This reverts commits 11012d41 and 40dd2d20, which allowed us to use the MMIO accesses for PCI config cycles even without the area being marked reserved in the e820 memory tables. Those changes were needed for EFI-environment Intel macs, but broke some newer Intel 965 boards, so for now it's better to revert to our old 2.6.17 behaviour and at least avoid introducing any new breakage. Andi Kleen has a set of patches that work with both EFI and the broken Intel 965 boards, which will be applied once they get wider testing.

while porting the -rt tree to 2.6.18-rc7 i noticed the following screaming-IRQ scenario on an SMP system: 2274 0Dn.:1 0.001ms: do_IRQ+0xc/0x103 <= (ret_from_intr+0x0/0xf) 2274 0Dn.:1 0.010ms: do_IRQ+0xc/0x103 <= (ret_from_intr+0x0/0xf) 2274 0Dn.:1 0.020ms: do_IRQ+0xc/0x103 <= (ret_from_intr+0x0/0xf) 2274 0Dn.:1 0.029ms: do_IRQ+0xc/0x103 <= (ret_from_intr+0x0/0xf) 2274 0Dn.:1 0.039ms: do_IRQ+0xc/0x103 <= (ret_from_intr+0x0/0xf) 2274 0Dn.:1 0.048ms: do_IRQ+0xc/0x103 <= (ret_from_intr+0x0/0xf) 2274 0Dn.:1 0.058ms: do_IRQ+0xc/0x103 <= (ret_from_intr+0x0/0xf) 2274 0Dn.:1 0.068ms: do_IRQ+0xc/0x103 <= (ret_from_intr+0x0/0xf) 2274 0Dn.:1 0.077ms: do_IRQ+0xc/0x103 <= (ret_from_intr+0x0/0xf) 2274 0Dn.:1 0.087ms: do_IRQ+0xc/0x103 <= (ret_from_intr+0x0/0xf) 2274 0Dn.:1 0.097ms: do_IRQ+0xc/0x103 <= (ret_from_intr+0x0/0xf) as it turns out, the bug is caused by handle_level_irq(), which if it races with another CPU already handling this IRQ, it _unmasks_ the IRQ line on the way out. This is not how 2.6.17 works, and we introduced this bug in one of the early genirq cleanups right before it went into -mm. (the bug was not in the genirq patchset for a long time, and we didnt notice the bug due to the lack of -rt rebase to the new genirq code. -rt, and hardirq-preemption in particular opens up such races much wider than anything else.)

This is a tidy up of the GFS2 bmap code. The main change is that the bh is passed to gfs2_block_map allowing the flags to be set directly rather than having to repeat that code several times in ops_address.c. At the same time, the extent mapping code from gfs2_extent_map has been moved into gfs2_block_map. This allows all calls to gfs2_block_map to map extents in the case that no allocation is taking place. As a result reads and non-allocating writes should be faster. A quick test with postmark appears to support this. There is a limit on the number of blocks mapped in a single bmap call in that it will only ever map blocks which are pointed to from a single pointer block. So in other words, it will never try to do additional i/o in order to satisfy read-ahead. The maximum number of blocks is thus somewhat less than 512 (the GFS2 4k block size minus the header divided by sizeof(u64)). I've further limited the mapping of "normal" blocks to 32 blocks (to avoid extra work) since readpages() will currently read a maximum of 32 blocks ahead (128k). Some further work will probably be needed to set a suitable value for DIO as well, but for now thats left at the maximum 512 (see ops_address.c:gfs2_get_block_direct). There is probably a lot more that can be done to improve bmap for GFS2, but this is a good first step. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

If the user tries to traverse to the next node of the last node, we get NULL in current_node and a zero phandle returned.

This turns out to be a genuine bug. The queue lock and xmit lock are intentionally taken out of order. Two things are supposed to prevent dead-locks from occuring: 1) When we hold the queue_lock we're supposed to only do try_lock on the tx_lock. 2) We always drop the queue_lock after taking the tx_lock and before doing anything else. > > the existing dependency chain (in reverse order) is: > > -> #1 (&dev->_xmit_lock){-+..}: > [<c012e7b6>] lock_acquire+0x76/0xa0 > [<c0336241>] _spin_lock_bh+0x31/0x40 > [<c02d25a9>] dev_activate+0x69/0x120 This path obviously breaks assumption 1) and therefore can lead to ABBA dead-locks. I've looked at the history and there seems to be no reason for the lock to be held at all in dev_watchdog_up. The lock appeared in day one and even there it was unnecessary. In fact, people added __dev_watchdog_up precisely in order to get around the tx lock there. The function dev_watchdog_up is already serialised by rtnl_lock since its only caller dev_activate is always called under it. So here is a simple patch to remove the tx lock from dev_watchdog_up. In 2.6.19 we can eliminate the unnecessary __dev_watchdog_up and replace it with dev_watchdog_up. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au> Signed-off-by: NDavid S.
