5bc7afa9ee A previous change moved the GETATTR RPC for open() calls that hit in the
name cache up into nfs_lookup() instead of nfs_open().  Continue this
trend by flushing the attribute cache for leaf nodes in nfs_lookup() during
an open() if we do a LOOKUP RPC.  For NFSv3 this should generally be a NOP
as the attributes are flushed before fetching the post-op attributes from
the LOOKUP RPC which most (all?) NFSv3 servers provide, so the post-op
attributes should populate the cache.

Now all NFS open() calls will always clear the cached attributes during the
nfs_lookup() prior to nfs_open() in the !NMODIFIED case to provide CTOC.
As a result, we can remove the conditional flushing of the attribute
cache from nfs_open().

60fbea5ce0 Revert and remake r209883:
Do not grab lock while setting up interrupt, as it causes LOR with
allocation code. Instead make interrupt handler check that CAM bus
initialization completed before touching it.

While there, slightly improve attach errors handling.

6496d826cc Convert Freescale PowerPC platforms to FDT convention.
The following systems are affected:

  - MPC8555CDS
  - MPC8572DS

This overhaul covers the following major changes:

  - All integrated peripherals drivers for Freescale MPC85XX SoC, which are
    currently in the FreeBSD source tree are reworked and adjusted so they
    derive config data out of the device tree blob (instead of hard coded /
    tabelarized values).

  - This includes: LBC, PCI / PCI-Express, I2C, DS1553, OpenPIC, TSEC, SEC,
    QUICC, UART, CFI.

  - Thanks to the common FDT infrastrucutre (fdtbus, simplebus) we retire
    ocpbus(4) driver, which was based on hard-coded config data.

Note that world for these platforms has to be built WITH_FDT.

d760bd51fb Remove interval validation from cpu_tick_calibrate(). As I found, check
was needed at preliminary version of the patch, where number of CPU ticks
was divided strictly on 16 seconds. Final code instead uses real interval
duration, so precise interval should not be important. Same time aliasing
issues around second boundary causes false positives, periodically logging
useless "t_delta ... too long/short" messages when HZ set below 256.

0a0ebaf177 Reduce the number of global TLB shootdowns generated by pmap_qenter().
Specifically, teach pmap_qenter() to recognize the case when it is being
asked to replace a mapping with the very same mapping and not generate
a shootdown.  Unfortunately, the buffer cache commonly passes an entire
buffer to pmap_qenter() when only a subset of the mappings are changing.
For the extension of buffers in allocbuf() this was resulting in
unnecessary shootdowns.  The addition of new pages to the end of the
buffer need not and did not trigger a shootdown, but overwriting the
initial mappings with the very same mappings was seen as a change that
necessitated a shootdown.  With this change, that is no longer so.

For a "buildworld" on amd64, this change eliminates 14-15% of the
pmap_invalidate_range() shootdowns, and about 4% of the overall
shootdowns.

615d4b84bc RTLD support for powerpc64. A few small modifications to the Makefile
and symbol map are required to support various consequences of the dot
symbol scheme:

- Symbols beginning with a dot are reserved, so start private symbols with
  an underscore.
- In order to set RTLD breakpoints, gdb must be able to locate the text
  entry point, not the data section function descriptor, so add
  .r_debug_state to the symbol map on powerpc64.

d1c3838436 The 64-bit PowerPC ABI implemented in binutils 2.15 requires some special
quirks for weak-symbol handling. Text symbols require also marking weak
the special dot-symbol associated with the function, and data symbols
require that you not do that. To fix this, provide a hacked
__weak_reference for powerpc64, and define a new __weak_reference_data
for the single weak data symbol in base.
