• patina\_dxe\_core: Fix memory allocation tests for aarch64 runtime types @cfernald (#1241)
  
  Change Details

    ## Description

  Current implementations of several tests and hob construction logic use a single page for runtime memory types. On aarch64, the runtime page allocation granularity is 64kb, so all of these memory regions are dropped causing the tests to fail.

• patina\_internal\_cpu: remove page table creation test @cfernald (#1242)
  
  Change Details

    ## Description

  This removes a test that causes exception on aarch64 targets. This test attempts to create an offline page table from user-mode which is not currently supported by the patina-paging crate as it will access system registers during table initialization. No equivalent test exists for x64.

🐛 Bug Fixes

• bugfix: Enable compat mode for EFI\_APPLICATION @Javagedes (#1249)
  
  Change Details

    ## Description

  In bde612d (written by me), I updated the logic around when to apply compatibility mode from being for a EFI_APPLICATION to a EFI_RUNTIME_DRIVER. Not sure how or why, but it was completely my fault. This fixes that.

  This was caught during my work to created nightly "boot to os" github workflow.

• patina\_internal\_collections: Prevent out-of-bounds access in resize() @makubacki (#1243)
  
  Change Details

    ## Description

  Add bounds checking before accessing buffer[idx] in Storage::resize().

  When resizing to a buffer with no free space (idx >= buffer.len()), set available to null instead of attempting to access out-of-bounds memory.
