      power: supply: qcom_battmgr: remove bogus do_div() · 92304df8
      Arnd Bergmann authored
      The argument to do_div() is a 32-bit integer, and it was read from a
      32-bit register so there is no point in doing a 64-bit division on it.
      
      On 32-bit arm, do_div() causes a compile-time warning here:
      
          include/asm-generic/div64.h:238:22: error: passing argument 1 of '__div64_32' from incompatible pointer type [-Werror=incompatible-pointer-types]

      capability: just use a 'u64' instead of a 'u32[2]' array · f122a08b
      Linus Torvalds authored
      Back in 2008 we extended the capability bits from 32 to 64, and we did
      it by extending the single 32-bit capability word from one word to an
      array of two words.  It was then obfuscated by hiding the "2" behind two
      macro expansions, with the reasoning being that maybe it gets extended
      further some day.
      
      That reasoning may have been valid at the time, but the last thing we
      want to do is to extend the capability set any more.  And the array of
      values not only causes source code oddities (with loops to deal with
      it), but also results in worse code generation.  It's a lose-lose
      situation.
      
      So just change the 'u32[2]' into a 'u64' and be done with it.
      
      We still have to deal with the fact that the user space interface is
      designed around an array of these 32-bit values, but that was the case
      before too, since the array layouts were different (ie user space
      doesn't use an array of 32-bit values for individual capability masks,
      but an array of 32-bit slices of multiple masks).
      
      So that marshalling of data is actually simplified too, even if it does
      remain somewhat obscure and odd.
      
      This was all triggered by my reaction to the new "cap_isidentical()"
      introduced recently.  By just using a saner data structure, it went from
      
      	unsigned __capi;
      	CAP_FOR_EACH_U32(__capi) {
      		if (a.cap[__capi] != b.cap[__capi])
      			return false;
      	}
      	return true;
      
      to just being
      
      	return a.val == b.val;
      
      instead.  Which is rather more obvious both to humans and to compilers.

      Pull moar xfs updates from Darrick Wong:
       "This contains a fix for a deadlock in the allocator. It continues the
        slow march towards being able to offline AGs, and it refactors the
        interface to the xfs allocator to be less indirection happy.
      
        Summary:
      
         - Fix a deadlock in the free space allocator due to the AG-walking
           algorithm forgetting to follow AG-order locking rules
      
         - Make the inode allocator prefer existing free inodes instead of
           failing to allocate new inode chunks when free space is low
      
         - Set minleft correctly when setting allocator parameters for bmap
           changes
      
         - Fix uninitialized variable access in the getfsmap code
      
         - Make a distinction between active and passive per-AG structure
           references. For now, active references are taken to perform some
           work in an AG on behalf of a high level operation; passive
           references are used by lower level code to finish operations
           started by other threads. Eventually this will become part of
           online shrink
      
         - Split out all the different allocator strategies into separate
           functions to move us away from design antipattern of filling out a
           huge structure for various differentish things and issuing a single
           function multiplexing call
      
         - Various cleanups in the filestreams allocator code, which we might
           very well want to deprecate instead of continuing
      
         - Fix a bug with the agi rotor code that was introduced earlier in
           this series"
