434929bf11 Make page_find() return 0 for too-large addresses (Eduardo Habkost)
On some cases, such as under KVM, tb_invalidate_phys_page_range()
may be called for large addresses, when qemu is configured to more than
4GB of RAM.

On these cases, qemu was crashing because it was using an index too
large for l1_map[], that supports only 32-bit addresses when compiling
without CONFIG_USER_ONLY.

0f459d16c3 Clean up MMIO TLB handling.
The IO index is now stored in its own field, instead of being wedged
into the vaddr field.  This eliminates the ROMD and watchpoint host
pointer weirdness.  The IO index space is expanded by 1 bit, and
several additional bits are made available in the TLB vaddr field.

7d03f82f81 Add support for the 'k' (kill) and 'D' (detach) packets (Jason Wessel).
Implement the 'k' gdbserial packet which kills the qemu instance via
the debugger stub.

Implement the 'D' detach packet for the gdb stub such that you can
disconnect gdb with the "detach" command.  This required implementing
a cpu_breakpoint_remove_all() and a cpu_watchpoint_remove_all()
function to cleanup all the breakpoints and watchpoints prior to
leaving the gdb stub else simulation can stop with no debugger
attached.

On a '?' packet remove all the breakpoints and watchpoints.  This is
considered more of a safety net in case you force killed gdb or it
crashed and you are reconnecting.  The identical behavior exists for
kgdb in the linux kernel.
