Newer UC-Logic tablets, such as ones made by Huion have stopped
reporting in-range state, but they're otherwise worthy tablets. The
manufacturer was notified of the problem and promised to fix this in the
future. Meanwhile, detect pen coming in range, and emulate the reports
to the userspace, to make the tablets useable.

Re-initialize UC-Logic tablets on resume. UC-Logic tablet initialization

simply discard the retrieved parameters after initialization.

Refactor and extract UC-Logic tablet initialization and parameter
discovery into a module. For these tablets, the major part of parameter
discovery cannot be separated from initialization so they have to be in
the same module. Define explicitly and clearly what possible quirks the
tablets may have to make the driver implementation easier and simpler.

A call of pci_iounmap() call without CONFIG_PCI leads to a build error
on some architectures. We tried to address this and add a check of
IS_ENABLED(CONFIG_PCI), but this still doesn't seem enough for sh.
Ideally we should fix it globally, it's really a corner case, so let's
paper over it with a simpler ifdef.

It is normal user behaviour to start, stop, then start a stream
again without closing it. Currently this works for compressed
playback streams but not capture ones.
The states on a compressed capture stream go directly from OPEN to
PREPARED, unlike a playback stream which moves to SETUP and waits
for a write of data before moving to PREPARED. Currently however,
when a stop is sent the state is set to SETUP for both types of
streams. This leaves a capture stream in the situation where a new
start can't be sent as that requires the state to be PREPARED and
a new set_params can't be sent as that requires the state to be
OPEN. The only option being to close the stream, and then reopen.
Correct this issues by allowing snd_compr_drain_notify to set the
state depending on the stream direction, as we already do in
set_params.

When reading 'efi_page_tables' debugfs triggers an out-of-bounds access here:
arch/arm64/mm/dump.c: 282
if (addr >= st->marker[1].start_address) {
called from:
arch/arm64/mm/dump.c: 331
note_page(st, addr, 2, pud_val(pud));
because st->marker++ is is called after "UEFI runtime end" which is the
last element in addr_marker[]. Therefore, add a terminator like the one
for kernel_page_tables, so it can be skipped to print out non-existent
markers.

that is also associated with containers, cgroups etc. This can easily
cause confusion.
Make the user prompt more specific. Match the config symbol name.

Pull arm64 fixes from Will Deacon:
"Although we're still debugging a few minor arm64-specific issues in
mainline, I didn't want to hold this lot up in the meantime.
We've got an additional KASLR fix after the previous one wasn't quite
complete, a fix for a performance regression when mapping executable
pages into userspace and some fixes for kprobe blacklisting. All
candidates for stable.
Summary:
- Fix module loading when KASLR is configured but disabled at runtime
- Fix accidental IPI when mapping user executable pages
- Ensure hyp-stub and KVM world switch code cannot be kprobed"

arm64: hibernate: Clean the __hyp_text to PoC after resume
arm64: hyp-stub: Forbid kprobing of the hyp-stub
arm64: kprobe: Always blacklist the KVM world-switch code
arm64: kaslr: ensure randomized quantities are clean also when kaslr is off

In autofs_fill_super() on error of get inode/make root dentry the return
should be ENOMEM as this is the only failure case of the called
functions.

autofs_expire_run() calls dput(dentry) to drop the reference count of
dentry. However, dentry is read via autofs_dentry_ino(dentry) after
that. This may result in a use-free-bug. The patch drops the reference
count of dentry only when it is never used.

When superblock has lots of inodes without any pagecache (like is the
case for /proc), drop_pagecache_sb() will iterate through all of them
without dropping sb->s_inode_list_lock which can lead to softlockups
(one of our customers hit this).
Fix the problem by going to the slow path and doing cond_resched() in
case the process needs rescheduling.
