Many RTC routines were not protected against each other, so there are
potential races, for example, ntp-update against /dev/rtc.  This patch
fixes them using rtc_lock.

The mips_rtc_lock is no longer needed because RTC operations should be
protected already by other mechanism. (rtc_lock, local_irq_save, etc.)
    
Also, locking whole rtc_get_time/rtc_set_time should be avoided while
some RTC routines might take very long time (a few seconds).

This patch removes page_pte_prot and page_pte macros from all
architectures.  Some architectures define both, some only page_pte (broken)
and others none.  These macros are not used anywhere.

page_pte_prot(page, prot) is identical to mk_pte(page, prot) and
page_pte(page) is identical to page_pte_prot(page, __pgprot(0)).

* The following architectures define both page_pte_prot and page_pte

  arm, arm26, ia64, sh64, sparc, sparc64

* The following architectures define only page_pte (broken)

  frv, i386, m32r, mips, sh, x86-64

* All other architectures define neither

to it in an asm() block, and we're running on a system with 64-bit
registers, it is vitally important that we sign extend it correctly before
returning to C.  Otherwise the stray high bits will be preserved into
csum_fold, and on the SB-1 processor, 32-bit arithmetic on a non
sign-extended register will yield surprising results.
