As long as there is no other non-const variable marked __initdata in the
same compilation unit it doesn't hurt. If there were one however
compilation would fail with

	error: $variablename causes a section type conflict

because a section containing const variables is marked read only and so
cannot contain non-const variables.

Pull Sparc updates from David S. Miller:

 1) Remove the idiotic situation wherein Leon was a special case in all
    of the TLB/cache handling code.

    The worst side effect of this bogosity is that you couldn't build a
    kernel with Leon support enabled (to get better build coverage), and
    test boot it on a non-LEON cpu.

    Leon is, in all core respects, programatically identical to the
    32-bit SRMMU.  Except that they put the TLB registers in a different
    alternate address space location.

    Through code patching (for fast paths) and run time checks, this
    issue is now a thing of the past.

    From Sam Ravnborg.

 2) There was a mis-merge of arch/sparc/Kconfig for one of the
    clockevents changes that went in, causing 32-bit sparc to start
    failing to build.

    I merged in your tree to get those clockevents changes (and added a
    note to the merge commit) then added Stephen Rothwell's fix for the
    merge error.

 3) Software quad floating point emulation was not working properly on
    more recent Niagara chips, because the way the situation is reported
    by the cpu has changed.

    Nobody noticed because gcc emits calls to software emulation
    routines in glibc.

Current failure paths attempt to free resources which we failed to request
and disable resources which we failed to enable ones. This leads to kernel
oops/panic. This patch does some simple re-ordering to prevent this from
happening.

disable_cb is just an optimization: it

In particular it doesn't have any effect when

This was reported by Dave Jones, but was reproducible with the
libhugetlbfs test cases, so shame on me for not running them in the
first place.

With this, the oops is gone, and the output of libhugetlbfs's
run_tests.py is identical to plain 3.4 again.

[ Marked for stable, since this was introduced by commit c50ac050
  ("hugetlb: fix resv_map leak in error path") which was also marked for
  stable ]

Function pat_pagerange_is_ram() scales poorly to large address
ranges, because it probes the resource tree for each page.

On a 2.6 GHz Opteron, this function consumes 34 ms for a 1 GB range.

It is called twice during untrack_pfn_vma(), slowing process
cleanup and handicapping the OOM killer.

This replacement consumes less than 1ms, under the same conditions.

Since there are uses for I2C_M_NOSTART which are much more sensible and
standard than most of the protocol mangling functionality (the main one
being gather writes to devices where something like a register address
needs to be inserted before a block of data) create a new I2C_FUNC_NOSTART
for this feature and update all the users to use it.

Also strengthen the disrecommendation of the protocol mangling while we're
at it.

In the case of regmap-i2c we remove the requirement for mangling as
I2C_M_NOSTART is the only mangling feature which is being used.

As the bus driver side implementation of I2C_M_RECV_LEN is heavily
tied to SMBus, we can't support received length over 32 bytes, but
let's at least support that.

In practice, the caller will have to setup a buffer large enough to
cover the case where received length byte has value 32, so minimum
32 + 1 = 33 bytes, possibly more if there is a fixed number of bytes
added for the specific slave (for example a checksum.)
