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.

/*

|
* 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). The 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 handy at some point. All of the registers
|
|
* are stored as part of the upage. The upage should always be
|
|
* only one page long.
|
|
* data: The data segment follows next. We use current->end_text to
|
|
* current->brk to pick up all of the user variables, plus any memory
|
|
* that may have been sbrk'ed. 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 usp to
|
|
* current->start_stack, so we round each of these in order to be able
|
|
* to write an integer number of pages.
