2018-12-24pwm: imx: Add ipg clock operationAnson Huang
i.MX PWM module's ipg_clk_s is for PWM register access, on most of i.MX SoCs, this ipg_clk_s is from system ipg clock or perclk which is always enabled, but on i.MX7D, the ipg_clk_s is from PWM1_CLK_ROOT which is controlled by CCGR132, that means the CCGR132 MUST be enabled first before accessing PWM registers on i.MX7D. This patch adds ipg clock operation to make sure register access successfully on i.MX7D and it fixes Linux kernel boot up hang during PWM driver probe.

2018-12-23CIFS: Fix error mapping for SMB2_LOCK command which caused OFD lock problemGeorgy A Bystrenin
While resolving a bug with locks on samba shares found a strange behavior. When a file locked by one node and we trying to lock it from another node it fail with errno 5 (EIO) but in that case errno must be set to (EACCES | EAGAIN). This isn't happening when we try to lock file second time on same node. In this case it returns EACCES as expected. Also this issue not reproduces when we use SMB1 protocol (vers=1.0 in mount options). Further investigation showed that the mapping from status_to_posix_error is different for SMB1 and SMB2+ implementations. For SMB1 mapping is [NT_STATUS_LOCK_NOT_GRANTED to ERRlock] (See fs/cifs/netmisc.c line 66) but for SMB2+ mapping is [STATUS_LOCK_NOT_GRANTED to -EIO] (see fs/cifs/smb2maperror.c line 383) Quick changes in SMB2+ mapping from EIO to EACCES has fixed issue.

2018-12-23MIPS: ralink: Select CONFIG_CPU_MIPSR2_IRQ_VI on MT7620/8Stefan Roese
Testing has shown, that when using mainline U-Boot on MT7688 based boards, the system may hang or crash while mounting the root-fs. The main issue here is that mainline U-Boot configures EBase to a value near the end of system memory. And with CONFIG_CPU_MIPSR2_IRQ_VI disabled, trap_init() will not allocate a new area to place the exception handler. The original value will be used and the handler will be copied to this location, which might already be used by some userspace application. The MT7688 supports VI - its config3 register is 0x00002420, so VInt (Bit 5) is set. But without setting CONFIG_CPU_MIPSR2_IRQ_VI this bit will not be evaluated to result in "cpu_has_vi" being set. This patch now selects CONFIG_CPU_MIPSR2_IRQ_VI on MT7620/8 which results trap_init() to allocate some memory for the exception handler. Please note that this issue was not seen with the Mediatek U-Boot version, as it does not touch EBase (stays at default of 0x8000.0000). This is strictly also not correct as the kernel (_text) resides here.

No algorithms are registered with this type anymore, so it's unneeded. - The "const char *geniv" member of aead_alg, ablkcipher_alg, and blkcipher_alg. A few algorithms still set this, but it isn't used anymore except to show via /proc/crypto and CRYPTO_MSG_GETALG.
