2008-09-09MX2: Add DMA support for mx2 and (eventually) mx1Sascha Hauer
This patch adds DMA support for Freescale i.MX27 SoCs. It is derived from the i.MX1 port and should (though currently untested) still be working for the i.MX1. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2008-09-09i.MX: Add FIQ supportPaulius Zaleckas
Drivers which are going to use it will have to select it and use imx_set_irq_fiq() to set FIQ mode for this interrupt. Changes since V1: - removed '#ifdef CONFIG_FIQ' from irqs.h - renamed imx_set_irq_type() to imx_set_irq_fiq() - made irqt unsigned - fixed irq number check Signed-off-by: Paulius Zaleckas <paulius.zaleckas@teltonika.lt> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

2008-09-08NFS: Restore missing hunk in NFS mount option parserChuck Lever
Automounter maps can contain mount options valid for other NFS implementations but not for Linux. The Linux automounter uses the mount command's "-s" command line option ("s" for "sloppy") so that mount requests containing such options are not rejected. Commit f45663ce5fb30f76a3414ab3ac69f4dd320e760a attempted to address a known regression with text-based NFS mount option parsing. Unrecognized mount options would cause mount requests to fail, even if the "-s" option was used on the mount command line. Unfortunately, this commit was not complete as submitted. It adds a new mount option, "sloppy". But it is missing a hunk, so it now allows NFS mounts with unrecognized mount options, even if the "sloppy" option is not present. This could be a problem if a required critical mount option such as "sync" is misspelled, for example, and is considered a regression from 2.6.26. This patch restores the missing hunk. Now, the default behavior of text-based NFS mount options is as before: any unrecognized mount option will cause the mount to fail. Please include this in 2.6.27-rc. Thanks to Neil Brown for reporting this. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Acked-by: J.

2008-09-08bridge: don't allow setting hello time to zeroStephen Hemminger
Dushan Tcholich reports that on his system ksoftirqd can consume between %6 to %10 of cpu time, and cause ~200 context switches per second. He then correlated this with a report by bdupree@techfinesse.com: http://marc.info/?l=linux-kernel&m=119613299024398&w=2 and the culprit cause seems to be starting the bridge interface. In particular, when starting the bridge interface, his scripts are specifying a hello timer interval of "0". The bridge hello time can't be safely set to values less than 1 second, otherwise it is possible to end up with a runaway timer.

The timewait sockets life cycle is not tied with the network namespace, that means the timewait sockets stay alive while the network namespace dies. The timewait sockets are for avoiding to receive a duplicate packet from the network, if the network namespace is freed, the network stack is removed, so no chance to receive any packets from the outside world. Furthermore, having a pending destruction timer on these sockets with a network namespace freed is not safe and will lead to an oops if the timer callback which try to access data belonging to the namespace like for example in: inet_twdr_do_twkill_work -> NET_INC_STATS_BH(twsk_net(tw), LINUX_MIB_TIMEWAITED); Purging the timewait sockets at the network namespace destruction will: 1) speed up memory freeing for the namespace 2) fix kernel panic on asynchronous timewait destruction Signed-off-by: Daniel Lezcano <dlezcano@fr.ibm.com> Acked-by: Denis V.

2008-09-08libata-sff: kill spurious WARN_ON() in ata_hsm_move()Tejun Heo
On HSM_ST_ERR, ata_hsm_move() triggers WARN_ON() if AC_ERR_DEV or AC_ERR_HSM is not set. PHY events may trigger HSM_ST_ERR with other error codes and, with or without it, there just isn't much reason to do WARN_ON() on it. Even if error code is not set there, core EH logic won't have any problem dealing with the error condition. OSDL bz#11065 reports this problem.

2008-09-08sata_nv: disable hardreset for genericTejun Heo
of them being unifying probing, hotplug and EH reset paths uniform. Previously, broken hardreset could go unnoticed as it wasn't used during probing but when something goes wrong or after hotplug the problem will surface and bite hard. OSDL bug 11195 reports that sata_nv generic flavor falls into this category. Hardreset itself succeeds but PHY stays offline after hardreset. I tried longer debounce timing but the result was the same. http://bugzilla.kernel.org/show_bug.cgi?id=11195 So, it seems we'll have to drop hardreset from the generic flavor.

2008-09-08ahci, pata_marvell: play nicely togetherAlan Cox
I've been chasing Jeff about this for months. Jeff added the Marvell device identifiers to the ahci driver without making the AHCI driver handle the PATA port. This means a lot of users can't use current kernels and in most distro cases can't even install. This has been going on since March 2008 for the 6121 Marvell, and late 2007 for the 6145!!! This was all pointed out at the time and repeatedly ignored. Bugs assigned to Jeff about this are ignored also. To quote Jeff in email > "Just switch the order of 'ahci' and 'pata_marvell' in > /etc/modprobe.conf, then use Fedora's tools regenerate the initrd. > See? It's not rocket science, and the current configuration can be > easily made to work for Fedora users." (Which isn't trivial, isn't end user, shouldn't be needed, and as it usually breaks at install time is in fact impossible) To quote Jeff in August 2007 > " mv-ahci-pata > Marvell 6121/6141 PATA support. Needs fixing in the 'PATA controller > command' area before it is usable, and can go upstream." Only he add the ids anyway later and caused regressions, adding a further id in March causing more regresions. The actual fix for the moment is very simple. If the user has included the pata_marvell driver let it drive the ports. If they've only selected for SATA support give them the AHCI driver which will run the port a fraction faster. Allow the user to control this decision via ahci.marvell_enable as a module parameter so that distributions can ship 'it works' defaults and smarter users (or config tools) can then flip it over it desired.

We currently have a race when scheduling a context to a SPE - after we have found a runnable context in spusched_tick, the same context may have been scheduled by spu_activate(). This may result in a panic if we try to unschedule a context that has been freed in the meantime. This change exits spu_schedule() if the context has already been scheduled, so we don't end up scheduling it twice.

2008-09-06x86: cpu_init(): fix memory leak when using CPU hotplugAndreas Herrmann
Exception stacks are allocated each time a CPU is set online. But the allocated space is never freed. Thus with one CPU hotplug offline/online cycle there is a memory leak of 24K (6 pages) for a CPU. Fix is to allocate exception stacks only once -- when the CPU is set online for the first time.

2008-09-06x86: pda_init(): fix memory leak when using CPU hotplugAndreas Herrmann
pda->irqstackptr is allocated whenever a CPU is set online. But it is never freed. This results in a memory leak of 16K for each CPU offline/online cycle. Fix is to allocate pda->irqstackptr only once. Signed-off-by: Andreas Herrmann <andreas.herrmann3@amd.com> Cc: akpm@linux-foundation.org Signed-off-by: Ingo Molnar <mingo@elte.hu>
