[PATCH] x86_64: Move kernel to 2MB
Browse files Browse the repository at this point in the history
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
