      ACPI / ARM64 : use the new BAD_MADT_GICC_ENTRY macro · 99e3e3ae
      Al Stone authored
      For those parts of the arm64 ACPI code that need to check GICC subtables
      in the MADT, use the new BAD_MADT_GICC_ENTRY macro instead of the previous
      BAD_MADT_ENTRY.  The new macro takes into account differences in the size
      of the GICC subtable that the old macro did not; this caused failures even
      though the subtable entries are valid.
      
      Fixes: aeb823bb ("ACPICA: ACPI 6.0: Add changes for FADT table.")

      ACPI / ARM64: add BAD_MADT_GICC_ENTRY() macro · b6cfb277
      Al Stone authored
      The BAD_MADT_ENTRY() macro is designed to work for all of the subtables
      of the MADT.  In the ACPI 5.1 version of the spec, the struct for the
      GICC subtable (struct acpi_madt_generic_interrupt) is 76 bytes long; in
      ACPI 6.0, the struct is 80 bytes long.  But, there is only one definition
      in ACPICA for this struct -- and that is the 6.0 version.  Hence, when
      BAD_MADT_ENTRY() compares the struct size to the length in the GICC
      subtable, it fails if 5.1 structs are in use, and there are systems in
      the wild that have them.
      
      This patch adds the BAD_MADT_GICC_ENTRY() that checks the GICC subtable
      only, accounting for the difference in specification versions that are
      possible.  The BAD_MADT_ENTRY() will continue to work as is for all other
      MADT subtables.
      
      This code is being added to an arm64 header file since that is currently
      the only architecture using the GICC subtable of the MADT.  As a GIC is
      specific to ARM, it is also unlikely the subtable will be used elsewhere.

      bluetooth: fix list handling · 9b284cbd
      Linus Torvalds authored
      Commit 835a6a2f ("Bluetooth: Stop sabotaging list poisoning")
      thought that the code was sabotaging the list poisoning when NULL'ing
      out the list pointers and removed it.
      
      But what was going on was that the bluetooth code was using NULL
      pointers for the list as a way to mark it empty, and that commit just
      broke it (and replaced the test with NULL with a "list_empty()" test on
      a uninitialized list instead, breaking things even further).
      
      So fix it all up to use the regular and real list_empty() handling
      (which does not use NULL, but a pointer to itself), also making sure to
      initialize the list properly (the previous NULL case was initialized
      implicitly by the session being allocated with kzalloc())
      
      This is a combination of patches by Marcel Holtmann and Tedd Ho-Jeong
      An.
      
      [ I would normally expect to get this through the bt tree, but I'm going
        to release -rc1, so I'm just committing this directly   - Linus ]
