Kill all isa-related stuff from i2c_detect, it's not used anymore. This is one major step in the directiom of merging i2c_probe and i2c_detect. The last obstacle I can think of is the different way forced addresses work between sensors and non-sensors i2c drivers. I'll deal with that in a later patchset.

Call the ISA chip drivers detection function directly instead of relying on i2c_detect. The net effect is that address lists won't be handled anymore, but they were mostly useless in the ISA case anyway (pc87360, smsc47m1, smsc47b397 had already dropped them). We don't need to handle multiple devices, all we may need is a way to force a given address instead of the original one (some drivers already do: sis5595, via686a, w83627hf), and, for drivers supporting multiple chips, a way to force one given kind. All this may be added later on demand, but I actually don't think there will be much demand. Signed-off-by: -

All ISA hardware monitoring drivers (including hybrid drivers) now have a hard dependency on i2c-isa, so they must select I2C_ISA. As a result, CONFIG_I2C_ISA doesn't need to be left visible to the user. The good thing here is that users will stop complaining that some driver doesn't work just because they forgot to compile or load i2c-isa. At this point, all drivers are working again and the cleanup phase can begin. Signed-off-by: -

Convert the 10 ISA hardware monitoring drivers (it87, lm78, pc87360, sis5595, smsc47b397, smsc47m1, via686a, w83627hf, w83627ehf, w83781d) to explicitely register with i2c-isa. For hybrid drivers (it87, lm78, w83781d), we now have two separate instances of i2c_driver, one for the I2C interface of the chip, and one for ISA interface. In the long run, the one for ISA will be replaced with a different driver type. At this point, all drivers are working again, except for missing dependencies in Kconfig. Signed-off-by: -

Convert i2c-isa from a dumb i2c_adapter into a pseudo i2c-core for ISA hardware monitoring drivers. The isa i2c_adapter is no more registered with i2c-core, drivers have to explicitely connect to it using the new i2c_isa_{add,del}_driver interface. At this point, all ISA chip drivers are useless, because they still register with i2c-core in the hope i2c-isa is registered there as well, but it isn't anymore. The fake bus will be named i2c-9191 in sysfs. This is the number it already had internally in various places, so it's not exactly new, except that now the number is seen in userspace as well. This shouldn't be a problem until someone really has 9192 I2C busses in a given system ;) The fake bus will no more show in "i2cdetect -l", as it won't be seen by i2c-dev anymore (not being registered with i2c-core), which is a good thing, as i2cdetect/i2cdump/i2cset cannot operate on this fake bus anyway.

Drop the separate client name for the LM78-J chip. This is really only a later revision of the LM78, with almost no difference and no difference the driver handles in any case. This was the only client name that had a dash in it, and special care had to be taken in libsensors because of it. As we plan to write a new library soon, I'd like to get rid of this exception before we do. As a nice side effect, it saves 876 bytes in lm78.ko. Signed-off-by:

The LM75 initialization is a bit agressive, it arbitrarily reconfigures the chip. Make it only change the bit it needs. This is a port from the 2.4 kernel version of the driver (lm_sensors). Signed-off-by:

attached is a small patch that removes unused code from i2c-nforce2 and adds a single debug message. The patch is against 2.6.13-rc3-mm1. I have tested the patch with 2.6.13-rc3: compiles cleanly and works as without the patch (as expected). Signed-off-by:

This is an update to the max6875 driver. It no longer does any detection, so the address must be forced on module load. It only makes available the user EEPROM (read-only). This patch is based off 2.6.13-rc2-mm2. Signed-off-by:

On s390 the lock value used for spinlocks consists of the lower 32 bits of the PSW that holds the lock. If this address happens to be on a four gigabyte boundary the lock is left unlocked. This allows other cpus to grab the same lock and enter a lock protected code path concurrently. In theory this can happen if the vmalloc area for the code of a module crosses a 4 GB boundary.

There is a race in pfault_interrupt. That function gets called two times for each pfault notification. Once with a subcode of 0 to indicate that a real page is not available and once with a subcode of 0x80 to indicate that the page is present again. Since the two external interrupts can be delivered on two different cpus the order in which the two calls are made is unpredictable. It is possible that the subcode 0x80 interrupt is completed before the subcode 0x00 interrupt has done the wake_up() call. To avoid calling wake_up() on an already removed task structure proper task structure reference counting is needed. Increase the reference counter in the subcode 0x00 interrupt before setting pfault_wait to zero and return the reference after the wake_up call. Signed-off-by:

Reintroduce a read-only copy of the devmap features in the device struct. This is necessary to solve a deadlock on the dasd_devmap_lock which is acquired by dasd_get_features called from the dasd tasklet. The current implementation of devmap doesn't allow to call any devmap function from interrupt or softirq context. Signed-off-by:

debug feature changes/bug fixes: - Use get_clock() function instead of private inline assembly. - Use 'struct timeval' instead of 'struct timespec' for call to tod_to_timeval(). Now the microsecond part of the timestamp is correct again. - Fix a locking problem: when creating a snapshot of the current content of the debug areas, lock the entire debug_info object.

The new machine check handler still has a few bugs. 1) The system entry time has to be stored in the machine check handler, 2) the machine check return psw may not be stored at the usual place because it might overwrite the return psw of the interrupted context, 3) the return address for the call to s390_handle_mcck in the i/o interrupt handler is not correct, 4) the system call cleanup has to take the different save area of the machine check handler into account, 5) the machine check handler may not call UPDATE_VTIME before CREATE_STACK_FRAME, and 6) the io leave path needs a critical section cleanup to make sure that the TIF_MCCK_PENDING bit is really checked before switching back to user space.

Change syscall-stub's data to include a "expected retval". Stub now checks syscalls retval and aborts execution of syscall list, if retval != expected retval. run_syscall_stub prints the data of the failed syscall, using the data pointer and retval written by the stub to the beginning of the stack. one_syscall_stub is removed, to simplify code, because only some instructions are saved by one_syscall_stub, no host-syscall. Using the stub with additional data (modify_ldt via stub) is prepared also. Signed-off-by:

This change enables SKAS0/SKAS3 to work with all combinations of /proc/mm and PTRACE_FAULTINFO being available or not. Also it changes the initialization of proc_mm and ptrace_faultinfo slightly, to ease forcing SKAS0 on a patched host. Forcing UML to run without /proc/mm or PTRACE_FAULTINFO by cmdline parameter can be implemented with a setup resetting the related variable. Signed-off-by:
