[PATCH 1/2] memory_hotplug: Add a bounds check to check_hotplug_memory_range()

2019-09-09 Thread Alastair D'Silva
From: Alastair D'Silva On PowerPC, the address ranges allocated to OpenCAPI LPC memory are allocated from firmware. These address ranges may be higher than what older kernels permit, as we increased the maximum permissable address in commit 4ffe713b7587 ("powerpc/mm: Increase the max addressable
