[Patch 3/4] Move the base kernel to 2Mb to align with TLBboundaries

From: Arjan van de Ven
Date: Mon Feb 27 2006 - 10:31:08 EST


As suggested by Andi (and Alan), move the default kernel location
from 1Mb to 2Mb, to align to the start of a TLB entry.

This gives the physical address where the kernel is loaded. Normally
- for regular kernels this value is 0x100000 (1MB). But in the case
+ for regular kernels this value is 0x200000 (2MB). But in the case
of kexec on panic the fail safe kernel needs to run at a different
address than the panic-ed kernel. This option is used to set the load
address for kernels used to capture crash dump on being kexec'ed
