src/sys/compat/netbsd32: netbsd32_sysctl.c
Log Message:
Fix sysctl(3):vm.minaddress in compat_netbsd32(8)
Cast minaddress from LP64-specific long (64-bit) to 32-bit long (int).
This value is usually 0 or 0+PAGE_SIZE. There is need to change type in
order to keep original code functional, without prompting the value with
'long long' or a similar approach.
There are more CTLTYPE_LONG with a need for fixes in the compat code:
uipc_usrreq.c
1975 CTLTYPE_LONG, "sendspace",
1981 CTLTYPE_LONG, "recvspace",
1987 CTLTYPE_LONG, "sendspace",
1993 CTLTYPE_LONG, "recvspace",
vfs_bio.c
1921 CTLTYPE_LONG, "bufmem",
1928 CTLTYPE_LONG, "bufmem_lowater",
1935 CTLTYPE_LONG, "bufmem_hiwater",
