[PATCH] 4GB split: fix compilation w/o HIGHMEM support

actually it's a hack. 4GB split obviously won't work
w/o HIGHMEM support, due to errors in pgd_ctor()/pmd_ctor().

Patch from Evgeny Kravtsunov <emkravts@openvz.org><br/>
[PATCH] CPT: TUN/TAP support in checkpointing

Now live migration of VE with openvpn inside is supported.

1) tun/tap driver updated:<br/>
- Field void *bind_file added to tun_struct. Field is used for storing pointer
to open /dev/net/tun file. This pointer is to be written to dumpfile: on
restore it is necessary to carry out binding of created tun_struct to open
file /dev/net/tun.

2) dump:<br/>
- Introduced struct cpt_tuntap_image for storing tun/tap device related data.
Corresponding object type CPT_OBJ_NET_TUNTAP added.

- Flag value CPT_DENTRY_TUNTAP introduced. It is necessary for setting
corresponding bit in cpt_lflags field of cpt_file_image for /dev/net/tun
file.

- Call of function cpt_dump_ifinfo is placed after cpt_dump_files_struct and
cpt_dump_fs_struct. This is necessary for finding /dev/net/tun file pos in
file image and storing pos value during dump of tun/tap device.

- Function cpt_dump_tuntap introduced, cpt_dump_link is updated by call of
cpt_dump_tuntap. The CPT_SECT_NET_DEVICE section, that is common for all net
devices is used for tun/tap device: tun->dev netdevice data is stored in
cpt_netdev_image image type and tun_struct data is stored inside
cpt_tuntap_image. Both cpt_netdev_image and cpt_tuntap_image images are
stored inside CPT_SECT_NET_DEVICE section.

- Set of checks updated that allow dumping netdevices (in
check_unsupported_netdevices and cpt_dump_link) and open files
(dump_one_file, dump_content_chrdev).

3) restore:<br/>
- Function rst_restore_tuntap introduced. Call of rst_restore_tuntap is placed
to rst_restore_netdev. rst_restore_tuntap creates tun/tap netdevice and
tun_struct on destination HN, initializes them by values taken from
cpt_netdev_image and cpt_tuntap_image objects, restores /dev/net/tun file
from corresponding position of cpt_file_image and binds opened file to newly
created tun_struct.

- Function open_special updated by adding check for tun/tap related file. This
makes possible to restore /dev/net/tun char device by calling rst_file.

[NETFILTER]: ip_tables: fix compat related crash

check_compat_entry_size_and_hooks iterates over the matches and calls
compat_check_calc_match, which loads the match and calculates the
compat offsets, but unlike the non-compat version, doesn't call
->checkentry yet. On error however it calls cleanup_matches, which in
turn calls ->destroy, which can result in crashes if the destroy
function (validly) expects to only get called after the checkentry
function.

Add a compat_release_match function that only drops the module reference
on error and rename compat_check_calc_match to compat_find_calc_match to
reflect the fact that it doesn't call the checkentry function.

[PATCH] netfilter: add xt_MARK 32bit compat

xt_MARK doesn't have the compat function while its entry
structure (xt_mark_target_info_v1) requires it.

Note 1:
<source lang="c">
/* Version 0 */
struct xt_mark_target_info {
unsigned long mark;
};
</source>
So the struct size differs for 32bit/64bit nodes, but mainstream does not
have a compat for it. ipv6 variant uses xt_mark_target_info (v0) so
the testing will show if the compat is really required.

<div class="change">
Patch from Evgeny Kravtsunov <emkravts@openvz.org><br/>
[PATCH] VE: virtualize ipt_recent

Patch virtualizes ipt_recent module in the following way:

1) Introduced struct ve_ipt_recent and corresponding _ipt_recent entry in
ve_struct. ve_ipt_recent contains global variables from ipt_recent module.

2) Functions init_ipt_recent, fini_ipt_recent implemented.
Current functions designed to be called from ipt_recent_init/fini and
ipt_recent_checkentry/destroy in purpose to alloc ve_ipt_recent
structure and initialize/cleanup _ipt_recent entry in ve_struct .

3) Functions ipt_recent_init, ipt_recent_exit updated.

Note: ipt_recent match does not need compat function as it is needed for
hashlimit for example. It is so because sizeof(struct ipt_recent_info) does
not depend on the architecture:
<source lang="c">
struct ipt_recent_info {
u_int32_t seconds;
u_int32_t hit_count;
u_int8_t check_set;
u_int8_t invert;
char name[IPT_RECENT_NAME_LEN];
u_int8_t side;
};
</source>
Testing was carried out for both 64- and 32-bit ve on 64-bit HN.

[PATCH] VE: mark venet as vlan-incapable

Many places in vlan code assume ethernet underlying device,
which is not working for venet.
So mark vene as vlan-incapable.

Given that vlan over veth works and vlan over venet reliably
oopses kernel, mark venet as vlan-incapable, so that registration code
