Refactor Hyper-V's range-based TLB flushing API to take a gfn+nr_pages
pair instead of a struct, and bury said struct in Hyper-V specific code.
Passing along two params generates much better code for the common case
where KVM is _not_ running on Hyper-V, as forwarding the flush on to
Hyper-V's hv_flush_remote_tlbs_range() from kvm_flush_remote_tlbs_range()
becomes a tail call.

Modules can (and usually do) have multiple alias tags, in order to
specify multiple possible device matches for autoloading. Allow this by
changing the alias ModuleInfo field to an Option<Vec<String>>.
Note: For normal device IDs this is autogenerated by modpost (which is
not properly integrated with Rust support yet), so it is useful to be
able to manually add device match aliases for now, and should still be
useful in the future for corner cases that modpost does not handle.
This pulls in the expect_group() helper from the rfl/rust branch
(with credit to authors).

This commit fixes a pair of bugs in which an improbable but very real
sequence of events can cause kfree_rcu() to be a bit too quick about
freeing the memory passed to it. It turns out that this pair of bugs
is about two years old, and so this is not a v6.3 regression. However:
(1) It just started showing up in the wild and (2) Its consequences are
dire, so its fix needs to go in sooner rather than later.
Testing is of course being upgraded, and the upgraded tests detect this
situation very quickly. But to the best of my knowledge right now, the
tests are not particularly urgent and will thus most likely show up in
the v6.5 merge window (the one after this coming one).
Kudos to Ziwei Dai and his group for tracking this one down the hard way!

memalign() is obsolete according to its manpage.
Replace memalign() with posix_memalign() and remove malloc.h include
that was there for memalign().
As a pointer is passed into posix_memalign(), initialize *p to NULL
to silence a warning about the function's return value being used as
uninitialized (which is not valid anyway because the error is properly
checked before p is returned).

resctrl_val() assumes ->setup() always returns either 0 to continue
tests or < 0 in case of the normal termination of tests after x runs.
The latter overlaps with normal error returns.

tests and return errors as negative values. Alter callers of ->setup()
to handle errors properly.

During umount(), if cp_error is set, f2fs_wait_on_all_pages() should
not stop waiting all F2FS_WB_CP_DATA pages to be writebacked, otherwise,
fsync_node_num can be non-zero after f2fs_wait_on_all_pages() causing

In this case, to avoid deadloop in f2fs_wait_on_all_pages(), it needs
to drop all dirty pages rather than redirtying them.
