Linus,

Three SELinux fixes for v6.11-rcX:

- Fix a xperms counting problem where we adding to the xperms count
  even if we failed to add the xperm.

- Propogate errors from avc_add_xperms_decision() back to the caller
  so that we can trigger the proper cleanup and error handling.

- Revert our use of vma_is_initial_heap() in favor of our older logic
  as vma_is_initial_heap() doesn't correctly handle the no-heap case
  and it is causing issues with the SELinux process/execheap access
  control.  While the older SELinux logic may not be perfect, it
  restores the expected user visible behavior.  Hopefully we will be
  able to resolve the problem with the vma_is_initial_heap() macro
  with the mm folks, but we need to fix this in the meantime.

-Paul
