fc377bcf617a48233a99a9fe0a26247c38b5cb76 translate-all: make less of tb_invalidate_phys_page_range depend on is_cpu_write_access
is_cpu_write_access is only set if tb_invalidate_phys_page_range is called
from tb_invalidate_phys_page_fast, and hence from notdirty_mem_write.
However:
- the code bitmap can be built directly in tb_invalidate_phys_page_fast
(unconditionally, since is_cpu_write_access would always be passed as 1);
- the virtual address is not needed to mark the page as "not containing
code" (dirty code bitmap = 1), so we can also remove that use of
is_cpu_write_access. For calls of tb_invalidate_phys_page_range
that do not come from notdirty_mem_write, the next call to
notdirty_mem_write will notice that the page does not contain code
anymore, and will fix up the TLB entry.
The parameter needs to remain in order to guard accesses to cpu->mem_io_pc.
