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. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
