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.

This reverts commit c9d761b7c4b658a937a941aea2781f511a0ff3ec.
Ben' commit "microblaze/pci: Move the remains of pci_32.c to pci-common.c"
(sha1: bf13a6fa09b8db7f1fd59b5e2ed3674a89a6a25c)
completely removed pci_32.c that's why my fixing commit caused
the problem with merging and need to be revert.

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.

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.

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.

Do not trace arch_local_save_flags(), arch_local_irq_*() and friends.
Although they are marked inline, gcc may still make a function out of
them and add it to the pool of functions that are traced by the function
tracer. This can cause undesirable results (kernel panic, triple faults,
etc).
Add the notrace notation to prevent them from ever being traced.

The kludge in question is undocumented and doesn't work for 32bit
binaries on amd64, sparc64 and s390. Passing (mode_t)-1 as
mode had (since 0.99.14v and contrary to behaviour of any
other Unix, prescriptions of POSIX, SuS and our own manpages)
was kinda-sorta no-op. Note that any software relying on
that (and looking for examples shows none) would be visibly
broken on sparc64, where practically all userland is built
32bit. No such complaints noticed...

d_move and __d_move have some pretty substantial locking requirements,
but they are not clearly documented. Add some comments spelling them
out. Also, document the requirement for the i_mutex of the parent in
d_materialise_unique.

It is better if the selection between the Low power,
and High performance PLL is handled within the codec
driver, not in machine driver(s) to avoid duplicated
code, and also to have consistent tracking of the selected
PLL, and the resulting differences in supported sample
rates.
