commit 8239c25f added an argument to our
__cpu_up() function, but didn't notice we have an extra definition for
this in asm/smp.h resulting in a compile failure.

Fix by removing the extraneous parisc definition of __cpu_up().  While
we're at it, remove the duplicated definition of smp_send_reschedule().

Author: James Bottomley <JBottomley@Parallels.com>

    [PARISC] fix PA1.1 oops on boot

Didn't quite fix the crash on boot.  It moved it from PA1.1 processors to
PA2.0 narrow kernels.  The final fix is to make sure the [id]tlb_miss_20 paths
also work.  Even on narrow systems, these paths require using the wide
instructions becuase the tlb insertion format is wide.  Fix this by
conditioning the dep[wd],z on whether we're being called from _11 or _20[w]
paths.

In certain configurations, the resulting kernel becomes too large to boot
because the linker places the long branch stubs for the merged .text section
at the very start of the image.  As a result, the initial transfer of control
jumps to an unexpected location.  Fix this by placing the head text in a
separate section so the stubs for .text are not at the start of the image.

As described in e6fa16ab ("signal: sigprocmask() should do
retarget_shared_pending()") the modification of current->blocked is
incorrect as we need to check whether the signal we're about to block is
pending in the shared queue.

Also, use the new helper function introduced in commit 5e6292c0
("signal: add block_sigmask() for adding sigmask to current->blocked")
which centralises the code for updating current->blocked after
successfully delivering a signal and reduces the amount of duplicate code
across architectures.  In the past some architectures got this code wrong,
so using this helper function should stop that from happening again.

Due to an errata, the PA7300LC generates a TLB miss interruption even on the
prefetch instruction.  This means that prefetch(NULL), which is supposed to be
a nop on linux actually generates a NULL deref fault.  Fix this by testing the
address of prefetch against NULL before doing the prefetch.

As pointed out by serveral people, PA1.1 only has a type 26 instruction
meaning that the space register must be explicitly encoded.  Not giving an
explicit space means that the compiler uses the type 24 version which is PA2.0
only resulting in an illegal instruction crash.

The test in pdc_console_tty_close '!tty->count' was always wrong
because tty->count is decremented after tty->ops->close is called and
thus can never be zero. Hence the 'then' branch was never executed and
the timer never deleted.

This did not matter until commit 5dd5bc40 ("TTY: pdc_cons, use
tty_port").  There we needed to set TTY in tty_port to NULL, but this
never happened due to the bug above.

So change the test to really trigger at the last close by changing the
condition to 'tty->count == 1'.

Well, the driver should not touch tty->count at all.  It should use
tty_port->count and count open count there itself.

Since we no longer need the VM_ALWAYSDUMP flag, let's use the freed bit
for 'VM_NODUMP' flag.  The idea is is to add a new madvise() flag:
MADV_DONTDUMP, which can be set by applications to specifically request
memory regions which should not dump core.

The specific application I have in mind is qemu: we can add a flag there
that wouldn't dump all of guest memory when qemu dumps core.  This flag
might also be useful for security sensitive apps that want to absolutely
make sure that parts of memory are not dumped.  To clear the flag use:
MADV_DODUMP.
