The address where the ELF core header is stored is passed to the secondary
kernel as a kernel command line option. The memory area for this header is
also marked as a separate EFI memory descriptor on ia64.
The separate EFI memory descriptor is at the moment of the type
EFI_UNUSABLE_MEMORY. With such a type the secondary kernel skips over the
entire memory granule (config option, 16M or 64M) when detecting memory.
If we are lucky we will just lose some memory, but if we happen to have
data in the same granule (such as an initramfs image), then this data will
never get mapped and the kernel bombs out when trying to access it.
So this is an attempt to fix this by changing the EFI memory descriptor
type into EFI_LOADER_DATA. This type is the same type used for the kernel
data and for initramfs. In the secondary kernel we then handle the ELF
core header data the same way as we handle the initramfs image.
This patch contains the kernel changes to make this happen. Pretty
straightforward, we reserve the area in reserve_memory(). The address for
the area comes from the kernel command line and the size comes from the
specialized EFI parsing function vmcore_find_descriptor_size().
The kexec-tools-testing code for this can be found here:

Perfmon associates vmalloc()ed memory with a file descriptor, and installs
a vma mapping that memory. Unfortunately, the vm_file field is not filled
in, so processes with mappings to that memory do not prevent the file from
being closed and the memory freed. This results in use-after-free bugs and
multiple freeing of pages, etc.
I saw this bug on an Altix on SLES9. Haven't reproduced upstream but it
looks like the same issue is there.

Always build ia64 xor.o because multiple config options now depend on it.
Necessary to build .20-mm* on ia64 when, e.g., CONFIG_ASYNC_TX_DMA is
defined. Don't know if '_ASYNC_TX_DMA makes sense on ia64. If not, maybe
Kconfig should preclude it.
Could have defined a Kconfig option that defaults to true if MD_RAID456 ||
ASYNC_TX_DMA to control building of xor.o, but xor.o is only 848 bytes and
this IS ia64...

Make saved_max_pfn point to max_pfn of entire system.
Without this patch is so that vmcore is zero length on ia64. This is
because saved_max_pfn was wrongly being set to the max_pfn of the crash
kernel's address space, rather than the max_pfg on the physical memory of
the machine - the whole purpose of vmcore is to access physical memory that
is not part of the crash kernel's addresss space.

Provide a module param "pool_mode" for sunrpc.ko which allows a sysadmin to
choose the mode for mapping NFS thread service pools to CPUs. Values are:
auto choose a mapping mode heuristically
global (default, same as the pre-2.6.19 code) a single global pool
percpu one pool per CPU
pernode one pool per NUMA node
Note that since 2.6.19 the hardcoded behaviour has been "auto", this patch
makes the default "global".
The pool mode can be changed after boot/modprobe using /sys, if the NFS and
lockd services have been shut down. A useful side effect of this change is to
fix a small memory leak when unloading the module.

server
When the last thread of nfsd exits, it shuts down all related sockets. It
currently uses svc_close_socket to do this, but that only is immediately
effective if the socket is not SK_BUSY.
If the socket is busy - i.e. if a request has arrived that has not yet been
processes - svc_close_socket is not effective and the shutdown process spins.
So create a new svc_force_close_socket which removes the SK_BUSY flag is set
and then calls svc_close_socket.
Also change some open-codes loops in svc_destroy to use
list_for_each_entry_safe.

The sunrpc server code needs to know the source and destination address for
UDP packets so it can reply properly. It currently copies code out of the
network stack to pick the pieces out of the skb. This is ugly and causes
compile problems with the IPv6 stuff.
So, rip that out and use recv_msg instead. This is a much cleaner interface,
but has a slight cost in that the checksum is now checked before the copy, so
we don't benefit from doing both at the same time. This can probably be
fixed.

initramfs ended up depending on BLOCK:
INITRAMFS_SOURCE <-- BLK_DEV_INITRD <-- BLOCK
This inhibits use of customized-initramfs-over-ramfs without block layer
(ramfs would still be enabled), useful in embedded applications.
Move BLK_DEV_INITRD out of 'drivers/block/Kconfig' and into 'init/Kconfig',
make it unconditional.

This patch changes the way we determine if a logical volume is larger than
2TB.
The original test looked for a total_size of 0. Originally we added 1 to the
total_size. That would make our read_capacity return size 0 for >2TB lv's.
We assumed that we could not have a lv size of 0 so it seemed OK until we were
in a clustered system. The backup node would see a size of 0 due to the
reservation on the drive. That caused the driver to switch to 16-byte CDB's
which are not supported on older controllers. After that everything was
broken.
It may seem petty but I don't see the value in trying to determine if the LBA
is beyond the 2TB boundary. That's why when we switch we use 16-byte CDB's
for all read/write operations. Please consider this for inclusion.

rcutorture's module parameters currently use permissions of 0, so they
don't show up in /sys/module/rcutorture/parameters. Change the permissions
on all module parameters to world-readable (0444).
rcutorture does all of its initialization and thread startup when loaded
and relies on the parameters not changing during execution, so they should
not permit writing. However, reading seems fine.

I've only seen this on x86_64.
The vsyscall state only gets updated when a timer interrupts comes in. So
if the time is set long before the next timer, there will be a period when
a gettimeofday() won't reflect the correct time.
I added an explicit update_vsyscall() during the settimeofday(), that way
the vsyscall state doesn't get stale.

The TIMER_SOFTIRQ runs the hrtimers during bootup until a usable
clocksource and clock event sources are registered. The switch to high
resolution mode happens inside of the TIMER_SOFTIRQ, but runs the softirq
afterwards. That way the tick emulation timer, which was set up in the
switch to highres might be executed in the softirq context, which is a BUG.
The rbtree has not to be touched by the softirq after the highres switch.
This BUG was observed by Andres Salomon, who provided the information to
debug it.
Return early from the softirq, when the switch was sucessful.

Prior to commit 95492e4646e5de8b43d9a7908d6177fb737b61f0 ([PATCH] x86:
rewrite SMP TSC sync code), the headers in asm-i386 did not really require
anything in include/asm-x86_64. This means that distributions such as
fedora did not include asm-x86_64 in kernel-devel headers for i386. Ingo's
commit changed that, and broke things. This is easy enough to hack around
in package builds by just including asm-x86_64 on i386, but that's kind of
annoying. If anything, x86_64 should depend upon i386, not the other way
around.
This patch changes it so that asm-x86_64/tsc.h includes asm-i386/tsc.h,
rather than vice-versa.
