Revert "Revert "staging/lustre: drop CONFIG_BROKEN dependency""

This reverts commit 37d4093fd34775bbbf99bddb84a711bdb3ec6d5c.

I've verified that we now don't break build on X86_64 allmodconfig.

staging/lustre/libcfs: cleanup linux-crypto

We don't need to implement crc32 and crc32pclmul on our own.
The crc32-pclmul support was merged into the 3.8 kernel in commit
78c37d1, no need to keep a local copy in Lustre anymore.
The crc32 implementation is identical to crypto-crc32. So drop
Lustre's private implementation and select kernel crypto in Kconfig.

staging: rtl8192u: replace macro rx_hal_is_cck_rate() in r8192U_core.c

This patch replaces macro rx_hal_is_cck_rate() with
the static inline function rx_hal_is_cck_rate().

This replacement was suggested by Dan Carpenter and
has the following benefits:
- improves code readability
- guarantees type safety
- improves code efficiency by enforcing the evaluation of
  the simple boolean expression (!pdrvinfo->RxHT) to be
  done before the evaluation of the more complex one
  (pdrvinfo->RxRate == DESC90_RATE1M ||
   pdrvinfo->RxRate == DESC90_RATE2M ||
   pdrvinfo->RxRate == DESC90_RATE5_5M ||
   pdrvinfo->RxRate == DESC90_RATE11M)

Check to see if allocation by kzalloc() or usb_alloc_urb() was unsuccessful

This avoids unnecessary use of usb_alloc_urb() & usb_free_urb() if kzalloc()

Also, makes the code better structured & easier to understand.

The timeout detection implemented in this driver isn't very

the polling thread often reported timeouts because the 50ms

To make atime update properly between 1.8 client and 2.x server,

- if MDS_ATTR_xTIME is set without MDS_ATTR_xTIME_SET and the client
  does not have OBD_CONNECT_FULL20, convert it to LA_xTIME in
  mdt_setattr_unpack().
- set both MDS_ATTR_xTIME | MDS_ATTR_xTIME_SET for timestamps in
  ll_prepare_close(). This allows us to fix the server-side timestamp
  setting in the future.
- remove attr_unpack() and convert the flags from MDS_ATTR_ to LA_*
  directly in mdt_attr_valid_xlate() instead.
- improve sanityn.sh test_23().

staging/lustre/changelog: fix CL_LAYOUT, accept all types

In order to avoid compatibility issues with older ChangeLog consumers,
change the new CL_LAYOUT record to use the value previously assigned
to CL_IOCTL.  The CL_IOCTL type was never used anywhere, and it didn't
really make any sense as a ChangeLog record, since it could really
mean anything at all.

The changelog_show_cb() function is renamed to changelog_kkuc_cb(),
since it is really about consuming the ChangeLog and passing it up to
the kernel-user-coms interface.  At some point we should consider to
implement a DBUS-based ChangeLog interface as well.

The changelog_kkuc_cb() "sanity check" on cr_type was removed, since
there is no reason the client kernel needs to know every record type
that is being passed to userspace.  It is up to the client tool to
determine what records that it can process.

staging/lustre: Revert "LU-2139 osc: Track and limit "unstable" pages"

This seems to be causing multiple issues: LU-3274, LU-3277

[The original commit is folded in the large Lusre patch. So we don't
have an exact commit to revert for kernel client -- Peng Tao]

staging/lustre/debug: quiet noisy console error messages

Quiet a number of overly noisy and unhelpful console error
messages. Improve the format of other nearby errors.

In the case of {lod,lov}_fix_desc_stripe_size(), this doesn't
even need a console message unless it is actually changing
some stripe size that is below the minimum. Typically it is
only zero and is being bumped up to the default value.

staging/lustre/ofd: refill env in ofd_get_info

Because ofd_get_info(KEY_FIEMAP) might be called from

so it refill refill in ofd_get_info.
