e376fdf420 MIPS: Malta: Don't crash on spurious interrupt.
48d480b0bd [[MIPS] Malta: Fix off by one bug in interrupt

the set of pending interrupts happens to be empty.

This is trivial to trigger with a RM5261 CPU module running a 64-bit kernel and results
in something like the following:

636221b86c MIPS: Malta: Remove RTC Data Mode bootstrap breakage
YAMON requires and enforces the RTC Data Mode (Register B, DM bit) to
binary, that is the bit is set every time the board goes through the
firmware bootstrap sequence.  Likewise its calendar manipulation commands
interpret or set the RTC registers unconditionally as binary, never
actually checking what the value of the DM bit is, under the (correct)
assumption that it has been previously set, to indicate the binary mode.

 A change to Linux a while ago however introduced a platform-specific
tweak that clears that bit and therefore forces the data mode to BCD.
This causes clock corruption and misinterpretation that has to be fixed up
by user-mode tools in system startup scripts as the initial clock is often
incorrect according to the BCD interpretation forced.

 This change removes the hack; a comment included refers to alarm code,
but even if it was broken at one point by requiring the BCD mode, it
should have been trivially corrected and even if not, given how rarely the
alarm feature is used, that was not really a reasonable justification to
break the system clock that is indeed used by virtually everything.  And
either way the alarm code has been since fixed anyway.

c9e854cf94 GPIO: MIPS: lantiq: fix overflow inside stp-xway driver
The driver was using a 16 bit field for storing the shadow value of the shift
register cascade. This resulted in only the first 2 shift registeres receiving
the correct data. The third shift register would always receive 0x00.

Fix this by using a 32bit field for the shadow value.

Implement support for pinctrl on lantiq/xway socs. The IO core found on these

located in the arch/ folder.

89a897fbd8 Pull request from git://github.com/prasad-joshi/logfs_upstream.git
There are few important bug fixes for LogFS
 
 9f0bbd8 logfs: query block device for number of pages to send with bio
 	This BUG was found when LogFS was used on KVM. The patch fixes
 	the problem by asking for underlaying block device the number
 	of pages to send with each BIO.
 
 41b93bc logfs: maintain the ordering of meta-inode destruction
 	LogFS maintains file system meta-data in special inodes. These
 	inodes are releated to each other, therefore they must be
 	destroyed in a proper order.
 
 ddb24bb logfs: create a pagecache page if it is not present
 
 cd8bfa9 logfs: initialize the number of iovecs in bio
 	LogFS used to panic when it was created on an encrypted LVM
 	volume. The patch fixes the problem by properly initializing
 	the BIO.
 
 d2dcd90 logfs: destroy the reserved inodes while unmounting
