scripts: improve checkstack
Cleanup checkstack script:
  * Turn on strict checking
  * Fix resulting error message because the declaration syntax
    was incorrect.
  * Remove incorrect and misleading use of prototype
     - prototype not required for this type of sort function
       because $a and $b are being used in this contex
     - if prototype was being used it should be for both arguments
  * Use closure for sort function

[S390] Fix checkstack for s390

insruction lay for stack register handling. This patch adopts checkstack

fix checkstack.pl arch detection
uname -m was leaving a newline in $arch, and not passing the tests.

Also, printing the unknown arch on failure is probably helpful.

find dynamic stack allocations in checkstack.pl
Currently, checkstack.pl only looks for fixed subtractions from the stack
pointer.  However, things like this:

void function(int size)
{
        char stackbuster[size << 2];
...

are certainly worth pointing out, I think.

This could perhaps be done more cleanly, and the following patch only
adds "dynamic" REs for x86 and x86_64, but it works:

0x00b0 crypto_cbc_decrypt_inplace [cbc]:                Dynamic (%rax)
0x00ad crypto_pcbc_decrypt_inplace [pcbc]:              Dynamic (%rax)
0x02f6 crypto_pcbc_encrypt_inplace [pcbc]:              Dynamic (%rax)
0x036c _crypto_xcbc_digest_setkey [xcbc]:               Dynamic (%rax)
...

(Inspired by Keith Owens' old stack-check script)

Claim maintainership for block2mtd and update email addresses
I have been prime author and maintainer of block2mtd from day one, but
neither MAINTAINERS nor the module source makes this fact clear.  And while
I'm at it, update my email addresses tree-wide, as the old address
currently bounces and change my name to "joern" as unicode will likely
continue to cause trouble until the end of this century.

[PATCH] checkstack: print module names
Finding "init_module" high stack usage problems is challenging when there
are over 1600 "init_module" functions in the kernel tree, so make
checkstack.pl print out the filename where the stack usage occurs.  This is
useful for code built as loadable modules.

For built-in code, it just prints the kernel image file name, like
"vmlinux".  Examples:

(before patch:)
0x0000000d callback:					1928
0xffffffff81678c09 huft_build:				1560
0x0018 init_module:					1512

(after patch:)
0x0000000d callback [divacapi]:				1928
0xffffffff81678c09 huft_build [vmlinux]:		1560
0x0018 init_module [hdaps]:				1512

Also change one if-series to use elsif to cut down on unneeded tests.

Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
