2018-10-26Revert "x86/e820: put !E820_TYPE_RAM regions into memblock.reserved"Masayoshi Mizuma1-12/+3
commit 124049decbb1 ("x86/e820: put !E820_TYPE_RAM regions into memblock.reserved") breaks movable_node kernel option because it changed the memory gap range to reserved memblock. So, the node is marked as Normal zone even if the SRAT has Hot pluggable affinity. ===================================================================== kernel: BIOS-e820: [mem 0x0000180000000000-0x0000180fffffffff] usable kernel: BIOS-e820: [mem 0x00001c0000000000-0x00001c0fffffffff] usable ... kernel: reserved[0x12]#011[0x0000181000000000-0x00001bffffffffff], 0x000003f000000000 bytes flags: 0x0 ... kernel: ACPI: SRAT: Node 2 PXM 6 [mem 0x180000000000-0x1bffffffffff] hotplug kernel: ACPI: SRAT: Node 3 PXM 7 [mem 0x1c0000000000-0x1fffffffffff] hotplug ... kernel: Movable zone start for each node kernel: Node 3: 0x00001c0000000000 kernel: Early memory node ranges ... ===================================================================== The original issue is fixed by the former patches, so let's revert commit 124049decbb1 ("x86/e820: put !E820_TYPE_RAM regions into memblock.reserved").

memmap_init is sometimes a macro sometimes a function based on __HAVE_ARCH_MEMMAP_INIT. It is only a function on ia64. Make memmap_init a weak function instead, and let ia64 redefine it.

2018-10-26hugetlb: harmonize hugetlb.h arch specific defines with pgtable.hAlexandre Ghiti1-1/+1
In order to reduce copy/paste of functions across architectures and then make riscv hugetlb port (and future ports) simpler and smaller, this patchset intends to factorize the numerous hugetlb primitives that are defined across all the architectures. Except for prepare_hugepage_range, this patchset moves the versions that are just pass-through to standard pte primitives into asm-generic/hugetlb.h by using the same #ifdef semantic that can be found in asm-generic/pgtable.h, i.e. __HAVE_ARCH_***. s390 architecture has not been tackled in this serie since it does not use asm-generic/hugetlb.h at all. This patchset has been compiled on all addressed architectures with success (except for parisc, but the problem does not come from this series). This patch (of 11): asm-generic/hugetlb.h proposes generic implementations of hugetlb related functions: use __HAVE_ARCH_HUGE* defines in order to make arch specific implementations of hugetlb functions consistent with pgtable.h scheme.

2018-10-26alpha: switch to NO_BOOTMEMMike Rapoport4-188/+29
Replace bootmem allocator with memblock and enable use of NO_BOOTMEM like on most other architectures. Alpha gets the description of the physical memory from the firmware as an array of memory clusters. Each cluster that is not reserved by the firmware is added to memblock.memory. Once the memblock.memory is set up, we reserve the kernel and initrd pages with memblock reserve. Since we don't need the bootmem bitmap anymore, the code that finds an appropriate place is removed. The conversion does not take care of NUMA support which is marked broken for more than 10 years now.

2018-10-26unicore32: switch to NO_BOOTMEMMike Rapoport2-53/+2
The unicore32 architecture already supports memblock and uses it for some early memory reservations, e.g initrd and the page tables. At some point unicore32 allocates the bootmem bitmap from the memblock and then hands over the memory reservations from memblock to bootmem. This patch removes the bootmem initialization and leaves memblock as the only boot time memory manager for unicore32.

ARM64 has asm implementation of memchr(), memcmp(), str[r]chr(), str[n]cmp(), str[n]len(). KASAN don't see memory accesses in asm code, thus it can potentially miss many bugs. Ifdef out __HAVE_ARCH_* defines of these functions when KASAN is enabled, so the generic implementations from lib/string.c will be used. We can't just remove the asm functions because efistub uses them. And we can't have two non-weak functions either, so declare the asm functions as weak.

Leading to a 27% speedup for our context switch benchmark on Power9. - Improvements to our handling of SLB multi-hit errors. We now print more debug information when they occur, and try to continue running by flushing the SLB and reloading, rather than treating them as fatal. - Enable THP migration on 64-bit Book3S machines (eg. Power7/8/9). - Add support for physical memory up to 2PB in the linear mapping on 64-bit Book3S. We only support up to 512TB as regular system memory, otherwise the percpu allocator runs out of vmalloc space. - Add stack protector support for 32 and 64-bit, with a per-task canary. - Add support for PTRACE_SYSEMU and PTRACE_SYSEMU_SINGLESTEP. - Support recognising "big cores" on Power9, where two SMT4 cores are presented to us as a single SMT8 core. - A large series to cleanup some of our ioremap handling and PTE flags. - Add a driver for the PAPR SCM (storage class memory) interface, allowing guests to operate on SCM devices (acked by Dan). - Changes to our ftrace code to handle very large kernels, where we need to use a trampoline to get to ftrace_caller().

Pull RISC-V updates from Palmer Dabbelt: "This patch set contains a lot (at least, for me) of improvements to the RISC-V kernel port: - The removal of some cacheinfo values that were bogus. - On systems with F but without D the kernel will not show the F extension to userspace, as it isn't actually supported. - Support for futexes. - Removal of some unused code. - Cleanup of some menuconfig entries. - Support for systems without a floating-point unit, and for building kernels that will never use the floating-point unit. - More fixes to the RV32I port, which regressed again. It's really time to get this into a regression test somewhere so I stop breaking it. Thanks to Zong for resurrecting it again! - Various fixes that resulted from a year old review of our original patch set that I finally got around to. - Various improvements to SMP support, largely based around having switched to logical hart numbering, as well as some interrupt improvements. This one is in the same patch set as above, thanks to Atish for sheparding everything though as my patch set was a bit of a mess. I'm pretty sure this is our largest patch set since the original kernel contribution, and it's certainly the one with the most contributors.

Older versions of bintutils do not allow symbol math across different segments on sparc: ==================== Assembler messages: 99: Error: operation combines symbols in different segments ==================== This is controlled by whether or not DIFF_EXPR_OK is defined in gas/config/tc-*.h and for sparc this was not the case until mid-2017. So we have to patch between %stick and %tick another way. Do what powerpc does and emit two versions of the relevant functions, one using %tick and one using %stick, and patch the symbols in the dynamic symbol table.

Pull tty ioctl updates from Al Viro: "This is the compat_ioctl work related to tty ioctls. Quite a bit of dead code taken out, all tty-related stuff gone from fs/compat_ioctl.c. A bunch of compat bugs fixed - some still remain, but all more or less generic tty-related ioctls should be covered (remaining issues are in things like driver-private ioctls in a pcmcia serial card driver not getting properly handled in 32bit processes on 64bit host, etc)" * 'work.tty-ioctl' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (53 commits) kill TIOCSERGSTRUCT change semantics of ldisc ->compat_ioctl() kill TIOCSER[SG]WILD synclink_gt(): fix compat_ioctl() pty: fix compat ioctls compat_ioctl - kill keyboard ioctl handling gigaset: add ->compat_ioctl() vt_compat_ioctl(): clean up, use compat_ptr() properly gigaset: don't try to printk userland buffer contents dgnc: don't bother with (empty) stub for TCXONC dgnc: leave TIOC[GS]SOFTCAR to ldisc remove fallback to drivers for TIOCGICOUNT dgnc: break-related ioctls won't reach ->ioctl() kill the rest of tty COMPAT_IOCTL() entries dgnc: TIOCM... won't reach ->ioctl() isdn_tty: TCSBRK{,P} won't reach ->ioctl() kill capinc_tty_ioctl() take compat TIOC[SG]SERIAL treatment into tty_compat_ioctl() synclink: reduce pointless checks in ->ioctl() complete ->[sg]et_serial() switchover ...
