Since we now use the generic backlight infrastructure, I think we need to call rivafb_bl_init before calling register_framebuffer since otherwise rivafb_bl_init might race with the framebuffer layer already opening the device and setting up the video mode. In this case we might end up with a not yet fully intialized backlight (info->bl_dev still NULL) when calling riva_bl_set_power via rivafb_set_par/rivafb_load_video_mode and the kernel dies without any further notice during boot. This fixes booting current git on a PB 6,1. In this case radeonfb/atyfb would be affected too - I can fix that too but don't have any hardware to test this on. Cc: "Antonino A.

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.

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.

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. Signed-off-by:

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. Signed-off-by:

Commit 7b2fd697427e73c81d5fa659efd91bd07d303b0e in the historical GIT tree stopped calling the readdir member of a file_operations struct with the big kernel lock held, and fixed up all the readdir functions to do their own locking.

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". Signed-off-by:

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.

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=de30a2b3 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. Signed-off-by:
