[PATCH] x86_64: Move kernel to 2MB
As suggested by Andi (and Alan), move the default kernel location from 1Mb to 2Mb, to align to the start of a TLB entry. Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

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
