      Pull netfs updates from David Howells:
       "Netfs prep for write helpers.
      
        Having had a go at implementing write helpers and content encryption
        support in netfslib, it seems that the netfs_read_{,sub}request
        structs and the equivalent write request structs were almost the same
        and so should be merged, thereby requiring only one set of
        alloc/get/put functions and a common set of tracepoints.
      
        Merging the structs also has the advantage that if a bounce buffer is
        added to the request struct, a read operation can be performed to fill
        the bounce buffer, the contents of the buffer can be modified and then
        a write operation can be performed on it to send the data wherever it
        needs to go using the same request structure all the way through. The
        I/O handlers would then transparently perform any required crypto.
        This should make it easier to perform RMW cycles if needed.
      
        The potentially common functions and structs, however, by their names
        all proclaim themselves to be associated with the read side of things.
      
        The bulk of these changes alter this in the following ways:
      
         - Rename struct netfs_read_{,sub}request to netfs_io_{,sub}request.
      
         - Rename some enums, members and flags to make them more appropriate.
      
         - Adjust some comments to match.
      
         - Drop "read"/"rreq" from the names of common functions. For
           instance, netfs_get_read_request() becomes netfs_get_request().
      
         - The ->init_rreq() and ->issue_op() methods become ->init_request()
           and ->issue_read(). I've kept the latter as a read-specific
           function and in another branch added an ->issue_write() method.
      
        The driver source is then reorganised into a number of files:
      
              fs/netfs/buffered_read.c        Create read reqs to the pagecache
              fs/netfs/io.c                   Dispatchers for read and write reqs
              fs/netfs/main.c                 Some general miscellaneous bits
              fs/netfs/objects.c              Alloc, get and put functions
              fs/netfs/stats.c                Optional procfs statistics.
      
        and future development can be fitted into this scheme, e.g.:
      
              fs/netfs/buffered_write.c       Modify the pagecache
              fs/netfs/buffered_flush.c       Writeback from the pagecache
              fs/netfs/direct_read.c          DIO read support
              fs/netfs/direct_write.c         DIO write support
              fs/netfs/unbuffered_write.c     Write modifications directly back
      
        Beyond the above changes, there are also some changes that affect how
        things work:
      
         - Make fscache_end_operation() generally available.
      
         - In the netfs tracing header, generate enums from the symbol ->
           string mapping tables rather than manually coding them.
      
         - Add a struct for filesystems that uses netfslib to put into their
           inode wrapper structs to hold extra state that netfslib is
           interested in, such as the fscache cookie. This allows netfslib
           functions to be set in filesystem operation tables and jumped to
           directly without having to have a filesystem wrapper.
      
         - Add a member to the struct added above to track the remote inode
           length as that may differ if local modifications are buffered. We
           may need to supply an appropriate EOF pointer when storing data (in
           AFS for example).
      
         - Pass extra information to netfs_alloc_request() so that the
           ->init_request() hook can access it and retain information to
           indicate the origin of the operation.
      
         - Make the ->init_request() hook return an error, thereby allowing a
           filesystem that isn't allowed to cache an inode (ceph or cifs, for
           example) to skip readahead.
      
         - Switch to using refcount_t for subrequests and add tracepoints to
           log refcount changes for the request and subrequest structs.
      
         - Add a function to consolidate dispatching a read request. Similar
           code is used in three places and another couple are likely to be
           added in the future"

      Pull random number generator fixes from Jason Donenfeld:
      
       - If a hardware random number generator passes a sufficiently large
         chunk of entropy to random.c during early boot, we now skip the
         "fast_init" business and let it initialize the RNG.
      
         This makes CONFIG_RANDOM_TRUST_BOOTLOADER=y actually useful.
      
       - We already have the command line `random.trust_cpu=0/1` option for
         RDRAND, which let distros enable CONFIG_RANDOM_TRUST_CPU=y while
         placating concerns of more paranoid users.
      
         Now we add `random.trust_bootloader=0/1` so that distros can
         similarly enable CONFIG_RANDOM_TRUST_BOOTLOADER=y.
      
       - Re-add a comment that got removed by accident in the recent revert.
      
       - Add the spec-compliant ACPI CID for vmgenid, which Microsoft added to
         the vmgenid spec at Ard's request during earlier review.
      
       - Restore build-time randomness via the latent entropy plugin, which
         was lost when we transitioned to using a hash function.

      random: mix build-time latent entropy into pool at init · 1754abb3
      Jason A. Donenfeld authored
      Prior, the "input_pool_data" array needed no real initialization, and so
      it was easy to mark it with __latent_entropy to populate it during
      compile-time. In switching to using a hash function, this required us to
      specifically initialize it to some specific state, which means we
      dropped the __latent_entropy attribute. An unfortunate side effect was
      this meant the pool was no longer seeded using compile-time random data.
      In order to bring this back, we declare an array in rand_initialize()
      with __latent_entropy and call mix_pool_bytes() on that at init, which
      accomplishes the same thing as before. We make this __initconst, so that
      it doesn't take up space at runtime after init.

      gfs2: Make sure FITRIM minlen is rounded up to fs block size · 27ca8273
      Andrew Price authored
      Per fstrim(8) we must round up the minlen argument to the fs block size.
      The current calculation doesn't take into account devices that have a
      discard granularity and requested minlen less than 1 fs block, so the
      value can get shifted away to zero in the translation to fs blocks.
      
      The zero minlen passed to gfs2_rgrp_send_discards() then allows
      sb_issue_discard() to be called with nr_sects == 0 which returns -EINVAL
      and results in gfs2_rgrp_send_discards() returning -EIO.
      
      Make sure minlen is never < 1 fs block by taking the max of the
      requested minlen and the fs block size before comparing to the device's
      discard granularity and shifting to fs blocks.

      ARM/dma-mapping: Remove CMA code when not built with CMA · 229a08a4
      Kees Cook authored
      The MAX_CMA_AREAS could be set to 0, which would result in code that would
      attempt to operate beyond the end of a zero-sized array. If CONFIG_CMA
      is disabled, just remove this code entirely. Found when building arm
      on GCC 10.x for several defconfigs (e.g. axm55xx_defconfig) under
      -Warray-bounds:
      
      arch/arm/mm/dma-mapping.c:396:22: warning: array subscript <unknown> is outside array bounds of 'struct dma_contig_early_reserve[0]' [-Warray-bounds]
