| * [SPARC64]: store-init needs trailing membar.David S. Miller2007-03-194-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The manual says that it is required and we actually have crash reports where loads see stale data due to not having membars here. In one case the networking does: memset(skb, 0, offsetof(struct sk_buff, truesize)); and then some code later checks skb->nohdr for zero, but it's still the value that was there before the memset(). Note that arch/sparc64/lib/xor.S already got this right. Signed-off-by: David S. Miller <davem@davemloft.net>

| * | usblp: quirk flag and device entry for Seiko Epson M129C printerAlan Stern2007-03-191-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as872) adds a device table entry and a new quirk flag to the usblp driver for the Seiko Epson Receipt printer. This printer returns Vendor-Specific values for bInterfaceClass and bInterfaceSubClass, but the bInterfaceProtocol value is valid and it works with usblp. The new quirks flag tells the driver to ignore the Class and SubClass values in the interface descriptor.

| * | airprime: USB ID for Novatel EV620 mini PCI-E cardMark Glines2007-03-191-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add an ID to recognise the Novatel EV620 wireless adapter. http://www.novatelwireless.com/products/expedite/ev620.html It looks like a mini PCI-Express adapter. The mPCIE connector includes USB pins... the card shows up to the system as a USB device, and powers itself from the PCI bus. The card I have isn't activated yet, so I can't get a PPP session up yet, but I have tested basic serial communication successfully in both 2.6.18 and 2.6.20 kernels, once the product ID was added. (the driver changed quite a bit between the two revs.) In both drivers, it responds to AT commands and such.

| * | USB: necessary update for mos7720 driverOliver Neukum2007-03-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | these devices have a shared interrupt endpoint. For serialcore to pass an interrupt endpoint to a subdriver, the subdriver must define and _export_ a fitting callback. The mos7720 driver failed to do so. This led invariably to an oops upon open. This patch fixes it. The driver is useless without it. Please try to get this into 2.6.21 and the stable kernels that have this driver.

For example, when *lower_limit is 0xfd000000 and bar_size is 0x4000000, in the following code at arch/sh/drivers/pci/pci-auto.c, 0x0 is set in bar_value. pciauto_setup_bars() { ... bar_value = ((*lower_limit - 1) & ~(bar_size - 1)) + bar_size; ... *lower_limit = bar_value + bar_size; } As a result, 0x4000000 is set in *lower_limit, but this value is wrong. The following patch avoids this problem by checking the range of the value and refusing to update the BAR if the calculated value ends up being bogus.

When converting tty_io.c to store pids as struct pid pointers instead of pid_t values it appears I overlooked two places where we stop using the pid value. The very obvious one is in do_tty_hangup, and the one the less obvious one in __proc_set_tty. When looking into the code __proc_set_tty only has pids that need to be put because of failures of other parts of the code to properly perform hangup processing. Fixing the leak here in __proc_set_tty is easy and obviously correct so I am doing that first. Fixing the places that should be performing hangup processing is much less obviously correct. So those I'm aiming those patches at -mm. for now, so the can age a while before they are merged. Signed-off-by: Eric W.

* | | [PATCH] i386: trust the PM-Timer calibration of the local APIC timerThomas Gleixner2007-03-181-51/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When PM-Timer is available for local APIC timer calibration we can skip the verification of the calibrated time value. The resulting error is quite small on a bunch of evaluated platforms and is less harming than the observed false positives. We need to keep the verification on systems, which have no PM-Timer to avoid bogus local APIC timer calibrations in the range of factor 2-10, which can be observed when swicthing off the PM-timer support in the kernel configuration. The wrong calibration values are probably caused by SMM code trying to emulate a PS/2 keyboard from a (maybe connected or not) USB keyboard. This prohibits the accurate delivery of PIT interrupts, which are used to calibrate the local APIC timer. Unfortunately we have no way to disable this BIOS misfeature in the early boot process. Add also the dropped cpu_relax() back to the wait loops.
