Stefano GarzarellaandThomas Huth d0fb9657a3 docs: fix references to docs/devel/tracing.rst
Commit e50caf4a5c ("tracing: convert documentation to rST")
converted docs/devel/tracing.txt to docs/devel/tracing.rst.

We still have several references to the old file, so let's fix them
with the following command:

  sed -i s/tracing.txt/tracing.rst/ $(git grep -l docs/devel/tracing.txt)

Markus ArmbrusterandStefan Hajnoczi 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.

Niek LinnenbankandPeter Maydell a9ad9e73a7 hw/arm/allwinner: add RTC device support
Allwinner System-on-Chips usually contain a Real Time Clock (RTC)
for non-volatile system date and time keeping. This commit adds a generic
Allwinner RTC device that supports the RTC devices found in Allwinner SoC
family sun4i (A10), sun7i (A20) and sun6i and newer (A31, H2+, H3, etc).
The following RTC functionality and features are implemented:

 * Year-Month-Day read/write
 * Hour-Minute-Second read/write
 * General Purpose storage

The following boards are extended with the RTC device:

 * Cubieboard (hw/arm/cubieboard.c)
 * Orange Pi PC (hw/arm/orangepi.c)

Anup PatelandPalmer Dabbelt 9a5b40b842 hw: rtc: Add Goldfish RTC device
This patch adds model for Google Goldfish virtual platform RTC device.

We will be adding Goldfish RTC device to the QEMU RISC-V virt machine
for providing real date-time to Guest Linux. The corresponding Linux
driver for Goldfish RTC device is already available in upstream Linux.

For now, VM migration support is available but untested for Goldfish RTC
device. It will be hardened in-future when we implement VM migration for
KVM RISC-V.
