Raghu noticed an issue with excessive memory allocation on power with a
simple cgroup test, specifically, in mem_cgroup_css_alloc ->
for_each_node -> alloc_mem_cgroup_per_zone_info(), which ends up blowing
up the kmalloc-2048 slab (to the order of 200MB for 400 cgroup
directories).
The underlying issue is that NODES_SHIFT on power is 8 (256 NUMA nodes
possible), which defines node_possible_map, which in turn defines the
value of nr_node_ids in setup_nr_node_ids and the iteration of
for_each_node.
In practice, we never see a system with 256 NUMA nodes, and in fact, we
do not support node hotplug on power in the first place, so the nodes
that are online when we come up are the nodes that will be present for
the lifetime of this kernel. So let's, at least, drop the NUMA possible
map down to the online map at runtime. This is similar to what x86 does
in its initialization routines.
mem_cgroup_css_alloc should also be fixed to only iterate over
memory-populated nodes and handle hotplug, but that is a separate
change.

This patch changes the name of the make variable TARGETS, to prevent it
from colliding with a value set by the user on the command line (as they

The goal is to verify vphn_unpack_associativity() parses VPHN numbers
correctly. We feed it with a variety of input values and compare with
expected results.
PAPR+ does not say much about VPHN parsing: I came up with a list of
tests that check many simple cases and some corner ones. I wouldn't
dare to say the list is exhaustive though.

The current VPHN parsing logic has some flaws that this patch aims to fix:
1) when the value 0xffff is read, the value 0xffffffff gets added to the
the output list and its element count isn't incremented. This is wrong.
According to PAPR+ the domain identifiers are packed into a sequence
terminated by the "reserved value of all ones". This means that 0xffff
is a stream terminator.
2) the combination of byteswaps and casts make the code hardly readable.
Let's parse the stream one 16-bit field at a time instead.
3) it is assumed that the hypercall returns 12 32-bit values packed into
6 64-bit registers. According to PAPR+, the domain identifiers may be
streamed as 16-bit values. Let's increase the number of expected numbers
to 24.

We have set CONFIG_PPC_OF to always 'y' in commit 0a498d96a332
("powerpc: set CONFIG_PPC_OF=y always for ARCH=powerpc") nine years
ago. And the arch/ppc also has gone away for many years. The OF
functionality was also moved to a common place and be used by many
archs. So it does make no sense to keep such a option in the current
kernel. Just kill it.

The flush_tlb hook in cpu_spec was introduced as a generic function hook
to invalidate TLBs. But the current implementation of flush_tlb hook
takes IS (invalidation selector) as an argument which is architecture
dependent. Hence, It is not right to have a generic routine where caller
has to pass non-generic argument.
This patch fixes this and makes flush_tlb hook as high level API.

Currently, a 64-bit little-endian zImage.epapr won't boot in epapr mode,
as we never return from platform_init.
Before entering C, we initialise our stack by setting r1 16 bytes below
the end of the _bss_stack:
stwu r0,-16(r1) /* establish a stack frame */
However, the called function will save the caller's lr in the caller's
frame's lr save area, at -16(r1) to -32(r1).
This means that writes to the fdt variable will corrupt the saved link
register:
0000000020c06018 l O .bss 0000000000001000 _bss_stack
0000000020c07018 l O .bss 0000000000000008 fdt
We'll need at least 32 bytes in the initial stack frame, to handle the
LR save area. We bump this to 112 bytes, as that'll be the max required
by ABIv1.
Thanks to Alistair Popple for debugging help.

Drop unused fsl_mpic_primary_get_version(), mpic_set_clk_ratio(),
mpic_set_serial_int().
+ fsl_mpic_primary_get_version() is just a safe wrapper around
fsl_mpic_get_version() for SMP configurations. While the latter is
called explicitly for handling PIC initialization and setting up error
interrupt vector depending on PIC hardware version, the former isn't
used for anything.
+ As for mpic_set_clk_ratio() and mpic_set_serial_int(), they both are
almost nine years old[1] but still have no chance to be called even from
out-of-tree modules because they both are __init and of course aren't
exported.

This removes definitions in opal-api.h that are completely unused in
Linux.
For each of these I see three possibilities, 1) we *should* be using
them in Linux and patches will arrive to do that, 2) they are not used
but should stay in the header to document the API for some important
reason, 3) they are not used and needn't be part of the API.

This commit gets opal-api.h to mostly match the version in Skiboot as of
commit ea7d806ab0ba.
The exceptions are things which are not (currently) used in Linux.
Most of this is just whitespace and a few things moving around. I think
the diff is readable.
Also OpalMessageType became opal_msg_type, requiring a change in the
Linux code.
Finally Skiboot and Linux disagree on CAPI vs CXL, because CAPI means
something else in Linux. To handle that we just point the Linux wrapper,
which is named "cxl" to the OPAL token OPAL_PCI_SET_PHB_CAPI_MODE.

Pull arm64 fixes from Catalin Marinas:
- add TLB invalidation for page table tear-down which was missed when
support for CONFIG_HAVE_RCU_TABLE_FREE was added (assuming page table
freeing was always deferred)
- use UEFI for system and reset poweroff if available
- fix asm label placement in relation to the alignment statement
* tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux:
arm64: put __boot_cpu_mode label after alignment instead of before
efi/arm64: use UEFI for system reset and poweroff
arm64: Invalidate the TLB corresponding to intermediate page table levels
