We don't want to fall through to a bunch of errors for retention
|
||||
if PM_OMAP4_CPU_OSWR_DISABLE is not configured for a SoC.

|
||||
|
||||
There is a memory setup problem on ThunderX systems with certain
|
||||
memory configurations. The symptom is
|
||||
|
||||
kernel BUG at mm/page_alloc.c:1848!
|
||||
|
||||
This happens for some configs with 64k page size enabled. The bug
|
||||
triggers for page zones with some pages in the zone not assigned to
|
||||
this particular zone. In my case some pages that are marked as nomap
|
||||
were not reassigned to the new zone of node 1, so those are still
|
||||
assigned to node 0.
|
||||
|
||||
The reason for the mis-configuration is a change in pfn_valid() which
|
||||
reports pages marked nomap as invalid:
|
||||
|
||||
68709f45385a arm64: only consider memblocks with NOMAP cleared for linear mapping
|
||||
|
||||
This causes pages marked as nomap being no long reassigned to the new
|
||||
zone in memmap_init_zone() by calling __init_single_pfn().
|
||||
|
||||
Fixing this by restoring the old behavior of pfn_valid() to use
|
||||
memblock_is_memory(). Also changing users of pfn_valid() in arm64 code
|
||||
to use memblock_is_map_memory() where necessary. This only affects
|
||||
code in ioremap.c. The code in mmu.c still can use the new version of
|
||||
pfn_valid().
|
||||
|
||||
Should be marked stable v4.5..
