The recent 9p commit: bd238fb431f31989898423c8b6496bc8c4204a86 that
supposedly only moved files also introduced a new 9p sysctl interface
that did not properly register it's sysctl binary numbers.And since it was only for debugging clearly did not need a binary fast
path in any case. So this patch just remove the binary numbers.See Documentation/sysctl/ctl_unnumbered.txt for more details.
While I was at it I cleaned up the sysctl initializers a little as
well so there is less to read.Cc: Latchesar Ionkov

Due to index register access ordering problems, when using macros a line
like this fails (and does nothing):setCx86(CX86_CCR2, getCx86(CX86_CCR2) | 0x88);
With inlined functions this line will work as expected.
Note about a side effect: Seems on Geode GX1 based systems the
"suspend on halt power saving feature" was never enabled due to this
wrong macro expansion. With inlined functions it will be enabled, but
this will stop the TSC when the CPU runs into a HLT instruction.
Kernel output something like this:
Clocksource tsc unstable (delta = -472746897 ns)This is the 3rd version of this patch.

When a machine check or NMI occurs while multiple byte code is patched
the CPU could theoretically see an inconsistent instruction and crash.
Prevent this by temporarily disabling MCEs and returning early in the
NMI handler.Based on discussion with Mathieu Desnoyers.

Reenable kprobes and alternative patching when the kernel text is write
protected by DEBUG_RODATAAdd a general utility function to change write protected text. The new
function remaps the code using vmap to write it and takes care of CPU
synchronization. It also does CLFLUSH to make icache recovery faster.There are some limitations on when the function can be used, see the
comment.This is a newer version that also changes the paravirt_ops code.

This patch makes the i386 behave the same way that x86_64 does when a
segfault happens. A line gets printed to the kernel log so that tools
that need to check for failures can behave more uniformly between
debug.show_unhandled_signals sysctl variable to 0 (or by doing echo 0 >
/proc/sys/debug/exception-trace)Also, all of the lines being printed are now using printk_ratelimit() to
deny the ability of DoS from a local user with a program like the
following:main()
{
while (1)
if (!fork()) *(int *)0 = 0;
}This new revision also includes the fix that Andrew did which got rid of
new sysctl that was added to the system in earlier versions of this.
Also, 'show-unhandled-signals' sysctl has been renamed back to the old
'exception-trace' to avoid breakage of people's scripts.AK: Enabling by default for i386 will be likely controversal, but let's see what happens
