2007-03-23x86-64: add "local_apic_timer_c2_ok" here tooLinus Torvalds
Needed for any architecture that claims ARCH_APICTIMER_STOPS_ON_C3, not just i386. I'm hoping Thomas will clean this up a bit later.. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

A little mistake in 8a2bfdcbfa441d8b0e5cb9c9a7f45f77f80da465 is making all transactions synchronous, which reduces ext3 performance to comical levels.

2007-03-23[PATCH] FDPIC: fix the /proc/pid/stat representation of executable boundariesDavid Howells
Fix the /proc/pid/stat representation of executable boundaries. It should show the bounds of the executable, but instead shows the bounds of the loader. Before the patch is applied, the bug can be seen by examining, say, inetd: # ps | grep inetd 610 root 0 S /usr/sbin/inetd -i # cat /proc/610/maps c0bb0000-c0bba788 r-xs 00000000 00:0b 14582157 /lib/ld-uClibc-0.9.28.so c3180000-c31dede4 r-xs 00000000 00:0b 14582179 /lib/libuClibc-0.9.28.so c328c000-c328ea00 rw-p 00008000 00:0b 14582157 /lib/ld-uClibc-0.9.28.so c3290000-c329b6c0 rw-p 00000000 00:00 0 c32a0000-c32c0000 rwxp 00000000 00:00 0 c32d4000-c32d8000 rw-p 00000000 00:00 0 c3394000-c3398000 rw-p 00000000 00:00 0 c3458000-c345f464 r-xs 00000000 00:0b 16384612 /usr/sbin/inetd c3470000-c34748f8 rw-p 00004000 00:0b 16384612 /usr/sbin/inetd c34cc000-c34d0000 rw-p 00000000 00:00 0 c34d4000-c34d8000 rw-p 00000000 00:00 0 c34d8000-c34dc000 rw-p 00000000 00:00 0 # cat /proc/610/stat 610 (inetd) S 1 610 610 0 -1 256 0 0 0 0 0 8 0 0 19 0 1 0 94392000718 950272 0 4294967295 3233480704 3233523592 3274440352 3274439976 3273467584 0 0 4096 90115 3221712796 0 0 17 0 0 0 0 The code boundaries are 3233480704 to 3233523592, which are: (gdb) p/x 3233480704 $1 = 0xc0bb0000 (gdb) p/x 3233523592 $2 = 0xc0bba788 Which corresponds to this line in the maps file: c0bb0000-c0bba788 r-xs 00000000 00:0b 14582157 /lib/ld-uClibc-0.9.28.so Which is wrong. After the patch is applied, the maps file is pretty much identical (there's some minor shuffling of the location of some of the anonymous VMAs), but the stat file is now: # cat /proc/610/stat 610 (inetd) S 1 610 610 0 -1 256 0 0 0 0 0 7 0 0 18 0 1 0 94392000722 950272 0 4294967295 3276111872 3276141668 3274440352 3274439976 3273467584 0 0 4096 90115 3221712796 0 0 17 0 0 0 0 The code boundaries are then 3276111872 to 3276141668, which are: (gdb) p/x 3276111872 $1 = 0xc3458000 (gdb) p/x 3276141668 $2 = 0xc345f464 And these correspond to this line in the maps file instead: c3458000-c345f464 r-xs 00000000 00:0b 16384612 /usr/sbin/inetd Which is now correct.

2007-03-23[PATCH] i386: add command line option "local_apic_timer_c2_ok"Thomas Gleixner
It turned out that it is almost impossible to trust ACPI, BIOS & Co. regarding the C states. This was the reason to switch the local apic timer off in C2 state already. OTOH there are sane and well behaving systems, which get punished by that decision. Allow the user to confirm that the local apic timer is trustworthy in C2 state. This keeps the default behaviour on the safe side.

2007-03-22[PATCH] lockdep: debug_show_all_locks & debug_show_held_locks vs. debug_locksJarek Poplawski
lockdep's data shouldn't be used when debug_locks == 0 because it's not updated after this, so it's more misleading than helpful. PS: probably lockdep's current-> fields should be reset after it turns debug_locks off: so, after printing a bug report, but before return from exported functions, but there are really a lot of these possibilities (e.g. after DEBUG_LOCKS_WARN_ON), so, something could be missed. (Of course direct use of this fields isn't recommended either.)

It causes extra moon icons blinking on x60, and breaks at least two other systems. During resume, we do not know that "reboot"/"shutdown" method was used, so we assume "plaform" and call BIOS, anyway... This is 2.6.21 material, and should fix 2 or 3 regressions from 2.6.20.

2007-03-22[PATCH] i386: disable local apic timer via command line or dmi quirkThomas Gleixner
The local APIC timer stops to work in deeper C-States. This is handled by the ACPI code and a broadcast mechanism in the clockevents / tick managment code. Some systems do not expose the deeper C-States to the kernel, but switch into deeper C-States behind the kernels back. This delays the local apic timer interrupts for ever and makes the systems unusable. Add a command line option to disable the local apic timer and a dmi quirk for known broken systems. Andi sayeth: While not wrong by itself i think it is still better to use some heuristic -- like "has battery in ACPI" With the DMI table if the problem is more wide spread we will just continue extending it. But anyways should be ok now for .21 although I'm not really happy with it.

2007-03-22[PATCH] i386: clockevents fix breakage on Geode/Cyrix PIT implementationsThomas Gleixner
The PIT has no dedicated mode for shut down. The only way to disable PIT is to put it into one shot mode. AMD implementations of PIT on Geode (also observed on Cyrix) are confused by an "empty" transition from CLOCK_EVT_MODE_UNUSED to CLOCK_EVT_MODE_SHUTDOWN, which puts the PIT into one shot mode momentarily. I realized after staring helpless at the bug report http://bugzilla.kernel.org/show_bug.cgi?id=8027 for quite a while, that the only change, which might influence the bogomips calibration, is the above transition during the PIT initialization. Avoiding the unnecessary switch to oneshot and later to periodic mode fixes the weird bogomips value and also the resulting slowness. The fix is confirmed on OLPC and another Geode based box.

When a file had a dos attribute of 0x1 (readonly - but dos attribute of archive was not set) - doing chmod 0777 or equivalent would try to set a dos attribute of 0 (which some servers ignore) rather than ATTR_NORMAL (0x20) which most servers accept. Does not affect servers which support the CIFS Unix Extensions.

2007-03-22IB/ipoib: Fix thinko in packet length checksMichael S. Tsirkin
The packet length checks in ipoib are broken: we add 4 bytes (IPoIB encapsulation header) when sending a packet, not 20 bytes (hardware address length) to each packet. Therefore, if connected mode is enabled so that the interface MTU is larger than the multicast MTU, IPoIB may end up trying to send too-long multicast packets. For example, multicast is broken if a message of size 2048 bytes is sent on an interface with UD MTU 2048, because 2048 is bigger than the real limit of 2044 but the code tests against the wrong limit of 2060.
