46a0387a46 CCACHE_BUILD: Don't use ccache when generating some files with CC -E.
At least for ncurses this fixes a build error due to it trying to run
'ccache --version' to work around a gcc 5 bug using the fix in r287205.

1f3bbfd875 Replace the CloudABI system call table by a machine generated version.
The type definitions and constants that were used by COMPAT_CLOUDABI64
are a literal copy of some headers stored inside of CloudABI's C
library, cloudlibc. What is annoying is that we can't make use of
cloudlibc's system call list, as the format is completely different and
doesn't provide enough information. It had to be synced in manually.

We recently decided to solve this (and some other problems) by moving
the ABI definitions into a separate file:

	https://github.com/NuxiNL/cloudabi/blob/master/cloudabi.txt

This file is processed by a pile of Python scripts to generate the
header files like before, documentation (markdown), but in our case more
importantly: a FreeBSD system call table.

This change discards the old files in sys/contrib/cloudabi and replaces
them by the latest copies, which requires some minor changes here and
there. Because cloudabi.txt also enforces consistent names of the system
call arguments, we have to patch up a small number of system call
implementations to use the new argument names.

The new header files can also be included directly in FreeBSD kernel
space without needing any includes/defines, so we can now remove
cloudabi_syscalldefs.h and cloudabi64_syscalldefs.h. Patch up the
sources to include the definitions directly from sys/contrib/cloudabi
instead.

1d640d3b42 Pull in r264335 from upstream llvm trunk:
Add <atomic> to ThreadPool.h, since std::atomic is used

  Summary:
  Apparently, when compiling with gcc 5.3.2 for powerpc64, the order of
  headers is such that it gets an error about std::atomic<> use in
  ThreadPool.h, since this header is not included explicitly.  See also:

  https://llvm.org/bugs/show_bug.cgi?id=27058

  Fix this by including <atomic>.  Patch by Bryan Drewery.

676e25ab0f elfcopy: overhaul of LMA handling
Merge ELF Tool Chain r3434:

    Previously, elfcopy defines:

    VMA:  section virtual address
    LMA:  PHDR(p_vaddr)

    While binutils(libbfd) defines:

    VMA:  section virtual address and PHDR(p_vaddr).
    LMA:  PHDR(p_paddr)

    For elfcopy, p_paddr is considered not meaningful and is always set
    to the same value as p_vaddr.

    elfcopy was implemented that way because I thought p_paddr is not
    used/meaningful according to the ELF ABI. However it turned out
    p_paddr is at least used in some ELF files, e.g. the FreeBSD kernel.

    This change made elfcopy treat p_paddr as LMA, same as libbfd.

    (However, some VMA/LMA related command line option still need tweaking
    to make them compatible with binutils objcopy. This will be improved
    later)

    Ticket: #524

And typo fixes in r3435 and r3436.

This fixes the Xen kernel build.

61c8fde5d6 Generalize IPI support for ARM intrng and use it for interrupt
controller IPI provider.

New struct intr_ipi is defined which keeps all info about an IPI:
its name, counter, send and dispatch methods. Generic intr_ipi_setup(),
intr_ipi_send() and intr_ipi_dispatch() functions are implemented.

An IPI provider must implement two functions:
(1) an intr_ipi_send_t function which is able to send an IPI,
(2) a setup function which initializes itself for an IPI and
    calls intr_ipi_setup() with appropriate arguments.

25a40f12b0 hyperv/vmbus: use a better retry method in hv_vmbus_post_message()
Most often, hv_vmbus_post_message() doesn't fail.  However, it fails
intermittently when GPADLs of large shared memory is to be established
with the host, e.g. on the hn(4) attach path: a GPADL of 15MB sendbuf
is created, for which lots of messages will be flooded to the host.
The host side tries to throttle the message rate by returning
HV_STATUS_INSUFFICIENT_BUFFERS.

Before this commit, we do several retries for failed messages, but the
delay between each retry is pretty/too low, which will cause sporadic
message posting failure.  We now use large delay (>=1ms) between each
retry to fix the message posting failure.

7a2c1d8c60 Enable interrupts on the BSP once all PICs are initialized.
This moves the enabling of interrupts slightly earlier (the old location
was still before devices were enumerated and probed) and does it in the

also avoids tripping over an assertion on the first TLB shootdown with

5d20f97461 to_flags is currently a 64-bit integer; however, we only use 7 bits.
Furthermore, there is no reason this needs to be a 64-bit integer
for the forseeable future.

Also, there is an inconsistency between to_flags and the mask in
tcp_addoptions(). Before r195654, to_flags was a u_long and the mask in
tcp_addoptions() was a u_int. r195654 changed to_flags to be a u_int64_t
but left the mask in tcp_addoptions() as a u_int, meaning that these
variables will only be the same width on platforms with 64-bit integers.

Convert both to_flags and the mask in tcp_addoptions() to be explicitly
32-bit variables. This may save a few cycles on 32-bit platforms, and
avoids unnecessarily mixing types.

The mbuf provider is made up of a set of Statically Defined Tracepoints
which help us look into mbufs as they are allocated and freed.  This can be

New tracepoints are:

mbuf:::m-init
mbuf:::m-gethdr
mbuf:::m-get
mbuf:::m-getcl
mbuf:::m-clget
mbuf:::m-cljget
mbuf:::m-cljset
mbuf:::m-free
mbuf:::m-freem

There is also a translator for mbufs which gives some visibility into the structure,
see mbuf.d for more details.
