available.

c331bdc777 record: Allow tracing of ISR disable/enable 
Directly use the CPU port API in boot_card() to allow tracing of the
higher level interrupt disable/enable routines, e.g.
_ISR_Local_disable() and _ISR_Local_enable().  Currently, there is no
configuration option to enable this.  Below is a patch.  It may be used
to investigate some nasty low level bugs in the system.

Update #3665.

a2684c2b8d record: Use BSS section instead of per-CPU data 
The .rtemsrwset section is used for the per-CPU data.  This section has
loadable content.  Place the ring buffers in the BSS section to avoid
large executable image sizes.

Not using the per-CPU data makes it possible to initialize the record
support earlier.

52c8ac7b69 record: Improve overflow handling 
In case of a ring buffer overflow, the rtems_record_drain() will push
the complete ring buffer content to the client.  While the items are
processed by the client, new items may overwrite some items being
processed.  The overwritten items can be detected in the following
iteration once the next tail/head information is pushed to the client.
