Hi all, I have a question concerning ActionWebService XMLRPC servers: Is it possible to send multicall requests to the Web service? I tried to use multicall and get the error message: no such method ''system.multicall'' on API [MyAPI] In Changeset 2021 there is the following commit message: add ''system.multicall'' support to XML-RPC. boxcarred methods must still...

Hi, Anyone has this working? Looks like there is a chicken-and-egg issue with pda setup: * xen_load_gdt() uses multicalls, thus depends on cpu-specific variables (per-cpu mc buffer) which in turn requires pda being setup already. * pda setup can't be done before xen_load_gdt() ...

This is my question: it is possible to call from one phone many others phones in the same time, like an "active" MeetMe function? I.e.: I make a call with a specified number. Asterisk lets ring many telephones together (like a group call). Then anyone that answer can hear and speak like MeetMe. Thanks for any answer. Alex

Hi all, This little series adds a new transaction-like abstraction for doing RMW updates to a pte, hooks it into paravirt_ops, and then makes use of it in Xen. The basic problem is that mprotect is very slow under Xen (up to 50x slower than native), primarily because of the ptent = ptep_get_and_clear(mm, addr, pte); ptent = pte_modify(ptent, newprot); /* ... */ set_pte_at(mm, addr, pte,
