* [SPARC64]: Internalize pci_memspace_mask.David S. Miller2007-04-26
| | | | | | | | | The only user was bus_dvma_to_mem() which is no longer used by any driver, so kill that, and the export of pci_memspace_mask. The only user now is the PCI mmap support code. Signed-off-by: David S. Miller <davem@davemloft.net>

* [SPARC64]: Add clocksource/clockevents support.David S. Miller2007-04-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I'd like to thank John Stul and others for helping me along the way. A lot of cleanups fell out of this. For example, the get_compare() tick_op was totally unused, so was deleted. And the most often used tick_op members were grouped together for cache-friendlyness. The sparc64 TSC is given to the kernel as a one-shot timer. tick_ops->init_timer() simply turns off the privileged bit in the tick register (when possible), and disables the interrupt by setting bit 63 in the compare register. The ->disable_irq() op also sets this bit. tick_ops->add_compare() is changed to: 1) Add the given delta to "tick" not to "compare" 2) Return a boolean which, if true, means that the tick value read after writing the compare value was found to have incremented past the initial tick value. This mirrors logic used in the HPET driver's ->next_event() method. Each tick_ops implementation also now provides a name string. And we feed this into the clocksource and clockevents layers.

* | | packet: fix error handlingAndrew Morton2007-04-25
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The packet driver is assuming (reasonably) that the (undocumented) request.errors is an errno. But it is in fact some mysterious bitfield. When things go wrong we return weird positive numbers to the VFS as pointers and it goes oops. Thanks to William Heimbigner for reporting and diagnosis.

* | cfq-iosched: fix alias + front merge bugJens Axboe2007-04-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a really rare and obscure bug in CFQ, that causes a crash in cfq_dispatch_insert() due to rq == NULL. One example of the resulting oops is seen here: http://lkml.org/lkml/2007/4/15/41 Neil correctly diagnosed the situation for how this can happen: if two concurrent requests with the exact same sector number (due to direct IO or aliasing between MD and the raw device access), the alias handling will add the request to the sortlist, but next_rq remains NULL. Read the more complete analysis at: http://lkml.org/lkml/2007/4/25/57 This looks like it requires md to trigger, even though it should potentially be possible to due with O_DIRECT (at least if you edit the kernel and doctor some of the unplug calls). The fix is to move the ->next_rq update to when we add a request to the rbtree. Then we remove the possibility for a request to exist in the rbtree code, but not have ->next_rq correctly updated.

Setting carrier to off based on the NO_CARRIER flag is also incorrect as that flag only triggers on TX failure and therefore isn't correct when no frames are being transmitted. Since there is already a 2*HZ MII carrier check going on, defer to that. Add a TRUST_LINK_STATUS feature flag for adapters where the LINK_STATUS flag is actually correct, and use that rather than the NO_CARRIER flag.

| * | sis900: Allocate rx replacement buffer before rx operationNeil Horman2007-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sis900 driver appears to have a bug in which the receive routine passes the skbuff holding the received frame to the network stack before refilling the buffer in the rx ring. If a new skbuff cannot be allocated, the driver simply leaves a hole in the rx ring, which causes the driver to stop receiving frames and become non-recoverable without an rmmod/insmod according to reporters. This patch reverses that order, attempting to allocate a replacement buffer first, and receiving the new frame only if one can be allocated. If no skbuff can be allocated, the current skbuf in the rx ring is recycled, dropping the current frame, but keeping the NIC operational.

We don't use a dynamic pointer for pldev->dev.platform_data, so it seems that the correct way to proceed if platform_device_add(pldev) fails is to explicitly set the pldev->dev.platform_data pointer to NULL, before calling the platform_device_put(pldev), or it will be kfree'ed by platform_device_release().
