git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 boot updates from Ingo Molnar: "Most of the changes center around the difficult problem of KASLR pinning down hot-removable memory regions. At the very early stage KASRL is making irreversible kernel address layout decisions we don't have full knowledge about the memory maps yet. So the changes from Chao Fan add this (parsing the RSDP table early), together with fixes from Borislav Petkov" * 'x86-boot-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/boot/compressed/64: Do not read legacy ROM on EFI system x86/boot: Correct RSDP parsing with 32-bit EFI x86/kexec: Fill in acpi_rsdp_addr from the first kernel x86/boot: Fix randconfig build error due to MEMORY_HOTREMOVE x86/boot: Fix cmdline_find_option() prototype visibility x86/boot/KASLR: Limit KASLR to extract the kernel in immovable memory only x86/boot: Parse SRAT table and count immovable memory regions x86/boot: Early parse RSDP and save it in boot_params x86/boot: Search for RSDP in memory x86/boot: Search for RSDP in the EFI tables x86/boot: Add "acpi_rsdp=" early parsing x86/boot: Copy kstrtoull() to boot/string.c x86/boot: Build the command line parsing code unconditionally

git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc updates from Michael Ellerman: "Notable changes: - Enable THREAD_INFO_IN_TASK to move thread_info off the stack. - A big series from Christoph reworking our DMA code to use more of the generic infrastructure, as he said: "This series switches the powerpc port to use the generic swiotlb and noncoherent dma ops, and to use more generic code for the coherent direct mapping, as well as removing a lot of dead code." - Increase our vmalloc space to 512T with the Hash MMU on modern CPUs, allowing us to support machines with larger amounts of total RAM or distance between nodes. - Two series from Christophe, one to optimise TLB miss handlers on 6xx, and another to optimise the way STRICT_KERNEL_RWX is implemented on some 32-bit CPUs. - Support for KCOV coverage instrumentation which means we can run syzkaller and discover even more bugs in our code. And as always many clean-ups, reworks and minor fixes etc. Thanks to: Alan Modra, Alexey Kardashevskiy, Alistair Popple, Andrea Arcangeli, Andrew Donnellan, Aneesh Kumar K.V, Aravinda Prasad, Balbir Singh, Brajeswar Ghosh, Breno Leitao, Christian Lamparter, Christian Zigotzky, Christophe Leroy, Christoph Hellwig, Corentin Labbe, Daniel Axtens, David Gibson, Diana Craciun, Firoz Khan, Gustavo A.

git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux Pull RISC-V updates from Palmer Dabbelt: "This contains the vast majority of the RISC-V patches for this merge window. It includes: - A handful of cleanups to our kernel prints, most of which are things I should have caught the first time. - We now provide an HWCAP that contains the ISA extensions that all enabled processors support, as supposed to just looking at the first enabled processor. - We no longer spin forever waiting for all harts to boot. - A fixmap implementation, which is coupled to some cleanups in our MM code. The only outstanding patches I know of right now are Vincent Chen's patches to fix c.ebreak handling in the kernel, the v2 of which was posted this morning. I'd like those in the MW, but I didn't want to hold up everything else. The patch set is based on top of my last fixes submission, but I've tested it with a conflict-free merge from v5.0. I'm doing this rather than my "just go rebase everything" flow due to a discussion with Linus, but if I misunderstood then just let me know and I'll do something else. It's also the first time I've taken a PR into my own tree, so let me know if I screwed that one up. I've used my standard testing flow (QEMU in Fedora), but now that we're starting to get the kernel in better shape I think it's time to impose some more testing here -- specifically I'm going to require that patches boot on the HiFive Unleashed because we're getting to the point where we can actually expect that to work. I haven't done that for this tag, but I'm going to do it for future ones. I know the board is a bit expensive and not everyone has one, but if I've sent you a free one and your patches break the boot then I'm going to yell at you :). If you don't have one then please indicate how you tested in your cover letter, and if you have a board then please add your Tested-by to patches if they work for your testing flow" * tag 'riscv-for-linus-5.1-mw0' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux: arch: riscv: fix logic error in parse_dtb RISC-V: Assign hwcap as per comman capabilities.

Despite the rather large diffstat, most of the changes are from two bug fix patches that move code from one Kconfig option to another. Beyond that bit of churn, the remaining changes are largely cleanups and bug-fixes as we slowly march towards container auditing.

I'm testing a few small patches for my real pull request which will come at a later time. The second patch depends on your tree anyway so I included it along with the urgent fix. A small fix Pavel sent me back in august was accidentally lost due to it being placed with some other patches that failed some tests, and was rebased out of my local tree. Which was a regression that caused event filters not to handle negative numbers. The clean up is from Masami that realized that the code in kprobes that calls probe_mem_read() wrapper, which is to be used in code used by both kprobes and uprobes, was only in code for kprobes. It should not use the wrapper there, but instead call probe_kernel_read() directly" * tag 'trace-v5.0-pre' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing/kprobes: Use probe_kernel_read instead of probe_mem_read tracing: Fix event filters and triggers to handle negative numbers

2019-03-06iio: adc: fix warning in Qualcomm PM8xxx HK/XOADC driverLinus Torvalds1-7/+3
The pm8xxx_get_channel() implementation is unclear, and causes gcc to suddenly generate odd warnings. The trigger for the warning (at least for me) was the entirely unrelated commit 79a4e91d1bb2 ("device.h: Add __cold to dev_<level> logging functions"), which apparently changes gcc code generation in the caller function enough to cause this: drivers/iio/adc/qcom-pm8xxx-xoadc.c: In function ‘pm8xxx_xoadc_probe’: drivers/iio/adc/qcom-pm8xxx-xoadc.c:633:8: warning: ‘ch’ may be used uninitialized in this function [-Wmaybe-uninitialized] ret = pm8xxx_read_channel_rsv(adc, ch, AMUX_RSV4, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ &read_nomux_rsv4, true); ~~~~~~~~~~~~~~~~~~~~~~~ drivers/iio/adc/qcom-pm8xxx-xoadc.c:426:27: note: ‘ch’ was declared here struct pm8xxx_chan_info *ch; ^~ because gcc for some reason then isn't able to see that the termination condition for the "for( )" loop in that function is also the condition for returning NULL. So it's not _actually_ uninitialized, but the function is admittedly just unnecessarily oddly written. Simplify and clarify the function, making gcc also see that it always returns a valid initialized value.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull locking updates from Ingo Molnar: "The biggest part of this tree is the new auto-generated atomics API wrappers by Mark Rutland. The primary motivation was to allow instrumentation without uglifying the primary source code. The linecount increase comes from adding the auto-generated files to the Git space as well: include/asm-generic/atomic-instrumented.h | 1689 ++++++++++++++++-- include/asm-generic/atomic-long.h | 1174 ++++++++++--- include/linux/atomic-fallback.h | 2295 +++++++++++++++++++++++++ include/linux/atomic.h | 1241 +------------ I preferred this approach, so that the full call stack of the (already complex) locking APIs is still fully visible in 'git grep'. But if this is excessive we could certainly hide them. There's a separate build-time mechanism to determine whether the headers are out of date (they should never be stale if we do our job right). Anyway, nothing from this should be visible to regular kernel developers. Other changes: - Add support for dynamic keys, which removes a source of false positives in the workqueue code, among other things (Bart Van Assche) - Updates to tools/memory-model (Andrea Parri, Paul E.
