2014-09-18drm/i915: Add limited color range readout for HDMI/DP ports on g4x/vlv/chvVille Syrjälä2-1/+10
The limited color range knob is in the port registers on g4x and vlv/chv for HDMI, and on g4x for DP. Add the relevant code to read out the hardware state into pipe config. On vlv/chv the DP port limited color range knob is in PIPECONF for which we already have readout code.

2014-09-17iscsi-target: avoid NULL pointer in iscsi_copy_param_list failureJoern Engel1-1/+1
In iscsi_copy_param_list() a failed iscsi_param_list memory allocation currently invokes iscsi_release_param_list() to cleanup, and will promptly trigger a NULL pointer dereference. Instead, go ahead and return for the first iscsi_copy_param_list() failure case. Found by coverity.

2014-09-17Revert "init: make rootdelay=N consistent with rootwait behaviour"Paul Gortmaker1-6/+6
This reverts commit 4dfe694f616e00e6fd83e5bbcd7a3c4d7113493d. In that, we did: Here we move the rootdelay code to be right beside the rootwait code, so that their behaviour is consistent. ...which is fine, but in hindsight, perhaps moving the rootwait to be beside the rootdelay would have been better. We also indicated: It should be noted that in doing so, the actions based on the saved_root_name[0] and initrd_load() were previously put on hold by rootdelay=N and now currently will not be delayed. However, I think consistent behaviour is more important than matching historical behaviour of delaying the above two operations. But Pavel reported an instance where an ARM target with root on MMC was failing to mount root, and Russell diagnosed it to the fact that the call to set ROOT_DEV within the saved_root_name[0] processing block mentioned above was no longer being delayed. Rather than moving both wait clauses to the original position of rootdelay and risking unearthing other possible corner case breakage at this point in time, we simply revert now and we can revisit trying the alternate/earlier location in another development cycle.

2014-09-17MIPS: SmartMIPS: Disable assembler warningsMarkos Chandras1-1/+10
The kernel code overrides the default ISA as passed by the compiler in quite a few places. This has unfortunate side effects when smartmips is enabled leading to hundreds of warnings during build such as: {standard input}: Assembler messages: {standard input}:411: Warning: the `smartmips' extension requires MIPS32 revision 1 or greater {standard input}: Assembler messages: {standard input}:43: Warning: the 64-bit MIPS architecture does not support the `smartmips' extension [...] Until the kernel code is fixed properly (if possible), disable all the assembler warning messages to make the build logs readable again. This has no runtime side effects but it makes it easier to spot more critical warnings and problems during build.

2014-09-16Btrfs: set inode's logged_trans/last_log_commit after ranged fsyncFilipe Manana2-14/+13
When a ranged fsync finishes if there are still extent maps in the modified list, still set the inode's logged_trans and last_log_commit. This is important in case an inode is fsync'ed and unlinked in the same transaction, to ensure its inode ref gets deleted from the log and the respective dentries in its parent are deleted too from the log (if the parent directory was fsync'ed in the same transaction). Instead make btrfs_inode_in_log() return false if the list of modified extent maps isn't empty. This is an incremental on top of the v4 version of the patch: "Btrfs: fix fsync data loss after a ranged fsync" which was added to its v5, but didn't make it on time.

2014-09-16vgaarb: Don't default exclusively to first video device with mem+ioBruno Prémont3-47/+39
Commit 20cde694027e ("x86, ia64: Move EFI_FB vga_default_device() initialization to pci_vga_fixup()") moved boot video device detection from efifb to x86 and ia64 pci/fixup.c. For dual-GPU Apple computers above change represents a regression as code in efifb did forcefully override vga_default_device while the merge did not (vgaarb happens prior to PCI fixup). To improve on initial device selection by vgaarb (it cannot know if PCI device not behind bridges see/decode legacy VGA I/O or not), move the screen_info based check from pci_video_fixup() to vgaarb's init function and use it to refine/override decision taken while adding the individual PCI VGA devices. This way PCI fixup has no reason to adjust vga_default_device anymore but can depend on its value for flagging shadowed VBIOS. This has the nice benefit of removing duplicated code but does introduce a #if defined() block in vgaarb. Not all architectures have screen_info and would cause compile to fail without it.

2014-09-15iscsi-target: Ignore ICF_GOT_LAST_DATAOUT during Data-Out ITT lookupNicholas Bellinger1-0/+2
This patch adds a explicit check in iscsit_find_cmd_from_itt_or_dump() to ignore commands with ICF_GOT_LAST_DATAOUT set. This is done to address the case where an ITT is being reused for DataOUT, but the previous command with the same ITT has not yet been acknowledged by ExpStatSN and removed from the per connection command list. This issue was originally manifesting itself by referencing the previous command during ITT lookup, and subsequently hitting the check in iscsit_check_dataout_hdr() for ICF_GOT_LAST_DATAOUT, that resulted in the DataOUT PDU + associated payload being silently dumped.

2014-09-15vfs: simplify and shrink stack frame of link_path_walk()Linus Torvalds1-21/+18
Commit 9226b5b440f2 ("vfs: avoid non-forwarding large load after small store in path lookup") made link_path_walk() always access the "hash_len" field as a single 64-bit entity, in order to avoid mixed size accesses to the members. However, what I didn't notice was that that effectively means that the whole "struct qstr this" is now basically redundant. We already explicitly track the "const char *name", and if we just use "u64 hash_len" instead of "long len", there is nothing else left of the "struct qstr". We do end up wanting the "struct qstr" if we have a filesystem with a "d_hash()" function, but that's a rare case, and we might as well then just squirrell away the name and hash_len at that point. End result: fewer live variables in the loop, a smaller stack frame, and better code generation. And we don't need to pass in pointers variables to helper functions any more, because the return value contains all the relevant information. So this removes more lines than it adds, and the source code is clearer too. Signed-off-by: Linus Torvalds <[email protected]>

2014-09-14vfs: avoid non-forwarding large load after small store in path lookupLinus Torvalds2-9/+11
The performance regression that Josef Bacik reported in the pathname lookup (see commit 99d263d4c5b2 "vfs: fix bad hashing of dentries") made me look at performance stability of the dcache code, just to verify that the problem was actually fixed. That turned up a few other problems in this area. There are a few cases where we exit RCU lookup mode and go to the slow serializing case when we shouldn't, Al has fixed those and they'll come in with the next VFS pull. But my performance verification also shows that link_path_walk() turns out to have a very unfortunate 32-bit store of the length and hash of the name we look up, followed by a 64-bit read of the combined hash_len field. That screws up the processor store to load forwarding, causing an unnecessary hickup in this critical routine. It's caused by the ugly calling convention for the "hash_name()" function, and easily fixed by just making hash_name() fill in the whole 'struct qstr' rather than passing it a pointer to just the hash value. With that, the profile for this function looks much smoother. Signed-off-by: Linus Torvalds <[email protected]>

2014-09-14iio: adc: at91: don't use the last converted data registerLudovic Desroches1-5/+7
If touchscreen mode is enabled and a conversion is requested on another channel, the result in the last converted data register can be a touchscreen relative value. Starting a conversion involves to do a conversion for all active channel. It starts with ADC channels and ends with touchscreen channels. Then if ADC_LCD register is not read quickly, its content may be a touchscreen conversion. To remove this temporal constraint, the conversion value is taken from the channel data register.
