In case of reipl cpcmd gets called when all other cpus are not running anymore. To prevent deadlocks change __cpcmd so that it doesn't take any locks and call cpcmd or __cpcmd, whatever is correct in the current context. Signed-off-by:

KEXEC_CONTROL_MEMORY_LIMIT is an unsigned long value and therefore should be defined as one. Otherwise the kexec control page can be allocated above 2GB which will cause a specification exception on the sam31 instruction in the s390 kexec relocation code. Signed-off-by:

In case of re-IPL and diag308 doesn't work we have to reset all devices manually and wait synchronously that each reset finished. This patch adds the necessary infrastucture and the first exploiter of it. Subsystems that need to add a function that needs to be called at re-IPL may register/unregister this function via struct reset_call { struct reset_call *next; void (*fn)(void); }; void register_reset_call(struct reset_call *reset); void unregister_reset_call(struct reset_call *reset); When the registered function get called the context is: - all cpus beside the current one are stopped - all machine checks and interrupts are disabled - prefixing is disabled - a default machine check handler is available for use The registered functions may not take any locks are sleep. For the common I/O layer part of this patch: Introduce a reset_call css_reset that does the following: - clear all subchannels - perform a rchp on all channel paths and wait for the resulting machine checks This replaces the calls to clear_all_subchannels() and cio_reset_channel_paths() for kexec and ccw reipl. reipl_ccw_dev() now uses reipl_find_schid() to determine the subchannel id for a given device id. Also remove cio_reset_channel_paths() and friends since they are not needed anymore. Signed-off-by:Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by:

segment save will exit with a lock held if the passed segment doesn't exist. Any subsequent call to segment_save will lead to a deadlock. Fix this and give up the lock before returning. Signed-off-by:

Since the diag 308 reipl method is superior to the ccw method, we should use it whenever it is possible. We can do that, if the user has not specified a new reipl ccw device and the system has been ipled from a ccw device. Signed-off-by:

If reboot fails (e.g. because wrong devno has been specified by the user), we should just stop all cpus, but should not trigger a kernel panic. Signed-off-by:

Get rid of our own user_termio_to_kernel_termios() and kernel_termios_to_user_termio() macros which didn't check for errors on user space accesses. Instead use the generic functions which handle this properly. In addition the generic version of user_termio_to_kernel_termios() also copies the c_line member which was missing in our variant.

If multiple kernel images are installed on one DASD, the loadparm can be used to select the boot configuration. This patch introduces the following two new sysfs attributes: /sys/firmware/ipl/loadparm: shows loadparm of current system (ro) /sys/firmware/reipl/ccw/loadparm: loadparm used for next reboot (rw) Signed-off-by:

When writing to dasd attributes (e.g. readonly), all values besides '1' are handled like '0'. Other sysfs-attributes like 'online' are checking for '1' and for '0' and do not accept other values. Therefore enhanced checking and error handling in dasd_devmap attribute store functions. Signed-off-by:

The SALIPL entry point has an needless memory detection routine as we later check the memory size again. The SALIPL code also uses diagnose 0x060 if we are running under VM, but this diagnose is not compatible with the 64 bit addressing mode. The solution is to get rid of this code and rely on the memory detection in the startup code. Signed-off-by:

Some helpers (namely H.323) manually assign further helpers to expected connections. This is not possible with nf_conntrack anymore since we need to know whether a helper is used at allocation time. Handle the helper assignment centrally, which allows to perform the correct allocation and as a nice side effect eliminates the need for the H.323 helper to fiddle with nf_conntrack_lock. Mid term the allocation scheme really needs to be redesigned since we do both the helper and expectation lookup _twice_ for every new connection. Signed-off-by:
