Upgrade Xen interface headers to Xen 4.2.1.

Browse Source 
Move FreeBSD from interface version 0x00030204 to 0x00030208.
Updates are required to our grant table implementation before we
can bump this further.

sys/xen/hvm.h:
	Replace the implementation of hvm_get_parameter(), formerly located
	in sys/xen/interface/hvm/params.h.  Linux has a similar file which
	primarily stores this function.

sys/xen/xenstore/xenstore.c:
	Include new xen/hvm.h header file to get hvm_get_parameter().

sys/amd64/include/xen/xen-os.h:
sys/i386/include/xen/xen-os.h:
	Correctly protect function definition and variables from being
	included into assembly files in xen-os.h

	Xen memory barriers are now prefixed with "xen_" to avoid conflicts
	with OS native primatives.  Define Xen memory barriers in terms of
	the native FreeBSD primatives.

* Event channels are the basic primitive provided by Xen for event
* notifications. An event is the Xen equivalent of a hardware
* interrupt. They essentially store one bit of information, the event
* of interest is signalled by transitioning this bit from 0 to 1.
*
* Notifications are received by a guest via an upcall from Xen,
* indicating when an event arrives (setting the bit). Further
* notifications are masked until the bit is cleared again (therefore,
* guests must check the value of the bit after re-enabling event
* delivery to ensure no missed notifications).
*
* Event notifications can be masked by setting a flag; this is
* equivalent to disabling interrupts and can be used to ensure
* atomicity of certain operations in the guest kernel.
*
* Event channels are represented by the evtchn_* fields in

* Xen's grant tables provide a generic mechanism to memory sharing

* device drivers for block and network IO.
*
* Each domain has its own grant table. This is a data structure that
* is shared with Xen; it allows the domain to tell Xen what kind of
* permissions other domains have on its pages. Entries in the grant
* table are identified by grant references. A grant reference is an
* integer, which indexes into the grant table. It acts as a
* capability which the grantee can use to perform operations on the
* granter’s memory.
*
* This capability-based system allows shared-memory communications
* between unprivileged domains. A grant reference also encapsulates
* the details of a shared page, removing the need for a domain to
* know the real machine address of a page it is sharing. This makes
* it possible to share memory correctly with domains running in
* fully virtualised memory.

* @section DESCRIPTION
*
* Originally borrowed from the Qubes OS Project, http://www.qubes-os.org,
* this code has been substantially rewritten to use the gntdev and gntalloc
* devices instead of raw MFNs and map_foreign_range.
*
* This is a library for inter-domain communication. A standard Xen ring
* buffer is used, with a datagram-based interface built on top. The grant
* reference and event channels are shared in XenStore under a user-specified
* path.
*
* The ring.h macros define an asymmetric interface to a shared data structure
* that assumes all rings reside in a single contiguous memory space. This is
* not suitable for vchan because the interface to the ring is symmetric except
* for the setup. Unlike the producer-consumer rings defined in ring.h, the
* size of the rings used in vchan are determined at execution time instead of
* compile time, so the macros in ring.h cannot be used to access the rings.

* MMU-UPDATE REQUESTS
*
* HYPERVISOR_mmu_update() accepts a list of (ptr, val) pairs.
* A foreigndom (FD) can be specified (or DOMID_SELF for none).
* Where the FD has some effect, it is described below.
* ptr[1:0] specifies the appropriate MMU_* command.
* ` enum neg_errnoval
* ` HYPERVISOR_mmu_update(const struct mmu_update reqs[],
* ` unsigned count, unsigned *done_out,
* ` unsigned foreigndom)
* `
* @reqs is an array of mmu_update_t structures ((ptr, val) pairs).
* @count is the length of the above array.
* @pdone is an output parameter indicating number of completed operations
* @foreigndom[15:0]: FD, the expected owner of data pages referenced in this
* hypercall invocation. Can be DOMID_SELF.
* @foreigndom[31:16]: PFD, the expected owner of pagetable pages referenced
* in this hypercall invocation. The value of this field
* (x) encodes the PFD as follows:
* x == 0 => PFD == DOMID_SELF
* x != 0 => PFD == x - 1
*
* Sub-commands: ptr[1:0] specifies the appropriate MMU_* command.
* -------------
* ptr[1:0] == MMU_NORMAL_PT_UPDATE:
* Updates an entry in a page table. If updating an L1 table, and the new
* table entry is valid/present, the mapped frame must belong to the FD, if
* an FD has been specified. If attempting to map an I/O page then the
* caller assumes the privilege of the FD.
* Updates an entry in a page table belonging to PFD. If updating an L1 table,
* and the new table entry is valid/present, the mapped frame must belong to
* FD. If attempting to map an I/O page then the caller assumes the privilege
* of the FD.
* FD == DOMID_IO: Permit /only/ I/O mappings, at the priv level of the caller.
* FD == DOMID_XEN: Map restricted areas of Xen's heap space.
* ptr[:2] -- Machine address of the page-table entry to modify.
* val -- Value to write.
*
* There also certain implicit requirements when using this hypercall. The
* pages that make up a pagetable must be mapped read-only in the guest.
* This prevents uncontrolled guest updates to the pagetable. Xen strictly
* enforces this, and will disallow any pagetable update which will end up
* mapping pagetable page RW, and will disallow using any writable page as a
* pagetable. In practice it means that when constructing a page table for a
* process, thread, etc, we MUST be very dilligient in following these rules:
* 1). Start with top-level page (PGD or in Xen language: L4). Fill out
* the entries.
* 2). Keep on going, filling out the upper (PUD or L3), and middle (PMD
* or L2).
* 3). Start filling out the PTE table (L1) with the PTE entries. Once
* done, make sure to set each of those entries to RO (so writeable bit
* is unset). Once that has been completed, set the PMD (L2) for this
* PTE table as RO.
* 4). When completed with all of the PMD (L2) entries, and all of them have
* been set to RO, make sure to set RO the PUD (L3). Do the same
* operation on PGD (L4) pagetable entries that have a PUD (L3) entry.
* 5). Now before you can use those pages (so setting the cr3), you MUST also
* pin them so that the hypervisor can verify the entries. This is done
* via the HYPERVISOR_mmuext_op(MMUEXT_PIN_L4_TABLE, guest physical frame
* number of the PGD (L4)). And this point the HYPERVISOR_mmuext_op(
* MMUEXT_NEW_BASEPTR, guest physical frame number of the PGD (L4)) can be
* issued.
* For 32-bit guests, the L4 is not used (as there is less pagetables), so
* instead use L3.
* At this point the pagetables can be modified using the MMU_NORMAL_PT_UPDATE
* hypercall. Also if so desired the OS can also try to write to the PTE
* and be trapped by the hypervisor (as the PTE entry is RO).
*
* To deallocate the pages, the operations are the reverse of the steps
* mentioned above. The argument is MMUEXT_UNPIN_TABLE for all levels and the
* pagetable MUST not be in use (meaning that the cr3 is not set to it).
*
* ptr[1:0] == MMU_MACHPHYS_UPDATE:
* Updates an entry in the machine->pseudo-physical mapping table.
@ -183,6 +245,72 @@ DEFINE_XEN_GUEST_HANDLE(xen_pfn_t);
* ptr[1:0] == MMU_PT_UPDATE_PRESERVE_AD:
* As MMU_NORMAL_PT_UPDATE above, but A/D bits currently in the PTE are ORed
* with those in @val.
*
* @val is usually the machine frame number along with some attributes.
* The attributes by default follow the architecture defined bits. Meaning that
* if this is a X86_64 machine and four page table layout is used, the layout
* of val is:
* - 63 if set means No execute (NX)
* - 46-13 the machine frame number
* - 12 available for guest
* - 11 available for guest
* - 10 available for guest
* - 9 available for guest
* - 8 global
* - 7 PAT (PSE is disabled, must use hypercall to make 4MB or 2MB pages)
* - 6 dirty
* - 5 accessed
* - 4 page cached disabled
* - 3 page write through
* - 2 userspace accessible
* - 1 writeable
* - 0 present
*
* The one bits that does not fit with the default layout is the PAGE_PSE
* also called PAGE_PAT). The MMUEXT_[UN]MARK_SUPER arguments to the
* HYPERVISOR_mmuext_op serve as mechanism to set a pagetable to be 4MB
* (or 2MB) instead of using the PAGE_PSE bit.
*
* The reason that the PAGE_PSE (bit 7) is not being utilized is due to Xen
* using it as the Page Attribute Table (PAT) bit - for details on it please
* refer to Intel SDM 10.12. The PAT allows to set the caching attributes of
* pages instead of using MTRRs.
*
* The PAT MSR is as follow (it is a 64-bit value, each entry is 8 bits):
* PAT4 PAT0
* +---+----+----+----+-----+----+----+
* WC | WC | WB | UC | UC- | WC | WB | <= Linux
* +---+----+----+----+-----+----+----+
* WC | WT | WB | UC | UC- | WT | WB | <= BIOS (default when machine boots)
* +---+----+----+----+-----+----+----+
* WC | WP | WC | UC | UC- | WT | WB | <= Xen
* +---+----+----+----+-----+----+----+
*
* The lookup of this index table translates to looking up
* Bit 7, Bit 4, and Bit 3 of val entry:
*
* PAT/PSE (bit 7) ... PCD (bit 4) .. PWT (bit 3).
*
* If all bits are off, then we are using PAT0. If bit 3 turned on,
* then we are using PAT1, if bit 3 and bit 4, then PAT2..
*
* As you can see, the Linux PAT1 translates to PAT4 under Xen. Which means
* that if a guest that follows Linux's PAT setup and would like to set Write
* Combined on pages it MUST use PAT4 entry. Meaning that Bit 7 (PAGE_PAT) is
* set. For example, under Linux it only uses PAT0, PAT1, and PAT2 for the
* caching as:
*
* WB = none (so PAT0)
* WC = PWT (bit 3 on)
* UC = PWT | PCD (bit 3 and 4 are on).
*
* To make it work with Xen, it needs to translate the WC bit as so:
*
* PWT (so bit 3 on) --> PAT (so bit 7 is on) and clear bit 3
*
* And to translate back it would:
*
* PAT (bit 7 on) --> PWT (bit 3 on) and clear bit 7.
