x86: properly initialize temp insn buffer for paravirt patching
With commit
ab144f5ec64c42218a555ec1dbde6b60cf2982d6 the patching code
now collects the complete new instruction stream into a temp buffer
before finally patching in the new insns. In some cases the paravirt
patchers will choose to leave the patch site unpatched (length mismatch,
clobbers mismatch, etc).
This causes the new patching code to copy an uninitialized temp buffer,
i.e. garbage, to the callsite. Simply make sure to always initialize
the buffer with the original instruction stream. A better fix is to
audit all the patchers and return proper length so that apply_paravirt()
can skip copies when we leave the patch site untouched.

netconsole on the same nic.
This patch moves the printk's out of the spinlock protected area.

i386: Fix a couple busy loops in mach_wakecpu.h:wait_for_init_deassert()
Use cpu_relax() in the busy loops, as atomic_read() doesn't automatically
imply volatility for i386 and x86_64. x86_64 doesn't have this issue because
it open-codes the while loop in smpboot.c:smp_callin() itself that already
uses cpu_relax().
For i386, however, smpboot.c:smp_callin() calls wait_for_init_deassert()
which is buggy for mach-default and mach-es7000 cases.
[ I test-built a kernel -- smp_callin() itself got inlined in its only
callsite, smpboot.c:start_secondary() -- and the relevant piece of
code disassembles to the following:
0xc1019704 <start_secondary+12>: mov 0xc144c4c8,%eax
0xc1019709 <start_secondary+17>: test %eax,%eax
0xc101970b <start_secondary+19>: je 0xc1019709 <start_secondary+17>
init_deasserted (at 0xc144c4c8) gets fetched into %eax only once and
then we loop over the test of the stale value in the register only,
so these look like real bugs to me. With the fix below, this becomes:
0xc1019706 <start_secondary+14>: pause
0xc1019708 <start_secondary+16>: cmpl $0x0,0xc144c4c8
0xc101970f <start_secondary+23>: je 0xc1019706 <start_secondary+14>

[MATH-EMU]: Fix underflow exception reporting.
The underflow exception cases were wrong.
This is one weird area of ieee1754 handling in that the underflow
behavior changes based upon whether underflow is enabled in the trap
enable mask of the FPU control register. As a specific case the Sparc
V9 manual gives us the following description:
--------------------
If UFM = 0: Underflow occurs if a nonzero result is tiny and a
loss of accuracy occurs. Tininess may be detected
before or after rounding. Loss of accuracy may be
either a denormalization loss or an inexact result.
If UFM = 1: Underflow occurs if a nonzero result is tiny.
Tininess may be detected before or after rounding.
--------------------
What this amounts to in the packing case is if we go subnormal,
we set underflow if any of the following are true:
1) rounding sets inexact
2) we ended up rounding back up to normal (this is the case where
we set the exponent to 1 and set the fraction to zero), this
should set inexact too
3) underflow is set in FPU control register trap-enable mask
The initially discovered example was "DBL_MIN / 16.0" which
incorrectly generated an underflow. It should not, unless underflow
is set in the trap-enable mask of the FPU csr.
Another example, "0x0.0000000000001p-1022 / 16.0", should signal both
inexact and underflow. The cpu implementations and ieee1754
literature is very clear about this. This is case #2 above.
However, if underflow is set in the trap enable mask, only underflow
should be set and reported as a trap. That is handled properly by the
prioritization logic in
arch/sparc{,64}/math-emu/math.c:record_exception().
Based upon a report and test case from Jakub Jelinek.

then clobbering the relevant entry, if any. Unfortunately the PID for
the search needs to be stored in the MMUCR register, which is also
used by the TLB miss handler. Interrupts were enabled in _tlbie(), so
an interrupt between loading the MMUCR and the tlbsx could cause
incorrect search results, and thus a failure to invalide TLB entries

Although this might break as many machines as it fixes (a small number

Therefore revert to the previous state of not using extended read.

[AX25]: don't free pointers to statically allocated data
commit
8d5cf596d10d740b69b5f4bbdb54b85abf75810d started to add statically
allocated ax25_protocol's to list. However kfree() was still in place waiting
for unsuspecting ones on module removal.
Steps to reproduce:
modprobe netrom
rmmod netrom
P.S.: code would benefit greatly from list_add/list_del usage

Also, some whitespace fixes to bring this more into sync with the
