As I am working on SPARSE_IRQ a number of implicit resource
grabs in the kernel become evident. For example, some includes
like <linux/irqs.h> would implicitly include <mach/irqs.h>
and then from there <mach/db8500-regs.h>.
In many cases it is masking the fact that drivers do not
properly use resources to pass their dependencies, base
addresses etc. So write explicit #include statements with
TODO items to have this fixed the proper way to all drivers
doing this.

Add time keeping code for metag. Meta hardware threads have 2 timers.
The background timer (TXTIMER) is used as a free-running time base, and
the interrupt timer (TXTIMERI) is used for the timer interrupt. Both
counters traditionally count at approximately 1MHz.

Don Morris reproduced on a HP z620 workstation, and bisected it to
commit e8d195525809 ("acpi, memory-hotplug: parse SRAT before memblock
is ready")
It turns out movable_map has some problems, and it breaks several things
1. numa_init is called several times, NOT just for srat. so those
nodes_clear(numa_nodes_parsed)
memset(&numa_meminfo, 0, sizeof(numa_meminfo))
can not be just removed. Need to consider sequence is: numaq, srat, amd, dummy.
and make fall back path working.
2. simply split acpi_numa_init to early_parse_srat.
a. that early_parse_srat is NOT called for ia64, so you break ia64.
b. for (i = 0; i < MAX_LOCAL_APIC; i++)
set_apicid_to_node(i, NUMA_NO_NODE)
still left in numa_init. So it will just clear result from early_parse_srat.
it should be moved before that....
c. it breaks ACPI_TABLE_OVERIDE...as the acpi table scan is moved
early before override from INITRD is settled.
3. that patch TITLE is total misleading, there is NO x86 in the title,
but it changes critical x86 code. It caused x86 guys did not
pay attention to find the problem early. Those patches really should
be routed via tip/x86/mm.
4. after that commit, following range can not use movable ram:
a. real_mode code.... well..funny, legacy Node0 [0,1M) could be hot-removed?
b. initrd... it will be freed after booting, so it could be on movable...
c. crashkernel for kdump...: looks like we can not put kdump kernel above 4G
anymore.
d. init_mem_mapping: can not put page table high anymore.
e. initmem_init: vmemmap can not be high local node anymore. That is
not good.
If node is hotplugable, the mem related range like page table and
vmemmap could be on the that node without problem and should be on that
node.
We have workaround patch that could fix some problems, but some can not
be fixed.
So just remove that offending commit and related ones including:
f7210e6c4ac7 ("mm/memblock.c: use CONFIG_HAVE_MEMBLOCK_NODE_MAP to
protect movablecore_map in memblock_overlaps_region().")
01a178a94e8e ("acpi, memory-hotplug: support getting hotplug info from
SRAT")
27168d38fa20 ("acpi, memory-hotplug: extend movablemem_map ranges to
the end of node")
e8d195525809 ("acpi, memory-hotplug: parse SRAT before memblock is
ready")
fb06bc8e5f42 ("page_alloc: bootmem limit with movablecore_map")
42f47e27e761 ("page_alloc: make movablemem_map have higher priority")
6981ec31146c ("page_alloc: introduce zone_movable_limit[] to keep
movable limit for nodes")
34b71f1e04fc ("page_alloc: add movable_memmap kernel parameter")
4d59a75125d5 ("x86: get pg_data_t's memory from other node")
Later we should have patches that will make sure kernel put page table
and vmemmap on local node ram instead of push them down to node0. Also
need to find way to put other kernel used ram to local node ram.
