Pull VT-d hardware workarounds from David Woodhouse: "This contains a workaround for hardware issues which I *thought* were never going to be seen on production hardware. I'm glad I checked that before the 4.1 release... Firstly, PASID support is so broken on existing chips that we're just going to declare the old capability bit 28 as 'reserved' and change the VT-d spec to move PASID support to another bit. So any existing hardware doesn't support SVM; it only sets that (now) meaningless bit 28. That patch *wasn't* imperative for 4.1 because we don't have PASID support yet. But *even* the extended context tables are broken — if you just enable the wider tables and use none of the new bits in them, which is precisely what 4.1 does, you find that translations don't work. It's this problem which I thought was caught in time to be fixed before production, but wasn't. To avoid triggering this issue, we now *only* enable the extended context tables on hardware which also advertises "we have PASID support and we actually tested it this time" with the new PASID feature bit. In addition, I've added an 'intel_iommu=ecs_off' command line parameter to allow us to disable it manually if we need to" * git://git.infradead.org/intel-iommu: iommu/vt-d: Only enable extended context tables if PASID is supported iommu/vt-d: Change PASID support to bit 40 of Extended Capability Register
2015-06-12iommu/vt-d: Only enable extended context tables if PASID is supportedDavid Woodhouse
Although the extended tables are theoretically a completely orthogonal feature to PASID and anything else that *uses* the newly-available bits, some of the early hardware has problems even when all we do is enable them and use only the same bits that were in the old context tables. For now, there's no motivation to support extended tables unless we're going to use PASID support to do SVM. So just don't use them unless PASID support is advertised too. Also add a command-line bailout just in case later chips also have issues. The equivalent problem for PASID support has already been fixed with the upcoming VT-d spec update and commit bd00c606a ("iommu/vt-d: Change PASID support to bit 40 of Extended Capability Register"), because the problematic platforms use the old definition of the PASID-capable bit, which is now marked as reserved and meaningless. So with this change, we'll magically start using ECS again only when we see the new hardware advertising "hey, we have PASID support and we actually tested it this time" on bit 40. The VT-d hardware architect has promised that we are not going to have any reason to support ECS *without* PASID any time soon, and he'll make sure he checks with us before changing that. In the future, if hypothetical new features also use new bits in the context tables and can be seen on implementations *without* PASID support, we might need to add their feature bits to the ecs_enabled() macro.

2015-05-15Documentation: dt: mtd: replace "nor-jedec" binding with "jedec, spi-nor"Brian Norris
In commit 8ff16cf77ce3 ("Documentation: devicetree: m25p80: add "nor-jedec" binding"), we added a generic "nor-jedec" binding to catch all mostly-compatible SPI NOR flash which can be detected via the READ ID opcode (0x9F). This was discussed and reviewed at the time, however objections have come up since then as part of this discussion: http://lkml.kernel.org/g/20150511224646.GJ32500@ld-irv-0074 It seems the parties involved agree that "jedec,spi-nor" does a better job of capturing the fact that this is SPI-specific, not just any NOR flash. This binding was only merged for v4.1-rc1, so it's still OK to change the naming. At the same time, let's move the documentation to a better name. Next up: stop referring to code (drivers/mtd/devices/m25p80.c) from the documentation.

2015-05-10pty: Fix input race when closingPeter Hurley
A read() from a pty master may mistakenly indicate EOF (errno == -EIO) after the pty slave has closed, even though input data remains to be read. For example, pty slave | input worker | pty master | | | | n_tty_read() pty_write() | | input avail? no add data | | sleep schedule worker --->| | . |---> flush_to_ldisc() | . pty_close() | fill read buffer | . wait for worker | wakeup reader --->| . | read buffer full? |---> input avail ? yes |<--- yes - exit worker | copy 4096 bytes to user TTY_OTHER_CLOSED <---| |<--- kick worker | | **** New read() before worker starts **** | | n_tty_read() | | input avail? no | | TTY_OTHER_CLOSED? yes | | return -EIO Several conditions are required to trigger this race: 1. the ldisc read buffer must become full so the input worker exits 2. the read() count parameter must be >= 4096 so the ldisc read buffer is empty 3. the subsequent read() occurs before the kicked worker has processed more input However, the underlying cause of the race is that data is pipelined, while tty state is not; ie., data already written by the pty slave end is not yet visible to the pty master end, but state changes by the pty slave end are visible to the pty master end immediately. Pipeline the TTY_OTHER_CLOSED state through input worker to the reader. 1. Introduce TTY_OTHER_DONE which is set by the input worker when TTY_OTHER_CLOSED is set and either the input buffers are flushed or input processing has completed. Readers/polls are woken when TTY_OTHER_DONE is set. 2. Reader/poll checks TTY_OTHER_DONE instead of TTY_OTHER_CLOSED. 3. A new input worker is started from pty_close() after setting TTY_OTHER_CLOSED, which ensures the TTY_OTHER_DONE state will be set if the last input worker is already finished (or just about to exit). Remove tty_flush_to_ldisc(); no in-tree callers.

2015-05-04bus: omap_l3_noc: Fix master id address decoding for OMAP5Suman Anna
The L3 Error handling on OMAP5 for the most part is very similar to that of OMAP4, and had leveraged common data structures and register layout definitions so far. Upon closer inspection, there are a few minor differences causing an incorrect decoding and reporting of the master NIU upon an error: 1. The L3_TARG_STDERRLOG_MSTADDR.STDERRLOG_MSTADDR occupies 11 bits on OMAP5 as against 8 bits on OMAP4, with the master NIU connID encoded in the 6 MSBs of the STDERRLOG_MSTADDR field. 2. The CLK3 FlagMux component has 1 input source on OMAP4 and 3 input sources on OMAP5. The common DEBUGSS source is at a different input on each SoC. Fix the above issues by using a OMAP5-specific compatible property and using SoC-specific data where there are differences.

2015-05-02target/user: Disallow full passthrough (pass_level=0)Andy Grover
TCMU requires more work to correctly handle both user handlers that want all SCSI commands (pass_level=0) for a se_device, and also handlers that just want I/O commands and let the others be emulated by the kernel (pass_level=1). Only support the latter for now. For full passthrough, we will need to support a second se_subsystem_api template, due to configfs attributes being different between the two modes. Thus pass_level is extraneous, and we can remove it. The ABI break for TCMU v2 is already applied for this release, so it's best to do this now to avoid another ABI break in the future.
