[S390] Fix pte type checking.

2006-10-18T16:30:51Z

handle_pte_fault uses pte_present, pte_none and pte_file to find out the type of a pte. That is done without holding the page table lock. This clashes with the way how ptep_clear_flush removes active page table entries from the system. First the ipte instruction is used to invalidate the pte and remove all plt entries for the page. The ipte sets the hardware invalid bit without changing any other bit. After the ipte finished the pte is cleared. A concurrent fault can observe the the previously valid pte with the invalid bit set. With the current encoding of the different pte types an invalidated read-only pte can be misinterpreted as a swap-pte. Signed-off-by: Martin Schwidefsky

[S390] cio: Use ccw_dev_id and subchannel_id in ccw_device_private

2006-10-11T13:31:38Z

Use the proper structures to identify device and subchannel. Change get_disc_ccwdev_by_devno() to get_disc_ccwdev_by_dev_id(). Signed-off-by: Cornelia Huck Signed-off-by: Martin Schwidefsky

[S390] irq change improvements.

2006-10-11T13:31:26Z

Remove the last few places where a pointer to pt_regs gets passed. Also make sure we call set_irq_regs() before irq_enter() and after irq_exit(). This doesn't fix anything but makes sure s390 looks the same like all other architectures. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

[S390] incorrect placement of include.

2006-10-04T18:02:12Z

The include of linux/smp.h needs to be done before the #if that checks for the compiler version. Seems like fallout from the inline assembly cleanup patch vs. the directed yield patch. Signed-off-by: Martin Schwidefsky
