Tasklet irq_rx_tasklet is scheduled when hw is receiving frames. Function
_rtl92e_irq_rx_tasklet() is then called which calls then
_rtl92e_rx_normal(). In _rtl92e_rx_normal() all frames are processed by
rtllib_rx(). When ieee->iw_mode is IW_MODE_MESH the function returns
0. The calling function then calls: dev_kfree_skb_any() which clears
the skb. So the driver clears all packets received in this mode. Remove
dead code in mode IW_MODE_MESH.

Pull tracing fixes from Steven Rostedt:
- Fix to /sys/kernel/tracing/per_cpu/cpu*/stats read and entries.
If a resize shrinks the buffer it clears the read count to notify
readers that they need to reset. But the read count is also used for
accounting and this causes the numbers to be off. Instead, create a
separate variable to use to notify readers to reset.
- Fix the ref counts of the "soft disable" mode. The wrong value was
used for testing if soft disable mode should be enabled or disable,
but instead, just change the logic to do the enable and disable in
place when the SOFT_MODE is set or cleared.

Commit a2225d931f ("autofs: remove left-over autofs4 stubs")
promised the removal of the fs/autofs/Kconfig fragment for AUTOFS4_FS
within a couple of releases, but five years later this still has not
happened yet, and AUTOFS4_FS is still enabled in 63 defconfigs.
Get rid of it mechanically:
git grep -l CONFIG_AUTOFS4_FS -- '*defconfig' |
xargs sed -i 's/AUTOFS4_FS/AUTOFS_FS/'
Also just remove the AUTOFS4_FS config option stub. Anybody who hasn't
regenerated their config file in the last five years will need to just
get the new name right when they do.

Add coverage to x86's set_sregs_test to verify KVM rejects vendor-agnostic
illegal CR0 values, i.e. CR0 values whose legality doesn't depend on the
current VMX mode. KVM historically has neglected to reject bad CR0s from
userspace, i.e. would happily accept a completely bogus CR0 via
KVM_SET_SREGS{2}.
Punt VMX specific subtests to future work, as they would require quite a
bit more effort, and KVM gets coverage for CR0 checks in general through
other means, e.g. KVM-Unit-Tests.
