[PATCH v2 00/10] UEFI NX support and NX Linux loader using shim loader protocol

[Mate Kukri]

Currently the patchset consists of:
- Reworked Fedora NX patches to make GRUB itself work under NX.
- Julian Andres Klode's loader framework patch (used in Debian and Ubuntu for 
the downstream loader).
- Implemented shim loader protocol support using the above loader framework.
- Added patch to disallow using the legacy Linux loader when NX is required.

Future work:
- Implement NX in non-Linux loaders where applicable.
  (Note that this is non-crtitical for security, as non-UEFI/Linux loaders are 
disabled
   by SB lockdown, but would be nice to avoid crashes for unsuspecting users on 
future
   hardware).

Julian Andres Klode (1):
  efi: Provide wrappers for load_image, start_image, unload_image

Mate Kukri (6):
  modules: load module sections at page-aligned addresses
  nx: add memory attribute get/set API
  nx: set page permissions for loaded modules.
  nx: set the nx compatible flag in EFI grub images
  efi: Use shim's loader protocol for EFI image verification and loading
  efi: Disallow fallback to legacy Linux loader when shim says NX is
    required.

Peter Jones (3):
  modules: make .module_license read-only
  modules: strip .llvm_addrsig sections and similar.
  modules: Don't allocate space for non-allocable sections.
