m68k: use ColdFire MMU read/write bit flags when ioremapping

2011-12-30T00:20:37+00:00

The ColdFire MMU has separate read and write bits, unlike the Motorola m68k MMU which has a single read-only bit. Define a _PAGE_READWRITE value for the Motorola MMU, which is 0, so we can unconditionaly include that in the page table entry bits when setting up ioremapped pages.

m68k: mv kmap_mm.c to kmap.c

2011-05-24T00:03:50+00:00

The non-mmu kmap_no.c has been removed. So we can move kmap_mm.c back to being the only kmap.c. Signed-off-by: Greg Ungerer

m68k: merge m68k and m68knommu arch directories

2011-03-25T04:05:13+00:00

There is a lot of common code that could be shared between the m68k and m68knommu arch branches. It makes sense to merge the two branches into a single directory structure so that we can more easily share that common code. This is a brute force merge, based on a script from Stephen King , which was originally written by Arnd Bergmann . > The script was inspired by the script Sam Ravnborg used to merge the > includes from m68knommu. For those files common to both arches but > differing in content, the m68k version of the file is renamed to > _mm. and the m68knommu version of the file is moved into the > corresponding m68k directory and renamed _no. and a small > wrapper file . is used to select between the two version. Files > that are common to both but don't differ are removed from the m68knommu > tree and files and directories that are unique to the m68knommu tree are > moved to the m68k tree. Finally, the arch/m68knommu tree is removed. > > To select between the the versions of the files, the wrapper uses > > #ifdef CONFIG_MMU > #include _mm. > #else > #include _no. > #endif On top of this file merge I have done a simplistic merge of m68k and m68knommu Kconfig, which primarily attempts to keep existing options and menus in place. Other than a handful of options being moved it produces identical .config outputs on m68k and m68knommu targets I tested it on. With this in place there is now quite a bit of scope for merge cleanups in future patches. Signed-off-by: Greg Ungerer

m68k{,nommu}/h8300: Remove obsolete comment about map_chunk

m68k: Allow ioremapping top of memory

2010-02-27T17:27:13+00:00

The test in __ioremap to reject memory ranges crossing the 0 boundary rejects also memory ranges ending at the end of the memory. Fix that. Signed-off-by: Philippe De Muyter Signed-off-by: Geert Uytterhoeven

arch/m68k/mm/kmap.c: introduce missing kfree

2008-10-14T17:23:27+00:00

Error handling code following a kmalloc should free the allocated data. The semantic match that finds the problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // @r exists@ local idexpression x; statement S; expression E; identifier f,l; position p1,p2; expression *ptr != NULL; @@ ( if ((x@p1 = $kmalloc\|kzalloc\|kcalloc$(...)) == NULL) S | x@p1 = $kmalloc\|kzalloc\|kcalloc$(...); .. if (x == NULL) S ) <... when != x when != if (...) { <+...x...+> } x->f = E ..> ( return $0\|<+...x...+>\|ptr$; | return@p2 ...; ) @script:python@ p1 << r.p1; p2 << r.p2; @@ print "* file: %s kmalloc %s return %s" % (p1[0].file,p1[0].line,p2[0].line) // Signed-off-by: Julia Lawall Signed-off-by: Geert Uytterhoeven Signed-off-by: Linus Torvalds

[PATCH] getting rid of all casts of k[cmz]alloc() calls

2006-12-13T17:05:58+00:00

Run this: #!/bin/sh for f in $(grep -Erl "$[^$]*\) *k[cmz]alloc" *) ; do echo "De-casting $f..." perl -pi -e "s/ ?= ?$[^$]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f done And then go through and reinstate those cases where code is casting pointers to non-pointers. And then drop a few hunks which conflicted with outstanding work.
