ba8c50ff8b For kvm-based kernhist code, print size of history table and "next free" 
pointer, same as we do for sysctl-based code.

6a4fc5e568 Restore the kvm-grovelling code for use on crash files (where sysctl(3) 
is not available).  Otherwise, this would always report on the current
running kernel regardless of the use of -M option.

93058c7f3d For kernel history display, replace the kvm grovelling with the newly 
available sysctl access to the history data.

XXX vmstat still uses kvm for several other displays

bb762fe5ee No point in using float here; makes evbmips64 need __truncdfsf2, and that 
causes static linking issues because of softfloat.

7ad3371ebc Update stats-keeping in sys/kern/vfs_cache.c to remove (most) 
races while allowing consistent lockless sampling of the per-cpu
statistics without atomic operations.  Update comment describing
the locking protocol to include this.

These files were fumble-fingered out of the last commit.

42c8d67c49 Add a global vnode cache: 
- vcache_get() retrieves a referenced and initialised vnode / fs node pair.
- vcache_remove() removes a vnode / fs node pair from the cache.

On cache miss vcache_get() calls new vfs operation vfs_loadvnode() to
initialise a vnode / fs node pair.  This call is guaranteed exclusive,
no other thread will try to load this vnode / fs node pair.

Convert ufs/ext2fs, ufs/ffs and ufs/mfs to use this interface.

Remove now unused ufs/ufs_ihash

Discussed on tech-kern.

a216da57a6 Default to -Wno-sign-compare -Wno-pointer-sign for clang. 
Push -Wno-array-bounds down to the cases that depend on it.
Selectively disable warnings for 3rd party software or non-trivial
issues to be reviewed later to get clang -Werror to build most of the
tree.

8169e46991 move and rename the uvm history code out of uvm_stat to "kernhist". 
rename "UVMHIST" option to enable the uvm histories.

TODO:
- make UVMHIST properly depend upon KERNHIST
- enable dynamic registration of histories.  this is mostly just
  allocating something in a bitmap, and is only for viewing multiple
  histories in a merged form.


tested on amd64 and sparc64.

45362e3914 Defer nlist processing until we know we need to it. If everything can be 
obtained via sysctl, we can skip it entirely.  This means we can run even
if not setgid.

getuptime will now use sysctl/clock_gettime if memf is NULL.
doevcnt now sues sysctl(kern.evcnt) is memf is NULL.  It falls back to
groveling if sysctl returns an error of ENOENT.
dointr will call doevcnt to evcnt based intr stats.

fdbe2a0785 can't play games with structure names since cpu_data refers to cpu_info, so
