Last change on this file since d0a0f12 was 4b2c872d, checked in by Jakub Jermar <jakub@…>, 20 years ago

Create generic context_save() and context_restore().
These two functions are defined inline and only call context_save_arch() and context_restore_arch(), respectively.
The main purpose of this is to enable centralized commenting of these important and tricky functions.
