   8 commit 0ba80d96585662299d4ea4624043759ce9015421 upstream.
   9
  10 The current implementation for loading coalesced KPU profiles has
  11 a limitation.  The "offset" field, which is used to locate profiles
  12 within the profile is restricted to a u16.
  13
  14 This restricts the number of profiles that can be loaded. This patch
  15 addresses this limitation by increasing the size of the "offset" field.
