      bnxt_en: Fix _bnxt_get_max_rings() for 57500 chips. · e30fbc33
      Michael Chan authored
      The CP rings are accounted differently on the new 57500 chips.  There
      must be enough CP rings for the sum of RX and TX rings on the new
      chips.  The current logic may be over-estimating the RX and TX rings.
      
      The output parameter max_cp should be the maximum NQs capped by
      MSIX vectors available for networking in the context of 57500 chips.
      The existing code which uses CMPL rings capped by the MSIX vectors
      works most of the time but is not always correct.

      bnxt_en: Fix NQ/CP rings accounting on the new 57500 chips. · c0b8cda0
      Michael Chan authored
      The new 57500 chips have introduced the NQ structure in addition to
      the existing CP rings in all chips.  We need to introduce a new
      bnxt_nq_rings_in_use().  On legacy chips, the 2 functions are the
      same and one will just call the other.  On the new chips, they
      refer to the 2 separate ring structures.  The new function is now
      called to determine the resource (NQ or CP rings) associated with
      MSIX that are in use.
      
      On 57500 chips, the RDMA driver does not use the CP rings so
      we don't need to do the subtraction adjustment.

      Michael Chan authored
      The new 57500 chips use 1 NQ per MSIX vector, whereas legacy chips use
      1 CP ring per MSIX vector.  To better unify this, add a resv_irqs
      field to struct bnxt_hw_resc.  On legacy chips, we initialize resv_irqs
      with resv_cp_rings.  On new chips, we initialize it with the allocated
      MSIX resources.

      Michael Chan authored
      Recent changes to support the 57500 devices have created this
      regression.  The bnxt_hwrm_queue_qportcfg() call was moved to be
      called earlier before the RDMA support was determined, causing
      the CoS queues configuration to be set before knowing whether RDMA
      was supported or not.  Fix it by moving it to the right place right
      after RDMA support is determined.

       "A regression fix for the Address Range Scrub implementation, yes
        another one, and support for platforms that misalign persistent memory
        relative to the Linux memory hotplug section constraint. Longer term,
        support for sub-section memory hotplug would alleviate alignment
        waste, but until then this hack allows a 'struct page' memmap to be
        established for these misaligned memory regions.
      
        These have all appeared in a -next release, and thanks to Patrick for
        reporting and testing the alignment padding fix.
      
        Summary:
      
         - Unless and until the core mm handles memory hotplug units smaller
           than a section (128M), persistent memory namespaces must be padded
           to section alignment.
      
           The libnvdimm core already handled section collision with "System
           RAM", but some configurations overlap independent "Persistent
           Memory" ranges within a section, so additional padding injection is
           added for that case.
      
         - The recent reworks of the ARS (address range scrub) state machine
           to reduce the number of state flags inadvertantly missed a
           conversion of acpi_nfit_ars_rescan() call sites. Fix the regression
           whereby user-requested ARS results in a "short" scrub rather than a
           "long" scrub.

           mocked test resources.

      Linus Torvalds authored
      Pull xfs fixes from Darrick Wong:
       "Here are hopefully the last set of fixes for 4.20.
      
        There's a fix for a longstanding statfs reporting problem with project
        quotas, a correction for page cache invalidation behaviors when
        fallocating near EOF, and a fix for a broken metadata verifier return
        code.
      
        Finally, the most important fix is to the pipe splicing code (aka the
        generic copy_file_range fallback) to avoid pointless short directio
        reads by only asking the filesystem for as much data as there are
        available pages in the pipe buffer. Our previous fix (simulated short
        directio reads because the number of pages didn't match the length of
        the read requested) caused subtle problems on overlayfs, so that part
        is reverted.
      
        Anyhow, this series passes fstests -g all on xfs and overlay+xfs, and
        has passed 17 billion fsx operations problem-free since I started
        testing
      
        Summary:
      
         - Fix broken project quota inode counts
      
         - Fix incorrect PAGE_MASK/PAGE_SIZE usage
      
         - Fix incorrect return value in btree verifier
      
         - Fix WARN_ON remap flags false positive
      
         - Fix splice read overflows"

        splice: don't read more than available pipe space
        vfs: allow some remap flags to be passed to vfs_clone_file_range
        xfs: fix inverted return from xfs_btree_sblock_verify_crc

      Revert "mm, thp: consolidate THP gfp handling into alloc_hugepage_direct_gfpmask" · 356ff8a9
      David Rientjes authored
      This reverts commit 89c83fb5.
      
      This should have been done as part of 2f0799a0 ("mm, thp: restore
      node-local hugepage allocations").  The movement of the thp allocation
      policy from alloc_pages_vma() to alloc_hugepage_direct_gfpmask() was
      intended to only set __GFP_THISNODE for mempolicies that are not
      MPOL_BIND whereas the revert could set this regardless of mempolicy.
      
      While the check for MPOL_BIND between alloc_hugepage_direct_gfpmask()
      and alloc_pages_vma() was racy, that has since been removed since the
      revert.  What is left is the possibility to use __GFP_THISNODE in
      policy_node() when it is unexpected because the special handling for
      hugepages in alloc_pages_vma()  was removed as part of the consolidation.
      
      Secondly, prior to 89c83fb5, alloc_pages_vma() implemented a somewhat
      different policy for hugepage allocations, which were allocated through
      alloc_hugepage_vma().  For hugepage allocations, if the allocating
      process's node is in the set of allowed nodes, allocate with
      __GFP_THISNODE for that node (for MPOL_PREFERRED, use that node with
      __GFP_THISNODE instead).  This was changed for shmem_alloc_hugepage() to
      allow fallback to other nodes in 89c83fb5 as it did for new_page() in
      mm/mempolicy.c which is functionally different behavior and removes the
      requirement to only allocate hugepages locally.
      
      So this commit does a full revert of 89c83fb5 instead of the partial
      revert that was done in 2f0799a0.  The result is the same thp
      allocation policy for 4.20 that was in 4.19.
      
      Fixes: 89c83fb5 ("mm, thp: consolidate THP gfp handling into alloc_hugepage_direct_gfpmask")
      Fixes: 2f0799a0 ("mm, thp: restore node-local hugepage allocations")

      Revert "net/ibm/emac: wrong bit is used for STA control" · 5b3279e2
      Benjamin Herrenschmidt authored
      This reverts commit 624ca9c3.
      
      This commit is completely bogus. The STACR register has two formats, old
      and new, depending on the version of the IP block used. There's a pair of
      device-tree properties that can be used to specify the format used:
      
      	has-inverted-stacr-oc
      	has-new-stacr-staopc
      
      What this commit did was to change the bit definition used with the old
      parts to match the new parts. This of course breaks the driver on all
      the old ones.
      
      Instead, the author should have set the appropriate properties in the
      device-tree for the variant used on his board.
