Diff to previous 1.98 (colored)

Mirror what is done for amd64 boot and ACPI wakeup code by setting
CR0_WP (write protection bit) early on boot. Although it is set later via
cpu_init(), this can help tracking down invalid writes to pages mapped
as read only from ring 0.

No regression observed when booting under anita (QEMU) or a P4 host.

Depending on your hardware or setup, you may trigger code paths I have
overlooked. So if your machine does not start properly, or you get
page faults early during boot, please report them to me.

This form allows you to request diff's between any two revisions of a file. You may select a symbolic revision name using the selection box or you may type in a numeric name using the type-in text box.
