In Changeset 2021 there is the following commit message:
add ''system.multicall'' support to XML-RPC. boxcarred methods must

do_* declarations (was: Re: [Xen-ia64-devel] [PATCH] added multicall)
...o declare them in an
header file rather than locally. The question is in which header file.
Thank you for any suggestion.
The do_* functions are at least:
extern long do_ni_hypercall(void);
extern long do_dom0_op(dom0_op_t *u_dom0_op);
extern long do_memory_op(int cmd, void *arg);
extern long do_multicall(multicall_entry_t *call_list, unsigned int nr_calls);
extern long do_event_channel_op(evtchn_op_t *uop);

extern long do_console_io(int cmd, int count, char *buffer);

paravirt & xen & SMP
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() ...
Next question while looking at xen_load_gdt(): why does it use
multicalls in the first place? Seems that function puts onl...

Multicall
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.

[PATCH 0 of 4] mm+paravirt+xen: add pte read-modify-write abstraction
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);
