i_version mount option is getting lost on remount. This is because the
'i_version' mount option differs from the util-linux mount option
'iversion', but it has exactly the same functionality. We have to
specifically notify the vfs that this is what we want by setting
appropriate flag in fc->sb_flags. Fix it and as a result we can remove
*flags argument from __ext4_remount(); do the same for
__ext4_fill_super().

In addition set out to deprecate ext4 specific 'i_version' mount option
in favor or 'iversion' by kernel version 5.20.

The lazytime and nolazytime mount options were added temporarily back in
2015 with commit a26f4992 ("ext4: add optimization for the lazytime

lazytime support to get widely used. Remove the mount options.

Switching to the new mount api introduced inconsistency in how the
journalling mode mount option (data=) is handled during a remount.

Ext4 always prevented changing the journalling mode during the remount,
however the new code always fails the remount when the journalling mode
is specified, even if it remains unchanged. Fix it.

Add the necessary functions for the fs_context_operations. Convert and
rename ext4_remount() and ext4_fill_super() to ext4_get_tree() and
ext4_reconfigure() respectively and switch the ext4 to use the new api.

One user facing change is the fact that we no longer have access to the
entire string of mount options provided by mount(2) since the mount api
does not store it anywhere. As a result we can't print the options to
the log as we did in the past after the successful mount.

The new mount api separates option parsing and super block setup into
two distinct steps and so we need to separate the options parsing out of
the ext4_fill_super() and ext4_remount().

In order to achieve this we have to create new ext4_fill_super() and
ext4_remount() functions which will serve its purpose only until we
actually do convert to the new api (as such they are only temporary for
this patch series) and move the option parsing out of the old function
which will now be renamed to __ext4_fill_super() and __ext4_remount().

There is a small complication in the fact that while the mount option
parsing is going to happen before we get to __ext4_fill_super(), the
mount options stored in the super block itself needs to be applied
first, before the user specified mount options.

So with this patch we're going through the following sequence:

- parse user provided options (including sb block)
- initialize sbi and store s_sb_block if provided
- in __ext4_fill_super()
	- read the super block
	- parse and apply options specified in s_mount_opts
	- check and apply user provided options stored in ctx
	- continue with the regular ext4_fill_super operation

It's not exactly the most elegant solution, but if we still want to
support s_mount_opts we have to do it in this order.

Currently, an SEV-ES guest is terminated if the validation of the VMGEXIT
exit code or exit parameters fails.

The VMGEXIT instruction can be issued from userspace, even though
userspace (likely) can't update the GHCB. To prevent userspace from being
able to kill the guest, return an error through the GHCB when validation
fails rather than terminating the guest. For cases where the GHCB can't be
updated (e.g. the GHCB can't be mapped, etc.), just return back to the
guest.

The new error codes are documented in the lasest update to the GHCB
specification.

In commit c8c37359 ("parisc: Enhance detection of synchronous cr16

While booting up the kernel on two different C8000 machines, one with a
dual-core PA8800 and one with a dual-core PA8900 CPU, this turned out to be
wrong. The symptom was that I saw a jump in the internal clocks printed to the
syslog and strange overall behaviour.  On machines which have 4 cores (2
dual-cores) the problem isn't visible, because the current logic already marked
the cr16 clocksource unstable in this case.

This patch now marks the cr16 interval timers unstable if we have more than one
CPU in the system, and it fixes this issue.

Commit d81ae8aa ("sched/uclamp: Fix initialization of struct
uclamp_rq") introduced a bug where uclamp_max of the rq is not reset to
match the woken up task's uclamp_max when the rq is idle.

The code was relying on rq->uclamp_max initialized to zero, so on first
enqueue

	static inline void uclamp_rq_inc_id(struct rq *rq, struct task_struct *p,
					    enum uclamp_id clamp_id)
	{
		...

		if (uc_se->value > READ_ONCE(uc_rq->value))
			WRITE_ONCE(uc_rq->value, uc_se->value);
	}

was actually resetting it. But since commit d81ae8aa changed the
default to 1024, this no longer works. And since rq->uclamp_flags is
also initialized to 0, neither above code path nor uclamp_idle_reset()
update the rq->uclamp_max on first wake up from idle.

This is only visible from first wake up(s) until the first dequeue to
idle after enabling the static key. And it only matters if the
uclamp_max of this task is < 1024 since only then its uclamp_max will be
effectively ignored.

Fix it by properly initializing rq->uclamp_flags = UCLAMP_FLAG_IDLE to
ensure uclamp_idle_reset() is called which then will update the rq
uclamp_max value as expected.
