Reschedule code to read ar.bsp as early as possible. To enable this, don't bother clearing some of the registers when we're returning to kernel stacks. Also, instead of trying to support the pNonSys case (which makes no sense), do a bugcheck instead (with break 0). Finally, remove a clear of r14 which is a left-over from the previous patch.

Using stf8 seemed like a clever idea at the time, but stf8 forces the cache-line to be invalidated in the L1D (if it happens to be there already). This patch eliminates a guaranteed L1D cache-miss and, by itself, is good for a 1-2 cycle improvement for heavy-weight syscalls.

Why is this a good idea? Clearing b7 to 0 is guaranteed to do us no good and writing it with __kernel_syscall_via_epc() yields a 6 cycle improvement _if_ the application performs another EPC-based system- call without overwriting b7, which is not all that uncommon. Well worth the minimal cost of 1 bundle of code. Signed-off-by: David Mosberger-Tang <davidm@hpl.hp.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

This by itself is good for a 1-2 cycle speed up. Effect is bigger when combined with the later patches. Signed-off-by: David Mosberger-Tang <davidm@hpl.hp.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

Call pci_enable_device() before looking at IRQ and resources, and pci_disable_device() when shutting the interface down. The driver requires this fix or the "pci=routeirq" workaround on 2.6.10 and later kernels. Reported and tested by Artur Lipowski.

This is a fix to the pgtable_quicklist code. There is a GFP_KERNEL allocation in pgtable_quicklist_alloc(), which spews the usual warnings if the kernel is under heavy VM pressure and the reclaim code is invoked. re-enable preempt before we allocate the new page. This patch is against 2.6.12-rc2-mm2 Signed-off-by: Martin Hicks <mort@sgi.com> Signed-off-by: Tony Luck <tony.luckintel.com>

A lot of places in there are including major.h for no reason whatsoever. Removed. And yes, it still builds. The history of that stuff is often amusing. E.g. for net/core/sock.c the story looks so, as far as I've been able to reconstruct it: we used to need major.h in net/socket.c circa 1.1.early. In 1.1.13 that need had disappeared, along with register_chrdev(SOCKET_MAJOR, "socket", &net_fops) in sock_init(). Include had not. When 1.2 -> 1.3 reorg of net/* had moved a lot of stuff from net/socket.c to net/core/sock.c, this crap had followed...
