From: Olaf Kirch <okir@suse.de> I have been chasing a corruption of current->group_info on PPC during NFS stress tests. The problem seems to be that nfsd is messing with its group_info quite a bit, while some monitoring processes look at /proc/<pid>/status and do a get_group_info/put_group_info without any locking. This problem can be reproduced on ppc platforms within a few seconds if you generate some NFS load and do a "cat /proc/XXX/status" of an nfsd thread in a tight loop. I therefore think changes to current->group_info, and querying it from a different process, needs to be protected using the task_lock. (akpm: task->group_info here is safe against exit() because the task holds a ref on group_info which is released in __put_task_struct, and the /proc file has a ref on the task_struct).

ep_send_events() uses ~350 bytes of stack for a local buffer of events to send to userspace. The patch fixes that by removing the double-buffering altogether. A pipe-based microbenchmark from Davide Libenzi <davidel@xmailserver.org> was sped up by 1-2%.

From: Ingo Molnar <mingo@elte.hu> printk currently does if (oops_in_progres) bust_printk_locks(); which means that once we oops, the printk locking is 100% ineffective and multiple CPUs make an unreadable mess on a serial console. It's a significant development hassle. Fix that up by only popping locks once per ten seconds. akpm@osdl.org did: - Bump the timeout to 30 seconds - 9600 baud is slow. - Handle jiffy wraps: change the logic so that we only skip the lockbust if the current time is within 30 seconds of the previous lockbusting attempt.

From: "J. Bruce Fields" <bfields@fieldses.org> The kernel currently prints: nfsd: nobody listening for auth.unix.ip upcall; has some daemon not been started? on every bootup, during initscripts. Neil Brown <neilb@cse.unsw.edu.au> says: It was part of the recent set of idmapper patches. Bruce wanted the admin to get a warning when the idmapper daemon wasn't running. I thought the same warning should apply to any daemon that responded to upcalls. In the case of auth.unix.ip it isn't strictly necessary for a daemon to be running (for comparability with 2.4). You can get rid of the warning by doing: mount -t nfsd nfsd /proc/fs/nfs before mountd is started (init scripts should start doing this I hope, but distributions don't tend to use the init script from nfs-utils, so it is hard to push it). This will trigger mountd to listen on auth.unix.ip and others. That's a hassle, so Bruce's patch limits the warning purely to the new idmapper cache. It provides a callback in the cache_detail that individual caches can use to log messages when upcalls fail because a userspace daemon not running. Implement this method for the idmapping caches.

Signed-off-by: Paul Mackerras <paulus@samba.org> Early in the boot process on pSeries machines, we look in the Open Firmware device tree for information about the interrupt assignments, and assign virtual IRQ numbers for each physical IRQ. There is currently a couple of bugs in this code which result in us assigning virtual IRQs for nonexistent physical IRQs. This causes problems when we call the firmware to enable or disable those nonexistent physical IRQs. Some versions at least of the firmware will hit an assertion failure and crash the machine when this happens. This patch fixes the bugs and ensures that we don't try and use nonexistent physical IRQ numbers. One bug was that we were mapping ISA interrupts, which is unnecessary since virtual IRQ numbers 0 - 15 are reserved for them. The other was that when we had a PCI interrupt (which is always in the range 1 to 4, corresponding to INTA to INTD) which didn't have a mapping in the PCI host bridge above it, we were just using the original number (usually 1) rather than ignoring it.

Signed-off-by: Anton Blanchard <anton@samba.org> We have cards that want over 2MB of PCI consistent memory. The IOMAP_MAX_ORDER limit is just to catch bad drivers early, so we can bump this a bit. We want some room to grow but our maximum get_free_pages allocation on ppc64 is currently 16MB, so it doesnt make sense to go above that.

From: Stephen Rothwell <sfr@canb.auug.org.au> This patch allows us to dynamically add virtual disks to an iSeries partition. It works like this: after you have created the virtual disk file on OS/400 and attached it to the Linux partition, you need to write to /sys/bus/vio/drivers/viodasd/probe (it doesn't matter what you write). This will do the probe. It calls add_disk() for each new disk, so we get hotplug events as a side effect. This was the nicest way I could think of doing this as the interface to the hypervisor is polled ...

From: Anton Blanchard <anton@samba.org> From: Anton Blanchard, Dave Hansen and Olof Johansson: Fix multiple bugs in the ppc64 NUMA topology probe code. - We were using HW cpu numbers instead of logical ones. 615, 630, 650, some 670 and some 690 SMP will all fail to boot without this patch. - The old code would BUG() when it got confused (more NUMA zones than the kernel is configured for etc). - The common depth calculation was incorrect. Dave found an OF property that gives us exactly what we want. - Things were broken on SMT machines. The new code should work on those broken systems and should no longer BUG() but fall back to a flat topology when it gets confused.

From: Zdenek Pavlas <pavlas@nextra.cz> On any x86 without cpuid, early_cpu_detect() left x86_cache_alignment as zero, so kmem_cache_init() calls cache_estimate() with align == 0, and it loops forever. I've tried this trivial fix, and it works for me. Andi Kleen looked over this, and ok'd it.

This improves the stack traces we get on PPC64 by putting a marker in those stack frames that are created as a result of an interrupt or exception. The marker is "regshere" (0x7265677368657265). With this, stack traces show where exceptions have occurred, which can be very useful. This also improves the accuracy of the trace because the relevant return address can be in the link register at the time of the exception rather than on the stack. We now print the PC and exception type for each exception frame, and then the link register if appropriate as the next item in the trace.

Disabling IRQs over context switches causes unreasonable IRQ latency on VIVT cached machines, so provide our own prepare_arch_switch(), finish_arch_switch() and task_running() implementations. We provide an optimised UP version so we don't end up needlessly incrementing and decrementing the preempt count.

Any architecture (like pa-risc) that makes use of the helper function flush_dcache_mmap_lock() won't compile with the new rmap due to use of the wrong "mapping". Trivial fix.
