000000134678> irq_exit+0xa8/0xac 3.465617 <000000000046c232> do_IRQ+0x182/0x248 3.465621 <00000000005c8296> io_return+0x0/0x8 3.465625 <00000000005c7cac> vtime_stop_cpu+0x4c/0xb8 3.465629 (<0000000000194e06> tick_nohz_idle_enter+0x4e/0x74) 3.465633 <0000000000104760> cpu_idle+0x170/0x184 3.465636 <00000000005b5182> smp_start_secondary+0xd6/0xe0 3.465641 <00000000005c86be> restart_int_handler+0x56/0x6c 3.465643 <0000000000000000> 0x0 3.465645 Last Breaking-Event-Address: 3.465647 <0000000000403136> tty_wakeup+0x46/0x98 3.465652 3.465654 Kernel panic - not syncing: Fatal exception in interrupt 01: HCPGIR450W CP entered; disabled wait PSW 00020001 80000000 00000000 0010F63C The easiest solution is simply to check if tty is NULL in the tasklet.

2012-11-15Revert "drivers/net/phy/mdio-bitbang.c: Call mdiobus_unregister before ↵David S. Miller1-1/+0
mdiobus_free" This reverts commit aa731872f7d33dcb8b54dad0cfb82d4e4d195d7e. As pointed out by Ben Hutchings, this change is not correct. mdiobus_unregister() can't be called if the bus isn't registered yet, however this change can result in situations which cause that to happen. Part of the confusion here revolves around the fact that the callers of this module control registration/unregistration, rather than the module itself. Signed-off-by: David S.

2012-11-15net/smsc911x: Fix ready check in cases where WORD_SWAP is neededKamlakant Patel1-2/+15
The chip ready check added by the commit 3ac3546e [Always wait for the chip to be ready] does not work when the register read/write is word swapped. This check has been added before the WORD_SWAP register is programmed, so we need to check for swapped register value as well. Bit 16 is marked as RESERVED in SMSC datasheet, Steve Glendinning <steve@shawell.net> checked with SMSC and wrote: The chip architects have concluded we should be reading PMT_CTRL until we see any of bits 0, 8, 16 or 24 set. Then we should read BYTE_TEST to check the byte order is correct (as we already do). The rationale behind this is that some of the chip variants have word order swapping features too, so the READY bit could actually be in any of the 4 possible locations. The architects have confirmed that if any of these 4 positions is set the chip is ready. The other 3 locations will either never be set or can only go high after READY does (so also indicate the device is ready). This change will check for the READY bit at the 16th position. We do not check the other two cases (bit 8 and 24) since the driver does not support byte-swapped register read/write.

2012-11-15drivers/net: fix tasklet misuse issueXiaotian Feng3-38/+18
In commit 175c0dff, drivers uses tasklet_kill to avoid put disabled tasklet on the tasklet vec. But some of the drivers uses tasklet_init & tasklet_disable in the driver init code, then tasklet_enable when it is opened. This makes tasklet_enable on a killed tasklet and make ksoftirqd crazy then. Normally, drivers should use tasklet_init/tasklet_kill on device open/remove, and use tasklet_disable/tasklet_enable on device suspend/resume.
