Subject: [PATCH 0/3] sp0, ss1, and sp1 docs and minor fixes
Date: Tue, 10 Mar 2015 11:05:57 -0700	[thread overview]
Message-ID: <cover.1426009661.git.luto@amacapital.net> (raw)

This documents things, clarifies the code, and fixes an apparently
inconsequential bug that caused the init sp0 to be wrong.

(My earlier 32-bit bug was caused because I thought that the code
I'm fixing was correct.  Whoops.)

Andy Lutomirski (3):
  x86: Create and use a TOP_OF_KERNEL_STACK_PADDING macro
  x86: Unify and fix init sp0
  x86_32: Document our abuse of ss1 and sp1
