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

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] 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. The mvcos instruction is better for sizes greater than 256 bytes, if mvcos is not available a page table walk is better for sizes greater than 1024 bytes.

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 Carstens3-144/+49

2006-12-04[S390] cpcmd <-> __cpcmd calling issuesHeiko Carstens3-17/+21
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.

2006-12-04[S390] Reset infrastructure for re-IPL.Heiko Carstens8-41/+115
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. 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.

2006-12-04[S390] No panic for failed rebootMichael Holzheu1-1/+2

2006-12-04[S390] remove salipl memory detection.Christian Borntraeger1-21/+0
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.
