2013-01-25drm/exynos: consider DMA_NONE flag to dmabuf importInki Dae1-14/+11
This patch considers DMA_NONE flag for other drivers not using dma mapping framework with iommu such as 3d gpu driver or others. For example, there might be 3d gpu driver that has its own iommu hw unit and iommu table mapping mechnism. So in this case, the dmabuf buffer imported into this driver needs just only sg table to map the buffer with its own iommu table itself. So this patch makes dma_buf_map_attachment ignore dma_map_sg call and just return sg table containing pages if dma_data_direction is DMA_NONE.

2013-01-25drm/exynos: free sg object if dma_map_sg is failedInki Dae1-0/+1
This patch releases sgt's sg object allocated by sgt_alloc_table correctly. When exynos_gem_map_dma_buf was called by dma_buf_map_attachmemt(), the sgt's sg object was allocated by sg_alloc_tale() so if dma_map_sg() is failed, the sg object should be released.

There's no need to allocate edid twice and do a memcpy when drm helpers exist to do just that. This patch cleans that interaction up, and doesn't keep the edid hanging around in the connector. v4: - removed error check for drm_mode_connector_update_edid_property which is expected to fail for Virtual Connectors like VIDI.

2013-01-24[media] radio: set vfl_dir correctly to fix modulator regressionHans Verkuil4-0/+13
The vfl_dir field should be set to indicate whether a device can receive data, output data or can do both. This is used to let the v4l core know which ioctls should be accepted and which can be refused. Unfortunately, when this field was added the radio modulator drivers were not updated: radio modulators transmit and so vfl_dir should be set to VFL_DIR_TX (or VFL_DIR_M2M in the special case of wl128x). Because of this omission it is not possible to call g/s_modulator for these drivers, which effectively renders them useless. This patch sets the correct vfl_dir value for these drivers, correcting this bug. Thanks to Paul Grinberg for bringing this to my attention.

2013-01-24usb: Using correct way to clear usb3.0 device's remote wakeup feature.Lan Tianyu2-18/+58
Usb3.0 device defines function remote wakeup which is only for interface recipient rather than device recipient. This is different with usb2.0 device's remote wakeup feature which is defined for device recipient. According usb3.0 spec 9.4.5, the function remote wakeup can be modified by the SetFeature() requests using the FUNCTION_SUSPEND feature selector. This patch is to use correct way to disable usb3.0 device's function remote wakeup after suspend error and resuming. This should be backported to kernels as old as 3.4, that contain the commit 623bef9e03a60adc623b09673297ca7a1cdfb367 "USB/xhci: Enable remote wakeup for USB3 devices."

2013-01-24xhci: Fix TD size for isochronous URBs.Sarah Sharp1-2/+3
To calculate the TD size for a particular TRB in an isoc TD, we need know the endpoint's max packet size. Isochronous endpoints also encode the number of additional service opportunities in their wMaxPacketSize field. The TD size calculation did not mask off those bits before using the field. This resulted in incorrect TD size information for isochronous TRBs when an URB frame buffer crossed a 64KB boundary. For example: - an isoc endpoint has 2 additional service opportunites and a max packet size of 1020 bytes - a frame transfer buffer contains 3060 bytes - one frame buffer crosses a 64KB boundary, and must be split into one 1276 byte TRB, and one 1784 byte TRB. The TD size is is the number of packets that remain to be transferred for a TD after processing all the max packet sized packets in the current TRB and all previous TRBs. For this TD, the number of packets to be transferred is (3060 / 1020), or 3. The first TRB contains 1276 bytes, which means it contains one full packet, and a 256 byte remainder. After processing all the max packet-sized packets in the first TRB, the host will have 2 packets left to transfer. The old code would calculate the TD size for the first TRB as: total packet count = DIV_ROUND_UP (TD length / endpoint wMaxPacketSize) total packet count - (first TRB length / endpoint wMaxPacketSize) The math should have been: total packet count = DIV_ROUND_UP (3060 / 1020) = 3 3 - (1276 / 1020) = 2 Since the old code didn't mask off the additional service interval bits from the wMaxPacketSize field, the math ended up as total packet count = DIV_ROUND_UP (3060 / 5116) = 1 1 - (1276 / 5116) = 1 Fix this by masking off the number of additional service opportunities in the wMaxPacketSize field. This patch should be backported to stable kernels as old as 3.0, that contain the commit 4da6e6f247a2601ab9f1e63424e4d944ed4124f3 "xhci 1.0: Update TD size field format." It may not apply well to kernels older than 3.2 because of commit 29cc88979a8818cd8c5019426e945aed118b400e "USB: use usb_endpoint_maxp() instead of le16_to_cpu()".

2013-01-24xhci: Fix isoc TD encoding.Sarah Sharp1-1/+3
An isochronous TD is comprised of one isochronous TRB chained to zero or more normal TRBs. Only the isoc TRB has the TBC and TLBPC fields. The normal TRBs must set those fields to zeroes. The code was setting the TBC and TLBPC fields for both isoc and normal TRBs. Fix this. This should be backported to stable kernels as old as 3.0, that contain the commit b61d378f2da41c748aba6ca19d77e1e1c02bcea5 " xhci 1.0: Set transfer burst last packet count field."

2013-01-24Btrfs: fix repeated delalloc work allocationMiao Xie1-14/+41
btrfs_start_delalloc_inodes() locks the delalloc_inodes list, fetches the first inode, unlocks the list, triggers btrfs_alloc_delalloc_work/ btrfs_queue_worker for this inode, and then it locks the list, checks the head of the list again. But because we don't delete the first inode that it deals with before, it will fetch the same inode. As a result, this function allocates a huge amount of btrfs_delalloc_work structures, and OOM happens. Fix this problem by splice this delalloc list.

2013-01-24Btrfs: fix missed transaction->aborted checkMiao Xie1-0/+16
First, though the current transaction->aborted check can stop the commit early and avoid unnecessary operations, it is too early, and some transaction handles don't end, those handles may set transaction->aborted after the check. Second, when we commit the transaction, we will wake up some worker threads to flush the space cache and inode cache. Those threads also allocate some transaction handles and may set transaction->aborted if some serious error happens. So we need more check for ->aborted when committing the transaction. Fix it.

2013-01-24Btrfs: put csums on the right ordered extentJosef Bacik1-2/+2
I noticed a WARN_ON going off when adding csums because we were going over the amount of csum bytes that should have been allowed for an ordered extent. This is a leftover from when we used to hold the csums privately for direct io, but now we use the normal ordered sum stuff so we need to make sure and check if we've moved on to another extent so that the csums are added to the right extent. Without this we could end up with csums for bytenrs that don't have extents to cover them yet. Thanks, Signed-off-by: Josef Bacik <[email protected]>

2013-01-24Btrfs: fix panic when recovering tree logJosef Bacik1-8/+12
A user reported a BUG_ON(ret) that occured during tree log replay. Ret was -EAGAIN, so what I think happened is that we removed an extent that covered a bitmap entry and an extent entry. We remove the part from the bitmap and return -EAGAIN and then search for the next piece we want to remove, which happens to be an entire extent entry, so we just free the sucker and return. The problem is ret is still set to -EAGAIN so we trip the BUG_ON(). The user used btrfs-zero-log so I'm not 100% sure this is what happened so I've added a WARN_ON() to catch the other possibility.

2013-01-24Btrfs: do not allow logged extents to be merged or removedJosef Bacik3-3/+16

2013-01-24x86/msr: Add capabilities checkAlan Cox1-0/+3
At the moment the MSR driver only relies upon file system checks. This means that anything as root with any capability set can write to MSRs. Historically that wasn't very interesting but on modern processors the MSRs are such that writing to them provides several ways to execute arbitary code in kernel space. Sample code and documentation on doing this is circulating and MSR attacks are used on Windows 64bit rootkits already. In the Linux case you still need to be able to open the device file so the impact is fairly limited and reduces the security of some capability and security model based systems down towards that of a generic "root owns the box" setup. Therefore they should require CAP_SYS_RAWIO to prevent an elevation of capabilities. The impact of this is fairly minimal on most setups because they don't have heavy use of capabilities. Those using SELinux, SMACK or AppArmor rules might want to consider if their rulesets on the MSR driver could be tighter.

2013-01-24arch/x86/tools/insn_sanity.c: Identify source of messagesAndrew Morton1-2/+8
The kernel build prints: Building modules, stage 2. TEST posttest MODPOST 3821 modules TEST posttest Success: decoded and checked 1000000 random instructions with 0 errors (seed:0xaac4bc47) CC arch/x86/boot/a20.o CC arch/x86/boot/cmdline.o AS arch/x86/boot/copy.o HOSTCC arch/x86/boot/mkcpustr CC arch/x86/boot/cpucheck.o CC arch/x86/boot/early_serial_console.o which is irritating because you don't know what program is proudly pronouncing its success. So, as described in "console mode programming user interface guidelines version 101" which doesn't exist, change this program to identify the source of its messages.

We do a: sprintf(buf, " Last beacon: %ums ago", elapsed_jiffies_msecs(bss->ts)); elapsed_jiffies_msecs() can return a 10 digit number so "buf" needs to be 31 characters long. Signed-off-by: Dan Carpenter <[email protected]> Signed-off-by: Johannes Berg <[email protected]>

The DSP bit mask for the RDDSP and WRDSP instructions was wrong. [[email protected]: The mask field of the RDDSP and WRDSP instructions is 10 bits long. DSP_MASK had all these fields which according to the architecture specification may result in UNPREDICTABLE operation.] Signed-off-by: Steven J.

2013-01-24mfd: vexpress-sysreg: Don't skip initialization on probePawel Moll1-12/+20
The vexpress-sysreg driver does not have to be initialized early, when the platform doesn't require this. Unfortunately in such case it wasn't initialized correctly - master site lookup and config bridge registration were missing. Fixed now. Signed-off-by: Pawel Moll <[email protected]>
2013-01-24ARM: vexpress: Enable A7 cores in V2P-CA15_A7's Device TreePawel Moll1-2/+0
As the kernel is able to cope with multiple clusters, uncomment the A7 cores in the Device Tree for V2P-CA15_A7 tile, making all 5 cores available to the user. Signed-off-by: Pawel Moll <[email protected]>
2013-01-24ARM: vexpress: extend the MPIDR range used for pen release checkLorenzo Pieralisi1-1/+1
In ARM multi-cluster systems the MPIDR affinity level 0 cannot be used as a single cpu identifier, affinity levels 1 and 2 must be taken into account as well. This patch extends the MPIDR usage to affinity levels 1 and 2 in versatile secondary cores start up code in order to compare the passed pen_release value with the full-blown affinity mask.

2013-01-24regulator: tps65910: Fix using wrong dev argument for calling of_regulator_matchAxel Lin1-1/+1
The dev parameter is the device requesting the data. In this case it should be &pdev->dev rather than pdev->dev.parent. The dev parameter is used to call devm_kzalloc in of_get_regulator_init_data(), which means this fixes a memory leak because the memory is allocated every time probe() is called, thus it should be freed when this driver is unloaded.
