Commit e545a6140b698b2494daf0b32107bdcc5e901390 ("kernel/cpu.c: create
a CPU_STARTING cpu_chain notifier") added a notify_cpu_starting()
notifier event, and hit every arch except sparc64.
Fix that missed case.

older versions of gcc do not recognize that ieee80211_rx_h_mesh_fwding()
is unused when CONFIG_MAC80211_MESH is disabled:
net/built-in.o: In function `ieee80211_rx_h_mesh_fwding':
rx.c:(.text+0xd89af): undefined reference to `mpp_path_lookup'
rx.c:(.text+0xd89c6): undefined reference to `mpp_path_add'
as this code construct:
if (ieee80211_vif_is_mesh(&sdata->vif))
CALL_RXH(ieee80211_rx_h_mesh_fwding);
still causes ieee80211_rx_h_mesh_fwding() to be linked in.
Protect these places with an #ifdef.

The comment in the code was asking "Do we have to do this?", and according
to x86 and s390 the answer is no, the scheduler will do it before calling

A single full sync (mb()) is requrired to order the mmio to the qirr reg
with the set or clear of the message word. However, test_and_clear_bit
has the effect of smp_mb() and we are not doing any other io from here,
so we don't need a mb per bit processed.

EOI normally has the side effect of returning the cpu to the base
priority to recieve the next interrupt. This is actually controlled
by the top byte of the xirr register. When we are exiting the
kernel in kexec we must eoi the ipi for the next kernel because we
never return from the handler, but we want to leave interrupt
delivery blocked until the next kernel takes action.
Since the hardware ipi vector is fixed, its easiest to just do the
eoi explicitly.

This factors out processors joining and unjoining the Global Interrupt
Queue into a separate function.
There is a bit of math to calculate the arguments to rtas to join
or leave the global interrupt queue, and a warning on failure
afterwards. Make a helper for the 3 callers.

xics supports only one ipi per cpu, and expects software to use some
queue to know why the interrupt was sent. In Linux, we use a an array
of bitmaps indexed by cpu to identify the message. Currently the bits
are set in smp.c and decoded in xics.c, with the data structure in a
header file. Consolidate the code in xics.c similar to mpic and other
interrupt controllers.
Also, while making the the array static, the message word doesn't need
to be volatile as set_bit and test_clear_bit take care of it for us, and
put it under ifdef smp.

Currently, the 'chunk_size' of an array must be at-least PAGE_SIZE.
This makes moving an array to a machine with a larger PAGE_SIZE, or
changing the kernel to use a larger PAGE_SIZE, can stop an array from
working.
For RAID10 and RAID4/5/6, this is non-trivial to fix as the resync
process works on whole pages at a time, and assumes them to be wholly
within a stripe. For other raid personalities, this restriction is
not needed at all and can be dropped.
So remove the test on chunk_size from common can, and add it in just
the places where it is needed: raid10 and raid4/5/6.

This patch renames hash_spacing and preshift to spacing and
sector_shift respectively with the following change of semantics:
Case 1: (sizeof(sector_t) <= sizeof(u32)).
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In this case, we have sector_shift = preshift = 0 and spacing =
2 * hash_spacing.
Hence, the index for the hash table which is computed by the new code
in which_dev() as sector / spacing equals the old value which was
(sector/2) / hash_spacing.
Note also that the value of nb_zone stays the same because both sz
and base double.
Case 2: (sizeof(sector_t) > sizeof(u32)).
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
(aka the shifting dance case). Here we have sector_shift = preshift +
1 and
spacing = 2 * hash_spacing
during the computation of nb_zone and curr_sector, but
spacing = hash_spacing
in which_dev() because in the last hunk of the patch for linear.c we
shift down conf->spacing (= 2 * hash_spacing) by one more bit than
in the old code.
Hence in the computation of nb_zone, sz and base have the same value
as before, so nb_zone is not affected. Also curr_sector in the next
hunk stays the same.
In which_dev() the hash table index is computed as
(sector >> sector_shift) / spacing
In view of sector_shift = preshift + 1 and spacing = hash_spacing,
this equals
((sector/2) >> preshift) / hash_spacing
which is the value computed by the old code.

For externally managed metadata, the 'metadata_version' sysfs
attribute is really just a channel for user-space programs to
communicate about how the array is being managed.
It can be useful for this to be changed while the array is active.
Normally changes to metadata_version are not permitted while the array
is active. Change that so that if the metadata is externally managed,
the metadata_version can be changed to a different flavour of external
management.
