| * [LINUX] Make xen /dev/mem aware of IA64 to use X.kfraser@localhost.localdomain2006-11-223-16/+41
| | | | | | | | | | | | | | | | | | | | The original /dev/mem (linux/drivers/char/mem.c) is aware of IA64 specific issues. On the other hand paravirtualized /dev/mem (linux-2.6-xen-sparse/drivers/xen/char/mem.c) is simplifed not to be aware of IA64. This patch makes it IA64-aware to use X on domain0/IA64.

| * | [LINUX] Fix clear_fixmap().kfraser@localhost.localdomain2006-11-132-5/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On i386-PAE, clear_fixmap() results in ill use of set_pte(). In all contexts, p2m translations shouldn't occur here. Note that this is not really an issue on native linux, as there is (a) no pfn-to-mfn translation and (b) __set_fixmap() takes an unsigned long physical address rather than a paddr_t, which makes it so that bits 32 and up of the physical address are always zero, permitting either order store when clearing the entry.

The value can be 1 (all is fine) or 0 (underlying block device doesn't support barriers). blkback changes: Add "feature-barrier" node to indicate barrier support, pass incoming barrier requests to the block layer using submit_bio(WRITE_BARRIER, bio). Some error handling fixes to properly pass through barrier write failures, so the frontend can turn off barriers then. blkfront changes: Check if the backend sets "feature-barrier", if present switch to QUEUE_ORDERED_DRAIN mode. Send off barrier requests to the backend using the new BLKIF_OP_WRITE_BARRIER operation. Also some error handling for the EOPNOTSUPP case. Background: Barriers are needed to make journaling filesystems work reliable. For some requests they need order constrains to make the transactions work correctly. Barrier requests are used to pass that ordering information to the block layer and/or to the device, so the constrains are obeyed when reordering requests for better write performance.
