a) if you initialize something with le32_to_cpu(...), then |= it with host-endian and feed to cpu_to_le32(), it's most definitely *not* __le32. As sparse would've told you... b) the whole sequence is |= cpu_to_le32(host-endian constant) Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2008-04-03[TG3]: Add PHY workaround for 5784Matt Carlson
The 5784 B step and newer chips require the PHY DSPs to be fine-tuned based on one-time programmable values stored in the chip. This is essential to achieve optimal PHY operations especially when using long cables. We also need to properly handle the 10Mbit RX bit in the CPMU_CTRL register during PHY reset. Update version to 3.89. Signed-off-by: Matt Carlson <mcarlson@broadcom.com> Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-04-03[POWERPC] Fix MPC5200 (not B!) device tree so FEC ethernet worksRené Bürgel
This gets the FEC ethernet driver working again on the lite5200 platform. The FEC driver is also compatible with the MPC5200, not only with the MPC5200B, so this adds a suitable entry to the driver's match list. Furthermore this adds the settings for the PHY in the dts file for the Lite5200. Note, that this is not exactly the same as in the Lite5200B, because the PHY is located at f0003000:01 for the 5200, and at :00 for the 5200B. This was tested on a Lite5200 and a Lite5200B, both booted a kernel via tftp and mounted the root via nfs successfully.

2008-04-01plip: replace spin_lock_irq with spin_lock_irqsave in irq contextMikulas Patocka
Plip uses spin_lock_irq/spin_unlock_irq in its IRQ handler (called from parport IRQ handler), the latter enables interrupts without parport subsystem IRQ handler expecting it. The bug can be seen if you compile kernel with lock dependency checking and use plip --- it produces a warning. This patch changes it to spin_lock_irqsave/spin_lock_irqrestore, so that it doesn't enable interrupts when already disabled. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-03-28[netdrvr] tulip_read_eeprom fixes for BUG 4420Grant Grundler
If "location" is > "addr_len" bits, the high bits of location would interfere with the READ_CMD sent to the eeprom controller. A patch was submitted to bug: http://bugzilla.kernel.org/show_bug.cgi?id=4420 which simply truncated the "location", read whatever was in "location modulo addr_len", and returned that value. That avoids confusing the eeprom but seems like the wrong solution to me. Correct would be to not read beyond "1 << addr_len" address of the eeprom. I am submitting two changes to implement this: 1) tulip_read_eeprom will return zero (since we can't return -EINVAL) if this is attempted (defensive programming). 2) In tulip_core.c, fix the tulip_read_eeprom caller so they don't iterate past addr_len bits and make sure the entire tp->eeprom[] array is cleared. I konw we don't strictly need both. I would prefer both in the tree since it documents the issue and provides a second "defense" from the bug from creeping back in.

2008-03-27rt2x00: Ignore set_state(STATE_SLEEP) failureIvo van Doorn
Some hardware never seem to accept the "goto sleep" command, since the legacy drivers don't have suspend and resume handlers the entire code for it was basically a educated guess (based on the "enable radio" code). This patch will only print a warning when the "goto sleep" command fails, and just continues as usual. Perhaps that means the device will not reach a sleep state and consumes more power then it should, but it is equally possible it simply needs some seconds longer to sleep. Anyway, by making the command non-fatal it will not block the rest of the suspend procedure. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

In commit e6bafba5b4765a5a252f1b8d31cbf6d2459da337, a bug was fixed that involved converting !x & y to !(x & y).

This is technically a false positive, since the uses in sge.c are only in the initialization and cleanup paths and cannot overlap with any use in interrupt context. The best fix is probably just to use spin_lock_irq() with reg_lock in sge.c. Even though it's not strictly required for correctness, it avoids triggering lockdep and the extra overhead of disabling interrupts is not important at all in the initialization and cleanup slow paths.
