MIPS: Remove asm/user.h
The struct user definition in this file is not used anywhere (the ELF core dumper does not use that format). Therefore, remove the header and instead enable the asm-generic user.h which is an empty header to satisfy a few generic headers which still try to include user.h. Signed-off-by: Alex Smith <alex@alex-smith.me.uk> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/7459/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

/*
|

* 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, NOT the irix-core). 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.
