4c3a3ec075 Instead of hard coding the major numbers for IDE and SCSI disks 
look in the device's cdevsw for the D_DISK flag.

7842f151ba Map FreeBSD character device hard disks to Linux block device hard disks. 
This fixes the problem with VMWARE not being able to use raw disks.

930a65fe47 Use the linux_connect() on alpha rather than passing directly through 
to our native connect().  This is required to deal with the differences
in the way linux handles connects on non-blocking sockets.

This gets the private beta of the Compaq Linux/alpha JDK working
on FreeBSD/alpha

edc5a9dd25 Fix getdents syscall. 
The offset field in struct dirent was set to the offset of
the next dirent in rev 1.36. The offset was calculated from
the current offset and the record length. This offset does
not necessarily match the real offset when we are using
cookies. Therefore, also use the cookies to set the offset
field in struct dirent if we're using cookies to iterate
through the dirents.

e70ce4d9c5 fix linux_termio and linux_termios structs on alpha. alpha differences 
are in the termios struct (probably because linux wants to be compatible
with the osf/1 termios struct), not the termio struct.

7936339495 A start at an implemention of linux_rt_sendsig & linux_rt_sigreturn 
and associated user-level signal trampoline glue.

Without this patch, an SA_SIGINFO style handler can be installed by a linux
app, but if the handler accesses its sip argument, it will get a garbage
pointer and likely segfault.

We currently supply a valid pointer, but its contents are mainly
garbage.  Filling this in properly is future work.

This is the second of 3 commits that will get IBM's JDK 1.3 working with
FreeBSD ...

This is also the appropriate fix for exo-tree sources.

03567510a8 Add bounds checking to stackgap_alloc. Previously it was possible 
to construct a path that was long enough (ie longer than
SPARE_USRSPACE bytes) and trash the stack.

Note that SPARE_USRSPACE is much smaller than MAXPATHLEN so that
the Linuxulator will now return ENAMETOOLONG even if the path
is smaller than MAXPATHLEN.

6f6b2cd019 Linux allows to mmap annonymous with a file descriptor passed, FreeBSD 
doesn't.  In the Linux emulation layer, ignore the fd passed when
MAP_ANON is specified.

Known application to be fixed: Xanalys/Harlequin Lispworks

Also improve debug output for mmap, now showing what the emulation
layer mapped to what (-DDEBUG).
