commit fca8a117c1c9a0f8b8feed117db34cf58134dc2c upstream.
The rtc on the mox shares its interrupt line with the moxtet bus. Set
the interrupt type to be consistent between both devices. This ensures
correct setup of the interrupt line regardless of probing order.

[ Upstream commit 80df7d6af7f6d229b34cf237b2cc9024c07111cd ]
The zpci_get_max_write_size() helper is used to determine the maximum
size a PCI store or load can use at a given __iomem address.
For the PCI block store the following restrictions apply:
1. The dst + len must not cross a 4K boundary in the (pseudo-)MMIO space
2. len must not exceed ZPCI_MAX_WRITE_SIZE
3. len must be a multiple of 8 bytes
4. The src address must be double word (8 byte) aligned
5. The dst address must be double word (8 byte) aligned
Otherwise only a normal PCI store which takes its src value from
a register can be used. For these PCI store restriction 1 still applies.
Similarly 1 also applies to PCI loads.
It turns out zpci_max_write_size() instead implements stricter
conditions which prevents PCI block stores from being used where they
can and should be used. In particular instead of conditions 4 and 5 it
wrongly enforces both dst and src to be size aligned. This indirectly
covers condition 1 but also prevents many legal PCI block stores.
On top of the functional shortcomings the zpci_get_max_write_size() is
misnamed as it is used for both read and write size calculations. Rename
it to zpci_get_max_io_size() and implement the listed conditions
explicitly.

After unloading a module, we must reset the linear mapping permissions,
see the example below:
Before unloading a module:

0xffffaf809d6e1000-0xffffaf809d6e7000 0x000000011d6e1000 24K PTE . .. .. D A G . X . R V
After unloading a module:
0xffffaf809d65d000-0xffffaf809d6e1000 0x000000011d65d000 528K PTE . .. .. D A G . . W R V
0xffffaf809d6e1000-0xffffaf809d6e7000 0x000000011d6e1000 24K PTE . .. .. D A G . X W R V
The last mapping is not reset and we end up with WX mappings in the linear
mapping.
So add VM_FLUSH_RESET_PERMS to our module_alloc() definition.

[ Upstream commit 0f5cc249ff73552d3bd864e62f85841dafaa107d ]
max_low_pfn variable is incorrectly adjusted if the kernel is built with
high memory support and the later is detected in a running system, so the
memory which actually can be directly mapped is getting into the highmem
zone. See the ZONE_NORMAL range on my MIPS32r5 system:
> Zone ranges:
> DMA [mem 0x0000000000000000-0x0000000000ffffff]
> Normal [mem 0x0000000001000000-0x0000000007ffffff]
> HighMem [mem 0x0000000008000000-0x000000020fffffff]
while the zones are supposed to look as follows:
> Zone ranges:
> DMA [mem 0x0000000000000000-0x0000000000ffffff]
> Normal [mem 0x0000000001000000-0x000000001fffffff]
> HighMem [mem 0x0000000020000000-0x000000020fffffff]
Even though the physical memory within the range [0x08000000;0x20000000]
belongs to MMIO on our system, we don't really want it to be considered as
high memory since on MIPS32 that range still can be directly mapped.
Note there might be other problems caused by the max_low_pfn variable
misconfiguration. For instance high_memory variable is initialize with
virtual address corresponding to the max_low_pfn PFN, and by design it
must define the upper bound on direct map memory, then end of the normal
zone. That in its turn potentially may cause problems in accessing the
memory by means of the /dev/mem and /dev/kmem devices.
Let's fix the discovered misconfiguration then. It turns out the commit
a94e4f24ec83 ("MIPS: init: Drop boot_mem_map") didn't introduce the
max_low_pfn adjustment quite correct. If the kernel is built with high
memory support and the system is equipped with high memory, the
max_low_pfn variable will need to be initialized with PFN of the most
upper directly reachable memory address so the zone normal would be
correctly setup. On MIPS that PFN corresponds to PFN_DOWN(HIGHMEM_START).
If the system is built with no high memory support and one is detected in
the running system, we'll just need to adjust the max_pfn variable to
discard the found high memory from the system and leave the max_low_pfn as
is, since the later will be less than PFN_DOWN(HIGHMEM_START) anyway by
design of the for_each_memblock() loop performed a bit early in the
bootmem_init() method.

[ Upstream commit 0d0a3748a2cb38f9da1f08d357688ebd982eb788 ]
dmi_early_remap() has been defined as ioremap_cache() which on MIPS32 gets
to be converted to the VM-based mapping. DMI early remapping is performed
at the setup_arch() stage with no VM available. So calling the
dmi_early_remap() for MIPS32 causes the system to crash at the early boot
time. Fix that by converting dmi_early_remap() to the uncached remapping
which is always available on both 32 and 64-bits MIPS systems.
Note this change shall not cause any regressions on the current DMI
support implementation because on the early boot-up stage neither MIPS32
nor MIPS64 has the cacheable ioremapping support anyway.

commit ad362fe07fecf0aba839ff2cc59a3617bd42c33f upstream.
There is a potential UAF scenario in the case of an LPI translation
cache hit racing with an operation that invalidates the cache, such
as a DISCARD ITS command. The root of the problem is that
vgic_its_check_cache() does not elevate the refcount on the vgic_irq
before dropping the lock that serializes refcount changes.
Have vgic_its_check_cache() raise the refcount on the returned vgic_irq
and add the corresponding decrement after queueing the interrupt.

commit 7b95382f965133ef61ce44aaabc518c16eb46909 upstream.
When the VMM writes to ISPENDR0 to set the state pending state of
an SGI, we fail to convey this to the HW if this SGI is already
backed by a GICv4.1 vSGI.
This is a bit of a corner case, as this would only occur if the
vgic state is changed on an already running VM, but this can
apparently happen across a guest reset driven by the VMM.
Fix this by always writing out the pending_latch value to the
HW, and reseting it to false.

[ Upstream commit 7ac90b4cf107a3999b30844d7899e0331686b33b ]
On sc7180 when the watchdog timer fires your logs get filled with:
watchdog0: pretimeout event
watchdog0: pretimeout event
watchdog0: pretimeout event
...
watchdog0: pretimeout event
If you're using console-ramoops to debug crashes the above gets quite
annoying since it blows away any other log messages that might have
been there.
The issue is that the "bark" interrupt (AKA the "pretimeout"
interrupt) remains high until the watchdog is pet. Since we've got
things configured as "level" triggered we'll keep getting interrupted
over and over.
Let's switch to edge triggered. Now we'll get one interrupt when the
"bark" interrupt goes off and won't get another one until the "bark"
interrupt is cleared and asserts again.
This matches how many older Qualcomm SoCs have things configured.

[ Upstream commit b57160859263c083c49482b0d083a586b1517f78 ]
DSS irq trigger type is set to IRQ_TYPE_EDGE_RISING in the DT file, but
the TRM says it is level triggered.
For some reason triggering on rising edge results in double the amount
of expected interrupts, e.g. for normal page flipping test the number of
interrupts per second is 2 * fps. It is as if the IRQ triggers on both
edges. There are no other side effects to this issue than slightly
increased CPU & power consumption due to the extra interrupt.
Switching to IRQ_TYPE_LEVEL_HIGH is correct and fixes the issue, so
let's do that.

[ Upstream commit bd68ffce69f6cf8ddd3a3c32549d1d2275e49fc5 ]
dlpar_memory_remove_by_index() may access beyond the bounds of the
drmem lmb array when the LMB lookup fails to match an entry with the
given DRC index. When the search fails, the cursor is left pointing to
&drmem_info->lmbs[drmem_info->n_lmbs], which is one element past the
last valid entry in the array. The debug message at the end of the
function then dereferences this pointer:
pr_debug("Failed to hot-remove memory at %llx\n",
lmb->base_addr);
This was found by inspection and confirmed with KASAN:
