2007-11-27mmc: Add missing sg_init_table() callHaavard Skinnemoen

2007-11-27blktrace: Make sure BLKTRACETEARDOWN does the full cleanup.Aneesh Kumar K.V
if blktrace program segfault it will not be able to call BLKTRACETEARDOWN. Now if we run the blktrace again that would result in a failure to create the block/<device> debugfs directory.This will result in blk_remove_root() to be called which will set blk_tree_root to NULL. But the debugfs block dir still exist because it contain subdirectory. Now if we try to fix it using BLKTRACETEARDOWN it won't work because blk_tree_root is NULL. Fix the same. Tested as below root@qemu-image:/home/kvaneesh/blktrace# ./blktrace -d /dev/hdc Segmentation fault root@qemu-image:/home/kvaneesh/blktrace# ./blktrace -d /dev/hdc BLKTRACESETUP: No such file or directory Failed to start trace on /dev/hdc root@qemu-image:/home/kvaneesh/blktrace# ./blktrace -k /dev/hdc root@qemu-image:/home/kvaneesh/blktrace# ./blktrace -d /dev/hdc Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

2007-11-26plip: fix parport_register_device name parameterMikulas Patocka
Plip passes a string "name" that is allocated on stack to parport_register_device. parport_register_device holds the pointer to "name" and when the registering function exits, it points nowhere. On some machine, this bug causes bad names to appear in /proc, such as /proc/sys/dev/parport/parport0/devices/T^/�X^/�, on others, the plip proc node is completely missing. The patch also fixes documentation to note this requirement. Signed-off-by: Mikulas Patocka <mikulas@artax.karlin.mff.cuni.cz> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-11-26plip: use netif_rx_ni() for packet receiveMikulas Patocka
netif_rx is meant to be called from interrupts because it doesn't wake up ksoftirqd. For calling from outside interrupts, netif_rx_ni exists. This fixes plip to use netif_rx_ni. It fixes the infamous error "NOHZ: local_softirq_panding 08" that happens on some machines with NOHZ and plip --- it is caused by the fact that softirq is pending and ksoftirqd is sleeping.

2007-11-27[XFRM]: Fix leak of expired xfrm_statesPatrick McHardy
The xfrm_timer calls __xfrm_state_delete, which drops the final reference manually without triggering destruction of the state. Change it to use xfrm_state_put to add the state to the gc list when we're dropping the last reference. The timer function may still continue to use the state safely since the final destruction does a del_timer_sync().

2007-11-26x86: correctly set UTS_MACHINE for "make ARCH=x86"Andreas Herrmann
For a kernel built with "make ARCH=x86" the following system information is displayed when running the new kernel $ uname -m x86 On some i386 systems (e.g. K7) we even have the following information $ uname -m x66 This is weird. The usual information for "uname -m" should be "x86_64" on 64-bit and "i386" or "i686" on 32-bit. This patch fixes the issue by setting UTS_MACHINE to "i386" for 32-bit kernel builds and to "x86_64" for 64-bit kernel builds. I.e., "x86" won't be used for UTS_MACHINE anymore.

2007-11-26NFS: mount failure causes bad page stateRussell King
While testing a kernel based upon ecd744eec3aa8bbc949ec04ed3fbf7ecb2958a0e (with wrong boot arguments), I got the following bad page state entry while NFS was trying to mount it's rootfs: IP-Config: Complete: device=eth0, addr=192.168.1.101, mask=255.255.255.0, gw=255.255.255.255, host=192.168.1.101, domain=, nis-domain=(none), bootserver=192.168.1.100, rootserver=192.168.1.100, rootpath= Looking up port of RPC 100003/2 on 192.168.1.100 rpcbind: server 192.168.1.100 not responding, timed out Root-NFS: Unable to get nfsd port number from server, using default Looking up port of RPC 100005/1 on 192.168.1.100 rpcbind: server 192.168.1.100 not responding, timed out Root-NFS: Unable to get mountd port number from server, using default mount: server 192.168.1.100 not responding, timed out Root-NFS: Server returned error -5 while mounting /nfs/rootfs/ VFS: Unable to mount root fs via NFS, trying floppy.

This seems to be caused by use of an uninitialised structure due to NULL options being passed to nfs_validate_mount_data(). Ensure that the parsed mount data is always initialised.

2007-11-26SUNRPC: remove NFS/RDMA client's binary sysctlsJames Lentini
Support for binary sysctls is being deprecated in 2.6.24. Since there are no applications using the NFS/RDMA client's binary sysctls, it makes sense to remove them. The patch below does this while leaving the /proc/sys interface unchanged. Please consider this for 2.6.24.

Srivatsa Vaddagiri noticed occasionally incorrect CPU usage values in top and tracked it down to stime going below 0 in task_stime(). Negative values are possible there due to the sampled nature of stime/utime. Fix suggested by Balbir Singh.

2007-11-26x86: fix APIC related bootup crash on Athlon XP CPUsIngo Molnar
warmbloodedcreature@gmail.com reported that an APIC-enabled Asus a7v8x-x with an Athlon XP reboots early in the bootup: http://bugzilla.kernel.org/show_bug.cgi?id=8723 after a long marathon of spontaneous-reboot debugging, it turns out to be caused by sync_Arb_ids(). AMD CPUs never really needed this sequence anyway, so just return early if we meet an AMD CPU. Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
