9aca3e0f2b Clang's 3.5 integrated assembler now handles these files correctly (it
has support for the .codeXX directives). However, it is desirable, for
a time, to allow kernels to be built with clang 3.4. Historically, it
has been advantageous to allow stable X-1 to build kernels the old
way (so long as the impact of doing so is small), and this restores
that ability.

Also, centralize the addition of ${ASM_CFLAGS.${.IMPSRC}}, place it in
kern.mk rather than kern.pre.mk so that all modules can benefit, and
give the same treatment to CFLAGS in kern.mk as well.

ab2de2d795 Bump the version of config to the latest (3 year old, so upgrade
worries are long past). Also remove redundant MACHINE= declarations
and passing MACHINE/MACHINE_ARCH to module builds. That's now done in
common code.

cb34ed4434 Add basic support for FDT to i386 & amd64. This change includes:
1.  Common headers for fdt.h and ofw_machdep.h under x86/include
    with indirections under i386/include and amd64/include.
2.  New modinfo for loader provided FDT blob.
3.  Common x86_init_fdt() called from hammer_time() on amd64 and
    init386() on i386.
4.  Split-off FDT specific low-level console functions from FDT
    bus methods for the uart(4) driver. The low-level console
    logic has been moved to uart_cpu_fdt.c and is used for arm,
    mips & powerpc only. The FDT bus methods are shared across
    all architectures.
5.  Add dev/fdt/fdt_x86.c to hold the fdt_fixup_table[] and the
    fdt_pic_table[] arrays. Both are empty right now.

FDT addresses are I/O ports on x86. Since the core FDT code does
not handle different address spaces, adding support for both I/O
ports and memory addresses requires some thought and discussion.
It may be better to use a compile-time option that controls this.

07b202a847 Define several extra macros in bsd.sys.mk and sys/conf/kern.pre.mk, to
get rid of testing explicitly for clang (using ${CC:T:Mclang}) in
individual Makefiles.

Instead, use the following extra macros, for use with clang:
- NO_WERROR.clang       (disables -Werror)
- NO_WCAST_ALIGN.clang  (disables -Wcast-align)
- NO_WFORMAT.clang	(disables -Wformat and friends)
- CLANG_NO_IAS		(disables integrated assembler)
- CLANG_OPT_SMALL	(adds flags for extra small size optimizations)

As a side effect, this enables setting CC/CXX/CPP in src.conf instead of
make.conf!  For clang, use the following:

CC=clang
CXX=clang++
CPP=clang-cpp

9e2f7513e1 Bump config(8) version and build requirement for config(8) to 600006. This
is caused by my latest changes to config(8). You're supposed to install new
config(8) in order to prevent yourself from seeing a warning about old

You should configure the kernel with a new config(8) then.

05b5ca733b We don't bump the config version for additions to config that aren't
used in the base system.  This has been much discussed in the past
(typically people giving me a hard time for it).  Since all that was
added to config was nocpu, and since we don't use it, we don't need to
bump the version.

f0c1dee27f The latest release of the FreeBSD driver (twa) for
3ware's 9xxx series controllers.  This corresponds to
the 9.2 release (for FreeBSD 5.2.1) on the 3ware website.

Highlights of this release are:

1. The driver has been re-architected to use a "Common Layer"
    (all tw_cl* files), which is a consolidation of all OS-independent
    parts of the driver.  The FreeBSD OS specific portions of the
    driver go into an "OS Layer" (all tw_osl* files).
    This re-architecture is to achieve better maintainability, consistency
    of behavior across OS's, and better portability to new OS's (drivers
    for new OS's can be written by just adding an OS Layer that's specific
    to the OS, by complying to a "Common Layer Programming Interface" API.

2. The driver takes advantage of multiple processors.

3. The driver has a new firmware image bundled, the new features of which
   include Online Capacity Expansion and multi-lun support, among others.
   More details about 3ware's 9.2 release can be found here:
   http://www.3ware.com/download/Escalade9000Series/9.2/9.2_Release_Notes_Web.pdf

Since the Common Layer is used across OS's, the FreeBSD specific include
path for header files (/sys/dev/twa) is not part of the #include pre-processor
directive in any of the source files.  For being able to integrate twa into
the kernel despite this, Makefile.<arch> has been changed to add the include
path to CFLAGS.

f37a929ca1 Kill count device support from config. I've changed the last few
remaining consumers to have the count passed as an option.  This is
i4b, pc98/wdc, and coda.

Bump configvers.h from 500013 to 600000.

Remove heuristics that tried to parse "device ed5" as 5 units of the ed
device.  This broke things like the snd_emu10k1 device, which required
quotes to make it parse right.  The no-longer-needed quotes have been
removed from NOTES, GENERIC etc.  eg, I've removed the quotes from:
   device  snd_maestro
   device  "snd_maestro3"
   device  snd_mss

I believe everything will still compile and work after this.

It doesn't actually do it yet though.  This adds a flag to config so
that we can exclude certain vendor files from this even when the rest
of the kernel has it on.  make -DNO_WERROR would also bypass all of it.

f41325db5f With this commit, I hereby pronounce gensetdefs past its use-by date.
Replace the a.out emulation of 'struct linker_set' with something
a little more flexible.  <sys/linker_set.h> now provides macros for
accessing elements and completely hides the implementation.

The linker_set.h macros have been on the back burner in various
forms since 1998 and has ideas and code from Mike Smith (SET_FOREACH()),
John Polstra (ELF clue) and myself (cleaned up API and the conversion
of the rest of the kernel to use it).

The macros declare a strongly typed set.  They return elements with the
type that you declare the set with, rather than a generic void *.

For ELF, we use the magic ld symbols (__start_<setname> and
__stop_<setname>).  Thanks to Richard Henderson <rth@redhat.com> for the
trick about how to force ld to provide them for kld's.

For a.out, we use the old linker_set struct.

NOTE: the item lists are no longer null terminated.  This is why
the code impact is high in certain areas.

The runtime linker has a new method to find the linker set
boundaries depending on which backend format is in use.

linker sets are still module/kld unfriendly and should never be used
for anything that may be modular one day.
