Currently we don't accept writable file mmap()s, as there is no
system in place to guarantee dirty buffers would make it back to
disk. But we can actually accept MAP_SHARED for PROT_READ mappings,
meaning the ranges aren't writable at all (and no private copy is
made as with MAP_PRIVATE), as it turns out a fairly large class of
usage.
. fail writable MAP_SHARED mappings at runtime
. reduces some minix-specific patches
. lets binutils gold build on minix without further patching

. define _MINIX_SYSTEM for all system code from minix.service.mk
. hide some system-level declarations and definitions
behind _MINIX_SYSTEM to cleanly fix host tool build problems on
Minix (such as: NONE being defined and paddr_t being used but not
declared)
. the similar definition _SYSTEM is unsuitable as it changes the
values of errno definitions

- Fix for possible unset uid/gid in toproto
- Fix for default mtree style
- Update libelf
- Importing libexecinfo
- Resynchronize GCC, mpc, gmp, mpfr
- build.sh: Replace params with show-params.
This has been done as the make target has been renamed in the same
way, while a new target named params has been added. This new
target generates a file containing all the parameters, instead of
printing it on the console.
- Update test48 with new etc/services (Fix by Ben Gras <ben@minix3.org)
get getservbyport() out of the inner loop

. use netbsd sigframe, sigcontext struct
. netbsd sigframe *contains* sigcontext; use that directly
in kernel sigsend
. drop two fields from minix x86 stackframe.h (process context)
that were unused, retadr and st
use in-sigframe sigcontext

Also removing lseek64, pread64, pwrite64.
Those functions have lost their "raison d'être", when off_t switched to
64bits.

This allows us to write things like this:
message m;
m.m_notify.interrupts = new_value;
or
message *mp;
mp->m_notify.interrupts = new_value;
The shorthands macro have been adapted for the new scheme, and will be
kept as long as we have generic messages being used.
Change-Id: Icfd02b5f126892b1d5d2cebe8c8fb02b180000f7
current version of <sys/stat.h> from netbsd repo is older than the minix
one; will be corrected on next netbsd re-import.
Change-Id: Ifc696581ef476cfecd9695a9f6e74b844131e584
Fix a bug where a filesystem label could overflow the reserved buffer.
This was already possible with 32 bits values, but is more proeminent
with dev_t being 64 bits.

This file was copied over to allow for the compilation of some
of the arch/i386 code, due to a bug in lib/libc/compat/Makefile.inc.
This patch fixes the situation, and removes the now useless header, as
well as remove a patch in lib/libc/stdlib/putenv.c

. create signals-related struct message type to store sigset_t
directly
. create notify-specific message types, so the generic NOTIFY_ARG
doesn't exist anymore
. various related test expansions, improvements, fixes
. add a few error-checks to sigismember() calls
. rename kernel call specific signals fields to SYS_*
Change-Id: I53c18999b5eaf0cfa0cb25f5330bee9e7ad2b478
. also implement some netbsd-style tty ioctls
. also implement SIGINFO
. also import netbsd stty
. rename keymap minix CMIN (for ctrl+minus on numeric keypad)
to CNMIN; to keep unchanged control character default CMIN in
new <sys/ttydefaults.h>
. convert CS[5678] logic in rs232 driver to explicit setting of LC
bits

changes:
. change reboot() call to netbsd prototype and args
. allows pristine <utmp.h>
. use clean <sys/reboot.h> instead of <minix/reboot.h>
. implement TIOCSCTTY for use by getty so getty can get
controlling terminal from init's child(ren)
. allow NULL envp for exec

Change-Id: I2d8ec5d061cd7e0b30c51ffd77aa72ebf84e2565
The getsysinfo(2), getrusage(2), and svrctl(2) calls used the same
call number to different services. Since we want to give each service
its own call number ranges, this is no longer tenable. This patch
introduces per-service call numbers for these calls.
Note that the remainder of the COMMON_ range is left intact, as these
the remaining requests in it are processed by SEF and thus server-
agnostic. The range should really be prefixed with SEF_ now.
Change-Id: I80d728bbeb98227359c525494c433965b40fefc3
NetBSD libc implements these as wrappers around setitimer(2),
sigsuspend(2), and getrusage(2), respectively.

. add all sys/sys headers not already present to help compiling
. take netbsd dirent.h and struct dirent; main result is
introducing d_type and d_namlen that have to be set by getdents()
in all FS code implementing it
. d_off is gone
. alignment of the struct has become 8 bytes instead of 4
. remove _MAX_BLOCK_SIZE, _MIN_BLOCK_SIZE, _STATIC_BLOCK_SIZE
. libminlib: cleanup unused yet duplicate code
. mfs: throw out the long-broken v1, v2 support

- change all sync char drivers into async drivers;
- retire support for the sync protocol in libchardev;
- remove async dev style, as this is now the default;
- remove dev_status from VFS;
- clean up now-unused protocol messages.

* Removed startup code patches in lib/csu regarding kernel to userland
ABI.
* Aligned stack layout on NetBSD stack layout.
* Generate valid stack pointers instead of offsets by taking into account
_minix_kerninfo->kinfo->user_sp.
* Refactored stack generation, by moving part of execve in two
functions {minix_stack_params(), minix_stack_fill()} and using them
in execve(), rs and vm.
* Changed load offset of rtld (ld.so) to:
execi.args.stack_high - execi.args.stack_size - 0xa00000
which is 10MB below the main executable stack.

- pass in file system type through mount(2), and return this type in
statvfs structures as generated by [f]statvfs(2);
- align mount flags field with NetBSD's, splitting out service flags
which are not to be passed to VFS;
- remove limitation of mount ABI to 16-byte labels, so that labels
can be made larger in the future;
- introduce new m11 message union type for mount(2) as side effect.
