microblaze: Fix build with make 3.82

2010-12-09T21:26:34+00:00

commit b843e4ec01991a386a9e0e9030703524446e03da upstream.

When running make headers_install_all on x86_64 and make 3.82 I hit this:

arch/microblaze/Makefile:80: *** mixed implicit and normal rules.  Stop.
make: *** [headers_install_all] Error 2

So split the rules to satisfy make 3.82.

microblaze: Disable heartbeat/enable emaclite in defconfigs

I need to disable heartbeat function because this features
breaks testing in Qemu.

microblaze: Support simpleImage.dts make target

2009-09-24T08:28:22+00:00

Instead of remembering to specify DTB= on the make commandline, this commit
allows the much friendlier make simpleImage.
where .dts is expected to be found in arch/microblaze/boot/dts/
The resulting vmlinux, with the compiled DTS linked in, will be copied to
boot/simpleImage.

This mirrors the same functionality as on PowerPC,
albeit achieving it in a slightly different way.

+ strip simpleImage file
The size of output file is very similar to linux.bin.

vmlinux - full elf without fdt blob
simpleImage..unstrip - full elf with fdt blob
simpleImage. - stripped elf with fdt blob

Add symlink to generic system.dts in platform folder

headers: utsname.h redux

2009-09-24T01:13:10+00:00

* remove asm/atomic.h inclusion from linux/utsname.h --
   not needed after kref conversion
 * remove linux/utsname.h inclusion from files which do not need it

NOTE: it looks like fs/binfmt_elf.c do not need utsname.h, however
due to some personality stuff it _is_ needed -- cowardly leave ELF-related
headers and files alone.

arches: drop superfluous casts in nr_free_pages() callers

2009-09-22T14:17:34+00:00

Commit 96177299416dbccb73b54e6b344260154a445375 ("Drop free_pages()")
modified nr_free_pages() to return 'unsigned long' instead of 'unsigned
int'.  This made the casts to 'unsigned long' in most callers superfluous,
so remove them.
