module: remove mod arg from module_free, rename module_memfree().

2015-01-20T01:08:33Z

Nothing needs the module pointer any more, and the next patch will call it from RCU, where the module itself might no longer exist. Removing the arg is the safest approach. This just codifies the use of the module_alloc/module_free pattern which ftrace and bpf use.

module_arch_freeing_init(): new hook for archs before module->module_init freed.

2015-01-20T01:08:32Z

Archs have been abusing module_free() to clean up their arch-specific allocations. Since module_free() is also (ab)used by BPF and trace code, let's keep it to simple allocations, and provide a hook called before that. This means that avr32, ia64, parisc and s390 no longer need to implement their own module_free() at all. avr32 doesn't need module_finalize() either.

tile: Use the more common pr_warn instead of pr_warning

2014-11-11T20:51:42Z

And other message logging neatening. Other miscellanea: o coalesce formats o realign arguments o standardize a couple of macros o use __func__ instead of embedding the function name Signed-off-by: Joe Perches Signed-off-by: Chris Metcalf

mm/vmalloc.c: clean up map_vm_area third argument

2014-08-07T01:01:19Z

Currently map_vm_area() takes (struct page *** pages) as third argument, and after mapping, it moves (*pages) to point to (*pages + nr_mappped_pages). It looks like this kind of increment is useless to its caller these days. The callers don't care about the increments and actually they're trying to avoid this by passing another copy to map_vm_area(). The caller can always guarantee all the pages can be mapped into vm_area as specified in first argument and the caller only cares about whether map_vm_area() fails or not. This patch cleans up the pointer movement in map_vm_area() and updates its callers accordingly.

modules: don't hand 0 to vmalloc.

2012-12-14T02:36:43Z

In commit d0a21265dfb5fa8a David Rientjes unified various archs' module_alloc implementation (including x86) and removed the graduitous shortcut for size == 0. Then, in commit de7d2b567d040e3b, Joe Perches added a warning for zero-length vmallocs, which can happen without kallsyms on modules with no init sections (eg. zlib_deflate). Fix this once and for all; the module code has to handle zero length anyway, so get it right at the caller and remove the now-gratuitous checks within the arch-specific module_alloc implementations.

arch/tile: factor out header

2011-11-03T20:58:54Z

The kernel code was using some headers that included a mix of hardware-specific information (typically found in Tilera headers) and structures, enums, and function declarations supporting the disassembly function of the tile-desc.c sources. This change refactors that code so that a hardware-specific, but OS- and application-agnostic header, is created: . This header is then exported to userspace along with the other headers and can be used to build userspace code; in particular, it is used by glibc as part of implementing the backtrace() function. The new header, together with a header that specifically describes the disassembly code ( with _32 and _64 variants), replaces the old and headers. As part of this change, we are also renaming the 32-bit constants from TILE_xxx to TILEPRO_xxx to better reflect the fact that they are specific to the TILEPro architecture, and not to TILE-Gx and any successor "tile" architecture chips.

modules: make arch's use default loader hooks

2011-07-24T12:36:04Z

This patch removes all the module loader hook implementations in the architecture specific code where the functionality is the same as that now provided by the recently added default hooks.
