[PATCH/RFC] mm: add and use batched version of __tlb_remove_table()

[Sam Ravnborg]

Hi Nikita,

How about adding the following to tlb.h:

#ifndef __tlb_remove_tables
static void __tlb_remove_tables(...)
{
	....
}
#endif


And then the few archs that want to override __tlb_remove_tables
needs to do a
#define __tlb_remove_tables __tlb_remove_tables
static void __tlb_remove_tables(...)
{
	...
}

In this way the archs that uses the default implementation needs not do
anything.
A few functions already uses this pattern in tlb.h - see for example tlb_start_vma
io.h is another file where you can see the same pattern.
