mtd: bcm47xxpart: alternative MAGIC for board_data partition
Some devices (like WNDR3700v3) have board_data without MPFR magic, some
extra header or extra NVRAM around 0x100. In such case we have to look
for another magic which is BD 0B 0D BD (BD probably stands for Board
Data). It's located "far far away", so instead of extending buffer add
another mtd_read.

mtd: Hide CONFIG_MTD_BLKDEVS from the menu
Make this option a hidden one and get a cleaner configuration.
This option just selects a common infrastructure for MTD-based devices
to expose a block interface. There is no point in allowing a separate

NFS: dprintk() should not print negative fileids and inode numbers
A fileid in NFS is a uint64. There are some occurrences where dprintk()
outputs a signed fileid. This leads to confusion and more difficult to
read debugging (negative fileids matching positive inode numbers).

nfs: fix dead code of ipv6_addr_scope
The correct way to check on IPV6_ADDR_SCOPE_LINKLOCAL is to check with
the ipv6_addr_src_scope function.
Currently this can't be work, because ipv6_addr_scope returns a int with
a mask of IPV6_ADDR_SCOPE_MASK (0x00f0U) and IPV6_ADDR_SCOPE_LINKLOCAL
is 0x02. So the condition is always false.

When a task enters call_refreshresult with status 0 from call_refresh and
!rpcauth_uptodatecred(task) it enters call_refresh again with no rate-limiting
or max number of retries.
Instead of trying forever, make use of the retry path that other errors use.
This only seems to be possible when the crrefresh callback is gss_refresh_null,
which only happens when destroying the context.
To reproduce:
1) mount with sec=krb5 (or sec=sys with krb5 negotiated for non FSID specific
operations).
2) reboot - the client will be stuck and will need to be hard rebooted

ACPI: introduce helper interfaces for _DSM method
There are several drivers making use of ACPI _DSM method to detect
and invoke device specific methods. Currently every driver has
implemented its private version to support ACPI _DSM method.
So this patch introduces three helper functions to support ACPI _DSM

It helps to simplify code and improve code readability.
