History
Linus Torvalds 40c93d7fff Two X86 fixes: 
- Move the command line preparation and the early command line parsing
    earlier so that the command line parameters which affect
    early_reserve_memory(), e.g. efi=nosftreserve, are taken into
    account. This was broken when the invocation of early_reserve_memory()
    was moved recently.
 
  - Use an atomic type for the SGX page accounting, which is read and
    written lockless, to plug various race conditions related to it.
