Eric W. Biederman b05fd35d91 sysctl s390: Remove dead sysctl binary support
Now that sys_sysctl is a generic wrapper around /proc/sys  .ctl_name
and .strategy members of sysctl tables are dead code.  Remove them.

Now that sys_sysctl is a generic wrapper around /proc/sys  .ctl_name
and .strategy members of sysctl tables are dead code.  Remove them.

The deleted strategy routines here surprise me.  ctl_name was
CTL_UNNUMBERED so they would not have been called at all.

Eric W. Biederman da3f6f9b3e sysctl: Introduce a generic compat sysctl sysctl
This uses compat_alloc_userspace to remove the various
hacks to allow do_sysctl to write to throuh oldlenp.

The rest of our mature compat syscall helper facitilies
are used as well to ensure we have a nice clean maintainable
compat syscall that can be used on all architectures.

The motiviation for a generic compat sysctl (besides the
obvious hack removal) is to reduce the number of compat
sysctl defintions out there so I can refactor the
binary sysctl implementation.

ppc already used the name compat_sys_sysctl so I remove the
ppcs version here.

genksyms currently cannot handle complicated types for exported
percpu variables.  Drop this patch for now as it prevents a
module from being loaded on sn2 systems:

 xpc: no symbol version for per_cpu____sn_cnodeid_to_nasid
 xpc: Unknown symbol per_cpu____sn_cnodeid_to_nasid

Russell King 4b46d64165 ARM: ensure initial page tables are setup for SMP systems
Mapping the same memory using two different attributes (memory
type, shareability, cacheability) is unpredictable.  During boot,
we encounter a situation when we're updating the kernel's page
tables which can lead to dirty cache lines existing in the cache
which are subsequently missed.  This causes stack corruption,
and therefore a crash.

Therefore, ensure that the shared and cacheability settings
matches the configuration that will be used later; this together
with the restriction in early_cachepolicy() ensures that we won't
create a mismatch during boot.

Claudio Scordino 6603a4fd51 ARM: 5776/1: Check compiler version and EABI support when adding ARM unwind support.
ARM unwind is known to compile only with EABI and not-buggy compilers.
The problem is not the unwinding information but the -fno-frame-pointer
option added as a result of !CONFIG_FRAME_POINTER.  Now we check the
compiler and raise a #warning in case of wrong compiler.

Manuel Lauss 44f2c586a3 MIPS: Alchemy: Fix hang with high-frequency edge interrupts
The handle_edge_irq() flowhandler disables edge int sources which occur
too fast (i.e. another edge comes in before the irq handler function
had a chance to finish).  Currently, the mask_ack() callback does not
ack the edges in hardware, leading to an endless loop in the flowhandler
where it tries to shut up the irq source.

When I rewrote the alchemy IRQ code  I wrongly assumed the mask_ack()
callback was only used by the level flowhandler, hence it omitted the
(at the time pointless) edge acks.  Turned out I was wrong; so here
is a complete mask_ack implementation for Alchemy IC, which fixes
the above mentioned problem.
