2007-11-27ide: add CONFIG_IDE_H8300 config optionBartlomiej Zolnierkiewicz
Add a separate config option for ide-8300 host driver instead of depending on CONFIG_H8300. This change is a preparation for the future changes and also allows ide-h8300 to be disabled if needed.

2007-11-27aec62xx: Fix kernel oops in driver's probe functionAleksandar Radovanovic
Add pci_enable_device() to aec62xx probe function before doing any I/O. Original probe function tries to read from device's PCI region 4 before calling ide_setup_pci_device(). Since the device is not enabled at this point, on machines that have no firmware PCI initialization (e.g. ASUS WL-700gE router), corresponding PCI BAR is 0 and the following inb() causes a kernel oops.

2007-11-27ide: skip ide_wait_not_busy() on noprobe-disksJonas Stare
There is a problem in some hardware where the kernel will stall for 35 seconds waiting for disks that don't exist. This patch will skip waiting for the BSY-bit on IDE drives to go away if you set "hdx=noprobe" as a kernel option and the disk is not marked as 'present' (like when you set the geometry by hand). If no noprobe-option is set the code will work (more or less) as the original but if set the code will skip the ide_wait_not_busy() for that drive. Even if there would be a drive there and it is still busy afterwards it should not matter since it isn't probed for later. The code also honors the MAX_DRIVES variable instead of assuming that there will be two harddrives on the bus.

2007-11-27siimage: remove resetproc() methodSergei Shtylyov
The intent behind siimage_reset() was probably to hard reset the interface and the SATA PHY but as the code writes to two reserved bits instead, it obviously has been ineffective from the start. So, just remove it. Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.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.
