staging: comedi: daqboard2000: use pci_id_table 'driver_data'
The driver's COMEDI "auto-attach" handler `db2k_auto_attach()` calls
`db2k_find_boardinfo()` to find an element of our board information
array `db2k_boardtypes[]` that matches the probed PCI device. The
driver's PCI device table matches several boards in the DaqBoard/2000
series that match a single PCI vendor and device ID combination.
`db2k_find_boardinfo()` uses the probed PCI device's subvendor and
subdevice IDs to find the matching board information, returning `NULL`
for no match.
Change the driver's PCI device table `db2k_pci_table[]` to match
supported PCI vendor, device, subvendor and subdevice IDs, and set the
`.driver_data` member of each element to the index of the matching
element of `db2k_boardtypes[]`. That index gets passed through to the
COMEDI auto-attach handler `db2k_auto_attach()`. Use it to index
directly into `db2k_boardtypes[]` instead of calling
`db2k_find_boardinfo()` to find the match.
Use array index designators in the initializer of `db2k_boardtypes[]`.
Use enumerated constants defined by new type `enum db2k_boardids` to
name the board type indices.
The `id` member of `struct db2k_boardtype` is no longer used, so remove
it. Also remove the subdevice ID macros `DB2K_SUBSYSTEM_IDS2` and
`DB2K_SUBSYSTEM_IDS4` as the subdevice IDs are now specified as numbers
in the PCI device table. Remove `db2k_find_boardinfo()` as it is no
longer used.

mm: workingset: fix use-after-free in shadow node shrinker
Several people report seeing warnings about inconsistent radix tree
nodes followed by crashes in the workingset code, which all looked like
use-after-free access from the shadow node shrinker.
Dave Jones managed to reproduce the issue with a debug patch applied,
which confirmed that the radix tree shrinking indeed frees shadow nodes
while they are still linked to the shadow LRU:
This is the WARN_ON_ONCE(!list_empty(&node->private_list)) placed in the
inlined radix_tree_shrink().
The problem is with 14b468791fa9 ("mm: workingset: move shadow entry
tracking to radix tree exceptional tracking"), which passes an update
callback into the radix tree to link and unlink shadow leaf nodes when
tree entries change, but forgot to pass the callback when reclaiming a
shadow node.
While the reclaimed shadow node itself is unlinked by the shrinker, its
deletion from the tree can cause the left-most leaf node in the tree to
be shrunk. If that happens to be a shadow node as well, we don't unlink
it from the LRU as we should.
Consider this tree, where the s are shadow entries:
root->rnode
|
[0 n]
| |
[s ] [sssss]
Now the shadow node shrinker reclaims the rightmost leaf node through
the shadow node LRU:
root->rnode
|
[0 ]
|
[s ]
Because the parent of the deleted node is the first level below the
root and has only one child in the left-most slot, the intermediate
level is shrunk and the node containing the single shadow is put in
its place:
root->rnode
|
[s ]
The shrinker again sees a single left-most slot in a first level node
and thus decides to store the shadow in root->rnode directly and free
the node - which is a leaf node on the shadow node LRU.
root->rnode
|
s
Without the update callback, the freed node remains on the shadow LRU,
where it causes later shrinker runs to crash.
Pass the node updater callback into __radix_tree_delete_node() in case
the deletion causes the left-most branch in the tree to collapse too.
Also add warnings when linked nodes are freed right away, rather than
wait for the use-after-free when the list is scanned much later.

mm: stop leaking PageTables
4.10-rc loadtest (even on x86, and even without THPCache) fails with
"fork: Cannot allocate memory" or some such; and /proc/meminfo shows
PageTables growing.
Commit 953c66c2b22a ("mm: THP page cache support for ppc64") that got
merged in rc1 removed the freeing of an unused preallocated pagetable
after do_fault_around() has called map_pages().
This is usually a good optimization, so that the followup doesn't have
to reallocate one; but it's not sufficient to shift the freeing into
alloc_set_pte(), since there are failure cases (most commonly
VM_FAULT_RETRY) which never reach finish_fault().
Check and free it at the outer level in do_fault(), then we don't need
to worry in alloc_set_pte(), and can restore that to how it was (I
cannot find any reason to pte_free() under lock as it was doing).
And fix a separate pagetable leak, or crash, introduced by the same
change, that could only show up on some ppc64: why does do_set_pmd()'s
failure case attempt to withdraw a pagetable when it never deposited
one, at the same time overwriting (so leaking) the vmf->prealloc_pte?
Residue of an earlier implementation, perhaps? Delete it.

staging: gdm724x: update HCI structs with new bitwise types
Update the driver's HCI structs and associated endian-converter
functions with new driver-specific bitwise types. The new types
encourage correct endian-handling within the driver by triggering
sparse warnings when mixing with other types. The driver's
endian-converters provide correct and warning-free conversions.
Driver-specific bitwise types are used instead of the standard
endian-specific types because the attached device can be of either
endian. This is also why the driver has its own endian-conversion
functions, which consider endianness of both the cpu and the attached
device.
Introducing the new types to the converters fixes the sparse warnings:
