Subject: Handle kernelcore= boot parameter in common code to avoid boot problem on IA64
From: Yasunori Goto <y-goto@xxxxxxxxxxxxxx>
When "kernelcore" boot option is specified, kernel can't boot up on ia64
because of an infinite loop. In addition, the parsing code can be handled
in an architecture-independent manner.
This patch patches uses common code to handle the kernelcore= parameter.
It is only available to architectures that support arch-independent
zone-sizing (i.e. define CONFIG_ARCH_POPULATES_NODE_MAP). Other
architectures will ignore the boot parameter.
This effectively removes the following arch-specific patches;
ia64-specify-amount-of-kernel-memory-at-boot-time.patch
ppc-and-powerpc-specify-amount-of-kernel-memory-at-boot-time.patch
x86_64-specify-amount-of-kernel-memory-at-boot-time.patch
x86-specify-amount-of-kernel-memory-at-boot-time.patch
