The sysfs files in arcmsr are non-standard in that they aren't simple filename value pairs, the values actually contain preceeding text which would have to be parsed. The idea of sysfs files is that the file name is the description and the contents is a simple value. Fix up arcmsr to conform to this standard.

Remove sysfs_remove_bin_file() return-value checking from the areca driver. There's nothing a driver can do if sysfs file removal fails, so we'll soon be changing sysfs_remove_bin_file() to internally print a diagnostic and to return void.

The Bluetooth L2CAP layer has 2 locks that are used in softirq context, (one spinlock and one rwlock, where the softirq usage is readlock) but where not all usages of the lock were _bh safe.

There exists no attempt do deal with the fact that a structure with a uint32_t followed by a pointer is going to be different for 32-bit and 64-bit userspace.

This patch lets BT_HIDP depend on instead of select INPUT. This fixes the following warning during an s390 build: net/bluetooth/hidp/Kconfig:4:warning: 'select' used by config symbol 'BT_HIDP' refer to undefined symbol 'INPUT' A dependency on INPUT also implies !S390 (and therefore makes the explicit dependency obsolete) since INPUT is not available on s390. The practical difference should be nearly zero, since INPUT is always set to y unless EMBEDDED=y (or S390=y). Signed-off-by: Adrian Bunk <bunk@stusta.de>

Ramiro Voicu hits the BUG_ON(!pte_none(*pte)) in zeromap_pte_range: kernel bugzilla 7645. Right: read_zero_pagealigned uses down_read of mmap_sem, but another thread's racing read of /dev/zero, or a normal fault, can easily set that pte again, in between zap_page_range and zeromap_page_range getting there. It's been wrong ever since 2.4.3. The simple fix is to use down_write instead, but that would serialize reads of /dev/zero more than at present: perhaps some app would be badly affected. So instead let zeromap_page_range return the error instead of BUG_ON, and read_zero_pagealigned break to the slower clear_user loop in that case - there's no need to optimize for it. Use -EEXIST for when a pte is found: BUG_ON in mmap_zero (the other user of zeromap_page_range), though it really isn't interesting there. And since mmap_zero wants -EAGAIN for out-of-memory, the zeromaps better return that than -ENOMEM. Signed-off-by: Hugh Dickins <hugh@veritas.com> Signed-off-by: Adrian Bunk <bunk@stusta.de>

When the old IDE layer calls into methods in the driver during error handling it is essentially random whether ide_lock is already held. This causes a deadlock in the atiixp driver which also uses ide_lock internally for locking. Switch to a private lock instead.

It's a known fact that Windows times out commands after 7 seconds, so drives generally try and respond if they can before that happens. We default to 5 seconds, which sometimes is a bit too short. Jeremy Higdon reported here: http://lkml.org/lkml/2007/1/1/145 that his drive takes longer than 5 seconds for a "read track information" command, later confirming that it is about 6.7 seconds. So just do the sane thing and change the default command timeout to 7 seconds to avoid other surprises. Signed-off-by: Jens Axboe <jens.axboe@oracle.com> Signed-off-by: Adrian Bunk <bunk@stusta.de>

Original patch from Ian Dall in bugzilla. Set command timeout as specified by the SCSI layer rather than hardcode it to 30 seconds. I have received a couple of reports of people hitting this one with various tape configurations and the patch looks obviously correct. From http://bugzilla.kernel.org/show_bug.cgi?id=6275 Ian Dall <ian@beware.dropbear.id.au>: The command sent to the card was using a 30second timeout regardless of the timeout requested in the scsi command passed down from higher levels.

The whole idea with the NOTRACK netfilter target is that you can force the netfilter code to avoid connection tracking, and all costs assosciated with it, by making traffic match a NOTRACK rule. But this is totally broken by the fact that we do a checksum calculation over the packet before we do the NOTRACK bypass check, which is very expensive. People setup NOTRACK rules explicitly to avoid all of these kinds of costs. This patch from Patrick, already in Linus's tree, fixes the bug. Move the check for ip_conntrack_untracked before the call to skb_checksum_help to fix NOTRACK excemptions from NAT. Pre-2.6.19 NAT code breaks TSO by invalidating hardware checksums for every packet, even if explicitly excluded from NAT through NOTRACK. 2.6.19 includes a fix that makes NAT and TSO live in harmony, but the performance degradation caused by this deserves making at least the workaround work properly in -stable.
