b15e402fc8 trace-events: Fix attribution of trace points to source
Some trace points are attributed to the wrong source file.  Happens
when we neglect to update trace-events for code motion, or add events
in the wrong place, or misspell the file name.

Clean up with help of scripts/cleanup-trace-events.pl.  Funnies
requiring manual post-processing:

* accel/tcg/cputlb.c trace points are in trace-events.

* block.c and blockdev.c trace points are in block/trace-events.

* hw/block/nvme.c uses the preprocessor to hide its trace point use
  from cleanup-trace-events.pl.

* hw/tpm/tpm_spapr.c uses pseudo trace point tpm_spapr_show_buffer to
  guard debug code.

* include/hw/xen/xen_common.h trace points are in hw/xen/trace-events.

* linux-user/trace-events abbreviates a tedious list of filenames to
  */signal.c.

* net/colo-compare and net/filter-rewriter.c use pseudo trace points
  colo_compare_miscompare and colo_filter_rewriter_debug to guard
  debug code.

b636db306e hw/char/cadence_uart: add clock support
Switch the cadence uart to multi-phase reset and add the
reference clock input.

The input clock frequency is added to the migration structure.

The reference clock controls the baudrate generation. If it disabled,
any input characters and events are ignored.

If this clock remains unconnected, the uart behaves as before
(it default to a 50MHz ref clock).

3c77412b4a hw/char/exynos4210_uart: Add receive DMA support
To support receive DMA, we need to inform the DMA controller if receive data
is available. Otherwise the DMA controller keeps requesting data, causing
receive errors.

Implement this using an interrupt line. The instantiating code then needs
to connect the interrupt with the matching DMA controller GPIO pin.

when we neglect to update trace-events for code motion, or add events

Clean up with help of cleanup-trace-events.pl.  Same funnies as in the

500016e5db trace-events: Shorten file names in comments
We spell out sub/dir/ in sub/dir/trace-events' comments pointing to
source files.  That's because when trace-events got split up, the
comments were moved verbatim.

Delete the sub/dir/ part from these comments.  Gets rid of several
misspellings.

8908eb1a4a trace-events: fix code style: print 0x before hex numbers
The only exception are groups of numers separated by symbols
'.', ' ', ':', '/', like 'ab.09.7d'.

This patch is made by the following:

> find . -name trace-events | xargs python script.py

where script.py is the following python script:
=========================
 #!/usr/bin/env python

import sys
import re
import fileinput

rhex = '%[-+ *.0-9]*(?:[hljztL]|ll|hh)?(?:x|X|"\s*PRI[xX][^"]*"?)'
rgroup = re.compile('((?:' + rhex + '[.:/ ])+' + rhex + ')')
rbad = re.compile('(?<!0x)' + rhex)

files = sys.argv[1:]

for fname in files:
    for line in fileinput.input(fname, inplace=True):
        arr = re.split(rgroup, line)
        for i in range(0, len(arr), 2):
            arr[i] = re.sub(rbad, '0x\g<0>', arr[i])

        sys.stdout.write(''.join(arr))
