Consolidate these into the new cciss_defs.h file. This patch doesn't change
the definitions exposed under include/linux, so userspace apps shouldn't

CacheFiles: Fix a race in cachefiles_delete_object() vs rename
vfs: don't call ima_file_check() unconditionally in nfsd_open()
fs: inode - remove 8 bytes of padding on 64bits allowing 1 more objects/slab under slub
Switch proc/self to nd_set_link()
fix LOOKUP_FOLLOW on automount "symlinks"
- Add commit_metadata export_operation to allow the underlying filesystem to
decide how to commit an inode most efficiently.
- Usage of nfsd_sync_dir and write_inode_now has been replaced with the
commit_metadata function that takes a svc_fh.
- The commit_metadata function calls the commit_metadata export_op if it's
there, or else falls back to sync_inode instead of fsync and write_inode_now
because only metadata need be synced here.
- nfsd4_sync_rec_dir now uses vfs_fsync so that commit_metadata can be static

The most needed command from nl80211, which Wireless Extensions had,
is support for power save mode. Add a simple command to make it possible
to enable and disable power save via nl80211.
I was also planning about extending the interface, for example adding the
timeout value, but after thinking more about this I decided not to do it.
Basically there were three reasons:
Firstly, the parameters for power save are very much hardware dependent.
Trying to find a unified interface which would work with all hardware, and
still make sense to users, will be very difficult.
Secondly, IEEE 802.11 power save implementation in Linux is still in state
of flux. We have a long way to still to go and there is no way to predict
what kind of implementation we will have after few years. And because we
need to support nl80211 interface a long time, practically forever, adding
now parameters to nl80211 might create maintenance problems later on.
Third issue are the users. Power save parameters are mostly used for
debugging, so debugfs is better, more flexible, interface for this.
For example, wpa_supplicant currently doesn't configure anything related
to power save mode. It's better to strive that kernel can automatically
optimise the power save parameters, like with help of pm qos network
and other traffic parameters.
Later on, when we have better understanding of power save, we can extend
this command with more features, if there's a need for that.

Another PCMCIA device with Intersil Prism chipset has been reported:
Socket 0:
product info: "Gigabyte", "GN-WLM01_P25L_ADAPTER", "ISL37300P", "Eval-RevA"
manfid: 0x02e0, 0x1011
function: 6 (network)
As it's the case with some other Prism based devices, the third ID
string contains a design name that should be sufficient to identify the
card as having Intersil Prism chipset and thus compatible with both
orinoco_cs and hostap_cs.
Introduce PCMCIA_DEVICE_PROD_ID3 that matches the third ID string only.
Use it in orinoco_cs and hostap_cs to match cards with the third ID
string indicating Prism chipset. Remove corresponding entries that use
PCMCIA_DEVICE_PROD_ID123.
