      ACPI / hotplug / PCI: Runtime resume bridges before bus rescans · dd7fd3a8
      Rafael J. Wysocki authored
      If a PCI bridge (or PCIe port) that is runtime-suspended gets an ACPI
      hotplug notification, such as a bus check, it has to be resumed before
      re-scanning the devices below it, or those devices will not be
      accessible and will be treated as hot-removed.
      
      Make that happen and let the bridge suspend again after the bus below it
      has been re-scanned.
      
      This is a replacement for commit 16468c78 ("ACPI / hotplug / PCI:
      Runtime resume bridge before rescan") that has been reverted, because it
      introduced a system resume regression (due to missing bridge->pci_dev
      checks that are necessary in case the notification is targeted at the
      host bridge) and it is necessary for the code added by commit
      006d44e4 ("PCI: Add runtime PM support for PCIe ports") to work as
      expected.

      mm/memblock.c: fix NULL dereference error · e47608ab
      zijun_hu authored
      It causes NULL dereference error and failure to get type_a->regions[0]
      info if parameter type_b of __next_mem_range_rev() == NULL
      
      Fix this by checking before dereferring and initializing idx_b to 0
      
      The approach is tested by dumping all types of region via
      __memblock_dump_all() and __next_mem_range_rev() fixed to UART
      separately the result is okay after checking the logs.

      At present it is obvious that memory online and offline will fail when

      vfs_{create,mkdir,mknod} each begin with a call to may_create(), which

      This check is therefore unnecessary.
      
      (In the NFSv2 case, nfsd_proc_create also has such a check.  Contrary to
      RFC 1094, our code seems to believe that a CREATE of an existing file
      should succeed.  I'm leaving that behavior alone.)

      There's some odd logic in nfsd_create() that allows it to be called with
      the parent directory either locked or unlocked.  The only already-locked
      caller is NFSv2's nfsd_proc_create().  It's less confusing to split out
      the unlocked case into a separate function which the NFSv2 code can call
      directly.
      
      Also fix some comments while we're here.

      lookup_one_len already has this check.
      
      The only effect of this patch is to return access instead of perm in the
      0-length-filename case.  I actually prefer nfserr_perm (or _inval?), but
      I doubt anyone cares.
      
      The isdotent check seems redundant too, but I worry that some client

      nfsd: Make creates return EEXIST instead of EACCES · 7eed34f1
      Oleg Drokin authored
      When doing a create (mkdir/mknod) on a name, it's worth
      checking the name exists first before returning EACCES in case
      the directory is not writeable by the user.
      This makes return values on the client more consistent
      regardless of whenever the entry there is cached in the local
      cache or not.
      Another positive side effect is certain programs only expect
      EEXIST in that case even despite POSIX allowing any valid
      error to be returned.

      metag: Fix __cmpxchg_u32 asm constraint for CMP · 6154c187
      James Hogan authored
      The LNKGET based atomic sequence in __cmpxchg_u32 has slightly incorrect
      constraints for the return value which under certain circumstances can
      allow an address unit register to be used as the first operand of a CMP
      instruction. This isn't a valid instruction however as the encodings
      only allow a data unit to be specified. This would result in an
      assembler error like the following:
      
        Error: failed to assemble instruction: "CMP A0.2,D0Ar6"
      
      Fix by changing the constraint from "=&da" (assigned, early clobbered,
      data or address unit register) to "=&d" (data unit register only).
      
      The constraint for the second operand, "bd" (an op2 register where op1
      is a data unit register and the instruction supports O2R) is already
      correct assuming the first operand is a data unit register.
      
      Other cases of CMP in inline asm have had their constraints checked, and
      appear to all be fine.

      Soft RoCE driver · 8700e3e7
      Moni Shoua authored
      Soft RoCE (RXE) - The software RoCE driver
      
      ib_rxe implements the RDMA transport and registers to the RDMA core
      device as a kernel verbs provider. It also implements the packet IO
      layer. On the other hand ib_rxe registers to the Linux netdev stack
      as a udp encapsulating protocol, in that case RDMA, for sending and
      receiving packets over any Ethernet device.  This yields a RDMA
      transport over the UDP/Ethernet network layer forming a RoCEv2
      compatible device.
      
      The configuration procedure of the Soft RoCE drivers requires
      binding to any existing Ethernet network device. This is done with
      /sys interface.
      
      A userspace Soft RoCE library (librxe) provides user applications
      the ability to run with Soft RoCE devices.  The use of rxe verbs ins
      user space requires the inclusion of librxe as a device specifics
      plug-in to libibverbs. librxe is packaged separately.

      dynamic_debug: add jump label support · 9049fc74
      Jason Baron authored
      Although dynamic debug is often only used for debug builds, sometimes
      its enabled for production builds as well.  Minimize its impact by using
      jump labels.  This reduces the text section by 7000+ bytes in the kernel
      image below.  It does increase data, but this should only be referenced
      when changing the direction of the branches, and hence usually not in
      cache.

      jump_label: remove bug.h, atomic.h dependencies for HAVE_JUMP_LABEL · 1f69bf9c
      Jason Baron authored
      The current jump_label.h includes bug.h for things such as WARN_ON().
      This makes the header problematic for inclusion by kernel.h or any
      headers that kernel.h includes, since bug.h includes kernel.h (circular
      dependency).  The inclusion of atomic.h is similarly problematic.  Thus,
      this should make jump_label.h 'includable' from most places.

      arm: jump label may reference text in __exit · ddb45306
      Jason Baron authored
      The jump table can reference text found in an __exit section.  Thus,
      instead of discarding it at build time, include EXIT_TEXT as part of
      __init and it will be released when the system boots.

      tile: support static_key usage in non-module __exit sections · c14b4bcf
      Chris Metcalf authored
      Previously, all the __exit sections were just dropped by the link phase.
      However, if there are static_key (jump label) constructs in __exit
      sections that are not modules, the link fails with the message:
      
         `.exit.text' referenced in section `__jump_table' of xxx.o:
         defined in discarded section `.exit.text' of xxx.o
      
      Support this usage by keeping the .exit.text sections in the final image
      if JUMP_LABEL is defined, then discarding them once initialization is
      complete.
