[SPARC64]: Use regsets for ELF core dumping.

[SPARC]: Remove PTRACE_SUN* handling.
[SPARC]: Kill DEBUG_PTRACE code.
[SPARC32]: Add user regset support.
[SPARC64]: Add user regsets.
[SPARC64]: Fix booting on non-zero cpu. -
Use cmpxchg_u32 and cmpxchg_u64 for cmpxchg_local and cmpxchg64_local. For other
type sizes, use the new generic cmpxchg_local (disables interrupt).Change:
Since the header depends on local_irqsave/local_irqrestore, it must be
included after their declaration.Actually, being below the
#include should be enough, and on sparc64 it is
included at the beginning of system.h.So it makes sense to move it up for sparc64.

Supporting SunOS ptrace() is pretty pointless and these

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-2.6:
[SPARC64]: Temporarily remove IOMMU merging code.
[SPARC64]: Update defconfig.
[SPARC]: Add new timerfd syscall entries. -
- All implementations can be __devinit
- The function prototypes were in asm/timex.h but they all must be the same,
so create a single declaration in linux/timex.h.- uninline the sparc64 version to match the other architectures
- Don't bother #defining ARCH_HAS_READ_CURRENT_TIMER to a particular value.

Changeset fde6a3c82d67f592eb587be4d12222b0ae6d4321 ("iommu sg merging:
sparc64: make iommu respect the segment size limits") broke sparc64
because whilst it added the segment limiting code to the first pass of
SG mapping (in prepare_sg()) it did not add matching code to the
second pass handling (in fill_sg())As a result the two passes disagree where the segment boundaries
should be, resulting in OOPSes, DMA corruption, and corrupted
superblocks.Signed-off-by: David S. Miller

(with Martin Schwidefsky )
The pgd/pud/pmd/pte page table allocation functions get a mm_struct pointer as
first argument. The free functions do not get the mm_struct argument. This
is 1) asymmetrical and 2) to do mm related page table allocations the mm
argument is needed on the free function as well.[kamalesh@linux.vnet.ibm.com: i386 fix]

A userspace program may wish to set the mark for each packets its send
without using the netfilter MARK target. Changing the mark can be used
for mark based routing without netfilter or for packet filtering.It requires CAP_NET_ADMIN capability.

Sparc64 has a way of providing the base address for the per cpu area of the
currently executing processor in a global register.Sparc64 also provides a way to calculate the address of a per cpu area
from a base address instead of performing an array lookup.Cc: David Miller

- Special consideration for IA64: Add the ability to specify
arch specific per cpu flags- remove .data.percpu attribute from DEFINE_PER_CPU for non-smp case.
The arch definitions are all the same. So move them into linux/percpu.h.
We cannot move DECLARE_PER_CPU since some include files just include
asm/percpu.h to avoid include recursion problems.Cc: Rusty Russell

I included these operations vector cases for situations
where we never need to do anything, the entries aren't
filled in by any implementation, so we OOPS trying to
invoke NULL pointer functions.Really make them NOPs, to fix the bug.

This was caught and identified by Greg Onufer.
Since we setup the 256M/4M bitmap table after taking over the trap
table, it's possible for some 4M mapping to get loaded in the TLB
beforhand which later will be 256M mappings.This can cause illegal TLB multiple-match conditions. Fix this by
setting up the bitmap before we take over the trap table.Next, __flush_tlb_all() was not doing anything on hypervisor
platforms. Fix by adding sun4v_mmu_demap_all() and calling it.Signed-off-by: David S. Miller

This was found by make randconfig
If the kernel .text is very large, the .fixup section branches
are too far away to be relocated correctly.Use "sethi %hi(label), reg; jmpl reg + %lo(label); %g0" sequence
instead of the branch to fix this.There is another case in switch_to() involving a branch, which
is fixed similarly.Signed-off-by: David S. Miller

Add a Kconfig entry which will toggle some sanity checks on the sg
entry and tables.Signed-off-by: Jens Axboe
-
Change the page member of the scatterlist structure to be an unsigned
long, and encode more stuff in the lower bits:- Bits 0 and 1 zero: this is a normal sg entry. Next sg entry is located
at sg + 1.
- Bit 0 set: this is a chain entry, the next real entry is at ->page_link
with the two low bits masked off.
- Bit 1 set: this is the final entry in the sg entry. sg_next() will return
NULL when passed such an entry.It's thus important that sg table users use the proper accessors to get
and set the page member.Signed-off-by: Jens Axboe

dma_cache_(wback|inv|wback_inv) were the earliest attempt on a generalized
cache managment API for I/O purposes. Originally it was basically the raw
MIPS low level cache API exported to the entire world. The API has
suffered from a lack of documentation, was not very widely used unlike it's
more modern brothers and can easily be replaced by dma_cache_sync. So
remove it rsp. turn the surviving bits back into an arch private API, as
discussed on linux-arch.Signed-off-by: Ralf Baechle
