Bug Description

Hi

user-mode-linux builds on amd64 but fails to build on i386 with:
[...]
  CC fs/binfmt_script.o
  CC fs/binfmt_elf.o
fs/binfmt_elf.c: In function 'load_elf_binary':
fs/binfmt_elf.c:723: error: 'nx_enabled' undeclared (first use in this function)
fs/binfmt_elf.c:723: error: (Each undeclared identifier is reported only once
fs/binfmt_elf.c:723: error: for each function it appears in.)
fs/binfmt_elf.c:724: error: implicit declaration of function 'arch_add_exec_range'
make[2]: *** [fs/binfmt_elf.o] Error 1
make[1]: *** [fs] Error 2
[...]

see http://launchpadlibrarian.net/39441781/buildlog_ubuntu-lucid-i386.user-mode-linux_2.6.32-1um-3ubuntu1_FAILEDTOBUILD.txt.gz

This is due to an Ubuntu patch (copied from RedHat) to add NX support in fs/binfmt_elf.c

Bye

  * New patch, 62_ubuntu-i386-um-no-nx-enabled, disable nx_enabled test in
    binfmt_elf when building UML as it's not available under ARCH=um; should
    fix i386 build; LP: #524849.
