2006-12-04[S390] Don't use small stacks when lockdep is used.Heiko Carstens1-1/+1

If the last path to a device is gone after a chpid has been varied off, putting it on the slow queue doesn't prevent a device driver from still attempting to use it (it may stay on the slow queue for a long time). Instead, trigger a verify event which will prevent I/O attempts from the device driver immediately.

VMALLOC_END on 31bit should be 0x8000000UL instead of 0x7fffffffL. The page mask which is used to make sure memory_end is on 4MB/2MB boundary is wrong and not needed. Therefore remove it.

2006-12-04[S390] cio: Make ccw_dev_id_is_equal() more robust.Cornelia Huck1-1/+4

2006-12-04[S390] Add dynamic size check for usercopy functions.Gerald Schaefer4-59/+190
Use a wrapper for copy_to/from_user to chose the best usercopy method.

2006-12-04[S390] Misaligned wait PSW at memory detection.Heiko Carstens1-1/+2
If the memory detection code would ever reach the point where it would load the wait psw, it would generate a specification exception and the system would crash at ipl time. This is because of a misaligned wait psw. It needs to be on a double word boundary instead of a word boundary.

2006-12-04[S390] cpu shutdown reworkHeiko Carstens5-180/+58

2006-12-04[S390] Bad kexec control page allocation.Heiko Carstens1-1/+1
KEXEC_CONTROL_MEMORY_LIMIT is an unsigned long value and therefore should be defined as one.

2006-12-04[S390] Reset infrastructure for re-IPL.Heiko Carstens13-108/+246
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.

2006-12-04[S390] Use diag instead of ccw reipl.Michael Holzheu1-0/+2
Since the diag 308 reipl method is superior to the ccw method, we should use it whenever it is possible.
