We have had complaints where a threaded application is left in a bad state
after one of it's threads is killed when we hit a VM: out_of_memory
condition.Killing just one of the process threads can leave the application in a bad
state, whereas killing the entire process group would allow for the
application to restart, or be otherwise handled, and makes it very obvious
that something has gone wrong.This change allows the entire process group to be taken down, rather
than just the one thread.Signed-off-by: Will Schmidt

Enable virtual memmap support for SPARSEMEM on PPC64 systems. Slice a 16th
off the end of the linear mapping space and use that to hold the vmemmap.
Uses the same size mapping as uses in the linear 1:1 kernel mapping.[pbadari@gmail.com: fix warning]

Equip IA64 sparsemem with a virtual memmap. This is similar to the existing
CONFIG_VIRTUAL_MEM_MAP functionality for DISCONTIGMEM. It uses a PAGE_SIZE
mapping.This is provided as a minimally intrusive solution. We split the 128TB
VMALLOC area into two 64TB areas and use one for the virtual memmap.This should replace CONFIG_VIRTUAL_MEM_MAP long term.

x86_64 uses 2M page table entries to map its 1-1 kernel space. We also
implement the virtual memmap using 2M page table entries. So there is no
additional runtime overhead over FLATMEM, initialisation is slightly more
complex. As FLATMEM still references memory to obtain the mem_map pointer and
SPARSEMEM_VMEMMAP uses a compile time constant, SPARSEMEM_VMEMMAP should be
superior.With this SPARSEMEM becomes the most efficient way of handling virt_to_page,
pfn_to_page and friends for UP, SMP and NUMA on x86_64.[apw@shadowen.org: code resplit, style fixups]

Convert the common vmemmap population into initialisation helpers for use by
architecture vmemmap populators. All architecture implementing the
SPARSEMEM_VMEMMAP variant supply an architecture specific vmemmap_populate()
initialiser, which may make use of the helpers.This allows us to clean up and remove the initialisation Kconfig entries.
With this patch there is a single SPARSEMEM_VMEMMAP_ENABLE Kconfig option to
indicate use of that variant.Signed-off-by: Andy Whitcroft

SPARSEMEM is a pretty nice framework that unifies quite a bit of code over all
the arches. It would be great if it could be the default so that we can get
rid of various forms of DISCONTIG and other variations on memory maps. So far
what has hindered this are the additional lookups that SPARSEMEM introduces
for virt_to_page and page_address. This goes so far that the code to do this
has to be kept in a separate function and cannot be used inline.This patch introduces a virtual memmap mode for SPARSEMEM, in which the memmap
is mapped into a virtually contigious area, only the active sections are
physically backed. This allows virt_to_page page_address and cohorts become
simple shift/add operations. No page flag fields, no table lookups, nothing
involving memory is required.The two key operations pfn_to_page and page_to_page become:
#define __pfn_to_page(pfn) (vmemmap + (pfn))
#define __page_to_pfn(page) ((page) - vmemmap)By having a virtual mapping for the memmap we allow simple access without
wasting physical memory. As kernel memory is typically already mapped 1:1
this introduces no additional overhead. The virtual mapping must be big
enough to allow a struct page to be allocated and mapped for all valid
physical pages. This vill make a virtual memmap difficult to use on 32 bit
platforms that support 36 address bits.However, if there is enough virtual space available and the arch already maps
its 1-1 kernel space using TLBs (f.e. true of IA64 and x86_64) then this
technique makes SPARSEMEM lookups even more efficient than CONFIG_FLATMEM.
FLATMEM needs to read the contents of the mem_map variable to get the start of
the memmap and then add the offset to the required entry. vmemmap is a
constant to which we can simply add the offset.This patch has the potential to allow us to make SPARSMEM the default (and
even the only) option for most systems. It should be optimal on UP, SMP and
NUMA on most platforms. Then we may even be able to remove the other memory
models: FLATMEM, DISCONTIG etc.[apw@shadowen.org: config cleanups, resplit code etc]

We have flags to indicate whether a section actually has a valid mem_map
associated with it. This is never set and we rely solely on the present bit
to indicate a section is valid. By definition a section is not valid if it
has no mem_map and there is a window during init where the present bit is set
but there is no mem_map, during which pfn_valid() will return true
incorrectly.Use the existing SECTION_HAS_MEM_MAP flag to indicate the presence of a valid
mem_map. Switch valid_section{,_nr} and pfn_valid() to this bit. Add a new
present_section{,_nr} and pfn_present() interfaces for those users who care to
know that a section is going to be valid.[akpm@linux-foundation.org: coding-syle fixes]

architectures. This should facilitate the removal of the bespoke
implementations from the architectures. This also brings performance
improvements for most architecture making sparsmem vmemmap the more desirable
memory model. The ultimate aim of this work is to expand sparsemem support to
encompass all the features of the other memory models. This could allow us to
drop support for and remove the other models in the longer term.Below are some comparitive kernbench numbers for various architectures,
comparing default memory model against SPARSEMEM VMEMMAP. All but ia64 show
marginal improvement; we expect the ia64 figures to be sorted out when the
larger mapping support returns.x86-64 non-NUMA

x86(-64) are the last architectures still using the page fault notifier
cruft for the kprobes page fault hook. This patch converts them to the
proper direct calls, and removes the now unused pagefault notifier bits
aswell as the cruft in kprobes.c that was related to this mess.I know Andi didn't really like this, but all other architecture maintainers
agreed the direct calls are much better and besides the obvious cruft
removal a common way of dealing with kprobes across architectures is
important aswell.[akpm@linux-foundation.org: build fix]

This is from an earlier message from 'Christoph Lameter':
cpu_core_map is currently an array defined using NR_CPUS. This means that
we overallocate since we will rarely really use maximum configured cpu.If we put the cpu_core_map into the per cpu area then it will be allocated
for each processor as it comes online.This means that the core map cannot be accessed until the per cpu area
has been allocated. Xen does a weird thing here looping over all processors
and zeroing the masks that are not yet allocated and that will be zeroed
when they are allocated. I commented the code out.Signed-off-by: Christoph Lameter

Recently I've been trying to get working PCMCIA interface on H5000 ipaq
series, using dual PCMCIA sleeve. So far things work correctly, but I had
to do one modification to drivers/pcmcia/pxa2xx_base.c to get the interface
working with orinoco gold PCMCIA card (wired pcnet_cs ethernet card worked
even without this modification).The issue has something to do with assert time on PCMCIA bus, but I'm not
really sure what -- I found the working value just by trial&error approach.
I'm not sure how is the assert value in pxa2xx_mcxx_asst calculated (I
know, simple formula, but the reason why is it calculated that way is not
obvious for me), neither that my modification is correct. It just works
with iPAQ.Cc: Russell King

usually see the last thing that happened before the lights went out which is
usually a valuable clue.[akpm@linux-foundation.org: not all architectures implement CONFIG_HZ]
