[PATCH 00/02] kexec: Move segment code to assembly files

[Magnus Damm]

kexec: Move segment code to assembly files

The following patches rearrange the lowlevel kexec code to perform idt,
gdt and segment setup code in assembly on the code page instead of doing 
it in inline assembly in the C files.

Our dom0 Xen port of kexec and kdump executes the code page from the 
hypervisor when kexec:ing into a new kernel. Putting as much code as
possible on the code page allows us to keep the amount of duplicated 
code low.

These patches are part of the Xen port of kexec and kdump which recently 
has been accepted into the xen-unstable.hg tree. Sending them upstream
now is an attempt to simplify future porting work.
