microblaze: Fix __futex_atomic_op macro register usage

2013-09-10T00:57:39+00:00

commit 8cf662ed3ef190fddc186bb5b1cd75eb3880d5a9 upstream.

Old Microblaze toolchain supported "b" contstrains for
all register but it always points to general purpose reg.
New Microblaze toolchain is more strict in this
and general purpose register should be used there "r".

microblaze: bury asm/namei.h

2011-11-21T21:48:28+00:00

altroot support has been gone for years, along with arch/*/asm/namei.h;
looks like a dummy survivor that sat it out in microblaze tree...

microblaze: Remove __ARCH_WANT_INTERRUPTS_ON_CTXSW usage

2011-10-14T10:28:42+00:00

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.

include/linux/skbuff.h.

microblaze: Switch ELF_ARCH code to 189

2011-10-14T10:24:31+00:00

Switch arch code to 189, the registered code in the upstream
version of binutils. Continue to accept the experimental 0xbaab.

microblaze: Moved __dma_sync() to dma-mapping.h

2011-10-14T10:24:29+00:00

__dma_sync_page() was replaced by __dma_sync(), and parameters of calls to
the new function were adjusted to match __dma_sync()'s format.

microblaze: Fix access_ok macro

2011-10-14T10:24:27+00:00

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.
