[S390] qdio: Split SBAL entry flags

2011-06-06T12:14:56+00:00

The qdio SBAL entry flag is made-up of four different values that are
independent of one another. Some of the bits are reserved by the
hardware and should not be changed by qdio. Currently all four values
are overwritten since the SBAL entry flag is defined as an u32.

Split the SBAL entry flag into four u8's as defined by the hardware
and don't touch the reserved bits.

[S390] irq: fix service signal external interrupt handling

2011-05-26T07:48:24+00:00

Interrupt sources like pfault, sclp, dasd_diag and virtio all use the
service signal external interrupt subclass mask in control register 0
to enable and disable the corresponding interrupt.
Because no reference counting is implemented each subsystem thinks it
is the only user of subclass and sets and clears the bit like it wants.
This leads to case that unloading the dasd diag module under z/VM
causes both sclp and pfault interrupts to be masked. The result will
be locked up system sooner or later.
Fix this by introducing a new way to set (register) and clear
(unregister) the service signal subclass mask bit in cr0.
Also convert all drivers.

[S390] get CPC image name

2011-05-23T08:24:32+00:00

Provide sysfs attributes that contain the CPC name and the HMC network
name of the machine the operating system is running on. This information
is retrieved with the operation communication parameters (OCF) sclp
interface.
