In the quest to remove all stack VLA usage from the kernel[1], this
switches to using a stack size large enough for the saved routine and
adds a sanity check making sure the routine doesn't overflow into the
0x600 exception handler.

We use PHB in mode1 which uses bit 59 to select a correct DMA window.
However there is mode2 which uses bits 59:55 and allows up to 32 DMA
windows per a PE.
Even though documentation does not clearly specify that, it seems that
the actual hardware does not support bits 59:55 even in mode1, in other
words we can create a window as big as 1<<58 but DMA simply won't work.
This reduces the upper limit from 59 to 55 bits to let the userspace know
about the hardware limits.

Commit 59f47eff03 ("powerpc/pci: Use of_irq_parse_and_map_pci() helper")
removed the 'oirq' variable, but kept memsetting it when the DEBUG macro is
defined.
When setting DEBUG macro for debugging purpose, the kernel fails to build since
'oirq' is not defined anymore.
This patch simply remove the debug block, since it does not seem to sense
now.

Due to recent refactoring in EEH in:
commit b9fde58db7 ("powerpc/powernv: Rework EEH initialization on
powernv")
a misleading message was seen in the kernel message buffer:
[ 0.108431] EEH: PowerNV platform initialized
[ 0.589979] EEH: No capable adapters found
This happened due to the removal of the initialization delay for powernv
platform.
Even though the EEH infrastructure for the devices is eventually
initialized and still works just fine the eeh device probe step is
postponed in order to assure the PEs are created. Later
pnv_eeh_post_init does the probe devices job but at that point the
message was already shown right after eeh_init flow.
This patch introduces a new flag EEH_POSTPONED_PROBE to represent that
temporary state and avoid the message mentioned above and showing the
follow one instead:
[ 0.107724] EEH: PowerNV platform initialized
[ 4.844825] EEH: PCI Enhanced I/O Error Handling Enabled

According to kernel bisection, this problem became visible due to commit
f7f99100d8 ("mm: stop zeroing memory during allocation in vmemmap")
which changes how struct pages are initialized.
Memblock layout affects the pfn ranges covered by node/zone. Consider
that we have a VM with 2 NUMA nodes and each node has 4GB memory, and
the default (no memmap= given) memblock layout is like below:
MEMBLOCK configuration:
memory size = 0x00000001fff75c00 reserved size = 0x000000000300c000
memory.cnt = 0x4
memory[0x0] [0x0000000000001000-0x000000000009efff], 0x000000000009e000 bytes on node 0 flags: 0x0
memory[0x1] [0x0000000000100000-0x00000000bffd6fff], 0x00000000bfed7000 bytes on node 0 flags: 0x0
memory[0x2] [0x0000000100000000-0x000000013fffffff], 0x0000000040000000 bytes on node 0 flags: 0x0
memory[0x3] [0x0000000140000000-0x000000023fffffff], 0x0000000100000000 bytes on node 1 flags: 0x0
...
If you give memmap=1G!4G (so it just covers memory[0x2]),
the range [0x100000000-0x13fffffff] is gone:
MEMBLOCK configuration:
memory size = 0x00000001bff75c00 reserved size = 0x000000000300c000
memory.cnt = 0x3
memory[0x0] [0x0000000000001000-0x000000000009efff], 0x000000000009e000 bytes on node 0 flags: 0x0
memory[0x1] [0x0000000000100000-0x00000000bffd6fff], 0x00000000bfed7000 bytes on node 0 flags: 0x0
memory[0x2] [0x0000000140000000-0x000000023fffffff], 0x0000000100000000 bytes on node 1 flags: 0x0
...
This causes shrinking node 0's pfn range because it is calculated by the
address range of memblock.memory. So some of struct pages in the gap
range are left uninitialized.
We have a function zero_resv_unavail() which does zeroing the struct pages
within the reserved unavailable range (i.e. memblock.memory &&
!memblock.reserved). This patch utilizes it to cover all unavailable
ranges by putting them into memblock.reserved.

meson-gxl-mali.dtsi is only used on GXL SoCs. Thus it should use the GXL
specific compatible string instead of the GXBB one.
For now this is purely cosmetic since the (out-of-tree) lima driver for
this GPU currently uses the "arm,mali-450" match instead of the SoC
specific one. However, update the .dts to match the documentation since
this driver behavior might change in the future.

Like the odroid-c2 and wetek, the s400 uses the RTL8211F and seems to
suffer from the kind of stability issue.
Doing an iperf3 download test, we can see a significant number of LPI
interrupts on the tx path. After a short while (5 to 15 seconds), the
network connection dies. If using rootfs over NFS, the connection may
also break during the boot sequence.
We still don't have a real explanation for this problem so let's disable
EEE once again.

There is a problem with the sd-uhs mode when doing a soft reboot.
Switching back from 1.8v to 3.3v messes with the card, which no longer
respond (timeout errors). According to the specification, we should
perform a card reset (power cycling the card) but this is something we
cannot control on this design.
Then the only solution to restore the communication with the card is an
"unplug-plug" which is not acceptable
Until we find a solution, if any, disable the sd-uhs modes on this design.
For the people using uhs at the moment, there will a performance drop as
a result.

The implementation of flush_icache_range() includes instruction sequences
which are themselves patched at runtime, so it is not safe to call from
the patching framework.
This patch reworks the alternatives cache-flushing code so that it rolls
its own internal D-cache maintenance using DC CIVAC before invalidating
the entire I-cache after all alternatives have been applied at boot.
Modules don't cause any issues, since flush_icache_range() is safe to
call by the time they are loaded.

1ea66554d3 ("x86/mm: Mark p4d_offset() __always_inline")
046c0dbec0 ("x86: Mark native_set_p4d() as __always_inline")
p4d_offset(), native_set_p4d() and native_p4d_clear() were marked
__always_inline in attempt to move __pgtable_l5_enabled into __initdata
section.
It was required as KASAN initialization code is a user of
USE_EARLY_PGTABLE_L5, so all pgtable_l5_enabled() translated to
__pgtable_l5_enabled there. This includes pgtable_l5_enabled() called
from inline p4d helpers.
If compiler would decided to not inline these p4d helpers, but leave
them standalone, we end up with section mismatch.
We don't need __always_inline here anymore. __pgtable_l5_enabled moved
back to be __ro_after_init. See the following commit:
