The MMCI driver, when used with a Device Tree described device, relies
on the "vmmc" voltage regulator supply to set the OCR register voltage bits,
using MMC core's mmc_regulator_get_supply() function.
Without the regulator framework present there are no valid operating
voltages reported and the device initialisation fails:
mmci-pl18x 10005000.mmci: No vmmc regulator found
mmci-pl18x 10005000.mmci: no support for card's volts
mmc0: error -22 whilst initialising SD card

Just move to drivers as further clean-up can now happen there
finally.
Let's also add Roger and me to the MAINTAINERS so we get
notified for any patches related to GPMC.

This will us allow to just move gpmc.c to live under drivers
in the next patch.
Note that we now also remove the omap specific check for the
initcall. That's OK as gpmc_probe() checks for the pdata
and bails out for other platforms compiled in.
Also the postcore_initcall() maybe possible to change to
just regular module_init(), but let's do that in separate
patch after the move to drivers is done.

Now, with the CLCD DT support available, there is no

Removed, together with "some" supporting code. It was

it is low cost (?) SoC targeted for market in China and India which
trying to compete with AT91SAM9G25.
Here is some info:
http://www.alphascale.com/index.asp?ics/615.html
One of products:
http://www.aliexpress.com/store/product/2014-hot-sales-FREE-SHIPPING-new-Purple-core-ARM9-development-board-ASM9260T-SDRAM-power-line/433637_1931495721.html
In some cases this SoC looks similar to iMX23/iMX28. But currently it makes no
sense to merge mach code of this devices. Especially because most differences
are already collected mach-mxs folder.

This patch adapts handling of local interrupts to be more compliant with
the z/Architecture Principles of Operation and introduces a data
structure
which allows more efficient handling of interrupts.
* get rid of li->active flag, use bitmap instead
* Keep interrupts in a bitmap instead of a list
* Deliver interrupts in the order of their priority as defined in the
PoP
* Use a second bitmap for sigp emergency requests, as a CPU can have
one request pending from every other CPU in the system.

When injecting a floating interrupt and no CPU is idle we
kick one CPU to do an external exit. In case of I/O we
should trigger an I/O exit instead. This does not matter
for Linux guests as external and I/O interrupts are
enabled/disabled at the same time, but play safe anyway.
The same holds true for machine checks. Since there is no
special exit, just reuse the generic stop exit. The injection
code inside the VCPU loop will recheck anyway and rearm the
proper exits (e.g. control registers) if necessary.

A couple of our interception handlers rewind the PSW to the beginning
of the instruction to run the intercepted instruction again during the
next SIE entry. This normally works fine, but there is also the
possibility that the instruction did not get run directly but via an
EXECUTE instruction.
In this case, the PSW does not point to the instruction that caused the
interception, but to the EXECUTE instruction! So we've got to rewind the
PSW to the beginning of the EXECUTE instruction instead.
This is now accomplished with a new helper function kvm_s390_rewind_psw().

This patch includes two small fixes for the PFMF handler: First, the
start address for PFMF has to be masked according to the current
addressing mode, which is now done with kvm_s390_logical_to_effective().
Second, the protection exceptions have a lower priority than the
specification exceptions, so the check for low-address protection
has to be moved after the last spot where we inject a specification
exception.

secure_computing() is called first in syscall_trace_enter() so that
a system call will be aborted quickly without doing succeeding syscall
tracing if seccomp rules want to deny that system call.
On compat task, syscall numbers for system calls allowed in seccomp mode 1
are different from those on normal tasks, and so _NR_seccomp_xxx_32's need
to be redefined.

If tracer modifies a syscall number to -1, this traced system call should
be skipped with a return value specified in x0.
This patch implements this semantics.
Please note:
* syscall entry tracing and syscall exit tracing (ftrace tracepoint and
audit) are always executed, if enabled, even when skipping a system call
(that is, -1).
In this way, we can avoid a potential bug where audit_syscall_entry()
might be called without audit_syscall_exit() at the previous system call
being called, that would cause OOPs in audit_syscall_entry().

This regeset is intended to be used to get and set a system call number
while tracing.
There was some discussion about possible approaches to do so:
(1) modify x8 register with ptrace(PTRACE_SETREGSET) indirectly,
and update regs->syscallno later on in syscall_trace_enter(), or
(2) define a dedicated regset for this purpose as on s390, or
(3) support ptrace(PTRACE_SET_SYSCALL) as on arch/arm
Thinking of the fact that user_pt_regs doesn't expose 'syscallno' to
tracer as well as that secure_computing() expects a changed syscall number,
especially case of -1, to be visible before this function returns in
syscall_trace_enter(), (1) doesn't work well.
We will take (2) since it looks much cleaner.

Simplify cpu_relax() to a simple barrier(). Performance wise this doesn't
seem to make any big difference anymore, since nearly all lock variants
have directed yield semantics in the meantime.
Also this makes s390 behave like all other architectures.

The common code ftrace_return_address(n), which is just a wrapper for
__builtin_return_address(n), will only work for n > 0 if CONFIG_FRAME_POINTER
is set to 'y'. Otherwise it will return 0.
Since on s390 we will never have that config option set to 'y'
ftrace_return_address() won't work at all for n > 0.
Luckily we always compile the kernel with -mkernel-backchain which
in turn means that __builtin_return_address(n) will always work.
So let ftrace_return_address(n) map to __builtin_return_address(n).
