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>

struct srp_device.fmr_page_mask was unsigned long, which means that the top part of addresses above 4G was being chopped off on 32-bit architectures. Of course nothing good happens when data from SRP targets is DMAed to the wrong place. Fix this by changing fmr_page_mask to u64, to match the addresses actually used by IB devices.

The ib_dma_alloc_coherent() wrapper uses a u64* for the dma_handle parameter, unlike dma_alloc_coherent, which uses dma_addr_t*. This means that we need a temporary variable to handle the case when ib_dma_alloc_coherent() just falls through directly to dma_alloc_coherent() on architectures where sizeof u64 != sizeof dma_addr_t.

Reboot hangs on LPARs without diag308 support. The reason for this is, that before the reboot is done, the channel subsystem is shut down. During the reset on each possible subchannel a "store subchannel" is done. This operation can end in a program check interruption, if the specified subchannel set is not implemented by the hardware. During the reset, currently we do not have a program check handler, which leads to the described kernel bug. We install now a new program check handler for the reboot code to fix this problem.

Currently in SCTP, we maintain a local address list by rebuilding the whole list from the device list whenever we get a address add/delete event. This patch fixes it by only adding/deleting the address for which we receive the event. Also removed the sctp_local_addr_lock() which is no longer needed as we now use list_for_each_safe() to traverse this list. This fixes the bugs in sctp_copy_laddrs_xxx() routines where we do copy_to_user() while holding this lock. Signed-off-by: NSridhar Samudrala <sri@us.ibm.com> Signed-off-by: NDavid S.
