Merge branch 'fix-stack-noinline' into refs/top-bases/fix-branch

Add fix-stack-noinline topic branch

Certain function must never be automatically inlined by gcc because
they are stack heavy or called recursively.  This patch flags all
such functions I have found as 'noinline' to prevent gcc from making
the optimization.

Merge branch 'fix-stack' into refs/top-bases/fix-branch

Revert fix-stack topic branch

This patch will be broken in to several independent stack reductions
and reapplied as new topic branches.

Merge branch 'fix-stack-dsl_deleg_get' into refs/top-bases/fix-branch

Add fix-stack-dsl_deleg_get topic branch

Reduce stack usage in dsl_deleg_get, gcc flagged it as consuming a
whopping 1040 bytes or potentially 1/4 of a 4K stack.  This patch
moves all the large structures and buffer off the stack and on to
the heap.  This includes 2 zap_cursor_t structs each 52 bytes in
size, 2 zap_attribute_t structs each 280 bytes in size, and 1
256 byte char array.  The total saves on the stack is 880 bytes
after you account for the 5 new pointers added.

Also the source buffer length has been increased from MAXNAMELEN
to MAXNAMELEN+strlen(MOS_DIR_NAME)+1 as described by the comment in
dsl_dir_name().  A buffer overrun may have been possible with the
slightly smaller buffer.

Merge branch 'fix-stack-dsl_dir_open_spa' into refs/top-bases/fix-branch

Add fix-stack-dsl_dir_open_spa topic branch

Reduce stack usage by 256 bytes by moving buf char array from
the stack to the heap.

Merge branch 'fix-stack-lzjb' into refs/top-bases/fix-branch

Add fix-stack-lzjb topic branch

Reduce kernel stack usage by lzjb_compress() by moving uint16 array
off the stack and on to the heap.  The exact performance implications
of this I have not measured but we absolutely need to keep stack
usage to a minimum.  If/when this becomes and issue we optimize.

Merge branch 'fix-kstat-xuio' into refs/top-bases/fix-branch

Add fix-kstat-xuio topic branch

Move xiou stat structures from a header to the dmu.c source as is
done with all the other kstat interfaces.  This information is local
to dmu.c registered the xuio kstat and should stay that way.

Merge branch 'fix-metaslab' into refs/top-bases/fix-branch

Add fix-metaslab topic branch

If your only going to allow one allocator to be used and it is defined
at compile time there is no point including the others in the build.
This patch could/should be refined for Linux to make the metaslab
configurable at run time.  That might be a bit tricky however since
you would need to quiese all IO.  Short of that making it configurable
as a module load option would be a reasonable compromise.

Merge branch 'fix-current' into refs/top-bases/fix-branch

Add fix-current topic branch

In the linux kernel 'current' is defined to mean the current process
and can never be used as a local variable in a function.  Simply
replace all usage of 'current' with 'curr' in this function.

Merge branch 'fix-pthreads' into refs/top-bases/fix-branch

Merge branch 'fix-taskq' into refs/top-bases/fix-branch

Add fix-pthreads topic branch

This is a portability change which removes the dependence of the Solaris
thread library.  All locations where Solaris thread API was used before
have been replaced with equivilant Solaris kernel style thread calls.
In user space the kernel style threading API is implemented in term of
the portable pthreads library.  This includes all threads, mutexs,
condition variables, reader/writer locks, and taskqs.

Update fix-taskq to never sleep at interrupt time

Updated fix to detect if we are in an interrupt and only sleep if it
is safe to do some.  I guess it must be safe to sleep under Solaris
this must be handled in a sort interrupt handler there
