2008-05-07sparc: Fix SA_ONSTACK signal handling.David S. Miller
We need to be more liberal about the alignment of the buffer given to us by sigaltstack(). The user should not need to be mindful of all of the alignment constraints we have for the stack frame. This mirrors how we handle this situation in clone() as well. Also, we align the stack even in non-SA_ONSTACK cases so that signals due to bad stack alignment can be delivered properly. This makes such errors easier to debug and recover from. Finally, add the sanity check x86 has to make sure we won't overflow the signal stack. This fixes glibc testcases nptl/tst-cancel20.c and nptl/tst-cancelx20.c Signed-off-by: David S. Miller <davem@davemloft.net>
2008-05-07sparc: Fix fork/clone/vfork system call restart.David S. Miller
We clobber %i1 as well as %i0 for these system calls, because they give two return values. Therefore, on error, we have to restore %i1 properly or else the restart explodes since it uses the wrong arguments. This fixes glibc's nptl/tst-eintr1.c testcase. Signed-off-by: David S.

2008-05-03tiny mq_open optimizationUlrich Drepper
A very small cleanup for mq_open. We do not have to call set_close_on_exit if we create the file descriptor right away with the flag set. We have a function for this now.

2008-05-03unified (weak) sys_pipe implementationUlrich Drepper
This replaces the duplicated arch-specific versions of "sys_pipe()" with one unified implementation. This removes almost 250 lines of duplicated code. It's marked __weak, so that *if* an architecture wants to override the default implementation it can do so by simply having its own replacement version, since many architectures use alternate calling conventions for the 'pipe()' system call for legacy reasons (ie traditional UNIX implementations often return the two file descriptors in registers) I still haven't changed the cris version even though Linus says the BKL isn't needed. The arch maintainer can easily do it if there are really no obstacles. Signed-off-by: Ulrich Drepper <drepper@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-05-02netns: Fix device renaming for sysfsDaniel Lezcano
When a netdev is moved across namespaces with the 'dev_change_net_namespace' function, the 'device_rename' function is used to fixup kobject and refresh the sysfs tree. The device_rename function will call kobject_rename and this one will check if there is an object with the same name and this is the case because we are renaming the object with the same name. The use of 'device_rename' seems for me wrong because we usually don't rename it but just move it across namespaces. As we just want to do a mini "netdev_[un]register", IMO the functions 'netdev_[un]register_kobject' should be used instead, like an usual network device [un]registering. This patch replace device_rename by netdev_unregister_kobject, followed by netdev_register_kobject. The netdev_register_kobject will call device_initialize and will raise a warning indicating the device was already initialized. In order to fix that, I split the device initialization into a separate function and use it together with 'netdev_register_kobject' into register_netdevice. So we can safely call 'netdev_register_kobject' in 'dev_change_net_namespace'. This fix will allow to properly use the sysfs per namespace which is coming from -mm tree.

2008-05-02bnx2: Update RV2P firmware for 5709.Michael Chan
The new RV2P firmware fixes 2 issues: 1. The jumbo rx buffer page size is now configurable and set to the proper PAGE_SIZE. Before, it was assumed to be always 4K. 2. Driver sometimes would crash when receiving jumbo packets mixed with firmware management packets. This was caused by the old firmware DMA'ing to the wrong address.

2008-05-02bnx2: Fix remote PHY initial link state.Michael Chan
On some remote PHY blade systems, the driver receives no initial link interrupt. As a result, the GMII/MII MAC mode does not get setup properly.

2008-05-02bridge: forwarding table information for >256 devicesStephen Hemminger
The forwarding table binary interface (my bad choice), only exposes the port number of the first 8 bits. The bridge code was limited to 256 ports at the time, but now the kernel supports up 1024 ports, so the upper bits are lost when doing: brctl showmacs The fix is to squeeze the extra bits into small hole left in data structure, to maintain binary compatiablity.

2008-05-02tg3: Add link state reporting to UMP firmwareMatt Carlson
All variants of the 5714, 5715, and 5780 offer a feature called the "Universal Management Port". This feature is implemented in firmware and is largely transparent to the driver, except... It turns out that the UMP firmware needs to know the current status of the link. Because the firmware cannot touch the PHY registers while the driver is in control of the device, it needs the driver to report link status changes through an additional handshaking mechanism. Without this handshake, it has been observed in the field that the UMP firmware will not operate correctly. This patch implements the new handshake with the UMP firmware. Since the handshake uses the same mechanism ASF heartbeats use, code was added to detect and wait for completion of a pending previous event.

A CPMU related loopback test bug existed for AX revisions of the 5761. While that errata has been fixed, the CPMU still slows down the core clock too far to run the loopback test successfully.

2008-05-02tg3: Use constant 500KHz MI clock on adapters with a CPMUMatt Carlson
The MI clock is not configured correctly on adapters with the CPMU present. The tg3 driver has code which statically sets the MI clock to be a fraction of the speed at which the core clock is running. However, the CPMU can change the adapter's core clock frequency based on operating conditions. Consequently, the MI will run slow when the core's clock has been slowed down. There is a new 500KHz constant frequency clock available on adapters with a CPMU. This patch removes the static core clock scaling and configures the MI clock to use this new 500KHz clock instead. Running the MI clock at slower speeds will not directly result in data corruption, but it does challenge the PHY read and write routine timeouts.
