| * [MIPS] Change PCI host bridge setup/resourcesThomas Bogendoerfer2007-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | PCI host bridge setup for SNI RM machines with PCI is quite broken, now that Linux does it's resource setup own its own. It will use IO addresses, which are needed by the EISA config detection and assigns PCI memory addresses, which overlap with ISA legacy addresses (video ram). Below is a patch, which changes the way how the PCI memory addresses are used and sets the minimum IO address to give enough IO space for 8 EISA slots). This patch needs the other PCI resource change, I've posted. Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
| * [MIPS] Register PCI host bridge resource earlierThomas Bogendoerfer2007-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PCI based SNI RM machines have their EISA bus behind an Intel PCI/EISA bridge. So the PCI IO range must start at 0x0000. Changing that will break the PCI bus, because i8259.c already has registered it's IO addresses before the PCI bus gets initialized. Below is a patch, which will register the PCI host bridge resources inside register_pci_controller(). It also changes i8259.c to use insert_region(), because request_resource() will fail, if the IO space of the PIT hanging of the PCI host bridge (maybe passing the resource parent to init_i8259_irqs() is a cleaner fix for that).

The combination of the two is not an atomic operation, so it makes more sense to have two separate operations instead of one. In addition to the improved readability of the s390 version of SetPageUptodate, it now avoids the page_test_dirty operation which is an insert-storage-key-extended (iske) instruction which is an expensive operation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove system call glue for sys_clone, sys_fork, sys_vfork, sys_execve, sys_sigreturn, sys_rt_sigreturn and sys_sigaltstack. Call do_execve from kernel_execve directly, move pt_regs to the right place and branch to sysc_return to start the user space program. This removes the last in-kernel system call.

| * | [S390] cio: Unregister ccw devices directly.Cornelia Huck2007-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We used to unregister ccw devices not directly from the I/O subchannel remove function in order to avoid lifelocks on the css bus semaphore. This semaphore is gone, and there is no reason to not unregister the ccw device directly (it is even better since it is more in keeping with the goal of immediate disconnect).

| | | | | | | | | | | | | | | | | | | | | | | | | | | We allocage two pages when channel path measurements are enabled via cm_enable. We must not forget to free them again when channel path measurements are disabled again.
