      [POWERPC] Move ELF_ET_DYN_BASE up to 512MB point · 7e60d1b4
      Anton Blanchard authored 
      I often test new versions of glibc by doing:

LD_LIBRARY_PATH=/XXX/lib /XXX/lib/ld.so.1 <binary>

One test case ended up SEGV'ing. Upon closer inspection ld.so was loaded
at 0x8000000 (128MB) with the heap right after it. Since we normally
link binaries at 0x10000000 (256MB) we only had about 128MB of space for
the heap:

00100000-00103000 r-xp 00100000 00:00 0           [vdso]
08000000-0801e000 r-xp 00000000 00:01 33079       /lib/ld-2.5.so
0802d000-0802f000 rwxp 0001d000 00:01 33079       /lib/ld-2.5.so
0802f000-08050000 rwxp 0802f000 00:00 0           [heap]
0fe91000-0ffd9000 r-xp 00000000 00:01 33082       /lib/libc-2.5.so
0ffd9000-0ffe8000 ---p 00148000 00:01 33082       /lib/libc-2.5.so
0ffe8000-0ffea000 r--p 00147000 00:01 33082       /lib/libc-2.5.so
0ffea000-0ffed000 rwxp 00149000 00:01 33082       /lib/libc-2.5.so
10000000-10004000 r-xp 00000000 00:01 76          /bin/sleep
10013000-10014000 rwxp 00003000 00:01 76          /bin/sleep
ffb41000-ffb56000 rw-p ffb41000 00:00 0           [stack]

One way to fix this is move ELF_ET_DYN_BASE from 0x08000000 to 0x20000000.
This allows 128MB for the binary (hopefully enough for even the most
crazy c++ apps), and with our current layout we will grow the heap up
and the stack down, allowing potentially gigabytes of heap:

      [PATCH] x86: fix PDA variables to work during boot · 9ee79a3d
      James Bottomley authored 
      The current PDA code, which went in in post 2.6.19 has a flaw in that it
doesn't correctly cycle the GDT and %GS segment through the boot PDA,
the CPU PDA and finally the per-cpu PDA.

The bug generally doesn't show up if the boot CPU id is zero, but
everything falls apart for a non zero boot CPU id.  The basically kills
voyager which is perfectly capable of doing non zero CPU id boots, so
voyager currently won't boot without this.

The fix is to be careful and actually do the GDT setups correctly.

      [PATCH] vmx: Fix register constraint in launch code · e0015489
      Herbert Xu authored 
      Both "=r" and "=g" breaks my build on i386:

  $ make
    CC [M]  drivers/kvm/vmx.o
  {standard input}: Assembler messages:
  {standard input}:3318: Error: bad register name `%sil'
  make[1]: *** [drivers/kvm/vmx.o] Error 1
  make: *** [_module_drivers/kvm] Error 2

The reason is that setbe requires an 8-bit register but "=r" does not
constrain the target register to be one that has an 8-bit version on
i386.

According to

	http://gcc.gnu.org/bugzilla/show_bug.cgi?id=10153

the correct constraint is "=q".
