* [PATCH] powermac: More powermac backlight fixesMichael Hanselmann2006-07-31
| | | | | | | | | | | | | | | | | This patch fixes several problems: - The legacy backlight value might be set at interrupt time. Introduced a worker to prevent it from directly calling the backlight code. - via-pmu allows the backlight to be grabbed, in which case we need to prevent other kernel code from changing the brightness. - Don't send PMU requests in via-pmu-backlight when the machine is about to sleep or waking up. - More Kconfig fixes.

* [PATCH] radeonfb sleep fixesVolker Braun2006-07-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | Many IBM Thinkpad T4* models and some R* and X* with radeon video cards draw too much power when suspended to RAM, reducing drastically the battery lifetime. The solution is to enable suspend-to-D2 on these machines. They are whitelisted through their subsystem vendor/device ID. This fixes http://bugzilla.kernel.org/show_bug.cgi?id=3022 The patch introduces a framework to alter the pm_mode and reinit_func fields of the radeonfb_info structure based on a whitelist. This should facilitate future hardware-dependent workarounds. The workaround for the Samsung P35 that is already in the radeonfb code has been rewritten using this framework. The behavior can be overridden with module options: i) video=radeonfb:force_sleep=1 enable suspend-to-D2 also on non-whitelisted machines (useful for testing new notebook models), ii) video=radeonfb:ignore_devlist=1 Disable checking the whitelist and do not apply any workarounds.

* [PATCH] fbdev: statically link the framebuffer notification functionsAntonino A. Daplas2006-07-31
| | | | | | | | | | | | | | | The backlight and lcd subsystems can be notified by the framebuffer layer of blanking events. However, these subsystems, as a whole, can function independently from the framebuffer layer. But in order to enable to the lcd and backlight subsystems, the framebuffer has to be compiled also, effectively sucking in a huge amount of unneeded code. To prevent dependency problems, separate out the framebuffer notification mechanism from the framebuffer layer and permanently link it to the kernel.

* [PATCH] 9p: fix fid behavior on failed removeEric Van Hensbergen2006-07-31
| | | | | | | | | | | | | | | | | Based on a bug report from Russ Ross <russruss@gmail.com> According to the spec: "The remove request asks the file server both to remove the file represented by fid and to clunk the fid, even if the remove fails." but the Linux client seems to expect the fid to be valid after a failed remove attempt. Specifically, I'm getting this behavior when attempting to remove a non-empty directory.

* [PATCH] fuse: use jiffies_64Miklos Szeredi2006-07-31
| | | | | | | | | | | | | | | | | | It is entirely possible (though rare) that jiffies half-wraps around, while a dentry/inode remains in the cache. This could mean that the dentry/inode is not invalidated for another half wraparound-time. To get around this problem, use 64-bit jiffies. The only problem with this is that dentry->d_time is 32 bits on 32-bit archs. So use d_fsdata as the high 32 bits. This is an ugly hack, but far simpler, than having to allocate private data just for this purpose. Since 64-bit jiffies can be assumed never to wrap around, simple comparison can be used, and a zero time value can represent "invalid".

* [PATCH] vDSO hash-style fixRoland McGrath2006-07-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The latest toolchains can produce a new ELF section in DSOs and dynamically-linked executables. The new section ".gnu.hash" replaces ".hash", and allows for more efficient runtime symbol lookups by the dynamic linker. The new ld option --hash-style={sysv|gnu|both} controls whether to produce the old ".hash", the new ".gnu.hash", or both. In some new systems such as Fedora Core 6, gcc by default passes --hash-style=gnu to the linker, so that a standard invocation of "gcc -shared" results in producing a DSO with only ".gnu.hash". The new ".gnu.hash" sections need to be dealt with the same way as ".hash" sections in all respects; only the dynamic linker cares about their contents. To work with older dynamic linkers (i.e. preexisting releases of glibc), a binary must have the old ".hash" section. The --hash-style=both option produces binaries that a new dynamic linker can use more efficiently, but an old dynamic linker can still handle. The new section runs afoul of the custom linker scripts used to build vDSO images for the kernel. On ia64, the failure mode for this is a boot-time panic because the vDSO's PT_IA_64_UNWIND segment winds up ill-formed. This patch addresses the problem in two ways. First, it mentions ".gnu.hash" in all the linker scripts alongside ".hash". This produces correct vDSO images with --hash-style=sysv (or old tools), with --hash-style=gnu, or with --hash-style=both. Second, it passes the --hash-style=sysv option when building the vDSO images, so that ".gnu.hash" is not actually produced. This is the most conservative choice for compatibility with any old userland. There is some concern that some ancient glibc builds (though not any known old production system) might choke on --hash-style=both binaries. The optimizations provided by the new style of hash section do not really matter for a DSO with a tiny number of symbols, as the vDSO has. If someone wants to use =gnu or =both for their vDSO builds and worry less about that compatibility, just change the option and the linker script changes will make any choice work fine.

* [PATCH] Reducing local_bh_enable/disable overhead in irqtraceTim Chen2006-07-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recent changes from irqtrace feature has added overheads to local_bh_disable and local_bh_enable that reduces UDP performance across x86_64 and IA64, even though IA64 does not support the irqtrace feature. Patch in question is [PATCH]lockdep: irqtrace subsystem, core http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=c ommit;h=de30a2b355ea85350ca2f58f3b9bf4e5bc007986 Prior to this patch, local_bh_disable was a short macro. Now it is a function which calls __local_bh_disable with added irq flags save and restore. The irq flags save and restore were also added to local_bh_enable, probably for injecting the trace irqs code. This overhead is on the generic code path across all architectures. On a IA_64 test machine (Itanium-2 1.6 GHz) running a benchmark like netperf's UDP streaming test, the added overhead results in a drop of 3% in throughput, as udp_sendmsg calls the local_bh_enable/disable several times. Other workloads that have heavy usages of local_bh_enable/disable could also be affected. The patch ideally should not have affected IA-64 performance as it does not have IRQ tracing support. A significant portion of the overhead is in the added irq flags save and restore, which I think is not needed if IRQ tracing is unused. A suggested patch is attached below that recovers the lost performance. However, the "ifdef"s in the patch are a bit ugly.

* [PATCH] Fix swsusp with PNP BIOSOndrej Zary2006-07-31
| | | | | | | | | | | | | | | | | | | | | swsusp is unable to suspend my machine (DTK FortisPro TOP-5A notebook) with kernel 2.6.17.5 because it's unable to suspend PNP device 00:16 (mouse). The problem is in PNP BIOS. pnp_bus_suspend() calls pnp_stop_dev() for the device if the device can be disabled according to pnp_can_disable(). The problem is that pnpbios_disable_resources() returns -EPERM if the device is not dynamic (!pnpbios_is_dynamic()) but insert_device() happily sets PNP_DISABLE capability/flag even if the device is not dynamic. So we try to disable non-dynamic devices which will fail. This patch prevents insert_device() from setting PNP_DISABLE if the device is not dynamic and fixes suspend on my system.

And voila, there is an AB, a BC, a CD relationship (even a direct BCD), and also now a DA relationship -> a circular type AB-BA deadlock but involving 4 locks. The solution is simple: kernel_event() is NOT allowed to use GFP_KERNEL, but must use GFP_NOFS to not cause recursion into the VFS.

| | | | | | | | | | | | | | kernel/workqueue.c was omitted from generating kernel documentation. This adds a new section "Workqueues and Kevents" and adds documentation for some of the functions.

* [PATCH] fix cond_resched() fixJim Houston2006-07-31
| | | | | | | | | | | | | | In cond_resched_lock() it calls __resched_legal() before dropping the spin lock. __resched_legal() will always finds the preempt_count non-zero and will prevent the call to __cond_resched(). The attached patch adds a parameter to __resched_legal() with the expected preempt_count value.

* [PATCH] fix bad macro param in timer.cSteven Rostedt2006-07-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have #define INDEX(N) (base->timer_jiffies >> (TVR_BITS + N * TVN_BITS)) & TVN_MASK and it's used via list = varray[i + 1]->vec + (INDEX(i + 1)); So, due to underparenthesisation, this INDEX(i+1) is now a ... (TVR_BITS + i + 1 * TVN_BITS)) ... So this bugfix changes behaviour. It worked before by sheer luck: "If i was anything but 0, it was broken. But this was only used by s390 and arm. Since it was for the next interrupt, could that next interrupt be a problem (going into the second cascade)? But it was probably seldom wrong. That is, this would fail if the next interrupt was in the second cascade, and was wrapped. Which may never of happened. Also if it did happen, it would have just missed the interrupt. If an interrupt was missed, and no one was there to miss it, was it really missed :-)" Signed-off-by: Steven Rostedt <rostedt@goodmis.org> Cc: Oleg Nesterov <oleg@tv-sign.ru> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] cpu hotplug: replace __devinit* with __cpuinit* for cpu notificationsChandra Seetharaman2006-07-31
| | | | | | | | | | | | | | | | Few of the callback functions and notifier blocks that are associated with cpu notifications incorrectly have __devinit and __devinitdata. They should be __cpuinit and __cpuinitdata instead. It makes no functional difference but wastes text area when CONFIG_HOTPLUG is enabled and CONFIG_HOTPLUG_CPU is not. This patch fixes all those instances.

* [PATCH] panic_on_oops: remove ssleep()Horms2006-07-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is part of an effort to unify the panic_on_oops behaviour across all architectures that implement it. It was pointed out to me by Andi Kleen that if an oops has occured in interrupt context, then calling sleep() in the oops path will only cause a panic, and that it would be really better for it not to be in the path at all. This patch removes the ssleep() call and reworks the console message accordinly. I have a slght concern that the resulting console message is too long, feedback welcome. For powerpc it also unifies the 32bit and 64bit behaviour. Fror x86_64, this patch only updates the console message, as ssleep() is already not present.
