[ARM] Add flush_cache_user_page() for sys_cacheflush()
Add flush_cache_user_page() to handle sys_cacheflush. Userspace
wants to use this call to ensure I/D cache coherency for runtime-
built code (eg, used by Java etc). This does not fit well with
the purpose of flush_cache_range(), so provide
flush_cache_user_range() instead.

[ARM] Fix copy/clear user page functions for VIPT aliasing caches.
This fixes the copy and clear user page functions for ARMv6 aliasing
caches. When we copy data into a page destined for user space, we
must make sure that there are no dirty cache lines associated with
the kernel space mapping of this page.

[ARM PATCH] 2033/1: IOP3xx patch submission (1/6)
Patch from Dave Jiang
This patch depends on the applied patches of 1963/1 2017/1
This is the arch/arm/boot directory
As to address RMK's previous questions in head-xscale.S, all that are workarounds
for improper things coming from redboot. Currently the distribution redboot for IOP does not pass in correct MACH ID or setup the memory map correctly after exec (according to Deepak). So we have to fix it. I'm working on pushing the IOP redboot developer to fix those things at a later date.

This makes /proc/cpuinfo more accurate on many ARM processors, so that
for example ARMv5TEJ processors always show they have Thumb (T),
EDSP (E), and Java (J) capability.
* prism54_get_freq is incorrectly returning channel
* and not frequency. Wireless tools detect this, but
* other programs do not, leading to insane reported

[PATCH] out-of-line locks / generic
This patch achieves out of line spinlocks by creating kernel/spinlock.c
and using the _raw_* inline locking functions.
Now, as much as this is supposed to be arch agnostic, there was still a
fair amount of rummaging about in archs, mostly for the cases where the
arch already has out of line locks and i wanted to avoid the extra call,
saving that extra call also makes lock profiling easier. PPC32/64 was
an example of such an arch and i have added the necessary profile_pc()
function as an example.
Size differences are with CONFIG_PREEMPT enabled since we wanted to
determine how much could be saved by moving that lot out of line too.
attached is a patch that polls the media setting for non GigE nForce
nics:
Without polling, media changes are not autodetected. This is fatal,
because the nic initialization is asynchroneous, thus "modprobe;ifup"
resulted in a dead network connection. The attached patch fixes that
problem.
It's a repost of a patch I sent around three weeks ago: you objected
that I rely on the nic irq instead of a software timer. I've documented
why this is ok.

[PATCH] fix sched_domains hotplug bootstrap ordering vs. cpu_online_map issue
cpu_online_map is not set up at the time of sched domain initialization
when hotplug cpu paths are used for SMP booting.
At this phase of bootstrapping, cpu_possible_map can be used by the
various architectures using cpu hotplugging for SMP bootstrap, but the
manipulations of cpu_online_map done on behalf of NUMA architectures,
done indirectly via node_to_cpumask(), can't, because cpu_online_map
starts depopulated and hasn't yet been populated.
On true NUMA architectures this is a distinct cpumask_t from
cpu_online_map and so the unpatched code works on NUMA; on non-NUMA
architectures the definition of node_to_cpumask() this way breaks and
would require an invasive sweeping of users of node_to_cpumask() to
change it to e.g. cpu_possible_map, as cpu_possible_map is not suitable
for use at runtime as a substitute for cpu_online_map.

Many entries in the CREDITS file are not properly sorted in alphabetical
order, despite the note in the file that it is supposed to be sorted like
that.
This patch attempts to sort the CREDITS file properly. No existing entries
were changed, merely moved around in the file. There where a few tricky
names that I was unsure how to sort (names with characters such as ü, ö,
and people with many names where it was unclear to me what name to sort by
etc), in those cases I've usually left the names where they were unless it
was glaringly obvious they were in the wrong spot.
I've also taken the liberty to add my own name to the file - I have
contributed several tiny/small fixes/cleanups etc over the years.
