Commit 594cc251 ("make 'user_access_begin()' do 'access_ok()'")
makes the access_ok() check part of the user_access_begin() preceding a
series of 'unsafe' accesses.  This has the desirable effect of ensuring
that all 'unsafe' accesses have been range-checked, without having to
pick through all of the callsites to verify whether the appropriate
checking has been made.

However, the consolidated range check does not inhibit speculation, so
it is still up to the caller to ensure that they are not susceptible to
any speculative side-channel attacks for user addresses that ultimately
fail the access_ok() check.

This is an oversight, so use __uaccess_begin_nospec() to ensure that
speculation is inhibited until the access_ok() check has passed.

 "These fix an ACPI initialization ordering issue introduced in the 4.17

  Specifics:

   - Restore the ACPI initialization ordering changed implicitly by the
     module-level AML handling rework during the 4.17 development cycle
     that caused the EC address space handler based on information from
     ECDT to be set up before loading AML definition blocks, making it
     effectively not accessible by AML on some systems that don't work
     as expected any more (Rafael Wysocki).

   - Add direct dependencies on PCI to Kconfig in multiple places for
     code that depends on both ACPI and PCI, but the PCI dependency was
     implicitly satisfied by the ACPI dependency before, to prevent
     invalid configurations from being created, for example by

When lp55xx_read() fails, "status" is an uninitialized variable and thus
may contain random value; using it leads to undefined behaviors.

The fix inserts a check for the return value of lp55xx_read: if it
fails, returns with its error code.

Pull AFS fixes from David Howells:
 "Here's a set of fixes for AFS:

   - Use struct_size() for kzalloc() size calculation.

   - When calling YFS.CreateFile rather than AFS.CreateFile, it is
     possible to create a file with a file lock already held. The
     default value indicating no lock required is actually -1, not 0.

   - Fix an oops in inode/vnode validation if the target inode doesn't
     have a server interest assigned (ie. a server that will notify us
     of changes by third parties).

   - Fix refcounting of keys in file locking.

   - Fix a race in refcounting asynchronous operations in the event of
     an error during request transmission. The provision of a dedicated
     function to get an extra ref on a call is split into a separate
     commit"

Pull swiotlb fix from Konrad Rzeszutek Wilk:
 "A tiny fix for v5.0-rc2:

  This fixes an issue with GPU cards not working anymore with the DMA
  mapping work Christopher did - as the SWIOTLB is initialized first and
  then free'd (as IOMMU is available) but we forgot to clear our start
  and end entries which are used and BOOM"
