* [PATCH] s390: cleanup KconfigMartin Schwidefsky2006-01-0660-208/+183
| | | | | | | | | | Sanitize some s390 Kconfig options. We have ARCH_S390, ARCH_S390X, ARCH_S390_31, 64BIT, S390_SUPPORT and COMPAT. Replace these 6 options by S390, 64BIT and COMPAT.

| | | | | | | | | | | When the sclp_cpi module is loaded on a system which does not support the required SCLP call (e.g. on z/VM), ENOSUPP is returned to user space.

| | | | | | | | | | | | Add support for multiple subchannel sets. Works with arbitrary devices in subchannel set 1 and is transparent to device drivers.

* [PATCH] s390: qdio V=V pass-throughFrank Pavlic2006-01-065-156/+556
| | | | | | | | | | | | | | | | | | | New feature V=V qdio pass-through. QDIO and HiperSockets processing in z/VM V=V guest environments (as well as V=R with z/VM running in LPAR mode) requires shadowing of all QDIO architecture queue elements. Especially the shadowing of SBALs and SLSBs structures in the hypervisor, and the need to issue SIGA SYNC operations to observe state changes, eventually causes significant CPU processing overhead in the hypervisor. The QDIO pass-through support for V=V guests avoids the shadowing of SBALs and SLSBs. This significantly reduces the hypervisor overhead for QDIO based I/O.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch cleans up the umid code: - The only_if_set argument to get_umid is gone. - get_umid returns an empty string rather than NULL if there is no umid. - umid_is_random is gone since its users went away. - Some printfs were turned into printks because the code runs late enough that printk is working. - Error paths were cleaned up. - Some functions now return an error and let the caller print the error message rather than printing it themselves. This eliminates the practice of passing a pointer to printf or printk in, depending on where in the boot process we are. - Major tidying of not_dead_yet - mostly error path cleanup, plus a comment explaining why it doesn't react to errors the way you might expect. - Calls to os_* interfaces that were moved under os are changed back to their native libc forms. - snprintf, strlcpy, and their bounds-checking friends are used more often, replacing by-hand bounds checking in some places.

* [PATCH] uml: separate libc-dependent umid codeJeff Dike2006-01-067-339/+324
| | | | | | | | | | | | | | | | I reworked Gennady's umid OS abstraction patch because the code shouldn't be moved entirely to os. As it turns out, I moved most of it anyway. This patch is the minimal one needed to move the code and have it work. It turns out that the concept of the umid is OS-independent, but almost everything else about the implementation is OS-dependent. This is code movement without cleanup - a follow-on patch tidies everything up without shuffling code around.

* [PATCH] uml: Simplify console opening/closing and irq registrationJeff Dike2006-01-066-166/+137
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch simplifies the opening and closing of host console devices and the registration and deregistration of IRQs. The intent is to make it obvious that an IRQ can't exist without an open file descriptor. chan_enable will now open the channel, and when both opening and IRQ registration are desired, this should be used. Opening only is done for the initial console, so that interface still needs to exist. The free_irqs_later interface is now gone. It was intended to avoid freeing an IRQ while it was being processed. It did this, but it didn't eliminate the possiblity of free_irq being called from an interrupt, which is bad. In its place is a list of irqs to be freed, which is processed by the signal handler just before exiting. close_one_chan now disables irqs. When a host device disappears, it is just closed, and that disables IRQs. The device id registered with the IRQ is now the chan structure, not the tty. This is because the interrupt arrives on a descriptor associated with the channel. This caused equivalent changes in the arguments to line_timer_cb. line_disable is gone since it is not used any more. The count field in the line structure is gone. tty->count is used instead. The complicated logic in sigio_handler with freeing IRQs when necessary and making sure its idea of the next irq is correct is now much simpler. The irq list can't be rearranged underneath it, so it is now a simple list walk.

* [PATCH] uml: use kstrdupJeff Dike2006-01-064-8/+8
| | | | | | | | | | | | There were a bunch of calls to uml_strdup dating from before kstrdup was introduced. This changes those calls. It doesn't eliminate the definition since there is still a couple of calls in userspace code (which should probably call the libc strdup).
