Tasklets have long been deprecated as being too heavy on the system
by running in irq context - and this is not a performance critical
path. If a higher priority process wants to run, it must wait for
the tasklet to finish before doing so. A more suitable equivalent
is to converted to threaded irq instead and deal with the signaled
pipes in task context.

According to pvpanic spec:
https://git.qemu.org/?p=qemu.git;a=blob_plain;f=docs/specs/pvpanic.txt
The guest should determine pvpanic capability by RDPT, so initialize
capability during device probing. There is no need to register panic
notifier callback function if no events supported.
Before sending event to host side, check capability firstly.
Suggested by Greg KH, use sysfs to expose capability to user space,
also add new sysfs attribute in document.

Intel Moorestown and Medfield are quite old Intel Atom based
32-bit platforms, which were in limited use in some Android phones,
tablets and consumer electronics more than eight years ago.
There are no bugs or problems ever reported outside from Intel
for breaking any of that platforms for years. It seems no real
users exists who run more or less fresh kernel on it. The commit
05f4434bc1 ("ASoC: Intel: remove mfld_machine") also in align
with this theory.
Due to above and to reduce a burden of supporting outdated drivers
we remove the support of outdated platforms completely.

We do not actually need speakup_tty and spk_ttyio_synth global
variables, the synth can store the pointer to the tty, and the tty
ldisc_data can store the pointer to the synth.
Along the way, we can clench the initialization of the synth and the
creation of the tty, so that tty is never NULL. Even if the device
disappears (e.g. USB unplug), the tty structure will still be there,
and we automatically stop speakup in the spk_ttyio_out error handler
but keep tty until the user cleans things up.
As a result, this simplifies locking a lot.

When create the VMCI queue pair tracking data structures on the host
side, the IOCTL for creating the VMCI queue pair didn't validate
the queue pair size parameters. This change adds checks for this.
This avoids a memory allocation issue in qp_host_alloc_queue, as
reported by nslusarek@gmx.net. The check in qp_host_alloc_queue
has also been updated to enforce the maximum queue pair size
as defined by VMCI_MAX_GUEST_QP_MEMORY.
The fix has been verified using sample code supplied by
nslusarek@gmx.net.

Here are some small driver core fixes for 5.11-rc5 that resolve some
reported problems:
- revert of a -rc1 patch that was causing problems with some
machines
- device link device name collision problem fix (busses only
have to name devices unique to their bus, not unique to all
busses)
- kernfs splice bugfixes to resolve firmware loading problems
for Qualcomm systems.
- other tiny driver core fixes for minor issues reported.
All of these have been in linux-next with no reported problems.

The K: entry should ensure that Nick and I always get CC'd on patches that
touch these files but it is better to be explicit rather than implicit.

The process_sysctl_arg() does not check whether val is empty before
invoking strlen(val). If the command line parameter () is incorrectly
configured and val is empty, oops is triggered.
For example:
"hung_task_panic=1" is incorrectly written as "hung_task_panic", oops is
triggered. The call stack is as follows:
Kernel command line: .... hung_task_panic
......
Call trace:
__pi_strlen+0x10/0x98
parse_args+0x278/0x344
do_sysctl_args+0x8c/0xfc
kernel_init+0x5c/0xf4
ret_from_fork+0x10/0x30
To fix it, check whether "val" is empty when "phram" is a sysctl field.
Error codes are returned in the failure branch, and error logs are
generated by parse_args().

The original PowerPC highmem mapping function used __set_pte_at() to
denote that the mapping is per CPU. This got lost with the conversion
to the generic implementation.
Override the default map function.

set_pte_at() on MIPS invokes update_cache() which might recurse into
kmap_local().
Use set_pte() like the original MIPS highmem implementation did.

The generic kmap_local() map function uses set_pte_at(), but MIPS requires
set_pte() and PowerPC wants __set_pte_at().
Provide arch_kmap_local_set_pte() and default it to set_pte_at().
