This delay is needed to fix resume from s2idle of the XHCI controller on
AMD Ryzen SoCs, where a 20ms delay is required (this will be quirked
in a followup patch), to avoid this failure:
At this point, the device has been set to D0 at the platform level,
so pci_update_current_state() reads pmcsr and updates dev->current_state
to D3hot. Now when we reach pci_raw_set_power_state() the D3 delay will
be applied.
However, the D3cold resume from s2idle path is somewhat different, and
we arrive at the same function without hitting pci_update_current_state()
along the way:
pci_pm_resume_noirq
-> pci_pm_default_resume_early
-> pci_power_up
-> pci_raw_set_power_state
As dev->current_state is D3cold, the D3 delay is skipped and the XHCI
controllers fail to be powered up.
Apply the D3 delay in the s2idle resume case too, in order to fix
USB functionality after resume.

cramfs: fix usage on non-MTD device
When both CONFIG_CRAMFS_MTD and CONFIG_CRAMFS_BLOCKDEV are enabled, if
we fail to mount on MTD, we don't try on block device.
Note: this relies upon cramfs_mtd_fill_super() leaving no side
effects on fc state in case of failure; in general, failing
get_tree_...() does *not* mean "fine to try again"; e.g. parsed
options might've been consumed by fill_super callback and freed
on failure.

Pull input fix from Dmitry Torokhov:
"Just a single revert as RMI mode should not have been enabled for this
model [yet?]"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
Revert "Input: synaptics - enable RMI mode for X1 Extreme 2nd Generation"
This reverts commit 68b9c5066e39af41d3448abfc887c77ce22dd64d.
Ugh, I really dropped the ball on this one :\. So as it turns out RMI4
works perfectly fine on the X1 Extreme Gen 2 except for one thing I
didn't notice because I usually use the trackpoint: clicking with the
touchpad. Somehow this is broken, in fact we don't even seem to indicate
BTN_LEFT as a valid event type for the RMI4 touchpad. And, I don't even
see any RMI4 events coming from the touchpad when I press down on it.
This only seems to work for PS/2 mode.
Since that means we have a regression, and PS/2 mode seems to work fine
for the time being - revert this for now. We'll have to do a more
thorough investigation on this.

By default s_maxbytes is set to MAX_NON_LFS, which limits the usable
file size to 2GB, enforced by the vfs.
Commit b9b1f8d5930a ("AFS: write support fixes") added support for the
64-bit fetch and store server operations, but did not change this value.
As a result, attempts to write past the 2G mark result in EFBIG errors:
$ dd if=/dev/zero of=foo bs=1M count=1 seek=2048
dd: error writing 'foo': File too large
Set s_maxbytes to MAX_LFS_FILESIZE.

afs: Fix possible assert with callbacks from yfs servers
Servers sending callback breaks to the YFS_CM_SERVICE service may
send up to YFSCBMAX (1024) fids in a single RPC. Anything over
AFSCBMAX (50) will cause the assert in afs_break_callbacks to trigger.
Remove the assert, as the count has already been checked against
the appropriate max values in afs_deliver_cb_callback and
afs_deliver_yfs_cb_callback.
