commit 9756fe38d10b2bf90c81dc4d2f17d5632e135364 upstream. This box claims to have an LVDS interface but doesn't actually have one.

2012-10-31staging: comedi: amplc_pc236: fix invalid register access during detachIan Abbott
commit aaeb61a97b7159ebe30b18a422d04eeabfa8790b upstream. `pc236_detach()` is called by the comedi core if it attempted to attach a device and failed. `pc236_detach()` calls `pc236_intr_disable()` if the comedi device private data pointer (`devpriv`) is non-null. This test is insufficient as `pc236_intr_disable()` accesses hardware registers and the attach routine may have failed before it has saved their I/O base addresses. Fix it by checking `dev->iobase` is non-zero before calling `pc236_intr_disable()` as that means the I/O base addresses have been saved and the hardware registers can be accessed. It also implies the comedi device private data pointer is valid, so there is no need to check it.

2012-10-31xhci: Fix potential NULL ptr deref in command cancellation.Sarah Sharp
commit 43a09f7fb01fa1e091416a2aa49b6c666458c1ee upstream. The command cancellation code doesn't check whether find_trb_seg() couldn't find the segment that contains the TRB to be canceled. This could cause a NULL pointer deference later in the function when next_trb is called. It's unlikely to happen unless something is wrong with the command ring pointers, so add some debugging in case it happens. This patch should be backported to stable kernels as old as 3.0, that contain the commit b63f4053cc8aa22a98e3f9a97845afe6c15d0a0d "xHCI: handle command after aborting the command ring".

2012-10-28mtd: nand: allow NAND_NO_SUBPAGE_WRITE to be set from driverBrian Norris
commit bf7a01bf7987b63b121d572b240c132ec44129c4 upstream. The NAND_CHIPOPTIONS_MSK has limited utility and is causing real bugs. It silently masks off at least one flag that might be set by the driver (NAND_NO_SUBPAGE_WRITE). This breaks the GPMI NAND driver and possibly others. Really, as long as driver writers exercise a small amount of care with NAND_* options, this mask is not necessary at all; it was only here to prevent certain options from accidentally being set by the driver. But the original thought turns out to be a bad idea occasionally. Thus, kill it. Note, this patch fixes some major gpmi-nand breakage.

[ Upstream commit a2af139ff1cd85df586690ff626619ab1ee88b0a ] Marvell 88E8001 on an ASUS P5NSLI motherboard is unable to send/receive packets on a system with >4gb ram unless a 32bit DMA mask is used. This issue has been around for years and a fix was sent 3.5 years ago, but there was some debate as to whether it should instead be fixed as a PCI quirk. http://www.spinics.net/lists/netdev/msg88670.html However, 18 months later a similar workaround was introduced for another chipset exhibiting the same problem. http://www.spinics.net/lists/netdev/msg142287.html Signed-off-by: Graham Gower <graham.gower@gmail.com> Signed-off-by: Jan Ceuleers <jan.ceuleers@computer.org> Acked-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.

commit 041d81f493d90c940ec41f0ec98bc7c4f2fba431 upstream. If a USB transfer has already been started, meaning we have already issued StartTransfer command to that particular endpoint, DWC3_EP_BUSY flag has also already been set. When we try to cancel this transfer which is already in controller's cache, we will not receive XferComplete event and we must clear DWC3_EP_BUSY in order to allow subsequent requests to be properly started. The best place to clear that flag is right after issuing DWC3_DEPCMD_ENDTRANSFER.

2012-10-21tpm: Propagate error from tpm_transmit to fix a timeout hangPeter Huewe
commit abce9ac292e13da367bbd22c1f7669f988d931ac upstream. tpm_write calls tpm_transmit without checking the return value and assigns the return value unconditionally to chip->pending_data, even if it's an error value. This causes three bugs. So if we write to /dev/tpm0 with a tpm_param_size bigger than TPM_BUFSIZE=0x1000 (e.g. 0x100a) and a bufsize also bigger than TPM_BUFSIZE (e.g. 0x100a) tpm_transmit returns -E2BIG which is assigned to chip->pending_data as -7, but tpm_write returns that TPM_BUFSIZE bytes have been successfully been written to the TPM, altough this is not true (bug #1). As we did write more than than TPM_BUFSIZE bytes but tpm_write reports that only TPM_BUFSIZE bytes have been written the vfs tries to write the remaining bytes (in this case 10 bytes) to the tpm device driver via tpm_write which then blocks at /* cannot perform a write until the read has cleared either via tpm_read or a user_read_timer timeout */ while (atomic_read(&chip->data_pending) != 0) msleep(TPM_TIMEOUT); for 60 seconds, since data_pending is -7 and nobody is able to read it (since tpm_read luckily checks if data_pending is greater than 0) (#bug 2). After that the remaining bytes are written to the TPM which are interpreted by the tpm as a normal command. (bug #3) So if the last bytes of the command stream happen to be a e.g. tpm_force_clear this gets accidentally sent to the TPM. This patch fixes all three bugs, by propagating the error code of tpm_write and returning -E2BIG if the input buffer is too big, since the response from the tpm for a truncated value is bogus anyway. Moreover it returns -EBUSY to userspace if there is a response ready to be read.

2012-10-21e1000e: Change wthresh to 1 to avoid possible Tx stallsHiroaki SHIMODA
commit 8edc0e624db3756783233e464879eb2e3b904c13 upstream. This patch originated from Hiroaki SHIMODA but has been modified by Intel with some minor cleanups and additional commit log text. Denys Fedoryshchenko and others reported Tx stalls on e1000e with BQL enabled. Issue was root caused to hardware delays. They were introduced because some of the e1000e hardware with transmit writeback bursting enabled, waits until the driver does an explict flush OR there are WTHRESH descriptors to write back. Sometimes the delays in question were on the order of seconds, causing visible lag for ssh sessions and unacceptable tx completion latency, especially for BQL enabled kernels. To avoid possible Tx stalls, change WTHRESH back to 1. The current plan is to investigate a method for re-enabling WTHRESH while not harming BQL, but those patches will be later for net-next if they work. please enqueue for stable since v3.3 as this bug was introduced in commit 3f0cfa3bc11e7f00c9994e0f469cbc0e7da7b00c Author: Tom Herbert <therbert@google.com> Date: Mon Nov 28 16:33:16 2011 +0000 e1000e: Support for byte queue limits Changes to e1000e to use byte queue limits.
