Create a new header lwp_private.h to contain _lwp_getprivate_fast,
_lwp_gettcb_fast, _lwp_settcb and remove them from mcontext.h, so that:
1. we don't need special hacks to hide them
2. we can include <lwp.h> where needed to get the necessary prototypes
without redefining them locally.

Add acpi_intr_mask() and acpi_intr_unmask() which, following the pre-existing
ACPI software layering model, are wrappers around acpi_md_intr_mask() and
acpi_md_intr_unmask(), which in turn are wrappers around intr_mask() and
intr_unmask().

Allow registering ACPI interrupt handlers with a xname.
AcpiOsInstallInterruptHandler(), part of ACPICA API, doesn't allow passing
the xname. I extend the API with AcpiOsInstallInterruptHandler_xname()
for this purpose, and change acpi_md_OsInstallInterruptHandler() to
accept and use the xname (ia64 doens't use it).
The xname was hardcoded to "acpi SCI" in the
x86 acpi_md_OsInstallInterruptHandler(), so I make
AcpiOsInstallInterruptHandler() call
AcpiOsInstallInterruptHandler_xname with xname = "acpi SCI".

Now 'vmstat -i' shows the device's name instead of "acpi SCI" for for i2c HID
interrupts.

Should fix PR port-amd64/42895, possibly also PR kern/42583, and many
other comparable bugs.

A common sense explanation is that Intel supplies additional CPU tables to
OEMs. BIOS writers do not bother to modify their DSDTs, but instead load
these extra tables dynamically as secondary SSDT tables. The actual Load()
happens when the _PDC method is invoked, and thus namespace errors occur
when the CPU-specific ACPI methods are not yet present but referenced in the
AML by various drivers, including, but not limited to, acpitz(4).

Add getlabelusesmbr(), as proposed in
http://mail-index.netbsd.org/tech-userlevel/2011/08/25/msg005404.html
This is used by disk tools such as disklabel(8) to dynamically decide is
the undelyling platform uses a disklabel-in-mbr-partition or not
(instead of using a compile-time list of ports).
getlabelusesmbr() reads the sysctl kern.labelusesmbr, takes its value from the
machdep #define LABELUSESMBR.
For evbmips, make LABELUSESMBR 1 if the platform uses pmon
as bootloader, and 0 (the previous value) otherwise.

If cpu_disklabel includes struct dkbad, define __HAVE_DISKLABEL_DKBAD.
This allows use of subr_disk_mbr on all archs. Default to it for
the rump disk component. No functional change for regular kernels.
(The other option would've been to include dkbad in disklabels
everywhere, but arguably this approach has less possible side-effects,
especially given that wedges and related magic will take over the
world any second now).

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

Fix definitions of UCHAR_MAX/USHRT_MAX and related
types. C99 requires that these definitions promote to (signed/unsigned)

unsigned char/short fit into an "int" on all our archs and thus promote
to signed int, the definitions must not be unsigned.

__cpu_simple_lock(9): Omit needless barriers in init.

It is, and always has been, the caller's responsibility to ensure the
lock is initialized before it can be used -- otherwise the memory
could hold garbage; it is nonsensical to even attempt locking
operations on it before initialization.

So there's no need to issue explicit barriers here. The barrier
seems to have been introduced in sys/arch/alpha/alpha/lock_machdep.c
rev. 1.1 (since moved to inline asm in alpha/include/lock.h) and then
copied & pasted into several other architectures.

This fixes a build problem in src/tests/lib/libc/sys/t_ucontext.c.

This needs to be revisited once the port will get more mature.

Introduce _UC_MACHINE_FP() as a macro

_UC_MACHINE_FP() is a helper macro to extract from mcontext a frame pointer.

Don't rely on this interface as a compiler might strip frame pointer or
optimize it making this interface unreliable.


For hppa assume a small frame context, for larger frames FP might be located
in a different register (4 instead of 3).

For ia64 there is no strict frame pointer, and registers might rotate.
Reuse 79 following:

./gcc/config/ia64/ia64.h:#define HARD_FRAME_POINTER_REGNUM LOC_REG (79)

Once ia64 will mature, this should be revisited.

A macro can encapsulate a real function for extracting Frame Pointer on
more complex CPUs / ABIs.


For the remaining CPUs, reuse standard register as defined in appropriate ABI.

The direct users of this macro are LLVM and GCC with Sanitizers.

No functional change intended.

- In kern_mutex.c, if MUTEX_CAS() is not defined, define it in terms of

- For arm, ia64, m68k, mips, or1k, riscv, vax: don't define our own
MUTEX_CAS(), as they either use atomic_cas_ulong() or equivalent
(atomic_cas_uint() on m68k).
- For alpha and sparc64, don't define MUTEX_CAS() in terms of their own
_lock_cas(), which has its own memory barriers; the call sites in
kern_mutex.c already have the appropriate memory barrier calls. Thus,
alpha and sparc64 can use default definition.
- For sh3, don't define MUTEX_CAS() in terms of its own _lock_cas();
atomic_cas_ulong() is strong-aliased to _lock_cas(), therefore defining
our own MUTEX_CAS() is redundant.

Make pmap_kernel() a MI macro for struct pmap *kernel_pmap_ptr,

Introduce PTRACE_REG_FP() a helper macro to retrieve the frame pointer

branches: 1.4.14;
Add new ptrace(2) API: PT_SETSTEP & PT_CLEARSTEP

These operations allow to mark thread as a single-stepping one.

This allows to i.a.:
- single step and emit a signal (PT_SETSTEP & PT_CONTINUE)
- single step and trace syscall entry and exit (PT_SETSTEP & PT_SYSCALL)

The former is useful for debuggers like GDB or LLDB. The latter can be used
to singlestep a usermode kernel. These examples don't limit use-cases of
this interface.

Define PT_*STEP only for platforms defining PT_STEP.

Add new ATF tests setstep[1234].

These ptrace(2) operations first appeared in FreeBSD.

Remove the kernel PMC code. Sent yesterday on tech-kern@.

This change:

* Removes "options PERFCTRS", the associated includes, and the associated
ifdefs. In doing so, it removes several XXXSMPs in the MI code, which is
good.

* Removes the PMC code of ARM XSCALE.

* Removes all the pmc.h files. They were all empty, except for ARM XSCALE.

* Reorders the x86 PMC code not to rely on the legacy pmc.h file. The
definitions are put in sysarch.h.

* Removes the kern/sys_pmc.c file, and along with it, the sys_pmc_control
and sys_pmc_get_info syscalls. They are marked as OBSOL in kern,
netbsd32 and rump.

* Removes the pmc_evid_t and pmc_ctr_t types.

* Removes all the associated man pages. The sets are marked as obsolete.

expose the kernel types for standalone code.

Hide {p,v}{addr,size}_t and register_t (and a couple more types that
are machine-specific) from userland unless _KERNEL/_KMEMUSER and a
new _KERNTYPES variables is defined. The _KERNTYPES should be fixed
for many subsystems that should not be using it (rump)...

Fix PTHREAD_FOO_INITIALIZER for C++ by not using volatile in the relevant
pthread types in C++ builds, attempt 2.

The problem with attempt 1 was making assumptions of what the MD
__cpu_simple_lock_t (declared volatile) looks like. To get a same type
except non-volatile, we change the MD type to __cpu_simple_lock_nv_t
and typedef __cpu_simple_lock_t as a volatile __cpu_simple_lock_nv_t.
IMO, __cpu_simple_lock_t should not be volatile at all, but changing it
now is too risky.

Fixes at least Rumprun w/ gcc 5.1/5.2. Furthermore, the mpd application
(and possibly others) will no longer require NetBSD-specific patches.

Tested: build.sh for i386, Rumprun for x86_64 w/ gcc 5.2.
