* mac80211: Replace ieee80211_tx_control->key_idx with ieee80211_key_confIvo van Doorn2008-05-078-18/+30
| | | | | | | | | | | | | | | | | | | | | | | | The hw_key_idx inside the ieee80211_key_conf structure does not provide all the information drivers might need to perform hardware encryption. This is in particular true for rt2x00 who needs to know the key algorithm and whether it is a shared or pairwise key. By passing the ieee80211_key_conf pointer it assures us that drivers can make full use of all information that it should know about a particular key. Additionally this patch updates all drivers to grab the hw_key_idx from the ieee80211_key_conf structure. v2: Removed bogus u16 cast v3: Add warning about ieee80211_tx_control pointers v4: Update warning about ieee80211_tx_control pointers Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Acked-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

* tipc: Elimination of print buffer chainingAllan Stephens2008-05-053-94/+80
| | | | | | | | | | | | | | This patch revamps TIPC's print buffer subsystem to eliminate support for arbitrary chains of print buffers, which were rarely needed and difficult to use safely. In its place, print buffers can now be configured to echo their output to the system console. This provides an equivalent for the only chaining currently utilized by TIPC, in a faster and more compact manner. Signed-off-by: Allan Stephens <allan.stephens@windriver.com> Signed-off-by: David S.

A patch for some versions of the OptiPlex was proposed here -- http://lkml.org/lkml/2007/6/5/59 -- and is included in 2.6.23 and later kernels, according to http://lxr.linux.no/linux+v2.6.23/arch/i386/kernel/reboot.c . However, the DMI_BOARD_NAME ("0WF810") is too restrictive. Newer OptiPlex machines have a DMI_BOARD_NAME of "0RF703". I therefore suggest adding another clause to reboot.c, similar to the one in the original patch, but matching a DMI_BOARD_NAME of "0RF703". On further inspection, it seems that there are other DMI_BOARD_NAMEs for this same machine. They seem to change from time to time, which means that the current code is fragile. Moreover, using bios reboot should not break non-SFF OptiPlex 745s, and so a reasonable fix is to simply drop the match on DMI_BOARD_NAME.

In particular, for i2c module aliases, the trailing wildcard is not only unneeded, it could also cause the wrong driver to be loaded. As I2C devices have no IDs, i2c module aliases are simple, arbitrary device names. For example: $ /sbin/modinfo lm90 filename: /lib/modules/2.6.25-git18/kernel/drivers/hwmon/lm90.ko author: Jean Delvare <khali@linux-fr.org> description: LM90/ADM1032 driver license: GPL vermagic: 2.6.25-git18 mod_unload depends: hwmon alias: i2c:lm90* alias: i2c:adm1032* alias: i2c:lm99* alias: i2c:lm86* alias: i2c:max6657* alias: i2c:adt7461* alias: i2c:max6680* $ This would cause trouble if one I2C chip name matches the beginning of another I2C chip name and both chips are supported by different drivers. For example, an i2c device named lm9042 would cause the lm90 driver to be loaded, while it doesn't support that device. This case has yet to be seen in practice, but still, I'd like to fix it now. The cleanest fix is to remove the trailing wildcard from i2c module aliases. Here's a patch doing this. Not all device type aliases need a trailing wildcard, in particular the i2c aliases don't. Don't add a wildcard by default in do_table(), instead let each device type handler add it if needed. I have tested types acpi, dmi, eisa, i2c, ide, ieee1394, input, pci, pcmcia, platform, pnp, scsi, serio, ssb and usb. Other types (ccw, of, vio, parisc, sdio and virtio) are untested.

| | | | | | | | | | | | | | | | | | | | | | | | | | | nonpae guests can call rmap_write_protect twice per page (for page tables) or four times per page (for page directories), triggering a bogus warning. Remove the warning. Signed-off-by: Avi Kivity <avi@qumranet.com>
| * | KVM: avoid fx_init() schedule in atomicAndrea Arcangeli2008-05-042-2/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This make sure not to schedule in atomic during fx_init. I also changed the name of fpu_init to fx_finit to avoid duplicating the name with fpu_init that is already used in the kernel, this makes grep simpler if nothing else.

| * | KVM: PIT: support mode 4Marcelo Tosatti2008-05-041-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The in-kernel PIT emulation ignores pending timers if operating under mode 4, which for example DragonFlyBSD uses (and Plan9 too, apparently). Mode 4 seems to be similar to one-shot mode, other than the fact that it starts counting after the next CLK pulse once programmed, while mode 1 starts counting immediately, so add a FIXME to enhance precision. Fixes sourceforge bug 1952988. Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Acked-by: Sheng Yang <sheng.yang@intel.com> Signed-off-by: Avi Kivity <avi@qumranet.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recent changes allowing memory operands with lmsw and smsw left lmsw with writeback enabled. Since lmsw has no oridinary destination operand, the dst pointer was not initialized, resulting in an oops. Close the hole by disabling writeback for lmsw.
