Thomas Richter 1f8e50722f s390/cpum_sf: sampling buffer setup to handle virtual addresses
The CPU Measurement Sampling Facility (CPUM_SF) installs large buffers
to save samples collected by hardware. These buffers are organized
as Sample Data Buffer Tables (SDBT) and Sample Data Buffers (SDB).
SDBs contain the samples which are extracted and saved in the perf
ring buffer.
The SDBTs are chained using real addresses and refer to SDBs using
real addresses.

Adds proper virtual to phyiscal address translation to the buffer
chaining. The current constraint which requires virtual equals real
address layout is removed.
