tp->link_config.orig_* values must be assigned during tg3_set_settings() because these values will be used to setup the link speed during tg3_open(). Without these assignments, the link speed settings will be all messed by if tg3_set_settings() is called when the device is down.

There was an off-by-one bug in bnx2_tx_avail(). If the tx ring is completely full, the producer and consumer indices may be apart by 256 even though the ring size is only 255. One entry in the ring is unused and must be properly accounted for when calculating the number of available entries. The bug caused the tx ring entries to be reused by mistake, overwriting active entries, and ultimately causing it to crash. This bug rarely occurs because the tx ring is rarely completely full. We always stop when there is less than MAX_SKB_FRAGS entries available in the ring. Thanks to Corey Kovacs <cjk@techma.com> and Andy Gospodarek <agospoda@redhat.com> for reporting the problem and helping to collect debug information.

It branches around some necessary prom calls, which we would need to do even if we are mapped at the correct location already. So it doesn't work.

Hugh Dickins correctly points out that mincore() is actually _supposed_ to fail on an unmapped hole in the user address space, rather than return valid ("empty") information about the hole. This just simplifies the problem further (I had been misled by our previous confusing and complicated way of doing mincore()). Also, in the unlikely situation that we can't allocate a temporary kernel buffer, we should actually return EAGAIN, not ENOMEM, to keep the "unmapped hole" and "allocation failure" error cases separate. Finally, add a comment about our stupid historical lack of support for anonymous mappings. I'll fix that if somebody reminds me after 2.6.20 is out.

On architectures where the atomicity of the bit operations is handled by external means (ie a separate spinlock to protect concurrent accesses), just doing a direct assignment on the workqueue data field (as done by commit 4594bf15) can cause the assignment to be lost due to lack of serialization with the bitops on the same word. So we need to serialize the assignment with the locks on those architectures (notably older ARM chips, PA-RISC and sparc32). So rather than using an "unsigned long", let's use "atomic_long_t", which already has a safe assignment operation (atomic_long_set()) on such architectures. This requires that the atomic operations use the same atomicity locks as the bit operations do, but that is largely the case anyway. Sparc32 will probably need fixing. Architectures (including modern ARM with LL/SC) that implement sane atomic operations for SMP won't see any of this matter.

Doug Chapman noticed that mincore() will doa "copy_to_user()" of the result while holding the mmap semaphore for reading, which is a big no-no. While a recursive read-lock on a semaphore in the case of a page fault happens to work, we don't actually allow them due to deadlock schenarios with writers due to fairness issues. Doug and Marcel sent in a patch to fix it, but I decided to just rewrite the mess instead - not just fixing the locking problem, but making the code smaller and (imho) much easier to understand.

The UDMA66 VIA hardware has no controller side cable detect bits we can use. This patch minimally fixes the problem by reporting unknown in this case and using drive side detection. The old drivers/ide code does some additional tricks but those aren't appropriate now we are in -rc. Without this update UDMA66 via controllers run slowly. They don't fail so it's a borderline call whether this is -rc material or not. Signed-off-by: NAlan Cox <alan@redhat.com> Signed-off-by: NJeff Garzik <jeff@garzik.org>
