[Qemu-devel] [PATCH v3] Modifications to fix PowerPC on 64bit host, bug 1052857

[Samuel Seay]

Removed h2g() macro around the ka->_sa_handler due to the _sa_handler being a 
guest memory address
Changed the __put_user to put_user as it was attempting to put a value at the 
stack address but the new address is a guest memory address, __put_user is for 
host memory addresses.
Patch v2 -> v3, removed unneeded casting in the put_user call left over from 
__put_user
