Subject: [PATCH] including sysinfo.h from kernel.h makes no sense whatsoever,
 but removing it breaks glibc's userspace header, which includes kernel.h
 instead of sysinfo.h from their sys/sysinfo.h. this seems to be a historical
 mistake. on musl, including any header that uses kernel.h directly or
 indirectly plus sys/sysinfo.h will produce a compile error due to
 redefinition of struct sysinfo. so for now, only include it on glibc in order
 not to break their headers.
