[PATCH] kdump: export per cpu crash notes pointer through sysfs

- Kexec on panic functionality allocates memory for saving cpu registers in
  case of system crash event.  Address of this allocated memory needs to be
  exported to user space, which is used by kexec-tools.

- Previously, a single /sys/kernel/crash_notes entry was being exported as
  memory allocated was a single continuous array.  Now memory allocation being
  dyanmic and per cpu based, address of per cpu buffer is exported through
  "/sys/devices/system/cpu/cpuX/crash_notes"

[PATCH] kdump: dynamic per cpu allocation of memory for saving cpu registers

- In case of system crash, current state of cpu registers is saved in memory
  in elf note format.  So far memory for storing elf notes was being allocated
  statically for NR_CPUS.

- This patch introduces dynamic allocation of memory for storing elf notes.
  It uses alloc_percpu() interface.  This should lead to better memory usage.

- Introduced based on Andi Kleen's and Eric W. Biederman's suggestions.

- This patch also moves memory allocation for elf notes from architecture
  dependent portion to architecture independent portion.  Now crash_notes is
  architecture independent.  The whole idea is that size of memory to be
  allocated per cpu (MAX_NOTE_BYTES) can be architecture dependent and
  allocation of this memory can be architecture independent.

[CRYPTO] Allow AES C/ASM implementations to coexist

As the Crypto API now allows multiple implementations to be registered
for the same algorithm, we no longer have to play tricks with Kconfig
to select the right AES implementation.

This patch sets the driver name and priority for all the AES
implementations and removes the Kconfig conditions on the C implementation
for AES.

[CRYPTO] Allow multiple implementations of the same algorithm

This is the first step on the road towards asynchronous support in
the Crypto API.  It adds support for having multiple crypto_alg objects
for the same algorithm registered in the system.

For example, each device driver would register a crypto_alg object
for each algorithm that it supports.  While at the same time the
user may load software implementations of those same algorithms.

Users of the Crypto API may then select a specific implementation
by name, or choose any implementation for a given algorithm with
the highest priority.

The priority field is a 32-bit signed integer.  In future it will be
possible to modify it from user-space.

This also provides a solution to the problem of selecting amongst
various AES implementations, that is, aes vs. aes-i586 vs. aes-padlock.
