x86/pv: Flush TLB in response to paging structure changes
With MMU_UPDATE, a PV guest can make changes to higher level pagetables. This
is safe from Xen's point of view (as the update only affects guest mappings),
and the guest is required to flush (if necessary) after making updates.
However, Xen's use of linear pagetables (UPDATE_VA_MAPPING, GNTTABOP_map,
writeable pagetables, etc.) is an implementation detail outside of the
API/ABI.
Changes in the paging structure require invalidations in the linear pagetable
range for subsequent accesses into the linear pagetables to access non-stale
mappings. Xen must provide suitable flushing to prevent intermixed guest
actions from accidentally accessing/modifying the wrong pagetable.
For all L2 and higher modifications, flush the TLB. PV guests cannot create
L2 or higher entries with the Global bit set, so no mappings established in
the linear range can be global. (This could in principle be an order 39 flush
starting at LINEAR_PT_VIRT_START, but no such mechanism exists in practice.)
Express the necessary flushes as a set of booleans which accumulate across the
operation. Comment the flushing logic extensively.
This is XSA-286.

x86/pv: Drop FLUSH_TLB_GLOBAL in do_mmu_update() for XPTI
c/s 9d1d31ad9498 "x86: slightly reduce Meltdown band-aid overhead" removed the
use of Global TLB flushes on the Xen entry path, but added a FLUSH_TLB_GLOBAL
to the L4 path in do_mmu_update().
However, this was unnecessary.
It is the guests responsibility to perform appropriate TLB flushing if the L4
modification altered an established mapping in a flush-relevant way. In this
case, an MMUEXT_OP hypercall will follow. The case which Xen needs to cover
is when new mappings are created, and the resync on the exit-to-guest path
covers this correctly.
There is a corner case with multiple vCPUs in hypercalls at the same time,
which 9d1d31ad9498 changed, and this patch changes back to its original XPTI
behaviour.
Architecturally, established TLB entries can continue to be used until the
broadcast flush has completed. Therefore, even with concurrent hypercalls,
the guest cannot depend on older mappings not being used until an MMUEXT_OP
hypercall completes. Xen's implementation of guest-initiated flushes will
take correct effect on top of an in-progress hypercall, picking up new mapping
setting before the other vCPU's MMUEXT_OP completes.
Note: The correctness of this change is not impacted by whether XPTI uses
global mappings or not. Correctness there depends on the behaviour of Xen on
the entry/exit paths when switching two/from the XPTI "shadow" pagetables.
This is (not really) XSA-286 (but necessary to simplify the logic).
