We cannot detect clang before including the arch Makefile, because that can set the default cross compiler. We also cannot detect clang after including the arch Makefile, because powerpc wants to know about clang. Solve this by using an deferred variable. This costs us a few shell invocations, but this is only a constant number.

Jan Kara and Thomas Gleixner reported boot crashes in the FPU code: general protection fault: 0000 [#1] SMP RIP: 0010:[<ffffffff81048a6c>] [<ffffffff81048a6c>] mxcsr_feature_mask_init+0x1c/0x40 2b:* 0f ae 85 00 fe ff ff fxsave -0x200(%rbp) and bisected it down to the following FPU commit: 91a8c2a5 ("x86/fpu: Clean up and fix MXCSR handling") The reason is that the on-stack FPU registers state variable, used by the FXSAVE instruction, did not have the required minimum alignment of 16 bytes, causing the general protection fault. This is most likely a GCC bug in older GCC versions, but the offending commit also added a bogus extra 32-byte alignment (which GCC ignored too). So fix this bug by making the variable static again, but also mark it __initdata this time, because fpu__init_system_mxcsr() is now an __init function.

It is normal that firmware presents GICC entry or entries (processors) with disabled flag in ACPI MADT, taking a system of 16 cpus for example, ACPI firmware may present 8 ebabled first with another 8 cpus disabled in MADT, the disabled cpus can be hot-added later. Firmware may also present more cpus than the hardware actually has, but disabled the unused ones, and easily enable it when the hardware has such cpus to make the firmware code scalable. So that's not an error for disabled cpus in MADT, we can switch pr_err() to pr_debug() to make the boot a little quieter by default. Since hwid for disabled cpus often are invalid, and we check invalid hwid first in the code, for use case that hot add cpus later will be filtered out and will not be counted in possible cups, so move this check before the hwid one to prepare the code to count for disabeld cpus when cpu hot-plug is introduced.

Any parameter passed after '--' in the kernel command-line will not be parsed by the kernel at all, instead it will be passed directly to init process. Currently the kernel appends elfcorehdr=<paddr> to the cmdline passed from kexec load, and if this command-line is used to pass parameters to init process this means that 'elfcorehdr' will not be parsed as a kernel parameter at all which will be a problem for vmcore subsystem since it will know nothing about the location of the ELF structure! Prepending 'elfcorehdr' instead of appending it fixes this problem since it ensures that it always comes before '--' and so it's always parsed as a kernel command-line parameter. Even with this patch things can still go wrong if 'CONFIG_CMDLINE' was also used to embedd a command-line to the crash dump kernel and this command-line contains '--' since the current behavior of the kernel is to actually append the boot loader command-line to the embedded command-line.

__early_pfn_to_nid() use static variables to cache recent lookups as memblock lookups are very expensive but it assumes that memory initialisation is single-threaded. Parallel initialisation of struct pages will break that assumption so this patch makes __early_pfn_to_nid() SMP-safe by requiring the caller to cache recent search information. early_pfn_to_nid() keeps the same interface but is only safe to use early in boot due to the use of a global static variable. meminit_pfn_in_nid() is an SMP-safe version that callers must maintain their own state for.

Commit 1b7b938f ("perf/x86/intel: Fix PMI handling for Intel PT") conditionally increments active_events in x86_add_exclusive() but unconditionally decrements in x86_del_exclusive(). These extra decrements can lead to the situation where active_events is zero and thus the PMI handler is 'disabled' while we have active events on the PMU generating PMIs. This leads to a truckload of: Uhhuh. NMI received for unknown reason 21 on CPU 28. Do you have a strange power saving mode enabled? Dazed and confused, but trying to continue messages and generally messes up perf. Remove the condition on the increment, double increment balanced by a double decrement is perfectly fine.

Mike Galbraith reported: " My i7-4790 box is having one hell of a time with this merge window, dead in the water. BIOS setting "Limit CPUID Maximum" upsets new fpu code mightily. " It turns out that Linux does a double workaround here, as per: 066941bd ("x86: unmask CPUID levels on Intel CPUs") it undoes the BIOS workaround - but as a side effect the CPUID state is not completely constant during early init anymore, and the new FPU init code did not take this into account. So what happened is that the xstate init code did not have full CPUID available, which broke subsequent attempts to use xstate features. Fix this by ordering the early FPU init code to after we've stabilized the CPUID state.

Based on an original patch by Ross Zwisler [1]. Writes to persistent memory have the potential to be posted to cpu cache, cpu write buffers, and platform write buffers (memory controller) before being committed to persistent media. Provide apis, memcpy_to_pmem(), wmb_pmem(), and memremap_pmem(), to write data to pmem and assert that it is durable in PMEM (a persistent linear address range). A '__pmem' attribute is added so sparse can track proper usage of pointers to pmem. This continues the status quo of pmem being x86 only for 4.2, but reworks to ioremap, and wider implementation of memremap() will enable other archs in 4.3.

ACPI NFIT table has System Physical Address Range Structure entries that describe a proximity ID of each range when ACPI_NFIT_PROXIMITY_VALID is set in the flags. Change acpi_nfit_register_region() to map a proximity ID to its node ID, and set it to a new numa_node field of nd_region_desc, which is then conveyed to the nd_region device. The device core arranges for btt and namespace devices to inherit their node from their parent region.

Upper bits should be zeroed in endianness conversion: - even when there's no need to change endianness (i.e., BPF_FROM_BE on big endian or BPF_FROM_LE on little endian); - after rev16. This patch fixes such bugs by emitting extra instructions to clear upper bits.
