arch: remove blackfin port

2018-03-16T09:55:47+00:00

The Analog Devices Blackfin port was added in 2007 and was rather
active for a while, but all work on it has come to a standstill
over time, as Analog have changed their product line-up.

Aaron Wu confirmed that the architecture port is no longer relevant,
and multiple people suggested removing blackfin independently because
of some of its oddities like a non-working SMP port, and the amount of
duplication between the chip variants, which cause extra work when
doing cross-architecture changes.

blackfin, m68k: Fix flat_set_persistent() for unsigned long to u32 changes

2017-07-16T16:24:06+00:00

Several variables had their types changed from unsigned long to u32, but
the arch-specific implementations of flat_set_persistent() weren't
updated, leading to compiler warnings on blackfin and m68k:

    fs/binfmt_flat.c: In function ‘load_flat_file’:
    fs/binfmt_flat.c:799: warning: passing argument 2 of ‘flat_set_persistent’ from incompatible pointer type

Fixes: 468138d78510688f ("binfmt_flat: flat_{get,put}_addr_from_rp() should be able to fail")

binfmt_flat: flat_{get,put}_addr_from_rp() should be able to fail

2017-07-03T22:44:02+00:00

on MMU targets EFAULT is possible here.  Make both return 0 or error,
passing what used to be the return value of flat_get_addr_from_rp()
by reference.

Blackfin: mass clean up of copyright/licensing info

2009-10-07T08:36:26+00:00

Bill Gatliff & David Brownell pointed out we were missing some
copyrights, and licensing terms in some of the files in
./arch/blackfin, so this fixes things, and cleans them up.

It also removes:
 - verbose GPL text(refer to the top level ./COPYING file)
 - file names (you are looking at the file)
 - bug url (it's in the ./MAINTAINERS file)
 - "or later" on GPL-2, when we did not have that right

It also allows some Blackfin-specific assembly files to be under a BSD
like license (for people to use them outside of Linux).

flat: fix data sections alignment

2009-05-29T15:40:02+00:00

The flat loader uses an architecture's flat_stack_align() to align the
stack but assumes word-alignment is enough for the data sections.

However, on the Xtensa S6000 we have registers up to 128bit width
which can be used from userspace and therefor need userspace stack and
data-section alignment of at least this size.

This patch drops flat_stack_align() and uses the same alignment that
is required for slab caches, ARCH_SLAB_MINALIGN, or wordsize if it's
not defined by the architecture.

It also fixes m32r which was obviously kaput, aligning an
uninitialized stack entry instead of the stack pointer.
