Subject: [PATCH v3 0/4] Merge contiguous physical memory regions

From: Longpeng <>

Hi guys,

This patchset try to merge the contiguous physical memory regions when
set user memory regions, you can see message in PATCH 1 for details.
Please review when you free, thank!

Changes v2 -> v3:
  Patch 1:
    - update the commit title and commit message.  [Andra]
    - use 'struct range' to instead of 'struct phys_mem_region'.  [Andra, Greg KH]
    - add comments before the function definition.  [Andra]
    - rename several variables, parameters and function.  [Andra]
  Patch 2:
    - update the commit title and commit message.  [Andra]
    - add comments before the function definition.  [Andra]
    - remove 'inline' attribute of ne_sanity_check_phys_mem_region. [Andra]
    - leave a blank line before return.  [Andra]
    - move sanity check in ne_merge_phys_contig_memory_regions to
      the beginning of the function.  [Andra]
    - double sanity checking after the merge of physical contiguous
      memory regions has been completed.  [Andra]
  Patch 3:
    - update the commit title and commit message.  [Andra]
    - use "misc_dev"/"misc device"/"MISC_DEV" to be more specific.  [Andra]
  Patch 4:
    - update the commit title and commit message.  [Andra]
    - align the fileds in 'struct phys_regions_test'.  [Andra]
    - rename 'phys_regions_testcases' to 'phys_regions_test_cases'.  [Andra]
    - add comments before each test cases.  [Andra]
    - initialize the variables in ne_misc_dev_test_merge_phys_contig_memory_regions.  [Andra]

Changes v1 -> v2:
  - update the commit message as Andra's suggestion  [Andra]
  - remove TODO completely in ne_set_user_memory_region_ioctl  [Andra]
  - extract the physical memory regions setup into individual
  - add kunit tests  [Andra]

Longpeng (4):
  nitro_enclaves: Merge contiguous physical memory regions
  nitro_enclaves: Sanity check physical memory regions during merging
  nitro_enclaves: Add KUnit tests setup for the misc device
  nitro_enclaves: Add KUnit tests for contiguous physical memory regions
