The skip_sep() routine has the same implementation as skip_spaces(),
recently adopted from the kernel, sources, switch to it.

There were a few places where we still were using the libc version of
ctype.h, switch to the one in tools/lib/ctype.c that the rest of perf
uses.

We got the sane_ctype.h headers from git and kept using it so far, but
since that code originally came from the kernel sources to the git
sources, perhaps its better to just use the one in the kernel, so that
we can leverage tools/perf/check_headers.sh to be notified when our copy
gets out of sync, i.e. when fixes or goodies are added to the code we've
copied.
This will help with things like tools/lib/string.c where we want to have
more things in common with the kernel, such as strim(), skip_spaces(),
etc so as to go on removing the things that we have in tools/perf/util/
and instead using the code in the kernel, indirectly and removing things
like EXPORT_SYMBOL(), etc, getting notified when fixes and improvements
are made to the original code.
Hopefully this also should help with reducing the difference of code
hosted in tools/ to the one in the kernel proper.

It was just including a ../util.h that wasn't even there:
$ cat tools/perf/util/include/linux/../util.h
cat: tools/perf/util/include/linux/../util.h: No such file or directory
$
This would make kallsyms.h get util.h somehow and then files including
it would get util.h defined stuff, a mess, fix it.

Those are not in that file in the git repo, lets move it from there so
that we get that sane ctype code fully isolated to allow getting it in
sync either with the git sources or better with the kernel sources
(include/linux/ctype.h + lib/ctype.h), that way we can use
check_headers.h to get notified when changes are made in the original
code so that we can cherry-pick.

We can just use the 'field width' for the %s used to print the
alignment, this way we'll get the same result without requiring having a
variable with just lots of space chars.
No way to do that for the dots tho, we still need that variable filled
with dot chars.

ptwrite events
The format of synthesized events is determined by the attribute config.
For the formats for Intel PT power and ptwrite events, create tables and
populate them when the synth_data handler is called. If the tables
remain empty, drop them at the end.
The tables and views, including a combined power_events_view, will
display automatically from the tables menu of the exported
exported-sql-viewer.py script.
Note, currently only Atoms since Gemini Lake have support for ptwrite
and mwait, pwre, exstop and pwrx, but all Intel PT implementations
support cbr.

The core-to-bus ratio (CBR) provides the CPU frequency. With branches
enabled, the decoder was outputting CBR changes only when there was a
branch. That loses the correct time of the change if the trace is not in
context (e.g. not tracing kernel space). Change to output the CBR change
immediately.

way too many cpu caches..
[ perf record: Captured and wrote X MB perf.data (X samples) ]
perf report -C 1024
Error: failed to set cpu bitmap
Requested CPU 1024 too large. Consider raising MAX_NR_CPUS
Increasing MAX_NR_CPUS from 1024 to 2048 and redefining MAX_CACHES as
MAX_NR_CPUS * 4 returns normal functionality to perf:

Commit f08046cb3082 ("perf thread-stack: Represent jmps to the start of a
different symbol") had the side-effect of introducing more stack entries
before return from kernel space.
When user space is also traced, those entries are popped before entry to
user space, but when user space is not traced, they get stuck at the
bottom of the stack, making the stack grow progressively larger.
Fix by detecting a return-from-kernel branch type, and popping kernel
addresses from the stack then.
Note, the problem and fix affect the exported Call Graph / Tree but not
the callindent option used by "perf script --call-trace".
Example:
perf-with-kcore record example -e intel_pt//k -- ls
perf-with-kcore script example --itrace=bep -s ~/libexec/perf-core/scripts/python/export-to-sqlite.py example.db branches calls

The first arg to the perf-with-kcore needs to be the same for the
'record' and 'script' lines, otherwise we'll record the perf.data file
and kcore_dir/ files in one directory ('example') to then try to use it
from the 'bep' directory, fix the instructions above it so that both use
'example'.

Committer notes:
$ ls -la tools/perf/ui/../cache.h
ls: cannot access 'tools/perf/ui/../cache.h': No such file or directory
So it really should include ../../util/cache.h, or plain cache.h, since

are going to be a bit more difficult and the people on the spdx list
will be discussing them on a case-by-case basis now.

Files checked: 64545

Compared to the 5.1 kernel which was:
Files checked: 63848

Commit 332d079735f5 ("KVM: nVMX: KVM_SET_NESTED_STATE - Tear down old EVMCS
state before setting new state", 2019-05-02) broke evmcs_test because the
eVMCS setup must be performed even if there is no VMXON region defined,
as long as the eVMCS bit is set in the assist page.
While the simplest possible fix would be to add a check on
kvm_state->flags & KVM_STATE_NESTED_EVMCS in the initial "if" that
covers kvm_state->hdr.vmx.vmxon_pa == -1ull, that is quite ugly.
Instead, this patch moves checks earlier in the function and
conditionalizes them on kvm_state->hdr.vmx.vmxon_pa, so that
vmx_set_nested_state always goes through vmx_leave_nested
and nested_enable_evmcs.
