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
