| * [CRYPTO] geode: Fix not inplace encryptionSebastian Siewior2007-11-11
| | | | | | | | | | | | | | | | | | | | | | Currently the Geode AES module fails to encrypt or decrypt if the coherent bits are not set what is currently the case if the encryption does not occur inplace. However, the encryption works on my Geode machine _only_ if the coherent bits are always set.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix thinko in commit eaf559bf ("mlx4_core: Don't free special QPs in QP number bitmap"). The old commit had the logic exactly backwards and ended up freeing *only* special QPs, which not only left the original bug in place but also introduced the problem that the QP number bitmap would get full after a while.

| * | RDMA/cxgb3: Set the max_qp_init_rd_atom attribute in query_deviceSteve Wise2007-11-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The device attribute max_qp_init_rd_atom is not getting set in cxgb3's query_device method. Version 1.0.4 of librdmacm now validates the user's requested initiator and responder resources against the max supported by the device. Since iw_cxgb3 wasn't setting this attribute (and it defaulted to 0), all rdma_connect()s fail if there are initiator resources requested by the app. Fix this by setting the correct value in iwch_query_device().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The IPD (inter-packet delay) formula was a little off and assumed a fixed physical link rate; fix the formula and query the actual physical link rate, now that we can get it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an ACK is received, the QP is removed from the timeout list and then if there are still pending send WQEs, the QP is put back on the timeout list. It is possible that another post send has put the QP on the timeout list thus, a check needs to be made before trying to do it again or the list is corrupted.

This was not an error but the change simplifies debugging of address-space mappings. - Made myPrevRxDesc local to e100_rx since it was only used there. Fixed out of memory handling in e100_rx. If dev_alloc_skb() fails persistently the system is hosed anyway but at least it won't loop in an interrupt handler. - Correct some code formatting issues. - Add defines SET_ETH_ENABLE_LEDS, SET_ETH_DISABLE_LEDS and SET_ETH_AUTONEG used in new cris v10 ethernet driver.

This should not happen, as the ramdisk avoids freeing its pages by keeping them dirty all the time. It turns out that there is a case, where the VM makes a ramdisk page clean, without telling the ramdisk driver. On memory pressure shrink_zone runs and it starts to run shrink_active_list. There is a check for buffer_heads_over_limit, and if true, pagevec_strip is called. pagevec_strip calls try_to_release_page. If the mapping has no releasepage callback, try_to_free_buffers is called. try_to_free_buffers has now a special logic for some file systems to make a dirty page clean, if all buffers are clean. Thats what happened in our test case. The simplest solution is to provide a noop-releasepage callback for the ramdisk driver. This avoids try_to_free_buffers for ramdisk pages.

It is because that there is __no__ ACPI IRQ resource assigned for the serial port. So the value of the IRQ for the port is never changed since it got initialized to -1. If PNP supplies a valid IRQ, use it. Otherwise, leave port.irq == 0, which means "no IRQ" to the serial core.

* | | rtc: fall back to requesting only the ports we actually useBjorn Helgaas2007-11-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Firmware like PNPBIOS or ACPI can report the address space consumed by the RTC. The actual space consumed may be less than the size (RTC_IO_EXTENT) assumed by the RTC driver. The PNP core doesn't request resources yet, but I'd like to make it do so. If/when it does, the RTC_IO_EXTENT request may fail, which prevents the RTC driver from loading. Since we only use the RTC index and data registers at RTC_PORT(0) and RTC_PORT(1), we can fall back to requesting just enough space for those. If the PNP core requests resources, this results in typical I/O port usage like this: 0070-0073 : 00:06 <-- PNP device 00:06 responds to 70-73 0070-0071 : rtc <-- RTC driver uses only 70-71 instead of the current: 0070-0077 : rtc <-- RTC_IO_EXTENT == 8 Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Cc: Alessandro Zummo <a.zummo@towertech.it> Cc: David Brownell <david-b@pacbell.net> Cc: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for version 2 of the ioatdma device. This device handles the descriptor chain and DCA services slightly differently: - Instead of moving the dma descriptors between a busy and an idle chain, this new version uses a single circular chain so that we don't have rewrite the next_descriptor pointers as we add new requests, and the device doesn't need to re-read the last descriptor. - The new device has the DCA tags defined internally instead of needing them defined statically.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a DMA device is unregistered, its reference count is decremented twice for each channel: Once dma_class_dev_release() and once in dma_chan_cleanup(). This may result in the DMA device driver's remove() function completing before all channels have been cleaned up, causing lots of use-after-free fun. Fix it by incrementing the device's reference count twice for each channel during registration.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The pf driver for parallel port floppy drives seems to be broken. At least with Imation SuperDisk with EPAT chip, the driver calls pi_connect() and pi_disconnect after each transferred sector. At least with EPAT, this operation is very expensive - causes drive recalibration. Thus, transferring even a single byte (dd if=/dev/pf0 of=/dev/null bs=1 count=1) takes 20 seconds, making the driver useless. The pf_next_buf() function seems to be broken as it returns 1 always (except when pf_run is non-zero), causing the loop in do_pf_read_drq (and do_pf_write_drq) to be executed only once. The following patch fixes this problem. It also fixes swapped descriptions in pf_lock() function and removes DBMSG macro, which seems useless.
