The behavior of these system calls is slightly different between architectures, as determined by CONFIG_ARCH_WANT_IPC_PARSE_VERSION symbol. sw64 expect the caller to pass the IPC_64 flag. So switch to old-style semctl and shmctl to maintain libc compatibility.

It never support a.out and ECOFF binaries on sw64 systems, and the related headers can be removed.
The user.h is only used for a.out files, and we use generic version instead.

It used to clear VM_IO and VM_PFNMAP of the vma flag, then set again before release this vma to get the physical pages corresponding to the user virtual address.
But __get_user_pages() will fail because of bad pte without VM_PFNMAP if HAVE_GENERIC_GUP and ARCH_HAS_PTE_SPECIAL are enabled.
To fix this issue, remap pages by vm_insert_page() to insert individual pages allocated for guest.
