The patch seems to apply without issue on RPI2 and appear to be helpful.
Stress2 tests have been running about 2x longer with the patch, though
crashes and silent hangs still occur. In some cases the debugger reports
zero values, but on occasion they are not zero, for example, at
www.zefox.net/~fbsd/rpi2/crashes/crash_10_11_15/console.

Apart from crashes under stress2 testing (usually in the syscall tests)
the Raspberry Pi seems vastly improved over a few months ago.
