This fixes the bug that caused BUG_ON(!irqs_disabled()) to trigger in
run_posix_cpu_timers() on alpha/smp. We didn't disable interrupts
properly before calling smp_percpu_timer_interrupt().
We *do* disable interrupts everywhere except this unfortunate
smp_percpu_timer_interrupt(). Fixed thus.

As usual, the reason of this breakage is quite silly: in do_entIF, we
are checking for PS == 0 to see whether it was a kernel BUG() or
userspace trap.
It works, unless BUG() happens in interrupt - PS is not 0 in kernel mode
due to non-zero IPL, and the things get messed up horribly then. In
this particular case it was BUG_ON(!irqs_disabled()) triggered in
run_posix_cpu_timers(), so we ended up shooting "current" with the
bursts of one SIGTRAP and three SIGILLs on every timer tick. ;-)

On system boot up, there was an failure reported to boot.msg:
<5>Trying to move old root to /initrd ... failed
According to initrd(4) man page, step #7 of BOOT-UP OPERATION
is described as below:
7. If the normal root file has directory /initrd, device
/dev/ram0 is moved from / to /initrd. Otherwise if
directory /initrd does not exist device /dev/ram0 is
unmounted.
We got service calls from customers concerning about this failure message
at boot time. Many systems do not have /initrd and thus the message can be
changed in the case of non-existing /initrd so that it does not sound like
a failure of the system.

Currently selinux_sb_copy_data requires an entire page be allocated to
*orig when the function is called. This "requirement" is based on the fact
that we call copy_page(in_save, nosec_save) and in_save = orig when the
data is not FS_BINARY_MOUNTDATA. This means that if a caller were to call
do_kern_mount with only about 10 bytes of options, they would get passed
here and then we would corrupt PAGE_SIZE - 10 bytes of memory (with all
zeros.)
Currently it appears all in kernel FS's use one page of data so this has
not been a problem. An out of kernel FS did just what is described above
and it would almost always panic shortly after they tried to mount. From
looking else where in the kernel it is obvious that this string of data
must always be null terminated. (See example in do_mount where it always
zeros the last byte.) Thus I suggest we use strcpy in place of copy_page.
In this way we make sure the amount we copy is always less than or equal to
the amount we received and since do_mount is zeroing the last byte this
should be safe for all.
