The nfsservctl system call is now gone, so we should remove all
linkage for it.

  microblaze: PCI fix typo fault in of_node pointer moving into pci_bus
  microblaze: Add support for early console on mdm
  microblaze: Simplify early console binding from DT
  microblaze: Get early printk console earlier
  microblaze: Standardise cpuinfo output for cache policy
  microblaze: Unprivileged stream instruction awareness
  microblaze: trivial: Fix typo fault

  microblaze: Remove duplicated prototype of start_thread()
  microblaze: Fix unaligned value saving to the stack for system with MMU
  microblaze/irqs: Do not trace arch_local_{*,irq_*} functions

When interrupt controller uses 32 interrupts lines the kernel
show error message about mismatch in kind-of-intr parameter
because it exceeds u32. Recast fixs this issue.

Support mdm early console:
 - extend time for retries
 - add mdm compatible property

Signed-off-by: Michal Simek <monstr@monstr.eu>

Recognize early Linux console from chosen - linux,stdout-path
instead of detecting the first console with appropriate
compatible strings.
This patch solved the problem on system with multiple
consoles.

1. Register early console as standard console
2. Enable CON_BOOT console flag to ensure auto-unregistering by the kernel
3. remap_early_printk function remap physical console baseaddr to virtual space

Usage specific function for console remap is done after memory initialization
with IRQ turn off that's why there is not necessary to protect it.

The reason for remapping is that the kernel use TLB 63 for 1:1 address mapping
to be able to use console in very early boot-up phase. But allocating one TLB
just for console caused performance degression that's why ioremaps create new
mapping and TLB 63 is automatically released and ready to use.

The current cpuinfo output for the cache policy has no leading tag:, making
it difficult to parse.  Add a leaning "Dcache-policy:" tag to this field.

Add cpuinfo support for the new MicroBlaze option permitting userspace
(unprivileged) access to the streaming instructions (FSL / AXI-stream).

Emit a noisy warning at bootup if this is enabled, because bad user code
can potentially lockup the CPU.

The address limit is already set in flush_old_exec() so this
set_fs(USER_DS) is redundant.

Several registers weren't saved correctly to the stack.

Unaligned expection for system with MMU stores
value in ex_tmp_data_loc_X address which is load to registers r3.
The next step is to move this value from r3 to a destination
register which caused unaligned exception. For several registers
this value was directly moved to the register.

For example for r28:
by "or r28, r0, r3"

but register r28 was rewritten when kernel returns from exception
handler by value saved on stack.

This patch changed r3 saving to the correct address on the stack.
For example for r28:
by "swi r3, r1, 4 * 28"

When kernel returns from the exception handler, correct value is restored.
