RISC-V SBI specification added a PMU extension that allows to configure
start/stop any pmu counter. The RISC-V perf can use most of the generic
perf features except interrupt overflow and event filtering based on
privilege mode which will be added in future.

It also allows to monitor a handful of firmware counters that can provide
insights into firmware activity during a performance analysis.

The old RISC-V perf implementation allowed counting of only
cycle/instruction counters using perf. Restore that feature by implementing
a simple platform driver under a separate config to provide backward
compatibility. Any existing software stack will continue to work as it is.
However, it provides an easy way out in future where we can remove the
legacy driver.

Implement a perf core library that can support all the essential perf
features in future. It can also accommodate any type of PMU implementation
in future. Currently, both SBI based perf driver and legacy driver
implemented uses the library. Most of the common perf functionalities
are kept in this core library wile PMU specific driver can implement PMU
specific features. For example, the SBI specific functionality will be
implemented in the SBI specific driver.

The current perf implementation in RISC-V is not very useful as it can not
count any events other than cycle/instructions. Moreover, perf record
can not be used or the events can not be started or stopped.

Remove the implementation now for a better platform driver in future
that will implement most of the missing functionality.

Current hart ISA ("riscv,isa") parser don't correctly parse:

1. Multi-letter extensions
2. Version numbers

All ISA extensions ratified recently has multi-letter extensions
(except 'H'). The current "riscv,isa" parser that is easily confused
by multi-letter extensions and "p" in version numbers can be a huge
problem for adding new extensions through the device tree.

Leaving it would create incompatible hacks and would make "riscv,isa"
value unreliable.

This commit implements minimal parser for "riscv,isa" strings.  With this,
we can safely ignore multi-letter extensions and version numbers.

 "Fix s390 breakage from sorting mcount tables.

  The latest merge of the tracing tree sorts the mcount table at build

  replaces the sorted table back to the original unsorted one. As the
  ftrace algorithm depends on it being sorted, bad things happen when it
  is not, and s390 experienced those bad things.

  Add a new config to tell the boot if the mcount table is sorted or
  not, and allow s390 to opt out of it"

  ftrace: Fix assuming build time sort works for s390

To speed up the boot process, as mcount_loc needs to be sorted for ftrace
to work properly, sorting it at build time is more efficient than boot up
and can save milliseconds of time. Unfortunately, this change broke s390
as it will modify the mcount_loc location after the sorting takes place
and will put back the unsorted locations. Since the sorting is skipped at
boot up if it is believed that it was sorted at run time, ftrace can crash
as its algorithms are dependent on the list being sorted.

Add a new config BUILDTIME_MCOUNT_SORT that is set when
BUILDTIME_TABLE_SORT but not if S390 is set. Use this config to determine
if sorting should take place at boot up.

A previous patch preventing "attr->sample_period" values from being
overridden in pfm events changed a related behaviour in arm-spe.

Before said patch:

  perf record -c 10000 -e arm_spe_0// -- sleep 1

Would yield an SPE event with period=10000. After the patch, the period
in "-c 10000" was being ignored because the arm-spe code initializes
sample_period to a non-zero value.

This patch restores the previous behaviour for non-libpfm4 events.

When CONFIG_MODULE_SIG_KEY is PKCS#11 URL (pkcs11:*), signing_key.x509
fails to build:

  certs/Makefile:77: *** target pattern contains no '%'.  Stop.

Due to the typo, $(X509_DEP) contains a colon.

Fix it.

This reverts commit cd8c917a.

Commit 129ab0d2 ("kbuild: do not quote string values in
include/config/auto.conf") provided the final solution.

Now reverting the temporary workaround.

As linux/nfc.h userspace compilation was finally fixed by commits
79b69a83 ("nfc: uapi: use kernel size_t to fix user-space builds")
and 7175f02c ("uapi: fix linux/nfc.h userspace compilation errors"),
there is no need to keep the compile-test exception for it in
usr/include/Makefile.

Pull more fscache updates from David Howells:
 "A set of fixes and minor updates for the fscache rewrite:

   - Fix mishandling of volume collisions (the wait condition is
     inverted and so it was only waiting if the volume collision was
     already resolved).

   - Fix miscalculation of whether there's space available in
     cachefiles.

   - Make sure a default cache name is set on a cache if the user hasn't
     set one by the time they bind the cache.

   - Adjust the way the backing inode is presented in tracepoints, add a
     tracepoint for mkdir and trace directory lookup.

   - Add a tracepoint for failure to set the active file mark.

   - Add an explanation of the checks made on the backing filesystem.

   - Check that the backing filesystem supports tmpfile.

   - Document how the page-release cancellation of the read-skip
     optimisation works.

  And I've included a change for netfslib:

   - Make ops->init_rreq() optional"
