2019-08-18nvmem: imx: add i.MX8QM platform supportFugang Duan1-0/+7

2019-08-18nvmem: meson-mx-efuse: allow reading data smaller than word_sizeMartin Blumenstingl1-1/+2
Some Amlogic boards store the Ethernet MAC address inside the eFuse. The Ethernet MAC address uses 6 bytes. The existing logic in meson_mx_efuse_read() would write beyond the end of the data buffer when trying to read data with a size that is not aligned to word_size (4 bytes on Meson8, Meson8b and Meson8m2). Calculate the remaining data to copy inside meson_mx_efuse_read() so reading 6 bytes doesn't write beyond the end of the data buffer.

Each iteration of for_each_available_child_of_node puts the previous node, but in the case of a return from the middle of the loop, there is no put, thus causing a memory leak. Hence add an of_node_put before the return in two places. Issue found with Coccinelle.

2019-08-15sgi-xpc: Use GFP_ATOMIC for kmalloc in atomic context.Fuqian Huang1-1/+1
xpc_send_activate_IRQ_uv is called from <-xpc_send_activate_IRQ_part_uv <-xpc_indicate_partition_disengaged_uv (xpc_arch_ops.indicate_partition_disengaged) <-xpc_die_deactivate <-xpc_system_die xpc_system_die is registered by atomic_notifier_chain_register, which indicates xpc_system_die may be called in atomic context.

2019-08-15misc: xilinx_sdfec: Support poll file operationDragan Cvetic1-4/+236
Support monitoring and detecting the SD-FEC error events through IRQ and poll file operation. The SD-FEC device can detect one-error or multi-error events. An error triggers an interrupt which creates and run the ONE_SHOT IRQ thread. The ONE_SHOT IRQ thread detects type of error and pass that information to the poll function. The file_operation callback poll(), collects the events and updates the statistics accordingly. The function poll blocks() on waiting queue which can be unblocked by ONE_SHOT IRQ handling thread. Support SD-FEC interrupt set ioctl callback. The SD-FEC can detect two type of errors: coding errors (ECC) and a data interface errors (TLAST). The errors are events which can trigger an IRQ if enabled. The driver can monitor and detect these errors through IRQ. Also the driver updates the statistical data.

2019-08-09bcache: Revert "bcache: use sysfs_match_string() instead of __sysfs_match_string()"Coly Li1-8/+12
This reverts commit 89e0341af082dbc170019f908846f4a424efc86b. In drivers/md/bcache/sysfs.c:bch_snprint_string_list(), NULL pointer at the end of list is necessary. Remove the NULL from last element of each lists will cause the following panic, [ 4340.455652] bcache: register_cache() registered cache device nvme0n1 [ 4340.464603] bcache: register_bdev() registered backing device sdk [ 4421.587335] bcache: bch_cached_dev_run() cached dev sdk is running already [ 4421.587348] bcache: bch_cached_dev_attach() Caching sdk as bcache0 on set 354e1d46-d99f-4d8b-870b-078b80dc88a6 [ 5139.247950] general protection fault: 0000 [#1] SMP NOPTI [ 5139.247970] CPU: 9 PID: 5896 Comm: cat Not tainted 4.12.14-95.29-default #1 SLE12-SP4 [ 5139.247988] Hardware name: HPE ProLiant DL380 Gen10/ProLiant DL380 Gen10, BIOS U30 04/18/2019 [ 5139.248006] task: ffff888fb25c0b00 task.stack: ffff9bbacc704000 [ 5139.248021] RIP: 0010:string+0x21/0x70 [ 5139.248030] RSP: 0018:ffff9bbacc707bf0 EFLAGS: 00010286 [ 5139.248043] RAX: ffffffffa7e432e3 RBX: ffff8881c20da02a RCX: ffff0a00ffffff04 [ 5139.248058] RDX: 3f00656863616362 RSI: ffff8881c20db000 RDI: ffffffffffffffff [ 5139.248075] RBP: ffff8881c20db000 R08: 0000000000000000 R09: ffff8881c20da02a [ 5139.248090] R10: 0000000000000004 R11: 0000000000000000 R12: ffff9bbacc707c48 [ 5139.248104] R13: 0000000000000fd6 R14: ffffffffc0665855 R15: ffffffffc0665855 [ 5139.248119] FS: 00007faf253b8700(0000) GS:ffff88903f840000(0000) knlGS:0000000000000000 [ 5139.248137] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 5139.248149] CR2: 00007faf25395008 CR3: 0000000f72150006 CR4: 00000000007606e0 [ 5139.248164] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 5139.248179] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 [ 5139.248193] PKRU: 55555554 [ 5139.248200] Call Trace: [ 5139.248210] vsnprintf+0x1fb/0x510 [ 5139.248221] snprintf+0x39/0x40 [ 5139.248238] bch_snprint_string_list.constprop.15+0x5b/0x90 [bcache] [ 5139.248256] __bch_cached_dev_show+0x44d/0x5f0 [bcache] [ 5139.248270] ? __alloc_pages_nodemask+0xb2/0x210 [ 5139.248284] bch_cached_dev_show+0x2c/0x50 [bcache] [ 5139.248297] sysfs_kf_seq_show+0xbb/0x190 [ 5139.248308] seq_read+0xfc/0x3c0 [ 5139.248317] __vfs_read+0x26/0x140 [ 5139.248327] vfs_read+0x87/0x130 [ 5139.248336] SyS_read+0x42/0x90 [ 5139.248346] do_syscall_64+0x74/0x160 [ 5139.248358] entry_SYSCALL_64_after_hwframe+0x3d/0xa2 [ 5139.248370] RIP: 0033:0x7faf24eea370 [ 5139.248379] RSP: 002b:00007fff82d03f38 EFLAGS: 00000246 ORIG_RAX: 0000000000000000 [ 5139.248395] RAX: ffffffffffffffda RBX: 0000000000020000 RCX: 00007faf24eea370 [ 5139.248411] RDX: 0000000000020000 RSI: 00007faf25396000 RDI: 0000000000000003 [ 5139.248426] RBP: 00007faf25396000 R08: 00000000ffffffff R09: 0000000000000000 [ 5139.248441] R10: 000000007c9d4d41 R11: 0000000000000246 R12: 00007faf25396000 [ 5139.248456] R13: 0000000000000003 R14: 0000000000000000 R15: 0000000000000fff [ 5139.248892] Code: ff ff ff 0f 1f 80 00 00 00 00 49 89 f9 48 89 cf 48 c7 c0 e3 32 e4 a7 48 c1 ff 30 48 81 fa ff 0f 00 00 48 0f 46 d0 48 85 ff 74 45 <44> 0f b6 02 48 8d 42 01 45 84 c0 74 38 48 01 fa 4c 89 cf eb 0e The simplest way to fix is to revert commit 89e0341af082 ("bcache: use sysfs_match_string() instead of __sysfs_match_string()"). This bug was introduced in Linux v5.2, so this fix only applies to Linux v5.2 is enough for stable tree maintainer.
