Add patches for versions that didn't have them - patches updated/retired as necessary. Also, disallow 2.12.2 for architectures in ports - this version did not have ports addon. Signed-off-by: Alexey Neyman <stilor@att.net>

+/* 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.
