      Pull more ACPI updates from Rafael Wysocki:
       "Two more fixes in ACPI drivers, one in the ACPI EC driver
        (stable-candidate) and one in the ACPI button driver.
      
        Specifics:
      
         - An ACPI EC driver fix from the 4.3 cycle may cause the ACPICA's
           method reentrancy limit to be exceeded for a _Qxx method due to a
           large number of concurrent EC operations, so prevent that from
           happening by moving the EC handling into a separate workqueue with
           a limit on the number of concurrently executed work items (Lv
           Zheng)
      
         - Fix the cleanup code in the ACPI button driver that forgets to
           clear two variables on exit which causes an error to occur on the
           next attmpt to load the driver (Benjamin Tissoires)"

      Pull more power management updates from Rafael Wysocki:
       "A few more fixes and cleanups in the x86-64 low-level hibernation
        code, PM core, cpufreq (Kconfig and intel_pstate), and the operating
        points framework.
      
        Specifics:
      
         - Prevent the low-level assembly hibernate code on x86-64 from
           referring to __PAGE_OFFSET directly as a symbol which doesn't work
           when the kernel identity mapping base is randomized, in which case
           __PAGE_OFFSET is a variable (Rafael Wysocki).
      
         - Avoid selecting CPU_FREQ_STAT by default as the statistics are not
           required for proper cpufreq operation (Borislav Petkov).
      
         - Add Skylake-X and Broadwell-X IDs to the intel_pstate's list of
           processors where out-of-band (OBB) control of P-states is possible
           and if that is in use, intel_pstate should not attempt to manage
           P-states (Srinivas Pandruvada).
      
         - Drop some unnecessary checks from the wakeup IRQ handling code in
           the PM core (Markus Elfring).
      
         - Reduce the number operating performance point (OPP) lookups in one
           of the OPP framework's helper functions (Jisheng Zhang)"

      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.

       "Highlights:
      
         - Trond made a change to the server's tcp logic that allows a fast
           client to better take advantage of high bandwidth networks, but may
           increase the risk that a single client could starve other clients;
           a new sunrpc.svc_rpc_per_connection_limit parameter should help
           mitigate this in the (hopefully unlikely) event this becomes a
           problem in practice.
      
         - Tom Haynes added a minimal flex-layout pnfs server, which is of no
           use in production for now--don't build it unless you're doing

      nfsd: remove unnecessary positive-dentry check · d03d9fe4
      J. Bruce Fields authored
      vfs_{create,mkdir,mknod} each begin with a call to may_create(), which
      returns EEXIST if the object already exists.
      
      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.)

      nfsd: reorganize nfsd_create · b44061d0
      J. Bruce Fields authored
      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.

      nfsd: check d_can_lookup in fh_verify of directories · e75b23f9
      J. Bruce Fields authored
      Create and other nfsd ops generally assume we can call lookup_one_len on
      inodes with S_IFDIR set.  Al says that this assumption isn't true in
      general, though it should be for the filesystem objects nfsd sees.
      
      Add a check just to make sure our assumption isn't violated.
      
      Remove a couple checks for i_op->lookup in create code.

      nfsd: remove redundant zero-length check from create · 12391d07
      J. Bruce Fields authored
      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
      might actually care about that strange nfserr_exist error.

      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.
