@ -66,10 +66,10 @@ trick is to ensure that any needed memory allocations are done before
entering atomic context, using:
int flex_array_prealloc(struct flex_array *array, unsigned int start,
unsigned int end, gfp_t flags);
unsigned int nr_elements, gfp_t flags);
This function will ensure that memory for the elements indexed in the range
defined by start and end has been allocated. Thereafter, a
defined by start and nr_elements has been allocated. Thereafter, a
flex_array_put() call on an element in that range is guaranteed not to
block.

* Date: Fri Dec 17 16:58:28 2010 -0800
*
* x86-64, mm: Put early page table high
*
* at some point init_memory_mapping is going to reach the pagetable pages
* area and map those pages too (mapping them as normal memory that falls
* in the range of addresses passed to init_memory_mapping as argument).
* Some of those pages are already pagetable pages (they are in the range
* pgt_buf_start-pgt_buf_end) therefore they are going to be mapped RO and
* everything is fine.
* Some of these pages are not pagetable pages yet (they fall in the range
* pgt_buf_end-pgt_buf_top; for example the page at pgt_buf_end) so they
* are going to be mapped RW. When these pages become pagetable pages and
* are hooked into the pagetable, xen will find that the guest has already
* a RW mapping of them somewhere and fail the operation.
* The reason Xen requires pagetables to be RO is that the hypervisor needs
* to verify that the pagetables are valid before using them. The validation
* operations are called "pinning".
*
* In order to fix the issue we mark all the pages in the entire range
* pgt_buf_start-pgt_buf_top as RO, however when the pagetable allocation
* is completed only the range pgt_buf_start-pgt_buf_end is reserved by
* init_memory_mapping. Hence the kernel is going to crash as soon as one
* of the pages in the range pgt_buf_end-pgt_buf_top is reused (b/c those
* ranges are RO).
*
* For this reason, 'mark_rw_past_pgt' is introduced which is called _after_
* the init_memory_mapping has completed (in a perfect world we would
* call this function from init_memory_mapping, but lets ignore that).
*
* Because we are called _after_ init_memory_mapping the pgt_buf_[start,
* end,top] have all changed to new values (b/c init_memory_mapping
* is called and setting up another new page-table). Hence, the first time
* we enter this function, we save away the pgt_buf_start value and update
* the pgt_buf_[end,top].
*
* When we detect that the "old" pgt_buf_start through pgt_buf_end
* PFNs have been reserved (so memblock_x86_reserve_range has been called),
* we immediately set out to RW the "old" pgt_buf_end through pgt_buf_top.
*
* And then we update those "old" pgt_buf_[end|top] with the new ones
* so that we can redo this on the next pagetable.
