ARM: introduce atag_offset to replace boot_params
The boot_params member of the mdesc structure is used to provide a
default physical address for the ATAG list. Since this value is fixed
at compile time and sometimes based on constants such as ARCH_PHYS_OFFSET,
it gets in the way of runtime PHYS_OFFSET and CONFIG_ARM_PATCH_PHYS_VIRT
usage.
Let's introduce atag_offset which should contains only the relative
offset from PHYS_OFFSET instead of an absolute value, in preparation
to move all instance of boot_params over to it.

mm: fix wrong vmap address calculations with odd NR_CPUS values
Commit
db64fe02258f ("mm: rewrite vmap layer") introduced code that does
address calculations under the assumption that VMAP_BLOCK_SIZE is a
power of two. However, this might not be true if CONFIG_NR_CPUS is not
set to a power of two.
Wrong vmap_block index/offset values could lead to memory corruption.
However, this has never been observed in practice (or never been
diagnosed correctly); what caught this was the BUG_ON in vb_alloc() that
checks for inconsistent vmap_block indices.
To fix this, ensure that VMAP_BLOCK_SIZE always is a power of two.

move RLIMIT_NPROC check from set_user() to do_execve_common()
The patch http://lkml.org/lkml/2003/7/13/226 introduced an RLIMIT_NPROC
check in set_user() to check for NPROC exceeding via setuid() and
similar functions.
Before the check there was a possibility to greatly exceed the allowed
number of processes by an unprivileged user if the program relied on
rlimit only. But the check created new security threat: many poorly
written programs simply don't check setuid() return code and believe it
cannot fail if executed with root privileges. So, the check is removed
in this patch because of too often privilege escalations related to
buggy programs.
The NPROC can still be enforced in the common code flow of daemons
spawning user processes. Most of daemons do fork()+setuid()+execve().
The check introduced in execve() (1) enforces the same limit as in
setuid() and (2) doesn't create similar security issues.
Neil Brown suggested to track what specific process has exceeded the
limit by setting PF_NPROC_EXCEEDED process flag. With the change only
this process would fail on execve(), and other processes' execve()
behaviour is not changed.
Solar Designer suggested to re-check whether NPROC limit is still
exceeded at the moment of execve(). If the process was sleeping for
days between set*uid() and execve(), and the NPROC counter step down
under the limit, the defered execve() failure because NPROC limit was
exceeded days ago would be unexpected. If the limit is not exceeded
anymore, we clear the flag on successful calls to execve() and fork().
The flag is also cleared on successful calls to set_user() as the limit
was exceeded for the previous user, not the current one.
Similar check was introduced in -ow patches (without the process flag).
v3 - clear PF_NPROC_EXCEEDED on successful calls to set_user().

hwmon: (pmbus/lm25066) Ignore byte writes to non-zero pages
pmbus_clear_faults() attempts to clear faults on non-existing real pages.
As a result, the command error bit in the status register is set, and faults
are not really cleared.
All byte writes to non-zero pages are requests to clear the status register
on that page. Since non-zero pages are virtual and do not exist on the chip,
there is nothing to do, and such requests have to be ignored. This fixes
above problem.

ipv4: some rt_iif -> rt_route_iif conversions
As rt_iif represents input device even for packets
coming from loopback with output route, it is not an unique
key specific to input routes. Now rt_route_iif has such role,
it was fl.iif in 2.6.38, so better to change the checks at
some places to save CPU cycles and to restore 2.6.38 semantics.
compare_keys:
- input routes: only rt_route_iif matters, rt_iif is same
- output routes: only rt_oif matters, rt_iif is not
used for matching in __ip_route_output_key
- now we are back to 2.6.38 state
ip_route_input_common:
- matching rt_route_iif implies input route
- compared to 2.6.38 we eliminated one rth->fl.oif check
because it was not needed even for 2.6.38
compare_hash_inputs:
Only the change here is not an optimization, it has
effect only for output routes. I assume I'm restoring
the original intention to ignore oif, it was using fl.iif
- now we are back to 2.6.38 state
