all the drivers sharing register map with mlx-platform.
Extend register map configuration with the sets of writable, readable and
volatile registers to allow verification prior to the access. It prevents
unexpected access to hardware registers by the drivers, sharing register
map with mlx-platform.
Extend register map configuration with cache type field in order to have
ability to cache hardware register value, where possible. Use simple flat
array type for register lookups, which is most suitable in case when the
number of the registers is not too large.
Add at the end of probing routine calls to regcache_mark_dirty and

Commit 4eebd5a4e7 ("apple-gmux: lock iGP IO to protect from vgaarb
changes") amended this driver's ->probe hook to lock decoding of normal
(non-legacy) I/O space accesses to the integrated GPU on dual-GPU
MacBook Pros. The lock stays in place until the driver is unbound.
The change was made to work around an issue with the out-of-tree nvidia
graphics driver (available at http://www.nvidia.com/object/unix.html).
It contains the following sequence in nvidia/nv.c:
#if defined(CONFIG_VGA_ARB) && !defined(NVCPU_PPC64LE)
#if defined(VGA_DEFAULT_DEVICE)
vga_tryget(VGA_DEFAULT_DEVICE, VGA_RSRC_LEGACY_MASK);
#endif
vga_set_legacy_decoding(dev, VGA_RSRC_NONE);
#endif
This code was reported to cause deadlocks with VFIO already in 2013:
https://devtalk.nvidia.com/default/topic/545560
I've reported the issue to Nvidia developers once more in 2017:
https://www.spinics.net/lists/dri-devel/msg138754.html
On the MacBookPro10,1, this code apparently breaks backlight control
(which is handled by apple-gmux via an I/O region starting at 0x700),
as reported by Petri Hodju:
https://bugzilla.kernel.org/show_bug.cgi?id=86121
I tried to replicate Petri's observations on my MacBook9,1, which uses
the same Intel Ivy Bridge + Nvidia GeForce GT 650M architecture, to no
avail. On my machine apple-gmux' I/O region remains accessible even
with the nvidia driver loaded and commit 4eebd5a4e7 reverted.
Petri reported that apple-gmux becomes accessible again after a
suspend/resume cycle because the BIOS changed the VGA routing on the
root port to the Nvidia GPU. Perhaps this is a BIOS issue after all
that can be fixed with an update?
In any case, the change made by commit 4eebd5a4e7 has turned out to
cause two new issues:
* Wilfried Klaebe reports a deadlock when launching Xorg because it
opens /dev/vga_arbiter and calls vga_get(), but apple-gmux is holding
a lock on I/O space indefinitely. It looks like apple-gmux' current
behavior is an abuse of the vgaarb API as locks are not meant to be
held for longer periods:
https://bugzilla.kernel.org/show_bug.cgi?id=88861#c11https://bugzilla.kernel.org/attachment.cgi?id=217541
* On dual GPU MacBook Pros introduced since 2013, the integrated GPU is
powergated on boot und thus becomes invisible to Linux unless a custom
EFI protocol is used to leave it powered on. (A patch exists but is
not in mainline yet due to several negative side effects.) On these
machines, locking I/O to the integrated GPU (as done by 4eebd5a4e7)
fails and backlight control is therefore broken:
https://bugzilla.kernel.org/show_bug.cgi?id=105051
So let's revert commit 4eebd5a4e7 please. Users experiencing the
issue with the proprietary nvidia driver can comment out the above-
quoted problematic code as a workaround (or try updating the BIOS).

Pull xfs updates from Darrick Wong:
"This merge cycle, we're again some substantive changes to XFS.
Metadata verifiers have been restructured to provide more detail about
which part of a metadata structure failed checks, and we've enhanced
the new online fsck feature to cross-reference extent allocation
information with the other metadata structures. With this pull, the
metadata verification part of online fsck is more or less finished,
though the feature is still experimental and still disabled by
default.
We're also preparing to remove the EXPERIMENTAL tag from a couple of
features this cycle. This week we're committing a bunch of space
accounting fixes for reflink and removing the EXPERIMENTAL tag from
reflink; I anticipate that we'll be ready to do the same for the
reverse mapping feature next week. (I don't have any pending fixes for
rmap; however I wish to remove the tags one at a time.)
This giant pile of patches has been run through a full xfstests run
over the weekend and through a quick xfstests run against this
morning's master, with no major failures reported. Let me know if
there's any merge problems -- git merge reported that one of our
patches touched the same function as the i_version series, but it
resolved things cleanly.

I was investigating an issue with seabios >= 1.10 which stopped working
for nested KVM on Hyper-V. The problem appears to be in
handle_ept_violation() function: when we do fast mmio we need to skip
the instruction so we do kvm_skip_emulated_instruction(). This, however,
depends on VM_EXIT_INSTRUCTION_LEN field being set correctly in VMCS.
However, this is not the case.
Intel's manual doesn't mandate VM_EXIT_INSTRUCTION_LEN to be set when
EPT MISCONFIG occurs. While on real hardware it was observed to be set,
some hypervisors follow the spec and don't set it; we end up advancing
IP with some random value.
I checked with Microsoft and they confirmed they don't fill
VM_EXIT_INSTRUCTION_LEN on EPT MISCONFIG.
Fix the issue by doing instruction skip through emulator when running
nested.

For EPT-violations that are triggered by a read, the pages are also mapped with
write permissions (if their memory region is also writable). That would avoid
getting yet another fault on the same page when a write occurs.
This optimization only happens when you have a "struct page" backing the memory
region. So also enable it for memory regions that do not have a "struct page".

As Linus points out:
The inode_cmp_iversion{+raw}() functions are pure and utter crap.
Why?
You say that they return 0/negative/positive, but they do so in a
completely broken manner. They return that ternary value as the
sequence number difference in a 's64', which means that if you
actually care about that ternary value, and do the *sane* thing that
the kernel-doc of the function implies is the right thing, you would
do
int cmp = inode_cmp_iversion(inode, old);
if (cmp < 0 ...
and as a result you get code that looks sane, but that doesn't
actually *WORK* right.
Since none of the callers actually care about the ternary value here,
convert the inode_cmp_iversion{+raw} functions to just return a boolean
value (false for matching, true for non-matching).
This matches the existing use of these functions just fine, and makes it
simple to convert them to return a ternary value in the future if we
grow callers that need it.
With this change we can also reimplement inode_cmp_iversion in a simpler
way using inode_peek_iversion.

This patch clears a single bit. The bit is 0 by default but expected
not to be set. Explicitly clearing the bit in this patch is intended
to indicate some thinking has occurred, and that we want this bit
cleared and we are not just excepting the default value.
We also stop setting GFX_RUN_LIST_ENABLE, which is correct since that
bit is gone.
