commit 21a3c96 uses node_start/end_pfn(nid) for detection start/end
of nodes. But, it's not defined in linux/mmzone.h but defined in
/arch/???/include/mmzone.h which is included only under
CONFIG_NEED_MULTIPLE_NODES=y.Then, we see
mm/page_cgroup.c: In function 'page_cgroup_init':
mm/page_cgroup.c:308: error: implicit declaration of function 'node_start_pfn'
mm/page_cgroup.c:309: error: implicit declaration of function 'node_end_pfn'So, fixiing page_cgroup.c is an idea...
But node_start_pfn()/node_end_pfn() is a very generic macro and
should be implemented in the same manner for all archs.
(m32r has different implementation...)This patch removes definitions of node_start/end_pfn() in each archs
and defines a unified one in linux/mmzone.h. It's not under
CONFIG_NEED_MULTIPLE_NODES, now.A result of macro expansion is here (mm/page_cgroup.c)
for !NUMA
start_pfn = ((&contig_page_data)->node_start_pfn);
end_pfn = ({ pg_data_t *__pgdat = (&contig_page_data); __pgdat->node_start_pfn + __pgdat->node_spanned_pages;});for NUMA (x86-64)
start_pfn = ((node_data[nid])->node_start_pfn);
end_pfn = ({ pg_data_t *__pgdat = (node_data[nid]); __pgdat->node_start_pfn + __pgdat->node_spanned_pages;});Changelog:

The DMA region must be accessible in order for PCI peripheral
drivers to work, the sparc32 has DMA in the normal memory
zone which requires the GRPCI2 to PCI target BARs so that all
kernel low mem (192MB) can be mapped 1:1 to PCI address
space. The GRPCI2 has resizeable target BARs, by default the
first is made 256MB and all other BARs are disabled.I/O space are always located on 0x1000-0x10000, but accessed
through the GRPCI2 PCI I/O Window memory mapped to virtual
address space.Configuration space is accessed through the 64KB GRPCI2 PCI
CFG Window using LDA bypassing the MMU.The GRPCI2 has a single PCI Window for prefetchable and non-
prefetchable address space, it is up to the AHB master
requesting PCI data to determine access type. Memory space
is mapped 1:1.The GRPCI2 core can be configured in 4 different IRQ modes,
where PCI Interrupt, Error Interrupt and DMA Interrupt are
shared on a single IRQ line or at most 5 IRQs are used. The
GRPCI2 can mask/unmask PCI interrupts, Err and DMA in the control
and check status bits which tells us which IRQ really happended.
The GENIRQ layer is used to unmask/mask each individual IRQ
source by creating virtual IRQs and implementing a IRQ chip.The optional DMA functionality of the GRPCI2 is not supported
by this patch.Signed-off-by: Daniel Hellstrom

32bit and 64bit on x86 are tested and working. The rest I have looked
at closely and I can't find any problems.setns is an easy system call to wire up. It just takes two ints so I
don't expect any weird architecture porting problems.While doing this I have noticed that we have some architectures that are
very slow to get new system calls. cris seems to be the slowest where
the last system calls wired up were preadv and pwritev. avr32 is weird
in that recvmmsg was wired up but never declared in unistd.h. frv is
behind with perf_event_open being the last syscall wired up. On h8300
the last system call wired up was epoll_wait. On m32r the last system
call wired up was fallocate. mn10300 has recvmmsg as the last system
call wired up. The rest seem to at least have syncfs wired up which was
new in the 2.6.39.v2: Most of the architecture support added by Daniel Lezcano
v3: ported to v2.6.36-rc4 by: Eric W. Biederman
v4: Moved wiring up of the system call to another patch
v5: ported to v2.6.39-rc6
v6: rebased onto parisc-next and net-next to avoid syscall conflicts.

Rework the sparc mmu_gather usage to conform to the new world order :-)
Sparc mmu_gather does two things:
- tracks vaddrs to unhash
- tracks pages to freeSplit these two things like powerpc has done and keep the vaddrs
in per-cpu data structures and flush them on context switch.The remaining bits can then use the generic mmu_gather.

Adapt new API. Almost change is trivial, most important change are to
remove following like =operator.cpumask_t cpu_mask = *mm_cpumask(mm);
cpus_allowed = current->cpus_allowed;Because cpumask_var_t is =operator unsafe. These usage might prevent
kernel core improvement.No functional change.

This patch implements SMP IPIs on LEON using software generated
IRQs to signal between CPUs.The IPI IRQ number is set by using the ipi_num property in the
device tree, or defaults to 13. LEON SMP systems should reserve
IRQ 13 (and IRQ 15) to Linux in order for the defaults to work.Signed-off-by: Daniel Hellstrom
Signed-off-by: David S. Miller -
The current sparc32 SMP IPI generation is implemented the
cross call function. The cross call function uses IRQ15 the
NMI, this is has the effect that IPIs will interrupt IRQ
critical areas and hang the system. Typically on/after
spin_lock_irqsave calls can be aborted.The cross call functionality must still exist to flush
cache/TLBS.This patch provides CPU models a custom way to implement
generation of IPIs on the generic code's request. The
typical approach is to generate an IRQ for each IPI case.After this patch each sparc32 SMP CPU model needs to
implement IPIs in order to function properly.Signed-off-by: Daniel Hellstrom

This patch adds a multiple message send syscall and is the send
version of the existing recvmmsg syscall. This is heavily
based on the patch by Arnaldo that added recvmmsg.I wrote a microbenchmark to test the performance gains of using
this new syscall:http://ozlabs.org/~anton/junkcode/sendmmsg_test.c
The test was run on a ppc64 box with a 10 Gbit network card. The
benchmark can send both UDP and RAW ethernet packets.64B UDP

to support architectures which can boot on other than CPU0.Sam Ravnborg has written the cleanup parts by extracting
boot_cpu_id from smp_32.c into setup_32.c and cleaned up
sun4d_irq.c.boot_cpu_id was initialized before BSS was cleared in
sun4c_continue_boot, instead boot_cpu_id is set to 0xff to

Introduce:
static __always_inline bool static_branch(struct jump_label_key *key);
instead of the old JUMP_LABEL(key, label) macro.
In this way, jump labels become really easy to use:
Define:
struct jump_label_key jump_key;
Can be used as:
if (static_branch(&jump_key))
do unlikely codeenable/disale via:
jump_label_inc(&jump_key);
jump_label_dec(&jump_key);that's it!
For the jump labels disabled case, the static_branch() becomes an
atomic_read(), and jump_label_inc()/dec() are simply atomic_inc(),
atomic_dec() operations. We show testing results for this change below.Thanks to H. Peter Anvin for suggesting the 'static_branch()' construct.
Since we now require a 'struct jump_label_key *key', we can store a pointer into
the jump table addresses. In this way, we can enable/disable jump labels, in
basically constant time. This change allows us to completely remove the previous
hashtable scheme. Thanks to Peter Zijlstra for this re-write.Testing:
