This patch implements the interposing DMA mapping functions to allow support for IOMMUs and remove the dependence on phys_to_virt() and bus_to_virt(). Signed-off-by: Ralph Campbell <ralph.campbell@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

Ralph Campbell authored
The QLogic InfiniPath HCAs use programmed I/O instead of HW DMA. This patch allows a verbs device driver to interpose on DMA mapping function calls in order to avoid relying on bus_to_virt() and phys_to_virt() to undo the mappings created by dma_map_single(), dma_map_sg(), etc. Signed-off-by: Ralph Campbell <ralph.campbell@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

During connection establishment, the passive side of a connection can receive messages from the active side before the connection event has been delivered to the user. Allow the passive side to send messages in response to received data before the event is delivered. To handle the case where the connection messages are lost, a new rdma_notify() function is added that users may invoke to force a connection into the established state.

Commit 51f65ebc ("IB/ipath - program intconfig register using new HT irq hook"), which fixed interrupts for HyperTransport HCAs, broke PCI Express HCAs, because for those HCAs, the driver uses the value of pdev->irq before pci_enable_msi() and ends up getting a totally bogus IRQ number. Fix this by using the value of pdev->irq after pci_enable_msi(). Signed-off-by: Roland Dreier <rolandd@cisco.com>

ib_flush_fmr_pool() stashes away the request generation number properly, but then goes ahead and rereads it every time it tests whether the flush generation number has caught up. This means that there is a theoretical possibility of livelock, if the request generation number keeps getting bumped and the flush generation number never catches up. The fix is simple: use the request generation number read at the beginning of the function. Also, atomic_inc() followed by atomic_read() can be replaced with atomic_int_return(). There's no real requirement for atomicity here but we might as well shrink the code. This bug was discovered using David Binderman's list of "set but never used" warnings from icc.

seqlock_init() needs to use spin_lock_init() for dynamic locks, so that lockdep is notified about the presence of a new lock. (this is a fallout of the recent networking merge, which started using the so-far unused seqlock_init() API.) This fix solves the following lockdep-internal warning on current -git: INFO: trying to register non-static key. the code is fine but needs lockdep annotation. turning off the locking correctness validator. __lock_acquire+0x10c/0x9f9 lock_acquire+0x56/0x72 _spin_lock+0x35/0x42 neigh_destroy+0x9d/0x12e neigh_periodic_timer+0x10a/0x15c run_timer_softirq+0x126/0x18e __do_softirq+0x6b/0xe6 do_softirq+0x64/0xd2 ksoftirqd+0x82/0x138 Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

While working on bidi support at struct request level I have found that blk_queue_activity_fn is actually never used. The only user is in ide-probe.c with this code: /* enable led activity for disk drives only */ if (drive->media == ide_disk && hwif->led_act) blk_queue_activity_fn(q, hwif->led_act, drive); And led_act is never initialized anywhere. (Looking back at older kernels it was used in the PPC arch, but was removed around 2.6.18) Unless it is all for future use off course.

This patch makes paging_init() use highend_pfn/highstart_pfn globals. It removes the need of 'high' local which was needed only by HIGHMEM config. More important perhaps, it fixes a bug when HIGHMEM is set but there's actually no physical highmem (highend_pfn = 0) Signed-off-by: Franck Bui-Huu <fbuihuu@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

While the recent cset 86384d54 did improve things it didn't resolve all the problems. So bite the bullet and discard .exit.text and .exit.data at runtime. Which of course sucks because it bloats binaries with code that will never ever be used but it's the only thing that will work reliable as demonstrated by the function sd_major() in drivers/scsi/sd.c. Gcc may compile sd_major() using a jump table which it will put into .rodata. If it also inlines sd_major's function body into exit_sd() which gcc > 3.4.x does. If CONFIG_BLK_DEV_SD has been set to y we would like ld to discard exit_sd's code at link time. However sd_major happens to contain a switch statement which gcc will compile using a jump table in .rodata on the architectures I checked. So, when ld later discards .exit.text only the jump table in .rodata with its stale references to the discard .exit.text will be left which any no antique ld will honor with a link error.
