Initial fix for making sure that we can access percpu variables
in all C code (commit: 10617bbe84628eb18ab5f723d3ba35005adde143)
inadvertantly allocated the memory in the "percpu" section of
the vmlinux ELF executable. This confused kexec/dump.

bte.h expects a #define of L1_CACHE_MASK which is currently only
in bte.c. This small patch gets bte.h to include cleanly and makes
BTE_UNALIGNED_COPY not report errors.

Broke the non modular builds by moving an essential function into
modules.c. Fix this by moving it out again and into asm/sections.h as
an inline. To do this, the definitions of struct fdesc and struct
got_val have been lifted out of modules.c and put in asm/elf.h where
they belong.

It was introduced by "vsprintf: add support for '%pS' and '%pF' pointer
formats" in commit 0fe1ef24f7bd0020f29ffe287dfdb9ead33ca0b2. However,
the current way its coded doesn't work on parisc64. For two reasons: 1)
parisc isn't in the #ifdef and 2) parisc has a different format for
function descriptors
Make dereference_function_descriptor() more accommodating by allowing
architecture overrides. I put the three overrides (for parisc64, ppc64
and ia64) in arch/kernel/module.c because that's where the kernel
internal linker which knows how to deal with function descriptors sits.

Some ia64 systems produce several repeats of kernel messages like this:
kernel unaligned access to 0xe000000644220466, ip=0xa000000100516fa1
This was tracked to ide code using the __cmd[] field in "struct request"
via the __outsw() function. __cmd[] is a char array, so is not guaranteed
to be properly aligned when accessed as words.

Rename KEXEC_CONTROL_CODE_SIZE to KEXEC_CONTROL_PAGE_SIZE, because control
page is used for not only code on some platform. For example in kexec
jump, it is used for data and stack too.

of the obsolete BCD2BIN/BIN2BCD macros.

After moving the the include files there were a few clean-ups:
1) Some files used #include <asm-ia64/xyz.h>, changed to <asm/xyz.h>
2) Some comments alerted maintainers to look at various header files to
make matching updates if certain code were to be changed. Updated these
comments to use the new include paths.
3) Some header files mentioned their own names in initial comments. Just
deleted these self references.
