[Qemu-devel] [PATCH 0/2] fw_cfg: *prequel* to cleanup series

[Gabriel L. Somlo]

The fw_cfg cleanup series exposed a memory leak occurring on ppc and sparc
machine types.

This series adds a safe fw_cfg integer-type update function (1/2), and
modifies ppc and sparc callbacks to use it instead of the current leaky
method (2/2).

This should preferably go in *before* "fw_cfg: remove support for guest-side 
data writes", which would otherwise cause certain ppc and sparc command
lines to crash.

Once these are reviewed (also, see additional questions in 1/1), should I
re-spin the whole set, or keep these two as a separate, independent series?

Thanks,
  Gabriel
