1. establish type independence for ease in porting and,
2. provide a visual queue as to which syscalls have proper
prototypes to further cleanup the i386/alpha split.
Linuxulator types are prefixed by 'l_'. void and char have not
been "virtualized".
o Provide dummy functions for all unimplemented syscalls, except for
the osf1 syscalls. This can only be done if the osfulator
implements at least all syscalls used by the linuxulator. Remove
dummy functions for syscalls that are now truely unimplemented.
o Set the syscall namespace as follows: Mark a syscall as OSF1 if
the Linux kernel has prefixed the syscall with 'osf_' and has
provided special implementations for it. Otherwise mark the
syscall as LINUX by default. Some of the LINUX syscalls remain
marked as BSD or POSIX.
o Rename syscalls so they match the names used in the Linux kernel.
Also, provide more accurate prototypes. This generally improves
cross-referencing and reduces head-scratching.
o Fix the (g|s)etresuid syscalls. They mapped to (g|s)etresgid.
o Sanitize the the shm*, sem* and msg* syscalls. Their prototypes
were dictated by the way these syscalls were used in the i386
code. That has been fixed. NOTE: linux_semctl now passes it's
'arg' parameter by value and not by reference.
o Fix prototype of linux_utime. It takes a struct timeval, not a
struct utimbuf.
o Fix the linux_sysfs syscall. It's index is not 255, but 254.
o Implement the following syscalls:
linux_sysctl
o Add the following new syscalls:
(g|s)etresgid
linux_pivot_root (dummy)
linux_mincore (dummy)
linux_pciconfig_iobase (dummy)
linux_getdents64

o Provide seperate implementations for the 16-bit uid_t and gid_t
based syscalls as Linux used to have. The new 32-bit uid_t and
gid_t based syscalls now map to their FreeBSD equivalents.
o Fix the linux_ipc syscall so that it doesn't force the shm*, sem*
and msg* syscalls to have the same syscall. The prototypes for
these syscalls now match the those used on Alpha. While here,
add the same kludge for MSGRCV as is present in the Linux kernel.
o Implement the following syscalls:
linux_stat64, linux_lstat64 and linux_fstat64
linux_sysctl
o Added syscalls numbered 198 - 221. This include:
- the 32-bit uid_t and gid_t bases syscalls
- 64-bit file offset/size based syscalls
to resume a transfer, download the requested document into a temporary file
which we later rename. This avoids leaving half-completed files around in
case of a crash (it'll still leave a half-completed file, but with a hope-
fully non-conflicting name), and should reduce the need for human inter-
vention on ports-building machines.
The temporary file name for "foo/bar" is constructed by invoking mkstemps()
with the pattern "foo/.fetch.XXXXXX.bar"

of repeating unsuccessful lseek call on each write (original stdio bug).
2) Save errno accross _sseek call in _swrite to not touch it in case write
success (original stdio bug).
3) Add _sseek error checking back, but only for __SOPT mode now.
The compatibility glue is still provided.
(This change is not yet reflected in the manpage, nor
in usage(). This will be fixed at a later time today,
with the general manpage cleanup commit.)
This is a first cut, but enough to help people interested in using it
further than before.
More text coming to illustrate use and provide more details.

allow an in-kernel webserver (or similar) to accept
and handle incoming connections using netgraph without ever leaving the
kernel. (allows incoming tunnel requests to be
handled totally within the kernel for example)
Needs work, but shouldn't break existing functionality.

Avoid fully initialising the ACPI namespace if we are attempting to avoid
parts of it. This is a workaround for some systems that still crash
the interpreter.
Implement the ISA_IVAR_LOGICALID for ISA compatibility. Implement stubs
for other PnP ID-related ivars.
with non-seekable streams. Now here is what here was originally, but it is
ugly, producing unneded seek syscall on each non-seekable stream write. I'll
think about proper solution later.

This fixes the problem where a laptop booted without an AC adapter ran
at 100% CPU speed by default.
