Nice...
#define KERNELBASE ASM_CONST(CONFIG_KERNEL_START)
#define PAGE_OFFSET ASM_CONST(CONFIG_PAGE_OFFSET)
+#define LOAD_OFFSET ASM_CONST((CONFIG_KERNEL_START-
CONFIG_PHYSICAL_START))
I think this should be CONFIG_PAGE_OFFSET - CONFIG_PHYSICAL_START
though.
Disagree (assuming I'm thinking straight first thing in the morning).
PAGE_OFFSET is virt address of the beginning of memory, where
KERNEL_START is virt address of start of kernel text.
PHYSICAL_START is physical address of KERNEL_START.
(I tried to match x86's definitions here as per Milton's request to be
consistent).
