The code to handle writes to /proc/ppc64/lparcfg incorrectly
assumes that the return code from the helper routines to update
processor or memory entitlement return a hcall return value. It
then assumes any non-hcall return value is bad and sets the return
code for the write to be -EIO.
The update_[mp]pp routines can return values other than a hcall
return value. This patch removes the automatic setting of any
return code that is not an hcall return value from these routines
to -EIO.
NOTE: This patch applies on top of the CMO patches and my previous
patch for lparcfg.c.
