2020-03-30mfd: rk808: Stop using syscore opsRobin Murphy
Setting the SLEEP pin to its shutdown function for appropriate PMICs doesn't need to happen in single-CPU context, so there's really no point involving the syscore machinery. Hook it up to the standard driver model shutdown method instead. This also obviates the issue that the syscore ops weren't being unregistered on probe failure or module removal.

2020-03-30mfd: rk808: Ensure suspend/resume hooks always workRobin Murphy
The RK809/RK817 suspend/resume hooks should not have to depend on whether this driver owns the pm_power_off hook, and thus the global rk808_i2c_client is set - indeed, the GPIO-based control is really only relevant when PSCI firmware is in charge of power rather than the kernel. As driver model callbacks, they have an appropriate device argument to hand, so can just always use that.

2020-03-30mfd: rk808: Always use poweroff when requestedSoeren Moch
With the device tree property "rockchip,system-power-controller" we explicitly request to use this PMIC to power off the system. So always register our poweroff function, even if some other handler (probably PSCI poweroff) was registered before. This does tend to reveal a warning on shutdown due to the Rockchip I2C driver not implementing an atomic transfer method, however since the write to DEV_OFF takes effect immediately the I2C completion interrupt is moot anyway, and as the very last thing written to the console it is only visible to users going out of their way to capture serial output.

2020-03-30mfd: pm8xxx: Replace zero-length array with flexible-array memberGustavo A. R. Silva
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

2020-03-29mlx4: fix "initializer element not constant" compiler errorJacob Keller
A recent commit e8937681797c ("devlink: prepare to support region operations") used the region_cr_space_str and region_fw_health_str variables as initializers for the devlink_region_ops structures. This can result in compiler errors: drivers/net/ethernet/mellanox//mlx4/crdump.c:45:10: error: initializer element is not constant .name = region_cr_space_str, ^ drivers/net/ethernet/mellanox//mlx4/crdump.c:45:10: note: (near initialization for ‘region_cr_space_ops.name’) drivers/net/ethernet/mellanox//mlx4/crdump.c:50:10: error: initializer element is not constant .name = region_fw_health_str, The variables were made to be "const char * const", indicating that both the pointer and data were constant. This was enough to resolve this on recent GCC (gcc (GCC) 9.2.1 20190827 (Red Hat 9.2.1-1) for this author). Unfortunately this is not enough for older compilers to realize that the variable can be treated as a constant expression. Fix this by introducing macros for the string and use those instead of the variable name in the region ops structures.

2020-03-30crypto: caam - simplify RNG implementationAndrey Smirnov
Rework CAAM RNG implementation as follows: - Make use of the fact that HWRNG supports partial reads and will handle such cases gracefully by removing recursion in caam_read() - Convert blocking caam_read() codepath to do a single blocking job read directly into requested buffer, bypassing any intermediary buffers - Convert async caam_read() codepath into a simple single reader/single writer FIFO use-case, thus simplifying concurrency handling and delegating buffer read/write position management to KFIFO subsystem. - Leverage the same low level RNG data extraction code for both async and blocking caam_read() scenarios, get rid of the shared job descriptor and make non-shared one as a simple as possible (just HEADER + ALGORITHM OPERATION + FIFO STORE) - Split private context from DMA related memory, so that the former could be allocated without GFP_DMA. NOTE: On its face value this commit decreased throughput numbers reported by dd if=/dev/hwrng of=/dev/null bs=1 count=100K [iflag=nonblock] by about 15%, however commits that enable prediction resistance and limit JR total size impact the performance so much and move the bottleneck such as to make this regression irrelevant. NOTE: On the bright side, this commit reduces RNG in kernel DMA buffer memory usage from 2 x RN_BUF_SIZE (~256K) to 32K.

2020-03-29scsi: target: avoid per-loop XCOPY buffer allocationsDavid Disseldorp
The main target_xcopy_do_work() loop unnecessarily allocates an I/O buffer with each synchronous READ / WRITE pair. This commit significantly reduces allocations by reusing the XCOPY I/O buffer when possible.

2020-03-29scsi: target: drop xcopy DISK BLOCK LENGTH debugDavid Disseldorp
The DISK BLOCK LENGTH field is carried with XCOPY target descriptors on the wire, but is currently unmarshalled during 0x02 segment descriptor passing. The unmarshalled value is currently unused, so drop it.

2020-03-29scsi: ufs-mediatek: add error recovery for suspend and resumeStanley Chu
Once fail happens during suspend and resume flow if the desired low power link state is H8, link recovery is required for MediaTek UFS controller. For resume flow, since power and clocks are already enabled before invoking vendor's resume callback, simply using ufshcd_link_recovery() inside callback is fine. For suspend flow, the device power enters low power mode or is disabled before suspend callback, thus ufshcd_link_recovery() can not be directly used in vendor callback. One solution is to set the link to off state and then ufshcd_host_reset_and_restore() will be executed by ufshcd_suspend().

2020-03-29scsi: ufs: Clean up ufshcd_scale_clks() and clock scaling error out pathSubhash Jadavani
This change introduces a func ufshcd_set_clk_freq() to explicitly set clock frequency so that it can be used in reset_and_restore path and in ufshcd_scale_clks(). This change also cleans up the clock scaling error out path.

2020-03-29scsi: lpfc: Fix erroneous cpu limit of 128 on I/O statisticsJames Smart
The cpu io statistics were capped by a hard define limit of 128. This effectively was a max number of CPUs, not an actual CPU count, nor actual CPU numbers which can be even larger than both of those values. This made stats off/misleading and on large CPU count systems, wrong. Fix the stats so that all CPUs can have a stats struct. Fix the looping such that it loops by hdwq, finds CPUs that used the hdwq, and sum the stats, then display.
