dmaengine: ioat: Allocate correct size for descriptor chunk

with IOAT_CHUNK_SIZE. Recently, IOAT_CHUNK_SIZE was reduced to 512M but
the allocation did not change. To fix, change to using the

dmaengine: dma-jz4780: Fix race in jz4780_dma_tx_status
The jz4780_dma_tx_status() function would check if a channel's cookie
state was set to 'completed', and if not, it would enter the critical
section. However, in that time frame, the jz4780_dma_chan_irq() function
was able to set the cookie to 'completed', and clear the jzchan->vchan
pointer, which was deferenced in the critical section of the first
function.
Fix this race by checking the channel's cookie state after entering the
critical function and not before.

dmaengine: dmatest: Prevent to run on misconfigured channel
Andy reported that commit 6b41030fdc79 ("dmaengine: dmatest:
Restore default for channel") broke his scripts for the case
where "busy" channel is used for configuration with expectation
that run command would do nothing. Instead, behavior was
(unintentionally) changed to treat such case as under-configuration
and progress with defaults, i.e. run command would start a test
with default setting for channel (which would use all channels).
Restore original behavior with tracking status of channel setter
so we can distinguish between misconfigured and under-configured
cases in run command and act accordingly.

Now the K3 UDMA glue layer enable functions perform RMW operation on UDMA
RX/TX RT_CTL registers to set EN bit and enable channel, which is
incorrect, because only EN bit has to be set in those registers to enable
channel (all other bits should be cleared 0).
More over, this causes issues when bootloader leaves UDMA channel RX/TX
RT_CTL registers in incorrect state - TDOWN bit set, for example. As
result, UDMA channel will just perform teardown right after it's enabled.
Hence, fix it by writing correct values (EN=1) directly in UDMA channel
RX/TX RT_CTL registers in k3_udma_glue_enable_tx/rx_chn() functions.

mm/hugetlb: try preferred node first when alloc gigantic page from cma
Since commit cf11e85fc08c ("mm: hugetlb: optionally allocate gigantic
hugepages using cma"), the gigantic page would be allocated from node
which is not the preferred node, although there are pages available from
that node. The reason is that the nid parameter has been ignored in
alloc_gigantic_page().
Besides, the __GFP_THISNODE also need be checked if user required to
alloc only from the preferred node.
After this patch, the preferred node is tried first before other allowed
nodes, and don't try to allocate from other nodes if __GFP_THISNODE is
specified. If user don't specify the preferred node, the current node
will be used as preferred node, which makes sure consistent behavior of
allocating gigantic and non-gigantic hugetlb page.

mm/rmap: fixup copying of soft dirty and uffd ptes
During memory migration a pte is temporarily replaced with a migration
swap pte. Some pte bits from the existing mapping such as the soft-dirty
and uffd write-protect bits are preserved by copying these to the
temporary migration swap pte.
However these bits are not stored at the same location for swap and
non-swap ptes. Therefore testing these bits requires using the
appropriate helper function for the given pte type.
Unfortunately several code locations were found where the wrong helper
function is being used to test soft_dirty and uffd_wp bits which leads to
them getting incorrectly set or cleared during page-migration.
Fix these by using the correct tests based on pte type.

checkpatch: fix the usage of capture group ( ... )
The usage of "capture group (...)" in the immediate condition after `&&`
results in `$1` being uninitialized. This issues a warning "Use of
uninitialized value $1 in regexp compilation at ./scripts/checkpatch.pl
line 2638".
I noticed this bug while running checkpatch on the set of commits from
v5.7 to v5.8-rc1 of the kernel on the commits with a diff content in
their commit message.
This bug was introduced in the script by commit e518e9a59ec3
("checkpatch: emit an error when there's a diff in a changelog"). It
has been in the script since then.
The author intended to store the match made by capture group in variable
`$1`. This should have contained the name of the file as `[\w/]+`
matched. However, this couldn't be accomplished due to usage of capture
group and `$1` in the same regular expression.
Fix this by placing the capture group in the condition before `&&`.
Thus, `$1` can be initialized to the text that capture group matches
thereby setting it to the desired and required value.

mm: track page table modifications in __apply_to_page_range()
__apply_to_page_range() is also used to change and/or allocate
page-table pages in the vmalloc area of the address space. Make sure
these changes get synchronized to other page-tables in the system by
calling arch_sync_kernel_mappings() when necessary.
The impact appears limited to x86-32, where apply_to_page_range may miss
updating the PMD. That leads to explosions in drivers like
Nominate Nathan and myself to be point of contact for clang/LLVM related
support, after a poll at the LLVM BoF at Linux Plumbers Conf 2020.
While corporate sponsorship is beneficial, its important to not entrust
the keys to the nukes with any one entity. Should Nathan and I find
