SELinux: bigendian problems with filename trans rules

When writing policy via /sys/fs/selinux/policy I wrote the type and class
of filename trans rules in CPU endian instead of little endian.  On
x86_64 this works just fine, but it means that on big endian arch's like
ppc64 and s390 userspace reads the policy and converts it from
le32_to_cpu.  So the values are all screwed up.  Write the values in le
format like it should have been to start.

s390/pci/dma: use correct segment boundary size

The boundary size for iommu_area_alloc() is currently set to a constant
value. This is wrong, we shouldn't use a constant value but rather the
return value of dma_get_seg_boundary(), since a device driver can override
the default.

s390/cio: Fix missing subchannels after CHPID configure on

Performing a Channel-Path configure on operation on a Channel-Path ID
(CHPID) does not trigger a scan for subchannels that might have become
available through that CHPID. As a result, some subchannels and
associated I/O devices might be missing. Fix this by adding the missing
scan.

This problem was introduced by commit c820de39, "[S390] cio: Rework
css driver.", but wasn't noticed earlier because the machine usually
also generates a Channel-Report-Word when the first CHPID of a
subchannel is configured on, resulting in a separate scan for that
subchannel. The problem only becomes apparent when this first CHPID is
not working properly and additional working CHPIDs are subsequently
configured on without any effect on the availability of the affected
subchannel.
