* [S390] virtio console: fix section mismatch warning.Heiko Carstens2008-08-011-1/+1
| | | | | | | | | | | | | | | | | | | | Fix these two false positive warnings: WARNING: vmlinux.o(.text+0x2e1cc4): Section mismatch in reference from the function s390_virtio_console_init() to the function .init.text:early_put_chars() The function s390_virtio_console_init() references the function __init early_put_chars(). This is often because s390_virtio_console_init lacks a __init annotation or the annotation of early_put_chars is wrong. WARNING: vmlinux.o(.text+0x2e1cd0): Section mismatch in reference from the function s390_virtio_console_init() to the function .init.text:virtio_cons_early_init() The function s390_virtio_console_init() references the function __init virtio_cons_early_init().

* [S390] qdio: fix section mismatch bug.Heiko Carstens2008-08-012-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | Fix the two section mismatch warnings below. This fixes two real bugs since the code which has __exit annotations may already be gone when it is called. WARNING: vmlinux.o(.init.text+0x1cc4a): Section mismatch in reference from the function init_QDIO() to the function .exit.text:qdio_setup_exit() The function __init init_QDIO() references a function __exit qdio_setup_exit(). This is often seen when error handling in the init function uses functionality in the exit path. The fix is often to remove the __exit annotation of qdio_setup_exit() so it may be used outside an exit section. WARNING: vmlinux.o(.init.text+0x1cc7a): Section mismatch in reference from the function init_QDIO() to the function .exit.text:qdio_remove_perf_stats() The function __init init_QDIO() references a function __exit qdio_remove_perf_stats(). This is often seen when error handling in the init function uses functionality in the exit path. The fix is often to remove the __exit annotation of qdio_remove_perf_stats() so it may be used outside an exit section.

* [S390] nohz/sclp: disable timer on synchronous waits.Heiko Carstens2008-08-011-2/+4
| | | | | | | | | | | sclp_sync_wait wait synchronously for an sclp interrupt and disables timer interrupts. However on the irq enter paths there is an extra check if a timer interrupt would be due and calls the timer callback. This would schedule softirqs in the wrong context. So introduce local_tick_enable/disable which prevents this. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
* [S390] dasd: Add support for enhanced VM UIDStefan Weinhuber2008-08-015-163/+189
| | | | | | | | | | | | When z/VM provides two virtual devices (minidisks) that reside on the same real device, both will receive the configuration data from the real device and thus get the same uid. To fix this problem, z/VM provides an additional configuration data record that allows to distinguish between minidisks. z/VM APAR VM64273 needs be installed so this fix has an effect.

* KVM: s390: Fix guest kconfigChristian Borntraeger2008-07-271-1/+1
| | | | | | | | | | | | | | | | | | | | | Cornelia Huck noticed that a modular virtio without kvm guest support leads to a build error in the s390 virtio transport: CONFIG_VIRTIO=m leads to ERROR: "vmem_add_mapping" [drivers/s390/kvm/kvm_virtio.ko] undefined! ERROR: "max_pfn" [drivers/s390/kvm/kvm_virtio.ko] undefined! ERROR: "vmem_remove_mapping" [drivers/s390/kvm/kvm_virtio.ko] undefined! The virtio transport only works with kvm guest support and only as a builtin. Lets change the build process of drivers/s390/kvm/kvm_virtio.c to depend on kvm guest support, which is also a bool. CONFIG_S390_GUEST already selects CONFIG_VIRTIO, that should prevent CONFIG_S390_GUEST=y CONFIG_VIRTIO=n situations.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When zfcp receives 16 unsolicited status messages, this could trigger an adapter reopen. In this case, first try to send a new status read, and only if this fails, go through the recovery.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some situations the auto port attachment task is started before the ERP is finished. To prevent this unwanted situation we wait until the adapter is up and running before we start our work.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Automatically attach the remote ports in zfcp when the adapter is set online. This is done by querying all available ports from the FC namesever. The scan for remote ports is also triggered by RSCNs and can be triggered manually with the sysfs attribute 'port_rescan'.
