Ray Lee reported, that on an UP kernel with "noapic" command line option
set, the box locks hard during boot.

Adding some debug printks revealed, that the last action on the box
before stalling was "Send IPI" - a debug printk which was put into
smp_send_timer_broadcast_ipi().

It seems that send_IPI_mask(mask, LOCAL_TIMER_VECTOR) fails when
"noapic" is set on the command line on an UP kernel.

Aside of that it does not make much sense to trigger an interrupt
instead of calling the function directly on the CPU which gets the
PIT/HPET interrupt in case of broadcasting.

The segment register slots in struct pt_regs are padded to 32 bits.
Some of these are stored with instructions like "pushl %es", which
leaves the high 16 bits as they were.  So the high bits of these
fields in struct pt_regs contain kernel stack garbage.  These bits are
ignored by everything and never leak to user space, except in core
dumps.  The user struct pt_regs is always at the base of the thread's
kernel stack and so it seems unlikely the information that leaks from
here is ever worthwhile so as to be a security concern, but I'm not
sure about that.  It has been this way for ages; userland consumers of
core dumps all mask off these high bits themselves.  So it is not urgent.

This change masks off the padding bits of the segment register slots
in core dumps.  ptrace already masks off these high bits, so this
makes the values in core dumps consistent with what ptrace would
report just before the process died.

As I read the processor manuals, the cs and ss values will always be
padded with zero bits rather than stack garbage.  But unlike "pushl %es",
this is not simple to test with a userland program.  So I added the two
instructions rather than wonder if they are really never necessary.

I think that x86_64 does not have this problem (for either 32-bit or
64-bit processes).  It only uses "mov" instructions from segment
registers, which zero-extend.

Fix the /proc/pid/stat representation of executable boundaries.  It should
show the bounds of the executable, but instead shows the bounds of the
loader.

Before the patch is applied, the bug can be seen by examining, say, inetd:

	# ps | grep inetd
	  610         root          0   S   /usr/sbin/inetd -i
	# cat /proc/610/maps

 	3273467584 0 0 4096 90115 3221712796 0 0 17 0 0 0 0

The code boundaries are 3233480704 to 3233523592, which are:

	(gdb) p/x 3233480704
	$1 = 0xc0bb0000
	(gdb) p/x 3233523592
	$2 = 0xc0bba788

Which corresponds to this line in the maps file:

	c0bb0000-c0bba788 r-xs 00000000 00:0b 14582157  /lib/ld-uClibc-0.9.28.so

Which is wrong.  After the patch is applied, the maps file is pretty much
identical (there's some minor shuffling of the location of some of the
anonymous VMAs), but the stat file is now:

	# cat /proc/610/stat
	610 (inetd) S 1 610 610 0 -1 256 0 0 0 0 0 7 0 0 18 0 1 0 94392000722
	950272 0 4294967295 3276111872 3276141668 3274440352 3274439976
	3273467584 0 0 4096 90115 3221712796 0 0 17 0 0 0 0

The code boundaries are then 3276111872 to 3276141668, which are:

	(gdb) p/x 3276111872
	$1 = 0xc3458000
	(gdb) p/x 3276141668
	$2 = 0xc345f464

And these correspond to this line in the maps file instead:

	c3458000-c345f464 r-xs 00000000 00:0b 16384612  /usr/sbin/inetd

Which is now correct.

It turned out that it is almost impossible to trust ACPI, BIOS & Co.

Allow the user to confirm that the local apic timer is trustworthy in C2
