that unwinding works properly.
- Fix stack unwinder test case to avoid rare interrupt stack corruption.
- Simplify udelay() and just let it busy loop instead of implementing a
complex logic.
- arch_cpu_idle() cleanup.

- Increase default size of vmalloc area to 512GB and otherwise let it increase

- Add support for the hugetlb_cma command line option to allocate
gigantic hugepages using CMA
- Add arch_get_random_long() support.
- Add ap bus userspace notifications.
- Increase default size of vmalloc area to 512GB and otherwise let it
increase dynamically by the size of physical memory. This should fix
all occurrences where the vmalloc area was not large enough.

When qeth_qdio_handle_aob() frees dangling allocations in the notified
TX buffer, there are rare tear-down cases where
qeth_drain_output_queue() would later call qeth_clear_output_buffer()
for the same buffer - and thus end up walking the buffer a second time
to check for dangling kmem_cache allocations.
Luckily current code previously scrubs such a buffer, so
qeth_clear_output_buffer() would find buf->buffer->element[i].addr as
NULL and not do anything. But this is fragile, and we can easily improve
it by consistently clearing the ->is_header flag after freeing the
allocation.

For TX buffers that require an additional async notification via QAOB, the
TX completion code can now manage all the necessary processing if the
notification has already occurred (or is occurring concurrently).
In such cases we can avoid replacing the metadata that is associated
with the buffer's slot on the ring, and just keep using the current one.
As qeth_clear_output_buffer() will also handle any kmem cache-allocated
memory that was mapped into the TX buffer, qeth_qdio_handle_aob()
doesn't need to worry about it.
While at it, also remove the unneeded forward declaration for
qeth_init_qdio_out_buf().

All qeth devices have a minimum set of sysfs attributes, and non-OSN
devices share a group of additional attributes. Depending on whether
the device is forced to use a specific discipline, the device_type then
specifies further attributes.
Shift the common attributes into dev->groups, so that the device_type
only contains the discipline-specific attributes. This avoids exposing
the common attributes to the disciplines, and nicely cleans up our
sysfs code.
While replacing the qeth_l*_*_device_attributes() helpers, switch from
sysfs_*_groups() to the more generic device_*_groups().

When qeth_iqd_tx_complete() detects that a TX buffer requires additional
async completion via QAOB, it might fail to replace the queue entry's
metadata (and ends up triggering recovery).
Assume now that the device gets torn down, overruling the recovery.
If the QAOB notification then arrives before the tear down has
sufficiently progressed, the buffer state is changed to
QETH_QDIO_BUF_HANDLED_DELAYED by qeth_qdio_handle_aob().
The tear down code calls qeth_drain_output_queue(), where
qeth_cleanup_handled_pending() will then attempt to replace such a
buffer _again_. If it succeeds this time, the buffer ends up dangling in
its replacement's ->next_pending list ... where it will never be freed,
since there's no further call to qeth_cleanup_handled_pending().
But the second attempt isn't actually needed, we can simply leave the
buffer on the queue and re-use it after a potential recovery has
completed. The qeth_clear_output_buffer() in qeth_drain_output_queue()
will ensure that it's in a clean state again.

The two expected notification sequences are
1. TX_NOTIFY_PENDING with a subsequent TX_NOTIFY_DELAYED_*, when
our TX completion code first observed the pending TX and the QAOB
then completes at a later time; or
2. TX_NOTIFY_OK, when qeth_qdio_handle_aob() picked up the QAOB
completion before our TX completion code even noticed that the TX
was pending.
But as qeth_iqd_tx_complete() and qeth_qdio_handle_aob() can run
concurrently, we may end up with a race that results in a sequence of
TX_NOTIFY_DELAYED_* followed by TX_NOTIFY_PENDING. Which would confuse
the af_iucv code in its tracking of pending transmits.
Rework the notification code, so that qeth_qdio_handle_aob() defers its
notification if the TX completion code is still active.

Remove workaround that supported early hardware implementations
of PNSO OC3. Rely on the 'enarf' feature bit instead.

Currently we have to consider too many different values which
in the end only affect identity mapping size. These are:
1. max_physmem_end - end of physical memory online or standby.
Always <= end of the last online memory block (get_mem_detect_end()).
2. CONFIG_MAX_PHYSMEM_BITS - the maximum size of physical memory the
kernel is able to support.
3. "mem=" kernel command line option which limits physical memory usage.
4. OLDMEM_BASE which is a kdump memory limit when the kernel is executed as
crash kernel.
5. "hsa" size which is a memory limit when the kernel is executed during
zfcp/nvme dump.
Through out kernel startup and run we juggle all those values at once
but that does not bring any amusement, only confusion and complexity.
Unify all those values to a single one we should really care, that is
our identity mapping size.

The link mode is a combination of port speed and port mode. But we
currently only consider the speed, and then typically select the
corresponding TP-based link mode. For 1G and 10G Fibre links this means
we display the wrong link modes.
Move the SPEED_* switch statements inside the PORT_* cases, and only
consider valid combinations where we can select the corresponding
link mode. Add the relevant link modes (1000baseX, 10000baseSR and
1000baseLR) that were introduced back with
commit 5711a98221 ("net: ethtool: add support for 1000BaseX and missing 10G link modes").
To differentiate between 10000baseSR and 10000baseLR, use the detailed
media_type information that QUERY OAT provides.

Improve the initial link info with data obtained from QUERY OAT.
Doing so _only_ at initialization time avoids
1. dealing with multi-part replies, and
2. sifting through all the data that may get returned at runtime.
This allows us to determine the correct port type for the 1000BT variant
of recent OSA adapter generations (where the .card_type field in
QUERY CARD INFO is no longer sufficient).

Remove the default case for PORT_* and SPEED_* in our ethtool code.
The only time these could be hit is if qeth_init_link_info() was unable
to determine the port type from an OSA adapter's link_type.
We already throw a message in this case, so reduce the noise and don't
report bad data (ie. it's much more likely that any future link_type
will represent a PORT_FIBRE link ...).

Hard-code the minimal link info at initialization time, after we
obtained the link_type. qeth_get_link_ksettings() can still override
this with more accurate data from QUERY CARD INFO later on.
Don't set arbitrary defaults for unknown OSA link types, they
certainly won't match any future type.
