2017-12-31i2c/ARM: davinci: Deep refactoring of I2C recoveryLinus Walleij4-17/+39

2017-12-03i2c: rcar: skip DMA if buffer is not safeWolfram Sang1-1/+1
This HW is prone to races, so it needs to setup new messages in irq context. That means we can't alloc bounce buffers if a message buffer is not DMA safe. So, in that case, simply fall back to PIO.

2017-12-03i2c: sh_mobile: use core helper to decide when to use DMAWolfram Sang1-2/+6
This ensures that we fall back to PIO if the message length is too small for DMA being useful. Otherwise, we use DMA. A bounce buffer might be applied by the helper if the original message buffer is not DMA safe.

2017-12-03i2c: refactor i2c_master_{send_recv}Wolfram Sang2-50/+48
Those two functions are very similar, the only differences are that one needs the I2C_M_RD flag for its message while the other one needs the buffer casted to drop the const. Introduce a generic helper which allows to specify the flags (also needed later for DMA safe variants of these calls) and let the casting be done in the inlining functions which are now calling the new helper function.

The datasheet was a bit vague, but after consultation with HW designers, we came to the conclusion that we should set the SCP bit always when dealing only with the ICE bit. A set SCP bit is ignored, and thus fine, a cleared one may trigger STOP on the bus.

git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc fixes from Michael Ellerman: "A small batch of fixes, about 50% tagged for stable and the rest for recently merged code. There's one more fix for the >128T handling on hash. Once a process had requested a single mmap above 128T we would then always search above 128T. The correct behaviour is to consider the hint address in isolation for each mmap request. Then a couple of fixes for the IMC PMU, a missing EXPORT_SYMBOL in VAS, a fix for STRICT_KERNEL_RWX on 32-bit, and a fix to correctly identify P9 DD2.1 but in code that is currently not used by default.

git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending Pull SCSI target updates from Nicholas Bellinger: "This series is predominantly bug-fixes, with a few small improvements that have been outstanding over the last release cycle. As usual, the associated bug-fixes have CC' tags for stable. Also, things have been particularly quiet wrt new developments the last months, with most folks continuing to focus on stability atop 4.x stable kernels for their respective production configurations. Also at this point, the stable trees have been synced up with mainline. This will continue to be a priority, as production users tend to run exclusively atop stable kernels, a few releases behind mainline. The highlights include: - Fix PR PREEMPT_AND_ABORT null pointer dereference regression in v4.11+ (tangwenji) - Fix OOPs during removing TCMU device (Xiubo Li + Zhang Zhuoyu) - Add netlink command reply supported option for each device (Kenjiro Nakayama) - cxgbit: Abort the TCP connection in case of data out timeout (Varun Prakash) - Fix PR/ALUA file path truncation (David Disseldorp) - Fix double se_cmd completion during ->cmd_time_out (Mike Christie) - Fix QUEUE_FULL + SCSI task attribute handling in 4.1+ (Bryant Ly + nab) - Fix quiese during transport_write_pending_qf endless loop (nab) - Avoid early CMD_T_PRE_EXECUTE failures during ABORT_TASK in 3.14+ (Don White + nab)" * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (35 commits) tcmu: Add a missing unlock on an error path tcmu: Fix some memory corruption iscsi-target: Fix non-immediate TMR reference leak iscsi-target: Make TASK_REASSIGN use proper se_cmd->cmd_kref target: Avoid early CMD_T_PRE_EXECUTE failures during ABORT_TASK target: Fix quiese during transport_write_pending_qf endless loop target: Fix caw_sem leak in transport_generic_request_failure target: Fix QUEUE_FULL + SCSI task attribute handling iSCSI-target: Use common error handling code in iscsi_decode_text_input() target/iscsi: Detect conn_cmd_list corruption early target/iscsi: Fix a race condition in iscsit_add_reject_from_cmd() target/iscsi: Modify iscsit_do_crypto_hash_buf() prototype target/iscsi: Fix endianness in an error message target/iscsi: Use min() in iscsit_dump_data_payload() instead of open-coding it target/iscsi: Define OFFLOAD_BUF_SIZE once target: Inline transport_put_cmd() target: Suppress gcc 7 fallthrough warnings target: Move a declaration of a global variable into a header file tcmu: fix double se_cmd completion target: return SAM_STAT_TASK_SET_FULL for TCM_OUT_OF_RESOURCES ...
