2006-03-28[TG3]: Speed up SRAM accessMichael Chan
Speed up SRAM read and write functions if possible by using MMIO instead of config. cycles. With this change, the post reset signature done at the end of D3 power change must now be moved before the D3 power change. IBM reported a problem on powerpc blades during ethtool self test that was caused by the memory test taking excessively long. Config. cycles are very slow on powerpc and the memory test can take more than 10 seconds to complete using config. cycles. As a result, NETDEV WATCHDOG can be triggered during self test and the chip can end up in a funny state. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.

2006-03-28[TG3]: Fix probe failure due to invalid MAC addressMichael Chan
Some older bootcode in some devices may report 0 MAC address in SRAM when booting up from low power state. This patch fixes the problem by checking for a valid MAC address in SRAM and falling back to NVRAM if necessary.

2006-03-28sbp2: check for ARM failureStefan Richter
Sbp2 did not check for successful registration of the lower address range when CONFIG_IEEE1394_SBP2_PHYS_DMA was set. If hpsb_register_addrspace failed, a "login timed-out" would occur which is misleading. Now sbp2 logs a sensible error message.

2006-03-28sbp2: prevent unloading of 1394 low-level driverStefan Richter
When a new SBP-2 unit is added, sbp2 now takes a reference on the 1394 low-level driver (ohci1394 or pcilynx). This prevents the 1394 host driver module from being unloaded, e.g. by an administrative routine cleanup of unused kernel modules or when another 1394 driver which depends on ohci1394 is unloaded. The reference is dropped when the SBP-2 unit was disconnected, when sbp2 is unloaded or detached from the unit, or when addition of the SBP-2 unit failed.

This is a conversion to make the various file_operations structs in fs/ const.

2006-03-28[PATCH] Small fixes backported to old IDE SiS driverAlan Cox
Some quick backport bits from the libata PATA work to fix things found in the sis driver. The piix driver needs some fixes too but those are way to large and need someone working on old IDE with time to do them. This patch fixes the case where random bits get loaded into SIS timing registers according to the description of the correct behaviour from Vojtech Pavlik. It also adds the SiS5517 ATA16 chipset which is not currently supported by the driver. Thanks to Conrad Harriss for loaning me the machine with the 5517 chipset.

2006-03-28[PATCH] powerpc: Kill _machine and hard-coded platform numbersBenjamin Herrenschmidt
This removes statically assigned platform numbers and reworks the powerpc platform probe code to use a better mechanism. With this, board support files can simply declare a new machine type with a macro, and implement a probe() function that uses the flattened device-tree to detect if they apply for a given machine. We now have a machine_is() macro that replaces the comparisons of _machine with the various PLATFORM_* constants. This commit also changes various drivers to use the new macro instead of looking at _machine.

raid5 overloads bi_phys_segments to count the number of blocks that the request was broken in to so that it knows when the bio is completely handled. Accessing this must always be done under a spinlock. In one case we also call bi_end_io under that spinlock, which probably isn't ideal as bi_end_io could be expensive (even though it isn't allowed to sleep). So we reducde the range of the spinlock to just accessing bi_phys_segments.
