As far as I can tell the only reason microblaze has
__ARCH_WANT_INTERRUPTS_ON_CTXSW is because it initializes new task state
with interrupts enabled so that on switch_to() interrupts get enabled.So change copy_thread() to clear MSR_IE instead of set it, this will
ensure switch_to() will always keep IRQs disabled.The scheduler will disable IRQs when taking rq->lock in schedule() and
enable IRQs in finish_lock_switch() after its done its magic.This leaves ARM the only __ARCH_WANT_INTERRUPTS_ON_CTXSW user.

There is the problem with bit OR (|) because for
some combination is addr | size | addr+size equal
to seq.For standard kernel setting (kernel starts at 0xC0000000)
is seq for user space 0xBFFFFFFF and everything below
this limit is fine.But even address 0xBFFFFFFF is fine because it
is below kernel space.Signed-off-by: Andrew Fedonczuk

Documentation files, in comments, etc.). These broken references are
caused by typo's in the references, and by renames or removals of the

Support mdm early console:
- extend time for retries
- add mdm compatible propertySigned-off-by: Michal Simek
-
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.Signed-off-by: Michal Simek
-
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 spaceUsage 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.Signed-off-by: Michal Simek

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.
