4066649d5a Backed out the micro-optimization in 1.4. It was to help gcc-2.6.3 
on i486's (and probably i386's), but it has had very little effect
since gcc-2.7 or gcc-2.95.  With gcc-3.3, it gave a small
pessimization for at least i386's, athlon-xp's and pentium4's, a
small optimization (I think) for pentium1's, and made no difference
for i386's.  (movzbl is best for all the later processors, and the
micro-optimization was to stop it being used on i486's.)

853af3f3f0 o Do not overwrite saved interrupt priority level by alloc_hash(), 
use a separate variable.
o Restore interrupt priority level before return (no-op in HEAD).

c1e97bb458 Remove __aligned(16) from the definition of struct _ia64_fpreg. It's 
a non-standard construct. Instead, redefine struct _ia64_fpreg as a
union and put a long double in it. On ia64 and for LP64, this is
defined by the ABI to have 16-byte alignment. For ILP32 a long double
has 4-byte alignment, but we don't support ILP32.

Note that the in-memory image of a long double does not match the in-
memory image of spilled FP registers. This means that one cannot use
the fpr_flt field to interpet the bits. For this reason we continue
to use an aggregate type.

9b18b1f47d Hand the packet to bpf not only in the LLC/SNAP case, but for all 
connections. While this confuses tcpdump, it enables other applications
to see and analyze non-IP traffic (signalling, for example).

2a51529f7e Provide a knob for raising the inline instruction estimate threshold and 
set an initial value.  This is aimed at getting us closer to being able to
turn -Werror back on and we can adjust the settings later on.  Yes, we
could turn off -Wno-inline instead, but that would hide the effect of
gcc's bogo-estimator ignoring inline (either rightly or wrongly).

3462150083 Annotate pmap_changebit() as __always_inline. This function was 
written as a template that when inlined is specialized for the caller
through constant value propagation and dead code elimination.  Thus,
the specialized code that is generated for pmap_clear_reference() et
al. avoids several conditional branches inside of a loop.

793e17ba11 We sloppily created an array for the high FP registers (f32-f127), 
but this just created a weird inconsistency when porting gdb(1).
Instead, we name each high FP register seperately, like we do for
all the other registers.

a33f5caff3 Attempt to preempt any new gcc-ism references to
