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.

8de20561d1 Fixes a bug for LP PHY that some frames have 2 padding bytes at the
start so we should adjust the mbuf if the driver is running in PIO mode.
Now it should work well with WPA authentication and association for LP

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.

798f7ab69e Some revision of Yukon controller generates corrupted frame when TX
checksum offloading is enabled.  The frame has a valid checksum
value so payload might be modified during TX checksum calculation.
Disable TX checksum offloading but give users chance to enable it
when they know their controller works without problems with TX
checksum offloading.

5e9badadaf For both i386 and amd64 pmap,
- change the type of pm_active to cpumask_t, which it is;
- in pmap_remove_pages(), compare with PCPU(curpmap), instead of
  dereferencing the long chain of pointers [1].
For amd64 pmap, remove the unneeded checks for validity of curpmap
in pmap_activate(), since curpmap should be always valid after
r209789.

7c09dc242c Add support for the VM_ALLOC_COUNT() hint to vm_page_alloc(). Consequently,
the maintenance of vm_pageout_deficit can be localized to just two places:
vm_page_alloc() and vm_pageout_scan().

This change also corrects an off-by-one error in the maintenance of
vm_pageout_deficit.  Historically, the buffer cache functions, allocbuf()
and vm_hold_load_pages(), have not taken into account that vm_page_alloc()
already increments vm_pageout_deficit by one.

ad7dfe8fd7 Improve cxgb(4)'s behaviour when faced with temporarily "bouncy" links:
- Run the adapter's tick at 1Hz and remove link state checks from it.
  Instead, have each port check its link state.  Delay the check so that
  it takes place slightly after the driver is notified of a change in
  link state.  This is a cheap way to debounce these notifications if
  many are received in rapid succession.  POLL_LINK_1ST_TIME flag can
  also be eliminated as a side effect of these changes.
- Do not reset the PHY when link goes down.
- Clear port's link_fault flag if the PHY indicates link is down.
- get_link_status_r should leave speed and duplex alone when link is down.

0fac9c7272 Sync. printf() of libstand(3) with sys/kern/subr_prf.c.
CVS r1.94	jhb:
Cast the integer read as the first argument for %b to an unsigned integer
so it's value is not sign extended when assigned to the uintmax_t variable
used internally by printf.  For example, if bit 31 is set in the cpuid
feature word, then %b would print out the initial value as a 16 character
hexadecimal value.  Now it only prints out an 8 character value.

CVS r1.109	njl:
Add support for 'h' and 'hh' modifiers for printf(9).

CVS r1.117	phk:
If we ignore an unknown % sequence, we must stop interpreting the remaining
% arguments because the varargs are now out of sync and there is a risk that
we might for instance dereference an integer in a %s argument.
