Currently call_bind_status places a hard limit of 3 to the number of
retries on EACCES error. This limit was done to prevent NLM unlock
requests from being hang forever when the server keeps returning garbage.
However this change causes problem for cases when NLM service takes
longer than 9 seconds to register with the port mapper after a restart.
This patch removes this hard coded limit and let the RPC handles
the retry based on the standard hard/soft task semantics.

relaxed_ordering_read HCA capability is set if both the device supports
relaxed ordering (RO) read and RO is set in PCI config space.
RO in PCI config space can change during runtime. This will change the
value of relaxed_ordering_read HCA capability in FW, but the driver will
not see it since it queries the capabilities only once.
This can lead to the following scenario:
1. RO in PCI config space is enabled.
2. User creates MKey without RO.
3. RO in PCI config space is disabled.
As a result, relaxed_ordering_read HCA capability is turned off in FW
but remains on in driver copy of the capabilities.
4. User requests to reconfig the MKey with RO via UMR.
5. Driver will try to reconfig the MKey with RO read although it
shouldn't (as relaxed_ordering_read HCA capability is really off).
To fix this, check pcie_relaxed_ordering_enabled() before setting RO
read in UMR.

The reservedmem_of_init_fn's are invoked very early at boot before the
memory zones have even been defined. This makes it inappropriate to test
whether the page corresponding to a PFN is in ZONE_HIGHMEM from within
one.
Removing the check allows an ARM 32-bit kernel with SPARSEMEM enabled to
boot properly since otherwise we would be de-referencing an
uninitialized sparsemem map to perform pfn_to_page() check.
The arm64 architecture happens to work (and also has no high memory) but
other 32-bit architectures could also be having similar issues.
While it would be nice to provide early feedback about a reserved DMA
pool residing in highmem, it is not possible to do that until the first
time we try to use it, which is where the check is moved to.

With the addition of the V2 page table support, the domain page size
bitmap needs to be set prior to iommu core setting up direct mappings
for reserved regions. When reserved regions are mapped, if this is not
done, it will be looking at the V1 page size bitmap when determining
the page size to use in iommu_pgsize(). When it gets into the actual
amd mapping code, a check of see if the page size is supported can
fail, because at that point it is checking it against the V2 page size
bitmap which only supports 4K, 2M, and 1G.
Add a check to __iommu_domain_alloc() to not override the
bitmap if it was already set by the iommu ops domain_alloc() code path.

[ Upstream commit 00cbce5cbf88459cd1aa1d60d0f1df15477df127 ]
hfi1 user SDMA request processing has two bugs that can cause data
corruption for user SDMA requests that have multiple payload iovecs
where an iovec other than the tail iovec does not run up to the page
boundary for the buffer pointed to by that iovec.a
Here are the specific bugs:
1. user_sdma_txadd() does not use struct user_sdma_iovec->iov.iov_len.
Rather, user_sdma_txadd() will add up to PAGE_SIZE bytes from iovec
to the packet, even if some of those bytes are past
iovec->iov.iov_len and are thus not intended to be in the packet.
2. user_sdma_txadd() and user_sdma_send_pkts() fail to advance to the
next iovec in user_sdma_request->iovs when the current iovec
is not PAGE_SIZE and does not contain enough data to complete the
packet. The transmitted packet will contain the wrong data from the
iovec pages.
This has not been an issue with SDMA packets from hfi1 Verbs or PSM2
because they only produce iovecs that end short of PAGE_SIZE as the tail
iovec of an SDMA request.
Fixing these bugs exposes other bugs with the SDMA pin cache
(struct mmu_rb_handler) that get in way of supporting user SDMA requests
with multiple payload iovecs whose buffers do not end at PAGE_SIZE. So
this commit fixes those issues as well.
Here are the mmu_rb_handler bugs that non-PAGE_SIZE-end multi-iovec
payload user SDMA requests can hit:
1. Overlapping memory ranges in mmu_rb_handler will result in duplicate
pinnings.
2. When extending an existing mmu_rb_handler entry (struct mmu_rb_node),
the mmu_rb code (1) removes the existing entry under a lock, (2)
releases that lock, pins the new pages, (3) then reacquires the lock
to insert the extended mmu_rb_node.
If someone else comes in and inserts an overlapping entry between (2)
and (3), insert in (3) will fail.
The failure path code in this case unpins _all_ pages in either the
original mmu_rb_node or the new mmu_rb_node that was inserted between
(2) and (3).
3. In hfi1_mmu_rb_remove_unless_exact(), mmu_rb_node->refcount is
incremented outside of mmu_rb_handler->lock. As a result, mmu_rb_node
could be evicted by another thread that gets mmu_rb_handler->lock and
checks mmu_rb_node->refcount before mmu_rb_node->refcount is
incremented.
4. Related to #2 above, SDMA request submission failure path does not
check mmu_rb_node->refcount before freeing mmu_rb_node object.
If there are other SDMA requests in progress whose iovecs have
pointers to the now-freed mmu_rb_node(s), those pointers to the
now-freed mmu_rb nodes will be dereferenced when those SDMA requests
complete.

hfi1_mmu_rb_remove_unless_exact() did not move mmu_rb_node objects in
mmu_rb_handler->lru_list after getting a cache hit on an mmu_rb_node.
As a result, hfi1_mmu_rb_evict() was not guaranteed to evict truly
least-recently used nodes.
This could be a performance issue for an application when that
application:
- Uses some long-lived buffers frequently.
- Uses a large number of buffers once.
- Hits the mmu_rb_handler cache size or pinned-page limits, forcing
mmu_rb_handler cache entries to be evicted.
In this case, the one-time use buffers cause the long-lived buffer
entries to eventually filter to the end of the LRU list where
hfi1_mmu_rb_evict() will consider evicting a frequently-used long-lived
entry instead of evicting one of the one-time use entries.
Fix this by inserting new mmu_rb_node at the tail of
mmu_rb_handler->lru_list and move mmu_rb_ndoe to the tail of
mmu_rb_handler->lru_list when the mmu_rb_node is a hit in
hfi1_mmu_rb_remove_unless_exact(). Change hfi1_mmu_rb_evict() to evict
from the head of mmu_rb_handler->lru_list instead of the tail.

When the SOC approaches zero, an integer overflows in the columb
counter causing the driver to react poorly. This makes the driver
think it's at (above) the fully charged capacity when in fact it's
zero. It would then write this full capacity to NVRAM which would be
used on boot if the device remained off for less than 5 hours and
not plugged in.
This can be fixed and guarded against by doing the following:
- Changing the type of tmp in rk817_read_or_set_full_charge_on_boot()
to be an int instead of a u32. That way we can account for negative
numbers.
- Guard against negative values for the full charge on boot by setting
the charge to 0 if the system charge reports less than 0.
- Catch scenarios where the battery voltage is below the design
minimum voltage and set the system SOC to 0 at that time and update
the columb counter with a charge level of 0.
- Change the off time value from 5 hours to 30 minutes before we
recalculate the current capacity based on the OCV tables.
These changes allow the driver to operate better at low voltage/low
capacity conditions.

Label ATTR_ROOT in ntfs_read_mft() sets is_root = true and
ni->ni_flags |= NI_FLAG_DIR, then next attr will goto label ATTR_ALLOC
and alloc ni->dir.alloc_run. However two states are not always
consistent and can make memory leak.
1) attr_name in ATTR_ROOT does not fit the condition it will set
is_root = true but NI_FLAG_DIR is not set.
2) next attr_name in ATTR_ALLOC fits the condition and alloc
ni->dir.alloc_run
3) in cleanup function ni_clear(), when NI_FLAG_DIR is set, it frees
ni->dir.alloc_run, otherwise it frees ni->file.run
4) because NI_FLAG_DIR is not set in this case, ni->dir.alloc_run is
leaked as kmemleak reported:

[ Upstream commit 0e6255fa3f649170da6bd1a544680589cfae1131 ]
The VRTC alarm register can be programmed with an amount of seconds
after which the SoC will be woken up by the VRTC timer again. We are
already converting the alarm time from meson_vrtc_set_alarm() to
"seconds since 1970". This means we also need to use "seconds since
1970" for the current time.
This fixes a problem where setting the alarm to one minute in the future
results in the firmware (which handles wakeup) to output (on the serial
console) that the system will be woken up in billions of seconds.
ktime_get_raw_ts64() returns the time since boot, not since 1970. Switch
to ktime_get_real_ts64() to fix the calculation of the alarm time and to
make the SoC wake up at the specified date/time. Also the firmware
(which manages suspend) now prints either 59 or 60 seconds until wakeup
(depending on how long it takes for the system to enter suspend).

The workqueue watchdog prints a warning when there is no progress in
a worker pool. Where the progress means that the pool started processing
a pending work item.
Note that it is perfectly fine to process work items much longer.
The progress should be guaranteed by waking up or creating idle
workers.
show_one_worker_pool() prints state of non-idle worker pool. It shows
a delay since the last pool->watchdog_ts.
The timestamp is updated when a first pending work is queued in
__queue_work(). Also it is updated when a work is dequeued for
processing in worker_thread() and rescuer_thread().
The delay is misleading when there is no pending work item. In this
case it shows how long the last work item is being proceed. Show
zero instead. There is no stall if there is no pending work.
