commit cb44a620ef2336449af60694b6696efced161774
Author: Stefan Liebler <stli@linux.ibm.com>

S390: Add PCI_MIO and SIE HWCAPs
Both new HWCAPs were introduced in these kernel commits:
- 7e8403ecaf884f307b627f3c371475913dd29292
"s390: add HWCAP_S390_PCI_MIO to ELF hwcaps"
- 7e82523f2583e9813e4109df3656707162541297
"s390/hwcaps: make sie capability regular hwcap"
Also note that the kernel commit 511ad531afd4090625def4d9aba1f5227bd44b8e
"s390/hwcaps: shorten HWCAP defines" has shortened the prefix of the macros
from "HWCAP_S390_" to "HWCAP_". For compatibility reasons, we do not
change the prefix in public glibc header file.
(cherry picked from commit f2e06656d04a9fcb0603802a4f8ce7aa3a1f055e)
