This patch has been running inside SGI for 2 months. It handles kernel stacks with multiple struct pt_regs, as found while debugging the kernel.

This version executes in around 300 cycles on Itanium I (down from 900 or so for the original version), and so can be said to have microsecond precision.

Here is the patch that matches the changes I made for RHAS w.r.t perfmon and the O(1) scheduler. This fixes the deadlocks we were seing in RHAS and therefore on 2.5 as well. The key change is that SIGPROF notifications are now delivered in the perfmon kernel exit handler (called from entry.S). At that point, we know none of the runqueue locks are held. I have run the same test suite I used on RHAS overnight and no sign of deadlocks.

Mikulas Patocka <mikulas@artax.karlin.mff.cuni.cz> points out a bug in ll_rw_block() usage. Typical usage is: mark_buffer_dirty(bh); ll_rw_block(WRITE, 1, &bh); wait_on_buffer(bh); the problem is that if the buffer was locked on entry to this code sequence (due to in-progress I/O), ll_rw_block() will not wait, and start new I/O. So this code will wait on the _old_ I/O, and will then continue execution, leaving the buffer dirty. It turns out that all callers were only writing one buffer, and they were all waiting on that writeout. So I added a new sync_dirty_buffer() function: void sync_dirty_buffer(struct buffer_head *bh) { lock_buffer(bh); if (test_clear_buffer_dirty(bh)) { get_bh(bh); bh->b_end_io = end_buffer_io_sync; submit_bh(WRITE, bh); } else { unlock_buffer(bh); } } which allowed a fair amount of code to be removed, while adding the desired data-integrity guarantees. UFS has its own wrappers around ll_rw_block() which got in the way, so this operation was open-coded in that case.

This removes lots of annoying problems trying to prevent both modules from being loaded, and also shares quite a bit of code. CONFIG_AGP3 will disable AGP3 mode operation of KT400s.

Based upon information from VIA, this also adds a bunch of placeholder entries that will get filled in over time when they have been proven to work with the code with no extra modification.

The AGP3 spec allows for >1 AGP bus. This is the first of several patches from Jeff Hartmann towards a context-using agp_bridge, by replacing agp_bridge.foo accesses with agp_bridge->foo accesses. For now, there should be no functional differences, as there is still only a single agp_bridge_data struct defined.
