[Devel] [VZ10 00/21] Fix !CONFIG_VE build

[Vladimir Riabchun]

There is a lot of CONFIG_VE logic, that is not covered by CONFIG_VE.
This is and attempt to make the kernel compile with minimal
useless code changes - thus it is not expected to boot now.

Some ve_struct fields were made unconditional, because the other
option is changing all the code that touches this field.

ve0 is absent and all ve objects are NULLs with !CONFIG_VE.
This is intentional - while it makes kernel less bootable (it will
probably never be), this is a movement away from having ve0 and
all the CONFIG_VE logic when this config is disabled.

Vladimir Riabchun (21):
  ve/net: Have net->owner_ve when !CONFIG_VE
  ve/vma: Fix NULL dereference when accessing ve->vdso_image_*
  ve: Fix obvious null dereferences when !CONFIG_VE
  ve: Fix ve.h when !CONFIG_VE
  x86/cpuid_fault: Make it compile with !CONFIG_VE
  ve/sched.h: Fix errors and warnings when !CONFIG_VE
  ve/module: Fix "no return statement" error
  ve: Fix usages of ve0
  ve/cgroup: Fix errors when !CONFIG_VE
  ve/vzstat.h: Move KSTAT_ALLOC_MAX_LAT_PERIOD outside CONFIG_VE
  ve/aio: Hide aio pid_entry under CONFIG_VE
  ve/kernfs: Fix when !CONFIG_VE
  ve: Fix compiler warning about CONFIG_VE usage
  ve/kthread: Remove ifdef CONFIG_VE
  ve/fs: Define ve_fsync_behavior only when CONFIG_VE
  ve/tty: Use vtty_alloc_tty_struct only when CONFIG_VE
  ve/connector: Hide cn_ss_hook under CONFIG_VE
  ve/fsopen: fscontext_finalize_lazy_opts has no return statement when
    !CONFIG_VE
  ve/binfmt_elf: Include ve.h only when CONFIG_VE
  vmalloc: Rename module parameter variable
  ve/sunrpc: Use kthread_create_on_node when !CONFIG_VE
