Pull SCSI scatter-gather list updates from James Bottomley: "This topic branch covers a fundamental change in how our sg lists are allocated to make mq more efficient by reducing the size of the preallocated sg list. This necessitates a large number of driver changes because the previous guarantee that if a driver specified SG_ALL as the size of its scatter list, it would get a non-chained list and didn't need to bother with scatterlist iterators is now broken and every driver *must* use scatterlist iterators.

2019-07-11Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsiLinus Torvalds
Pull SCSI updates from James Bottomley: "This is mostly update of the usual drivers: qla2xxx, hpsa, lpfc, ufs, mpt3sas, ibmvscsi, megaraid_sas, bnx2fc and hisi_sas as well as the removal of the osst driver (I heard from Willem privately that he would like the driver removed because all his test hardware has failed). Plus number of minor changes, spelling fixes and other trivia. The big merge conflict this time around is the SPDX licence tags. Following discussion on linux-next, we believe our version to be more accurate than the one in the tree, so the resolution is to take our version for all the SPDX conflicts" Note on the SPDX license tag conversion conflicts: the SCSI tree had done its own SPDX conversion, which in some cases conflicted with the treewide ones done by Thomas & co. In almost all cases, the conflicts were purely syntactic: the SCSI tree used the old-style SPDX tags ("GPL-2.0" and "GPL-2.0+") while the treewide conversion had used the new-style ones ("GPL-2.0-only" and "GPL-2.0-or-later"). In these cases I picked the new-style one. In a few cases, the SPDX conversion was actually different, though. As explained by James above, and in more detail in a pre-pull-request thread: "The other problem is actually substantive: In the libsas code Luben Tuikov originally specified gpl 2.0 only by dint of stating: * This file is licensed under GPLv2. In all the libsas files, but then muddied the water by quoting GPLv2 verbatim (which includes the or later than language). So for these files Christoph did the conversion to v2 only SPDX tags and Thomas converted to v2 or later tags" So in those cases, where the spdx tag substantially mattered, I took the SCSI tree conversion of it, but then also took the opportunity to turn the old-style "GPL-2.0" into a new-style "GPL-2.0-only" tag. Similarly, when there were whitespace differences or other differences to the comments around the copyright notices, I took the version from the SCSI tree as being the more specific conversion. Finally, in the spdx conversions that had no conflicts (because the treewide ones hadn't been done for those files), I just took the SCSI tree version as-is, even if it was old-style. The old-style conversions are perfectly valid, even if the "-only" and "-or-later" versions are perhaps more descriptive. * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (185 commits) scsi: qla2xxx: move IO flush to the front of NVME rport unregistration scsi: qla2xxx: Fix NVME cmd and LS cmd timeout race condition scsi: qla2xxx: on session delete, return nvme cmd scsi: qla2xxx: Fix kernel crash after disconnecting NVMe devices scsi: megaraid_sas: Update driver version to 07.710.06.00-rc1 scsi: megaraid_sas: Introduce various Aero performance modes scsi: megaraid_sas: Use high IOPS queues based on IO workload scsi: megaraid_sas: Set affinity for high IOPS reply queues scsi: megaraid_sas: Enable coalescing for high IOPS queues scsi: megaraid_sas: Add support for High IOPS queues scsi: megaraid_sas: Add support for MPI toolbox commands scsi: megaraid_sas: Offload Aero RAID5/6 division calculations to driver scsi: megaraid_sas: RAID1 PCI bandwidth limit algorithm is applicable for only Ventura scsi: megaraid_sas: megaraid_sas: Add check for count returned by HOST_DEVICE_LIST DCMD scsi: megaraid_sas: Handle sequence JBOD map failure at driver level scsi: megaraid_sas: Don't send FPIO to RL Bypass queue scsi: megaraid_sas: In probe context, retry IOC INIT once if firmware is in fault scsi: megaraid_sas: Release Mutex lock before OCR in case of DCMD timeout scsi: megaraid_sas: Call disable_irq from process IRQ poll scsi: megaraid_sas: Remove few debug counters from IO path ...

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 fixes from Thomas Gleixner: "A collection of assorted fixes: - Fix for the pinned cr0/4 fallout which escaped all testing efforts because the kvm-intel module was never loaded when the kernel was compiled with CONFIG_PARAVIRT=n. The cr0/4 accessors are moved out of line and static key is now solely used in the core code and therefore can stay in the RO after init section. So the kvm-intel and other modules do not longer reference the (read only) static key which the module loader tried to update. - Prevent an infinite loop in arch_stack_walk_user() by breaking out of the loop once the return address is detected to be 0. - Prevent the int3_emulate_call() selftest from corrupting the stack when KASAN is enabled. KASASN clobbers more registers than covered by the emulated call implementation. Convert the int3_magic() selftest to a ASM function so the compiler cannot KASANify it. - Unbreak the build with old GCC versions and with the Gold linker by reverting the 'Move of _etext to the actual end of .text'. In both cases the build fails with 'Invalid absolute R_X86_64_32S relocation: _etext' - Initialize the context lock for init_mm, which was never an issue until the alternatives code started to use a temporary mm for patching. - Fix a build warning vs. the LOWMEM_PAGES constant where clang complains rightfully about a signed integer overflow in the shift operation by converting the operand to an ULL. - Adjust the misnamed ENDPROC() of common_spurious in the 32bit entry code" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/stacktrace: Prevent infinite loop in arch_stack_walk_user() x86/asm: Move native_write_cr0/4() out of line x86/pgtable/32: Fix LOWMEM_PAGES constant x86/alternatives: Fix int3_emulate_call() selftest stack corruption x86/entry/32: Fix ENDPROC of common_spurious Revert "x86/build: Move _etext to actual end of .text" x86/ldt: Initialize the context lock for init_mm

2019-07-11Merge tag 'clone3-v5.3' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux Pull clone3 system call from Christian Brauner: "This adds the clone3 syscall which is an extensible successor to clone after we snagged the last flag with CLONE_PIDFD during the 5.2 merge window for clone(). It cleanly supports all of the flags from clone() and thus all legacy workloads. There are few user visible differences between clone3 and clone. First, CLONE_DETACHED will cause EINVAL with clone3 so we can reuse this flag. Second, the CSIGNAL flag is deprecated and will cause EINVAL to be reported. It is superseeded by a dedicated "exit_signal" argument in struct clone_args thus freeing up even more flags. And third, clone3 gives CLONE_PIDFD a dedicated return argument in struct clone_args instead of abusing CLONE_PARENT_SETTID's parent_tidptr argument. The clone3 uapi is designed to be easy to handle on 32- and 64 bit: /* uapi */ struct clone_args { __aligned_u64 flags; __aligned_u64 pidfd; __aligned_u64 child_tid; __aligned_u64 parent_tid; __aligned_u64 exit_signal; __aligned_u64 stack; __aligned_u64 stack_size; __aligned_u64 tls; }; and a separate kernel struct is used that uses proper kernel typing: /* kernel internal */ struct kernel_clone_args { u64 flags; int __user *pidfd; int __user *child_tid; int __user *parent_tid; int exit_signal; unsigned long stack; unsigned long stack_size; unsigned long tls; }; The system call comes with a size argument which enables the kernel to detect what version of clone_args userspace is passing in. clone3 validates that any additional bytes a given kernel does not know about are set to zero and that the size never exceeds a page. A nice feature is that this patchset allowed us to cleanup and simplify various core kernel codepaths in kernel/fork.c by making the internal _do_fork() function take struct kernel_clone_args even for legacy clone(). This patch also unblocks the time namespace patchset which wants to introduce a new CLONE_TIMENS flag. Note, that clone3 has only been wired up for x86{_32,64}, arm{64}, and xtensa. These were the architectures that did not require special massaging. Other architectures treat fork-like system calls individually and after some back and forth neither Arnd nor I felt confident that we dared to add clone3 unconditionally to all architectures. We agreed to leave this up to individual architecture maintainers. This is why there's an additional patch that introduces __ARCH_WANT_SYS_CLONE3 which any architecture can set once it has implemented support for clone3. The patch also adds a cond_syscall(clone3) for architectures such as nios2 or h8300 that generate their syscall table by simply including asm-generic/unistd.h. The hope is to get rid of __ARCH_WANT_SYS_CLONE3 and cond_syscall() rather soon" * tag 'clone3-v5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: arch: handle arches who do not yet define clone3 arch: wire-up clone3() syscall fork: add clone3

git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux Pull pidfd updates from Christian Brauner: "This adds two main features. - First, it adds polling support for pidfds. This allows process managers to know when a (non-parent) process dies in a race-free way. The notification mechanism used follows the same logic that is currently used when the parent of a task is notified of a child's death. With this patchset it is possible to put pidfds in an {e}poll loop and get reliable notifications for process (i.e. thread-group) exit. - The second feature compliments the first one by making it possible to retrieve pollable pidfds for processes that were not created using CLONE_PIDFD. A lot of processes get created with traditional PID-based calls such as fork() or clone() (without CLONE_PIDFD). For these processes a caller can currently not create a pollable pidfd. This is a problem for Android's low memory killer (LMK) and service managers such as systemd. Both patchsets are accompanied by selftests. It's perhaps worth noting that the work done so far and the work done in this branch for pidfd_open() and polling support do already see some adoption: - Android is in the process of backporting this work to all their LTS kernels [1] - Service managers make use of pidfd_send_signal but will need to wait until we enable waiting on pidfds for full adoption. - And projects I maintain make use of both pidfd_send_signal and CLONE_PIDFD [2] and will use polling support and pidfd_open() too" [1] https://android-review.googlesource.com/q/topic:%22pidfd+polling+support+4.9+backport%22 https://android-review.googlesource.com/q/topic:%22pidfd+polling+support+4.14+backport%22 https://android-review.googlesource.com/q/topic:%22pidfd+polling+support+4.19+backport%22 [2] https://github.com/lxc/lxc/blob/aab6e3eb73c343231cdde775db938994fc6f2803/src/lxc/start.c#L1753 * tag 'pidfd-updates-v5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: tests: add pidfd_open() tests arch: wire-up pidfd_open() pid: add pidfd_open() pidfd: add polling selftests pidfd: add polling support

2019-07-10x86/asm: Move native_write_cr0/4() out of lineThomas Gleixner
The pinning of sensitive CR0 and CR4 bits caused a boot crash when loading the kvm_intel module on a kernel compiled with CONFIG_PARAVIRT=n. The reason is that the static key which controls the pinning is marked RO after init. The kvm_intel module contains a CR4 write which requires to update the static key entry list. That obviously does not work when the key is in a RO section. With CONFIG_PARAVIRT enabled this does not happen because the CR4 write uses the paravirt indirection and the actual write function is built in. As the key is intended to be immutable after init, move native_write_cr0/4() out of line. While at it consolidate the update of the cr4 shadow variable and store the value right away when the pinning is initialized on a booting CPU. No point in reading it back 20 instructions later. This allows to confine the static key and the pinning variable to cpu/common and allows to mark them static.

Just like we do for all other block drivers. Especially as the limit imposed at the moment might be way to pessimistic for iommus. This also means we are not going to set a bounce limit for the queue, in case we have a dma mask. On most architectures it was never needed, the major hold out was x86-32 with PAE, but that has been fixed by now.

2019-07-10dt-binding: mmc: rename tmio_mmc.txt to renesas,sdhi.txtMasahiro Yamada
As commit b6147490e6aa ("mmc: tmio: split core functionality, DMA and MFD glue") said, these MMC controllers use the IP from Panasonic. TMIO (Toshiba Mobile IO) MMC was the first upstreamed user of this IP. The common driver code was split and expanded as 'tmio-mmc-core', then it became historical misnomer since 'tmio' is not the name of this IP. In the discussion [1], we decide to keep this name as-is at least in Linux driver level because renaming everything is a big churn. However, DT should not be oriented to a particular project even though it is mainly developed in Linux communities. This is the misfortune only in Linux. Let's stop exporting it to other projects, where there is no good reason to call this hardware "TMIO". Rename the file to renesas,sdhi.txt. In fact, all the information in this file is specific to the Renesas platform. This commit also removes the first paragraph entirely. The DT-binding should describe the hardware. It is strange to talk about Linux driver internals such as how the drivers are probed, how platform data are handed off, etc. [1] https://www.spinics.net/lists/linux-mmc/msg46952.html Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Simon Horman <horms+renesas@verge.net.au> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>

For Spreadtrum SD host controller, we can not use standard SD registers to change and detect the I/O voltage signals, since our voltage regulator for I/O is fixed in hardware, and no signals were connected to the SD controller. Thus add Spreadtrum specific voltage switch ops to change voltage instead of using standard SD host registers.
