    [PATCH] x86-64 merge · f3081f5b
    Andi Kleen authored
    This patch depends on the i386 MTRR driver cleanup I sent earlier.
    
     - Support non executable mappings for x86-64. data/heap are non executable
       by default now.
     - Beginnings of software suspend from Pavel (not working yet)
     - Support generic compat functions and remove some shared code
       in the 32bit emulation (Stephen Rothwell)
     - Support hugetlbfs
     - Some makefile updates
     - Make sure all 32bit emulation functions return long, not int.
       This fixes some problems with ERESTARTNOSYS.et.al. leaking to userspace.
     - Add new system calls.
     - Fix long standing fs/gs context switch bugs (thanks to Karsten Keil
       for helping to fix that mess). Also make sure the gs selector is
       set to 0 after an exec.
     - Simplify TLS switching
     - Paranoid CPUID check at bootup
     - Reorder scatterlist to be more space efficient (Jes Soerensen)
     - Enlarge 32bit address space to full 4GB.
     - Beginnings of 32bit SYSCALL support (not completely working yet
       and vsyscall page miss yet)
     - Various merges from i386
     - New module loader
     - Support threaded core dump (XMM saving for 32bit programs doesn't
       work, but it appears to be broken on i386 too)
     - Fix bug in signal stack rounding
     - Remove DRM 32bit emulation.
     - Use MTRR driver from i386
     - Use bootflag.c from i386
     - Various other fixes and cleanups.
