Last change on this file since ddcc8a0 was ddcc8a0, checked in by Jakub Jermar <jakub@…>, 14 years ago

Split frame_arch_init() into two parts.

  • frame_low_arch_init() is meant to initialize physical memory that will be accessible using the kernel identity mapping
  • frame_high_arch_init() is meant to initialize physical memory beyond the reach of the kernel identity mapping; zones in the high memory should have configuration frames allocated externally from the low memory (which will be allowed)
  • Property mode set to 100644
