      Have os_validate pass the MAP_NORESERVE flag to mmap. This allows · 274a7d48
      dtc authored
      users with low swap plus memory to run without enabling the
      non-standard and perhaps undesirable overcommit_memory option. With
      this change the current scheme of splitting mmap operations into
      smaller pieces to bypass the kernel checks is no longer necessary,
      and this code has been cleaned up.

      Changes for Linux running on Alpha. · 25b808fb

      From: Julian Dolby <dolby@csag-226-8.UCSD.EDU>
      
        Enclosed below are diffs against the cvs repository as of Feb 12;
      aside from minor changes like using different include files
      (e.g. validate.h instead of x86-validate.h in Linux-os.c) and adding
      alpha-linux specifics unix-glibc2.lisp, there are two code changes.
      
       The first is to signal handling. I had to put the POSIX-SIGS
      ifdefs into places used by alpha but not by x86, and I ifdef'ed out
      most of the linux #define kludges for signals for alpha linux, since
      alpha linux uses OSF/1 signals rather than linux ones.
      
       The second is that the trick of or'ing 2 into the reg_ALLOC address
      to cause faults does not work on alpha linux since the kernel traps
      and handles the unaligned access; I did not find a way to change that
      kernel behavior, so I changed the code to or (1<<63) into the address
      to cause a seg fault, and then check, in the seg fault handler, to see
      if the high-order address bits are set.
      
       One change I made is to the memory layout (lisp/alpha-validate.h and
      compiler/alpha/parms.lisp); that change is not needed to make lisp run
      on alpha linux, but is there because I wanted more heap space.
