s390/sclp: Prevent release of buffer in I/O

[ Upstream commit bf365071ea92b9579d5a272679b74052a5643e35 ]

When a task waiting for completion of a Store Data operation is
interrupted, an attempt is made to halt this operation. If this attempt
fails due to a hardware or firmware problem, there is a chance that the
SCLP facility might store data into buffers referenced by the original
operation at a later time.

Handle this situation by not releasing the referenced data buffers if
the halt attempt fails. For current use cases, this might result in a
leak of few pages of memory in case of a rare hardware/firmware
malfunction.

Pull s390 updates from Heiko Carstens:
"Besides all the small improvements and cleanups the most notable part
is the fast vector/SIMD implementation of the ChaCha20 stream cipher,
which is an adaptation of Andy Polyakov's code for the kernel.

Summary:

- add fast vector/SIMD implementation of the ChaCha20 stream cipher,
which mainly adapts Andy Polyakov's code for the kernel

- add status attribute to AP queue device so users can easily figure
out its status

- fix race in page table release code, and and lots of documentation

- remove uevent suppress from cio device driver, since it turned out
that it generated more problems than it solved problems

- quite a lot of virtual vs physical address confusion fixes

- various other small improvements and cleanups all over the place"

s390/sclp_sd: use default_groups in kobj_type

There are currently 2 ways to create a set of sysfs files for a
kobj_type, through the default_attrs field, and the default_groups
field. Move the sclp_sd sysfs code to use default_groups field which
has been the preferred way since commit aa30f47cf666 ("kobject: Add
support for default attribute groups to kobj_type") so that we can
soon get rid of the obsolete default_attrs field.

s390/sclp: sort out physical vs virtual pointers usage

Provide physical addresses whenever the hardware interface
expects it or a 32-bit value used for tracking.

Variable sclp_early_sccb gets initialized in the decompressor
and points to an address in physcal memory. Yet, it is used
as virtual memory pointer and therefore should be converted.

Note, the other two __bootdata variables sclp_info_sccb and
sclp_info_sccb_valid contain plain data, but no pointers and
do need any special care.
