| * i2c: Convert some more new-style drivers to use module aliasingJean Delvare2008-05-115-1/+29
| | | | | | | | | | | | | | | | Update 3 more new-style i2c drivers to use standard module aliasing instead of the old driver_name/type driver matching scheme. These video drivers aren't used yet so converting them is trivial. Signed-off-by: Jean Delvare <khali@linux-fr.org>
| * i2c: Match dummy devices by typeJean Delvare2008-05-113-8/+10
| | | | | | | | | | | | | | | | | | | | | | | | As the old driver_name/type matching scheme is going away soon, change the dummy device mechanism to use the new matching scheme. This has the downside that dummy i2c clients can no longer choose their name, they'll all appear as "dummy" in sysfs and in log messages. I don't think it is a problem in practice though, as there is little reason to use these i2c clients to log messages. Signed-off-by: Jean Delvare <khali@linux-fr.org>

| * i2c: Improve smbus-protocol documentationDavid Brownell2008-05-111-35/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Improve the smbus-protocol documentation file somewhat: - Use the names of the SMBus protocol operations (from the 2.0 specification), not made-up-for-Linux names. - Add the name of the call used to execute each operation ... and point out that there are mismatches, where functions execute different protocol operations than their names specify. The most confusing examples are that "Read Byte" isn't executed by i2c_smbus_read_byte(), and that "Write Byte" isn't executed by i2c_smbus_write_byte(). When coding, that's not as bad as it may seem; but that case would seem to be worth fixing.

| * i2c-piix4: Blacklist two mainboardsJean Delvare2008-05-111-2/+30
| | | | | | | | | | | | | | | | | | | | We had a report that running sensors-detect on a Sapphire AM2RD790 motherbord killed the CPU. While the exact cause is still unknown, I'd rather play it safe and prevent any access to the SMBus on that machine by not letting the i2c-piix4 driver attach to the SMBus host device on that machine. Also blacklist a similar board made by DFI. Signed-off-by: Jean Delvare <khali@linux-fr.org>
| * i2c-piix4: Increase the intitial delay for the ServerWorks CSB5David Milburn2008-05-111-3/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Per the PIIX4 errata, there maybe a delay between setting the start bit in the Smbus Host Controller Register and the transaction actually starting. If the driver doesn't delay long enough, it may appear that the transaction is complete when actually it hasn't started, this may lead to bus collisions. While 1 ms appears to be enough for most chips, the ServerWorks CSB5 wants 2 ms. Signed-off-by: David Milburn <dmilburn@redhat.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>

| | | | | | | | | | | | | | | | | | Alter the mpc i2c driver to use the NO_IRQ symbol instead of the constant zero when checking for valid interrupts. NO_IRQ=-1 on ppc and NO_IRQ=0 on powerpc so the checks against zero are not correct. Signed-off-by: Jon Smirl <jonsmirl@gmail.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
* | Add new 'cond_resched_bkl()' helper functionLinus Torvalds2008-05-123-4/+6
|/ | | | | | | | | | | | | | | | | | It acts exactly like a regular 'cond_resched()', but will not get optimized away when CONFIG_PREEMPT is set. Normal kernel code is already preemptable in the presense of CONFIG_PREEMPT, so cond_resched() is optimized away (see commit 02b67cc3ba36bdba351d6c3a00593f4ec550d9d3 "sched: do not do cond_resched() when CONFIG_PREEMPT"). But when wanting to conditionally reschedule while holding a lock, you need to use "cond_sched_lock(lock)", and the new function is the BKL equivalent of that. Also make fs/locks.c use it.

| * sparc: Fix debugger syscall restart interactions.David S. Miller2008-05-1117-119/+115
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So, forever, we've had this ptrace_signal_deliver implementation which tries to handle all of the nasties that can occur when the debugger looks at a process about to take a signal. It's meant to address all of these issues inside of the kernel so that the debugger need not be mindful of such things. Problem is, this doesn't work. The idea was that we should do the syscall restart business first, so that the debugger captures that state. Otherwise, if the debugger for example saves the child's state, makes the child execute something else, then restores the saved state, we won't handle the syscall restart properly because we lose the "we're in a syscall" state. The code here worked for most cases, but if the debugger actually passes the signal through to the child unaltered, it's possible that we would do a syscall restart when we shouldn't have. In particular this breaks the case of debugging a process under a gdb which is being debugged by yet another gdb. gdb uses sigsuspend to wait for SIGCHLD of the inferior, but if gdb itself is being debugged by a top-level gdb we get a ptrace_stop(). The top-level gdb does a PTRACE_CONT with SIGCHLD to let the inferior gdb see the signal. But ptrace_signal_deliver() assumed the debugger would cancel out the signal and therefore did a syscall restart, because the return error was ERESTARTNOHAND. Fix this by simply making ptrace_signal_deliver() a nop, and providing a way for the debugger to control system call restarting properly: 1) Report a "in syscall" software bit in regs->{tstate,psr}. It is set early on in trap entry to a system call and is fully visible to the debugger via ptrace() and regsets. 2) Test this bit right before doing a syscall restart. We have to do a final recheck right after get_signal_to_deliver() in case the debugger cleared the bit during ptrace_stop(). 3) Clear the bit in trap return so we don't accidently try to set that bit in the real register. As a result we also get a ptrace_{is,clear}_syscall() for sparc32 just like sparc64 has. M68K has this same exact bug, and is now the only other user of the ptrace_signal_deliver hook. It needs to be fixed in the same exact way as sparc. Signed-off-by: David S. Miller <davem@davemloft.net>
| * sparc: Fix ptrace() detach.David S. Miller2008-05-114-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | Forever we had a PTRACE_SUNOS_DETACH which was unconditionally recognized, regardless of the personality of the process. Unfortunately, this value is what ended up in the GLIBC sys/ptrace.h header file on sparc as PTRACE_DETACH and PT_DETACH. So continue to recognize this old value. Luckily, it doesn't conflict with anything we actually care about. Signed-off-by: David S. Miller <davem@davemloft.net>

Since we now clear the RCSR status from the SoC specific PXA PM code and before reset in the arch_reset() function, the duplication in the corgi, poodle, spitz and tosa code can be removed.

The first is a comparison where a byte will probably wrap around to 0 instead of being saturated to 255, shouldn't be triggered very often but need fixing. The second is an attempt by the driver to adjust MCLK down to the maximum frequency according to the spec, so we don't accidentally overclock the PL18x block. None of the mach-{versatile|integrator|lh7a40x} that use it in-tree seem to have a problem with this (all are well below 100MHz, typically 33MHz), but some day there will be a problem. This is not applied on top of the earlier mmci patch for race condition but rather a clean 2.6.25, but I guess it applies without major protests anyway.

All parts of asm-i386/topology.h has come under #ifdef CONFIG_NUMA after the merge to asm-x86/topology.h /sys/devices/system/cpu/cpu?/topology/* is populated based on ENABLE_TOPO_DEFINES The sysfs cpu topology is not being populated on my dual socket dual core xeon 5160 processor based (x86 32 bit) system. CONFIG_NUMA is not set in my case yet the topology is relevant and useful. irqbalance daemon application depends on topology to build the cpus and package list and it fails on Fedora9 beta since the sysfs topology was not being populated in the 2.6.25 kernel. I am not sure if it was intentional to not define ENABLE_TOPO_DEFINES for non-numa systems. This fix has been tested on the above mentioned dual core, dual socket system.

It gets to the point where it has shown the default X mouse cursor logo (a big X / cross) and does not respond to anything from that point on. This worked fine before 709f744, and it works fine with 709f744 reverted on top of Linus' current tree (f74d505). The revert had conflicts, as far as I can tell due to white space changes. The diff I ended up with is below. It is 100% reproducible. Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
| * | | | | x86: restrict keyboard io ports reservation to make ipmi driver workHelge Wagner2008-05-102-2/+9

Trying to load the openipmi driver fails, because the ports (0x62/0x66) are reserved for keyboard. keyboard reserves the full range 0x60-0x6F while it doesn't need to. Reserve only ports 0x60 and 0x64 for the legacy PS/2 i8042 keyboad controller instead of 0x60-0x6F to allow the openipmi driver to work.

Its moved to addon_cpuid_features.c as this file is shared between 32 and 64 bit. Remove the manipulation of the PAT feature bit and just disable PAT in the PAT layer, based on the PAT bit provided by the CPU and the current CPU version/model white list. Change the boot CPU check so it works on Voyager somewhere in the future as well :) Also panic, when a secondary has PAT disabled but the primary one has alrady switched to PAT. We have no way to undo that. The white list is kept for now to ensure that we can rely on known to work CPU types and concentrate on the software induced problems instead of fighthing CPU erratas and subtle wreckage caused by not yet verified CPUs. Once the PAT code has stabilized enough, we can remove the white list and open the can of worms. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>
