Revision 0da2f0f164f098bb4447c714b552ac1681b2d6e8 authored by Yoann Padioleau on 06 July 2007, 09:39:56 UTC, committed by Linus Torvalds on 06 July 2007, 17:23:43 UTC
In 7d12e780e003f93433d49ce78cfedf4b4c52adc5 David Howells performed this evolution: "IRQ: Maintain regs pointer globally rather than passing to IRQ handlers" He correctly updated many of the function definitions that were using this extra regs pointer parameter but forgot to update some caller sites of those functions. The reason the modifications was not properly done on all drivers is that some drivers were rarely compiled because they are for AMIGA, or that some code sites were inside #ifdefs where the option is not set or inside #if 0. Here is the semantic patch that found the occurences and fixed the problem. @ rule1 @ identifier fn; identifier irq, dev_id; typedef irqreturn_t; @@ static irqreturn_t fn(int irq, void *dev_id) { ... } @@ identifier rule1.fn; expression E1, E2, E3; @@ fn(E1, E2 - ,E3 ) Signed-off-by: Yoann Padioleau <padator@wanadoo.fr> Cc: "David S.

/*
* 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 osf-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.
