There is a lot of common code in find_get_entries(),
find_get_pages_range() and find_get_pages_range_tag(). Factor out
find_get_entry() which simplifies all three functions.

The comment shows that the reason for using find_get_entries() is now
stale; find_get_pages() will not return 0 if it hits a consecutive run of
swap entries, and I don't believe it has since 2011. pagevec_lookup() is
a simpler function to use than find_get_pages(), so use it instead.

Patch series "Overhaul multi-page lookups for THP", v4.
This THP prep patchset changes several page cache iteration APIs to only
return head pages.
- It's only possible to tag head pages in the page cache, so only
return head pages, not all their subpages.
- Factor a lot of common code out of the various batch lookup routines
- Add mapping_seek_hole_data()
- Unify find_get_entries() and pagevec_lookup_entries()
- Make find_get_entries only return head pages, like find_get_entry().
These are only loosely connected, but they seem to make sense together as
a series.
This patch (of 14):
Pagecache tags are used for dirty page writeback. Since dirtiness is
tracked on a per-THP basis, we only want to return the head page rather
than each subpage of a tagged page. All the filesystems which use huge
pages today are in-memory, so there are no tagged huge pages today.

The size of the buffer being bounced is not checked if it happens
to be larger than the size of the mapped buffer. Because the size
can be controlled by a device, as it's the case with virtio devices,
this can lead to memory corruption.
This patch saves the remaining buffer memory for each slab and uses
that information for validation in the sync/unmap paths before
swiotlb_bounce is called.
Validating this argument is important under the threat models of
AMD SEV-SNP and Intel TDX, where the HV is considered untrusted.

The PRP addressing scheme requires all PRP entries except for the
first one to have a zero offset into the NVMe controller pages (which
can be different from the Linux PAGE_SIZE). Use the min_align_mask
device parameter to ensure that swiotlb does not change the address
of the buffer modulo the device page size to ensure that the PRPs
won't be malformed.

Respect the min_align_mask in struct device_dma_parameters in swiotlb.
There are two parts to it:
1) for the lower bits of the alignment inside the io tlb slot, just
extent the size of the allocation and leave the start of the slot
empty
2) for the high bits ensure we find a slot that matches the high bits
of the alignment to avoid wasting too much memory

There are many places where the pattern kmap/memcpy/kunmap occurs.
This pattern was lifted to the core common functions
memcpy_[to|from]_page().
Use these new functions to reduce the code, eliminate direct uses of
kmap, and leverage the new core functions use of kmap_local_page().
Also, there is 1 place where a kmap/memcpy is followed by an
optional memset. Here we leave the kmap open coded to avoid remapping
the page but use kmap_local_page() directly.

Check that PML is actually enabled before setting the mask to force a
SPTE to be write-protected. The bits used for the !AD_ENABLED case are
in the upper half of the SPTE. With 64-bit paging and EPT, these bits
are ignored, but with 32-bit PAE paging they are reserved. Setting them
for L2 SPTEs without checking PML breaks NPT on 32-bit KVM.

Instead of 'make distclean', 'make clean' should remove build artifacts
unneeded by external module builds. Obviously, you do not need to keep
this directory.

Commit 209b44c804c ("docs: powerpc: syscall64-abi.rst: fix a malformed
table") attempted to fix the formatting of tables in syscall64-abi.rst, but
inadvertently changed some register names.
Redo the tables with the correct register names, and while we're here,
clean things up to separate the registers into different rows and add
headings.

resolution
Some servers seem to mistakenly report different values for
capabilities and share flags, so we can't always rely on those values
to decide whether the resolved target can handle any new DFS
referrals.
Add a new helper is_referral_server() to check if all resolved targets
can handle new DFS referrals by directly looking at the
GET_DFS_REFERRAL.ReferralHeaderFlags value as specified in MS-DFSC
2.2.4 RESP_GET_DFS_REFERRAL in addition to is_tcon_dfs().

Handle the case where a resolved target share is like
//server/users/dir, and the user "foo" has no read permission to
access the parent folder "users" but has access to the final path
component "dir".
is_path_remote() already implements that, so call it directly.

fs context in order to get new connection to server, so clone the
original context and change it accordingly when retrying the DFS

UNC, prefix path and ip address.
