then the filtering function can use a scalar as input instead of a

In this case we can directly re-use filter_pred_cpu(), we just need to

The tracing_cpumask lets us specify which CPUs are traced in a buffer
instance, but doesn't let us do this on a per-event basis (unless one
creates an instance per event).
A previous commit added filtering scalar fields by a user-given cpumask,
make this work with the CPU common field as well.
This enables doing things like
$ trace-cmd record -e 'sched_switch' -f 'CPU & CPUS{12-52}' \
-e 'sched_wakeup' -f 'target_cpu & CPUS{12-52}'

Several events use a scalar field to denote a CPU:
o sched_wakeup.target_cpu
o sched_migrate_task.orig_cpu,dest_cpu
o sched_move_numa.src_cpu,dst_cpu
o ipi_send_cpu.cpu
o ...
Filtering these currently requires using arithmetic comparison functions,
which can be tedious when dealing with interleaved SMT or NUMA CPU ids.
Allow these to be filtered by a user-provided cpumask, which enables e.g.:
$ trace-cmd record -e 'sched_wakeup' -f 'target_cpu & CPUS{2,4,6,8-32}'

The recently introduced ipi_send_cpumask trace event contains a cpumask
field, but it currently cannot be used in filter expressions.
Make event filtering aware of cpumask fields, and allow these to be
filtered by a user-provided cpumask.
The user-provided cpumask is to be given in cpulist format and wrapped as:
"CPUS{$cpulist}". The use of curly braces instead of parentheses is to
prevent predicate_parse() from parsing the contents of CPUS{...} as a
full-fledged predicate subexpression.
This enables e.g.:
$ trace-cmd record -e 'ipi_send_cpumask' -f 'cpumask & CPUS{2,4,6,8-32}'

Every predicate allocation includes a MAX_FILTER_STR_VAL (256) char array
in the regex field, even if the predicate function does not use the field.
A later commit will introduce a dynamically allocated cpumask to struct
filter_pred, which will require a dedicated freeing function. Bite the
bullet and make filter_pred.regex dynamically allocated.
While at it, reorder the fields of filter_pred to fill in the byte
holes. The struct now fits on a single cacheline.
No change in behaviour intended.

During domain reset process vmd_domain_reset() clears PCI
configuration space of VMD root ports. But certain platform
has observed following errors and failed to boot.

The root cause is that memset_io() clears prefetchable memory base/limit
registers and prefetchable base/limit 32 bits registers sequentially.
This seems to be enabling prefetchable memory if the device disabled
prefetchable memory originally.
Here is an example (before memset_io()):
PCI configuration space for 10000:00:00.0:
86 80 30 20 06 00 10 00 04 00 04 06 00 00 01 00
00 00 00 00 00 00 00 00 00 01 01 00 00 00 00 20
00 00 00 00 01 00 01 00 ff ff ff ff 75 05 00 00
...
So, prefetchable memory is ffffffff00000000-575000fffff, which is
disabled. When memset_io() clears prefetchable base 32 bits register,
the prefetchable memory becomes 0000000000000000-575000fffff, which is
enabled and incorrect.
Here is the quote from section 7.5.1.3.9 of PCI Express Base 6.0 spec:
The Prefetchable Memory Limit register must be programmed to a smaller
value than the Prefetchable Memory Base register if there is no
prefetchable memory on the secondary side of the bridge.
This is believed to be the reason for the failure and in addition the
sequence of operation in vmd_domain_reset() is not following the PCIe
specs.
Disable the bridge window by executing a sequence of operations
borrowed from pci_disable_bridge_window() and pci_setup_bridge_io(),
that comply with the PCI specifications.

It is particularly important for the userns mount case (when a sensible
nr_inodes maximum may not be enforced) that tmpfs user xattrs be subject
to memory cgroup limiting. Leave temporary buffer allocations as is,
but change the persistent simple xattr allocations from GFP_KERNEL to
GFP_KERNEL_ACCOUNT. This limits kernfs's cgroupfs too, but that's good.
(I had intended to send this change earlier, but had been confused by
shmem_alloc_inode() using GFP_KERNEL, and thought a discussion would be
needed to change that too: no, I was forgetting the SLAB_ACCOUNT on that
kmem_cache, which implicitly adds __GFP_ACCOUNT to all its allocations.)

__efi_call_virt() exists as an alternative for efi_call_virt() for the
sole reason that ResetSystem() returns void, and so we cannot use a call
to it in the RHS of an assignment.
Given that there is only a single user, let's drop the macro, and expand
it into the caller. That way, the remaining macro can be tightened
somewhat in terms of type safety too.
Note that the use of typeof() on the runtime service invocation does not
result in an actual call being made, but it does require a few pointer
types to be fixed up and converted into the proper function pointer
prototypes.

lscpu parses /proc/cpuinfo and now believes it found different CPU
types since every CPU is listed with an unique identifier (PA
pathname).
Fix this problem by simply dropping the PA pathname when listing the
