Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/vapier/blackfin

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/vapier/blackfin:
  Blackfin: convert page/tlb to asm-generic
  Blackfin: convert types to asm-generic
  Blackfin: convert irq/process to asm-generic
  Blackfin: convert signal/mmap to asm-generic
  Blackfin: convert locking primitives to asm-generic
  Blackfin: convert termios to asm-generic
  Blackfin: convert simple headers to asm-generic
  Blackfin: convert socket/poll to asm-generic
  Blackfin: convert user/elf to asm-generic
  Blackfin: convert shm/sysv/ipc to asm-generic
  Blackfin: convert asm/ioctls.h to asm-generic/ioctls.h
  Blackfin: only build irqpanic.c when needed
  Blackfin: pull in asm/io.h in ksyms for prototypes
  Blackfin: use common test_bit() rather than __test_bit()

/* Core file format: The core file is written in such a way that gdb
can understand it and provide useful information to the user (under
linux we use the 'trad-core' bfd). There are quite a number of
obstacles to being able to view the contents of the floating point
registers, and until these are solved you will not be able to view the
contents of them. Actually, you can read in the core file and look at
the contents of the user struct to find out what the floating point
registers contain.
The actual file contents are as follows:
UPAGE: 1 page consisting of a user struct that tells gdb what is present
in the file. Directly after this is a copy of the task_struct, which
is currently not used by gdb, but it may come in useful at some point.
All of the registers are stored as part of the upage. The upage should
always be only one page.
DATA: The data area is stored. We use current->end_text to
current->brk to pick up all of the user variables, plus any memory
that may have been malloced. No attempt is made to determine if a page
is demand-zero or if a page is totally unused, we just cover the entire
range. All of the addresses are rounded in such a way that an integral
number of pages is written.
STACK: We need the stack information in order to get a meaningful
backtrace. We need to write the data from (esp) to
current->start_stack, so we round each of these off in order to be able
to write an integer number of pages.
The minimum core file size is 3 pages, or 12288 bytes.
