2005-05-01[PATCH] LifeView FlyTV Platinum FM: GPIO usagePeter Missel1-6/+6
This is take two of a patch that should have appeared two days ago, before yesterday's "remote control" patch for the same card. This patch sets unconnected GPIO to Output to keep them from floating (just good driver writing practice, being nice to the chip), and uses GPIO16 to switch TV vs. FM - this pin switches inputs onto the tuner, as well as the audio output from the tuner into the 7135 SIF input. Consequently, FM radio support is being un-commented because it's now working (sort of, see below). These two patches get the card almost fully operational; there appears to be a bug in tda8290.c remaining that puts an offset onto the tuned frequency in FM radio mode. We're investigating.

2005-05-01[PATCH] reiserfs: make resize option auto-get new device sizePaolo 'Blaisorblade' Giarrusso1-7/+14
It's trivial for the resize option to auto-get the underlying device size, while it's harder for the user. I've copied the code from jfs. Since of the different reiserfs option parser (which does not use the superior match_token used by almost every other filesystem), I've had to use the "resize=auto" and not "resize" option to specify this behaviour. Changing the option parser to the kernel one wouldn't be bad but I've no time to do this cleanup in this moment. Btw, the mount(8) man page should be updated to include this option.

2005-05-01[PATCH] Deprecate synchronize_kernel, GPL replacementPaul E. McKenney2-5/+34
The synchronize_kernel() primitive is used for quite a few different purposes: waiting for RCU readers, waiting for NMIs, waiting for interrupts, and so on. This makes RCU code harder to read, since synchronize_kernel() might or might not have matching rcu_read_lock()s. This patch creates a new synchronize_rcu() that is to be used for RCU readers and a new synchronize_sched() that is used for the rest. These two new primitives currently have the same implementation, but this is might well change with additional real-time support. Both new primitives are GPL-only, the old primitive is deprecated.

2005-05-01[PATCH] kernel/rcupdate.c: make the exports EXPORT_SYMBOL_GPLPaul E. McKenney2-3/+18
The gpl exports need to be put back. Moving them to GPL -- but in a measured manner, as I proposed on this list some months ago -- is fine. Changing these particular exports precipitously is most definitely -not- fine. Here is my earlier proposal: http://marc.theaimsgroup.com/?l=linux-kernel&m=110520930301813&w=2 See below for a patch that puts the exports back, along with an updated version of my earlier patch that starts the process of moving them to GPL. I will also be following this message with RFC patches that introduce two (EXPORT_SYMBOL_GPL) interfaces to replace synchronize_kernel(), which then becomes deprecated.

2005-05-01[PATCH] procfs: Fix hardlink counts for /proc/<PID>/taskDaniel Drake1-2/+6
The current logic assumes that a /proc/<PID>/task directory should have a hardlink count of 3, probably counting ".", "..", and a directory for a single child task. It's fairly obvious that this doesn't work out correctly when a PID has more than one child task, which is quite often the case.

2005-05-01[PATCH] procfs: Fix hardlink countsDaniel Drake1-2/+10
The pid directories in /proc/ currently return the wrong hardlink count - 3, when there are actually 4 : ".", "..", "fd", and "task". This is easy to notice using find(1): cd /proc/<pid> find In the output, you'll see a message similar to: find: WARNING: Hard link count is wrong for .: this may be a bug in your filesystem driver. Automatically turning on find's -noleaf option. Earlier results may have failed to include directories that should have been searched. http://bugs.gentoo.org/show_bug.cgi?id=86031 I also noticed that CONFIG_SECURITY can add a 5th: attr, and performed a similar fix on the task directories too.

2005-05-01[PATCH] move SA_xxx defines to linux/signal.hStas Sergeev23-280/+11
The attached patch moves the IRQ-related SA_xxx flags (namely, SA_PROBE, SA_SAMPLE_RANDOM and SA_SHIRQ) from all the arch-specific headers to linux/signal.h. This looks like a left-over after the irq-handling code was consolidated. The code was moved to kernel/irq/*, but the flags are still left per-arch. Right now, adding a new IRQ flag to the arch-specific header, like this patch does: http://cvs.sourceforge.net/viewcvs.py/*checkout*/alsa/alsa-driver/utils/patches/pcsp-kernel-2.6.10-03.diff?rev=1.1 no longer works, it breaks the compilation for all other arches, unless you add that flag to all the other arch-specific headers too.

2005-05-01[PATCH] nice and rt-prio rlimitsMatt Mackall4-8/+27
Add a pair of rlimits for allowing non-root tasks to raise nice and rt priorities. Defaults to traditional behavior. Originally written by Chris Wright. The patch implements a simple rlimit ceiling for the RT (and nice) priorities a task can set. The rlimit defaults to 0, meaning no change in behavior by default. A value of 50 means RT priority levels 1-50 are allowed. A value of 100 means all 99 privilege levels from 1 to 99 are allowed. CAP_SYS_NICE is blanket permission.

The memory setup didn't take care of memory holes and this makes the memory management think there would be more memory available than there is in reality. That causes the OOM killer to kill processes even if there is enough memory left that can be written to the swap space.

"Without having looked at it, I'm sure that hostfs does not use buffer_heads. So setting your ->set_page_dirty a_op to point at __set_page_dirty_nobuffers() is a reasonable thing to do - it'll provide a slight speedup."

We must only insert the right #defines to inject the changes we need from the i386 syscall table (for instance some different function names); also, we don't implement some i386 syscalls, as ioperm(), nor some TLS-related ones (yet to provide).

2005-05-01[PATCH] x86-64: Handle empty E820 regions correctlyVenkatesh Pallipadi1-8/+18
Brings sanitize_e820_map() in x86-64 in sync with that of i386. x86_64 version was missing the changes from this patch. http://linux.bkbits.net:8080/linux-2.6/cset@3e5e4083Y3HevldZl5KCy94V4DcZww?nav=index.html|src/|src/arch|src/arch/i386|src/arch/i386/kernel|related/arch/i386/kernel/setup.c Signed-off-by: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Acked-by: Andi Kleen <ak@muc.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-05-01[PATCH] Linux 2.6.x VM86 interrupt emulation fixesPavel Pisa1-6/+9
Patch solves VM86 interrupt emulation deadlock on SMP systems. The VM86 interrupt emulation has been heavily tested and works well on UP systems after last update, but it seems to deadlock when we have used it on SMP/HT boxes now. It seems, that disable_irq() cannot be called from interrupts, because it waits until disabled interrupt handler finishes (/kernel/irq/manage.c:synchronize_irq():while(IRQ_INPROGRESS);). This blocks one CPU after another. Solved by use disable_irq_nosync. There is the second problem. If IRQ source is fast, it is possible, that interrupt is sometimes processed and re-enabled by the second CPU, before it is disabled by the first one, but negative IRQ disable depths are not allowed. The spinlocking and disabling IRQs over call to disable_irq_nosync/enable_irq is the only solution found reliable till now.

2005-05-01[PATCH] Increase number of e820 entries hard limit from 32 to 128Venkatesh Pallipadi10-18/+18
The specifications that talk about E820 map doesn't have an upper limit on the number of e820 entries. But, today's kernel has a hard limit of 32. With increase in memory size, we are seeing the number of E820 entries reaching close to 32. Patch below bumps the number upto 128. The patch changes the location of EDDBUF in zero-page (as it comes after E820). As, EDDBUF is not used by boot loaders, this patch should not have any effect on bootloader-setup code interface. Patch covers both i386 and x86-64. Tested on: * grub booting bzImage * lilo booting bzImage with EDID info enabled * pxeboot of bzImage Side-effect: bss increases by ~ 2K and init.data increases by ~7.5K on all systems, due to increase in size of static arrays.
