2017-06-28ALSA: Fix forgotten dependency fix for tristate OSS sequencer kconfigTakashi Iwai
In the commit 3d774d5ef066 ("ALSA: seq: Allow the tristate build of OSS emulation") we changed CONFIG_SND_SEQUENCER_OSS to tristate, but a couple of places were forgotten, namely, opl3 and emux Makefile. These contain the line like snd-opl3-synth-$(CONFIG_SND_SEQUENCER_OSS) += opl3_oss.o and this doesn't work any longer as expected because snd-opl3-synth can be built-in while CONFIG_SND_SEQUENCER_OSS=m. This patch fixes these places to build properly for the new kconfig dependency. In the end, we had to use ifneq() to satisfy the requirement. It's a bit ugly, but lesser evil.

2017-06-28s390/dasd: Fix faulty ENODEV for RO sysfs attributeJan Höppner
If a device is offline it can still be set to read-only via the bus id through sysfs. Only the read-only feature flag for the ccw_device is then set. If the device is online the corresponding block device needs to be set to read-only as well (via set_disk_ro()). The check whether there is a device to do so, however, happens after the feature flag was set. This leads to an unnecessary "no such device" error in the offline case. This bug was introduced by commit 7571cb1c8e3cc ("s390/dasd: Make use of dasd_set_feature() more often"). Fix this by simply returning count if no device is available.

2017-06-28s390/pci: recognize name clashes with uidsSebastian Ott
When uid checking is enabled firmware guarantees uniqueness of the uids and we use them for device enumeration. Tests have shown that uid checking can be toggled at runtime.

2017-06-28s390/pci: improve error handling during interrupt deregistrationSebastian Ott
When we ask a function to stop creating interrupts this may fail due to the function being already gone (e.g. after hot-unplug). Consequently we don't free associated resources like summary bits and bit vectors used for irq processing. This could lead to situations where we ran out of these resources and fail to setup new interrupts. The fix is to just ignore the errors in cases where we can be sure no new interrupts are generated.

2017-06-28ALSA: hda - set input_path bitmap to zero after moving it to new placeHui Wang
Recently we met a problem, the codec has valid adcs and input pins, and they can form valid input paths, but the driver does not build valid controls for them like "Mic boost", "Capture Volume" and "Capture Switch". Through debugging, I found the driver needs to shrink the invalid adcs and input paths for this machine, so it will move the whole column bitmap value to the previous column, after moving it, the driver forgets to set the original column bitmap value to zero, as a result, the driver will invalidate the path whose index value is the original colume bitmap value. After executing this function, all valid input paths are invalidated by a mistake, there are no any valid input paths, so the driver won't build controls for them.

2017-06-28powerpc/fadump: add reschedule point while releasing memoryHari Bathini
Around 95% of memory is reserved by fadump/capture kernel. All this memory is freed, one page at a time, on writing '1' to the node /sys/kernel/fadump_release_mem. On systems with large memory, this can take a long time to complete, leading to soft lockup warning messages. To avoid this, add reschedule points at regular intervals. Also, while memblock_reserve() implicitly takes care of holes in the given memory range while reserving memory, those holes need to be taken care of while releasing memory as memory is freed one page at a time. Add support to skip holes while releasing memory.

2017-06-28powerpc/fadump: avoid holes in boot memory area when fadump is registeredHari Bathini
To register fadump, boot memory area - the size of low memory chunk that is required for a kernel to boot successfully when booted with restricted memory, is assumed to have no holes. But this memory area is currently not protected from hot-remove operations. So, fadump could fail to re-register after a memory hot-remove operation, if memory is removed from boot memory area. To avoid this, ensure that memory from boot memory area is not hot-removed when fadump is registered.

2017-06-28powerpc/fadump: avoid duplicates in crash memory rangesHari Bathini
fadump sets up crash memory ranges to be used for creating PT_LOAD program headers in elfcore header. Memory chunk RMA_START through boot memory area size is added as the first memory range because firmware, at the time of crash, moves this memory chunk to different location specified during fadump registration making it necessary to create a separate program header for it with the correct offset. This memory chunk is skipped while setting up the remaining memory ranges. But currently, there is possibility that some of this memory may have duplicate entries like when it is hot-removed and added again. Ensure that no two memory ranges represent the same memory. When 5 lmbs are hot-removed and then hot-plugged before registering fadump, here is how the program headers in /proc/vmcore exported by fadump look like without this change: Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz Flags Align NOTE 0x0000000000010000 0x0000000000000000 0x0000000000000000 0x0000000000001894 0x0000000000001894 0 LOAD 0x0000000000021020 0xc000000000000000 0x0000000000000000 0x0000000040000000 0x0000000040000000 RWE 0 LOAD 0x0000000040031020 0xc000000000000000 0x0000000000000000 0x0000000010000000 0x0000000010000000 RWE 0 LOAD 0x0000000050040000 0xc000000010000000 0x0000000010000000 0x0000000050000000 0x0000000050000000 RWE 0 LOAD 0x00000000a0040000 0xc000000060000000 0x0000000060000000 0x000000019ffe0000 0x000000019ffe0000 RWE 0 and with this change: Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz Flags Align NOTE 0x0000000000010000 0x0000000000000000 0x0000000000000000 0x0000000000001894 0x0000000000001894 0 LOAD 0x0000000000021020 0xc000000000000000 0x0000000000000000 0x0000000040000000 0x0000000040000000 RWE 0 LOAD 0x0000000040030000 0xc000000040000000 0x0000000040000000 0x0000000020000000 0x0000000020000000 RWE 0 LOAD 0x0000000060030000 0xc000000060000000 0x0000000060000000 0x000000019ffe0000 0x000000019ffe0000 RWE 0 Signed-off-by: Hari Bathini <hbathini@linux.vnet.ibm.com> Reviewed-by: Mahesh J Salgaonkar <mahesh@linux.vnet.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

io_cmpl_skip keep track of number of completions to skip when stats are reset. If a fw_reset happens immediately after stats reset it could put it out of sync so need to reset io_cmpl_skip when fw reset is completed.

2017-06-27scsi: bnx2fc: Make rport_terminate_io callback a NOOP.Chad Dupuis
Do not call the stock libfc terminate rport i/o handler so we won't reset the libfc exchange manager and kill any outstanding discovery requests. Signed-off-by: Chad Dupuis <chad.dupuis@cavium.com> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>
2017-06-27scsi: bnx2fc: If IO is still in cleanup then do not return to SCSI layer.Chad Dupuis
In eh_abort, driver is calling scsi->done() for a IO for which cleanup is pending. As the IO is outstanding with the firmware, it may do DMA associated with the IO. This may lead to heap corruption. Do not complete the IO for which cleanup is still pending. Return failure from eh_abort and let the SCSI-ml retry the IO. Signed-off-by: Chad Dupuis <chad.dupuis@cavium.com> Signed-off-by: Martin K.

2017-06-27scsi: bnx2fc: Add filters to the non-offload FCoE receive path.Chad Dupuis
Add the following filters to bnx2fc_recv_frame(): 1. Filter out invalid packets - eth->dest_mac[3] matches FC frame's D_ID 2. Filter out packets that are not from our connected target - In FIP_ST_ENABLED mode - eth->src_mac matches fcoe_ctlr->dest_addr 3. Filter out packets where if d_id of the packet doesn't belong to the device when one is already assigned a port_id, only then this packet is dropped Signed-off-by: Chad Dupuis <chad.dupuis@cavium.com> Signed-off-by: Martin K.
