This patch series introduces LPAE support for 32-bit ARM
platform.

I have test them on LPAE enabled kernel(command: kexec ... -d):

With this patch series:

crashkernel: [0x20000000 - 0x280fffff] (129M)
memory range: [0 - 0x1fffffff] (512M)
memory range: [0x28100000 - 0x3fffffff] (383M)
memory range: [0x1e0000000 - 0x1fcbfffff] (460M)

Without:

crashkernel: [0x20000000 - 0x280fffff] (129M)
memory range: [0 - 0x1fffffff] (512M)
memory range: [0x28100000 - 0x3fffffff] (383M)
memory range: [0xe0000000 - 0xfcbfffff] (460M)

Thanks,
Liu Hua
