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.

2008-05-02tg3: Fix ethtool loopback test for 5761 BX devicesMatt Carlson
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. This patch disables the CPMU LINK_SPEED mode just like we do with the AX revisions of the 5761 and all revisions of the 5784.

2008-05-02tg3: Fix 5761 NVRAM sizesMatt Carlson
The 5761 NVRAM sizes assigned to the nvram_size member are half as big as they should be. This patch corrects the NVRAM sizes and replaces the hardcoded constants with preprocessor constants for readability.

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.

WARN_ON_ONCE() gives a stack trace including the full module list.

2008-04-30Fix dnotify/close raceAl Viro
We have a race between fcntl() and close() that can lead to dnotify_struct inserted into inode's list *after* the last descriptor had been gone from current->files. Since that's the only point where dnotify_struct gets evicted, we are screwed - it will stick around indefinitely. Even after struct file in question is gone and freed. Worse, we can trigger send_sigio() on it at any later point, which allows to send an arbitrary signal to arbitrary process if we manage to apply enough memory pressure to get the page that used to host that struct file and fill it with the right pattern...

2008-04-30x86: Mark OPTIMIZE_INLINING brokenLinus Torvalds
So Ingo finally did figure out why UML broke with this option: UML passes gcc the -fno-unit-at-a-time flag, and apparently that wreaks havoc with gcc's inlining. We could turn off -fno-unit-at-a-time for UML for gcc4+ (which is what x86 does), but there's bad blood about this whole option, and it does show that the thing is just fragile as heck. So let tempers cool, and disable the thing, and we can revisit the decision later.
