2020-10-08spi: dw: Detach SPI device specific CR0 config methodSerge Semin
Indeed there is no point in detecting the SPI peripheral device parameters and initializing the CR0 register fields each time an SPI transfer is executed. Instead let's define a dedicated CR0 chip-data member, which will be initialized in accordance with the SPI device settings at the moment of setting it up. By doing so we'll finally make the SPI device chip_data serving as it's supposed to - to preserve the SPI device specific DW SPI configuration. See spi-fsl-dspi.c, spi-pl022.c, spi-pxa2xx.c drivers for example of the way the chip data is utilized.

2020-10-08spi: dw: Add DWC SSI capabilitySerge Semin
Currently DWC SSI core is supported by means of setting up the core-specific update_cr0() callback. It isn't suitable for multiple reasons. First of all having exported several methods doing the same thing but for different chips makes the code harder to maintain. Secondly the spi-dw-core driver exports the methods, then the spi-dw-mmio driver sets the private data callback with one of them so to be called by the core driver again. That makes the code logic too complicated. Thirdly using callbacks for just updating the CR0 register is problematic, since in case if the register needed to be updated from different parts of the code, we'd have to create another callback (for instance the SPI device-specific parameters don't need to be calculated each time the SPI transfer is submitted, so it's better to pre-calculate the CR0 data at the SPI-device setup stage). So keeping all the above in mind let's discard the update_cr0() callbacks, define a generic and static dw_spi_update_cr0() method and create the DW_SPI_CAP_DWC_SSI capability, which when enabled would activate the alternative CR0 register layout. While at it add the comments to the code path of the normal DW APB SSI controller setup to make the dw_spi_update_cr0() method looking coherent.

2020-10-08spi: dw: Use an explicit set_cs assignmentSerge Semin

Use kstrndup() to copy line labels from the userspace provided char array, rather than ensuring the char array contains a null terminator and using kstrdup(). Note that the length provided to kstrndup() still assumes that the char array does contain a null terminator, so the maximum string length is one less than the array.

2020-10-08seccomp: Make duplicate listener detection non-racyJann Horn
Currently, init_listener() tries to prevent adding a filter with SECCOMP_FILTER_FLAG_NEW_LISTENER if one of the existing filters already has a listener. However, this check happens without holding any lock that would prevent another thread from concurrently installing a new filter (potentially with a listener) on top of the ones we already have. Theoretically, this is also a data race: The plain load from current->seccomp.filter can race with concurrent writes to the same location. Fix it by moving the check into the region that holds the siglock to guard against concurrent TSYNC. (The "Fixes" tag points to the commit that introduced the theoretical data race; concurrent installation of another filter with TSYNC only became possible later, in commit 51891498f2da ("seccomp: allow TSYNC and USER_NOTIF together").)

2020-10-08seccomp: Move config option SECCOMP to arch/KconfigYiFei Zhu
In order to make adding configurable features into seccomp easier, it's better to have the options at one single location, considering especially that the bulk of seccomp code is arch-independent. An quick look also show that many SECCOMP descriptions are outdated; they talk about /proc rather than prctl. As a result of moving the config option and keeping it default on, architectures arm, arm64, csky, riscv, sh, and xtensa did not have SECCOMP on by default prior to this and SECCOMP will be default in this change. Architectures microblaze, mips, powerpc, s390, sh, and sparc have an outdated depend on PROC_FS and this dependency is removed in this change.

2020-10-08ftrace: Simplify the calculation of page number for ftrace_page->recordsWei Yang
Based on the following two reasones, we could simplify the calculation: - If the number after roundup count is not power of 2, we would definitely have more than 1 empty page with a higher order. - get_count_order() just return current order, so one lower order could meet the requirement. The calculation could be simplified by lower one order level when pages are not power of 2.

2020-10-08ftrace: Simplify the dyn_ftrace->flags macroWei Yang
All the three macro are defined to be used for ftrace_rec_count(). This can be achieved by (flags & FTRACE_REF_MAX) directly. Since no other places would use those macros, remove them for clarity. Also it fixes a typo in the comment.

2020-10-08ftrace: Simplify the hash calculationSteven Rostedt (VMware)
No need to add a check to subtract the number of bits if bits is zero after fls(). Just divide the size by two before calling it. This does give the same answer for size of 0 and 1, but that's fine. Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>

2020-10-08r8169: consider that PHY reset may still be in progress after applying firmwareHeiner Kallweit
Some firmware files trigger a PHY soft reset and don't wait for it to be finished. PHY register writes directly after applying the firmware may fail or provide unexpected results therefore. Fix this by waiting for bit BMCR_RESET to be cleared after applying firmware. There's nothing wrong with the referenced change, it's just that the fix will apply cleanly only after this change.
