The patch titled:"xen/blkback: Use 'vzalloc' for page arrays and pre-allocate pages." allocates the structures and its member variables using the 'vzalloc'. Daniel Stodden pointed out that vzalloc is good when we use big number of pages - while these are at the max two pages. We can do this using kzalloc. Also the GFP_HIGHMEM does not work properly with Xen, so take that out. We will have to revisit this when a "get_empty_pages_and_pagevec" type API shows up to leverage that.

Previously we would allocate the array for page using 'kmalloc' which we can as easily do with 'vzalloc'. The pre-allocation of pages was done a bit differently in the past - it used to be that the balloon driver would export "alloc_empty_pages_and_pagevec" which would have in one function created an array, allocated the pages, balloned the pages out (so the memory behind those pages would be non-present), and provide us those pages. This was OK as those pages were shared between other guest and the only thing we needed was to "swizzel" the MFN of those pages to point to the other guest MFN. We can still "swizzel" the MFNs using the M2P (and P2M) override API calls, but for the sake of simplicity we are dropping the balloon API calls. We can return to those later on.

Following in the steps of patch: "xen: Union the blkif_request request specific fields" this patch changes the blkback. Per the original patch: "Prepare for extending the block device ring to allow request specific fields, by moving the request specific fields for reads, writes and barrier requests to a union member."

Cherry-pick and modified from 69d64727c42eecd47fdf82c15a54474d21a4012a ("blkback/blktap2: simplify address translations"): "There are quite a number of places where e.g. page->va->page translations happen. Besides yielding smaller code (source and binary), a second goal is to make it easier to determine where virtual addresses of pages allocated through alloc_empty_pages_and_pagevec() are really used (in turn in order to determine whether using highmem pages would be possible there)." The second goal is not the purpose of this patch - it is just to make it easier to read the code. linux-2.6-pvops: * Stripped drivers/xen/gntdev/* * Stripped drivers/xen/netback/* [v2: Stripped blktap off] Signed-off-by: NJan Beulich <jbeulich@novell.com> Signed-off-by: NDaniel Stodden <daniel.stodden@citrix.com> Signed-off-by: NJeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Signed-off-by: NKonrad Rzeszutek Wilk <konrad.wilk@oracle.com>

A guest can cause the backend driver to leak a kernel thread. Such leaked threads hold references to the device, whichmakes the device impossible to tear down. If shut down, the guest remains a zombie domain, the xenwatch process hangs, and most xm commands will stop working. This patch tries to do the following for blkback: - identify/extract idempotent teardown operations, - add/move the invocation of said teardown operation right before we're about to allocate new resources in the Connected states.

In commit 13583b16 ("PCI: refactor io size calculation code") Ram had a thinko in the refactorization of the code: the end result used the variable 'align' for the bus alignment, but the original code used 'min_align'. Since then, another use of that 'align' variable got introduced by commit c8adf9a3 ("PCI: pre-allocate additional resources to devices only after successful allocation of essential resources.") Fix both of those uses to use 'min_align' as they should.
