2008-12-26sparc64: use bit neutral Elf symbolsSam Ravnborg
To prepare for unification use the bit neutral versions of the Elf types defined by asm/module.h Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-26sparc: unify module.hSam Ravnborg
Use some preprocessor magic in combination with the newly introduced CONFIG_BITS to unify module.h. A few additional symbols are added as they are needed in a follow-up patch Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-26sparc: introduce CONFIG_BITSSam Ravnborg
CONFIG_BITS is set to 32 for sparc32 and 64 for sparc64. This allow us to use this symbol in for example header files to ease unification of sparc32 and sparc64. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-26sparc: fix hardirq.h removal falloutSam Ravnborg
When hardirq.h are removed from asm-generic/local.h a few bits fails to build. Fix these upfront. Reported by Alexey Dobriyan. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-11sparc64: do not export pus_fs_structSam Ravnborg
Al asked: BTW, why does sparc64 export put_fs_struct? Grepping the kernel tree did not show any users of an exported put_fs_struct - so drop the export. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-11sparc: use sparc64 version of scatterlist.hRobert Reif
Use sparc64 version of scatterlist.h. There are three main differences: dma_addr_t replaces __u32 dma_address replaces dvma_address dma_length replaces dvma_length dma_addr_t is a u32 on sparc32. Boot tested on sparc32. Signed-off-by: Robert Reif <reif@earthlink.net> Signed-off-by: David S. Miller <davem@davemloft.net>

Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-09sparc: Unify strlen assembler.David S. Miller
Use the new asm/asm.h header to help commonize the strlen assembler between 32-bit and 64-bit While we're here, use proper linux/linkage.h macros instead of by-hand stuff. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-09sparc: Add asm/asm.hDavid S. Miller
This will contain macros that help share assembler code between the 32-bit and 64-bit platform. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-12-08sparc: fix sparse warnings in irq_32.cSam Ravnborg
Fix following sparse warnings: symbol 'static_irqaction' was not declared. Should it be static? symbol 'static_irq_count' was not declared. Should it be static? symbol 'irq_action_lock' was not declared. Should it be static? symbol 'unexpected_irq' was not declared. Should it be static? symbol 'handler_irq' was not declared. Should it be static? returning void-valued expression returning void-valued expression returning void-valued expression symbol 'init_IRQ' was not declared. Should it be static? Warnings were fixed by addding proper declarations and fixing return path of a few functions. There remains several warnings all related to the floppy driver. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-08sparc: add include guards to kernel.hSam Ravnborg

2008-12-08sparc: Use sparc64 version of prom/printf.cRobert Reif
Use sparc64 version of prom/printf.c. The only differences for sparc32 is that prom_printf is no longer exported for modules which should be OK. Signed-off-by: Robert Reif <reif@earthlink.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-08cyber2000fb: Kill the one modular sparc prom_printf call.David S. Miller

2008-12-07sparc: Restore irq_trans_init() call in prom_create_node().David S. Miller
This broke sparc64 in various ways. Add an empty dummy hook in sparc32's prom_32.c so that we can potentially handle things on that side similarly, and in particular avoid a prom_common.c ifdef :-) Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-07sparc: unify kernel/cpuSam Ravnborg
o use cpu_32.c as base o move all sparc64 definitions to the common cpu.c o use ifdef for the parts that differs and use cpu_32 as base o spitfire.h required a CONFIG_SPARC64 guard to fix build on 32 bit Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-07sparc: expand cpu tableSam Ravnborg
Prepare cputable to include sparc64 versions Declare it __initconst so it can be dropped after init Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-07sparc: fix sparse warnings in cpu_*.cSam Ravnborg
o declare variables from cpu_*.c o declare function from cpu_32.c To do this introduce a new header "kernel.h" which is local to kernel/ Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-05sparc: Always set AUDIT_ARCH, not just on sparc64.David S. Miller
Without fancy makefile rules it's not straightforward to prevent both arch/sparc/kernel/audit.o and lib/audit.o from both being used on sparc32. Since arch/sparc/kernel/audit.c is identical to lib/audit.c except some CONFIG_COMPAT protected sections of code, just use it on sparc32 too as that's the simplest way to fix this. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-05sparc: report "Unknown CPU/FPU" for unknown cpu/fpuSam Ravnborg
If we cannot determine the CPU or FPU report "Unknown CPU" or "Unknown FPU" like sparc64 does. And report with KERN_ERR that we cannot determine the CPU. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-05sparc: beautify kernel/cpu_32.cSam Ravnborg
Fixed style issues Use C99 struct assignments Use KERN_DEBUG for printk Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-05sparc: Move of_console_{device,path,options} info prom_common.cDavid S. Miller
Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-05sparc: Move prom_build_devicetree() into prom_common.cDavid S. Miller
To make this work we provide a dummy nop implementation of of_fill_in_cpu_data() for sparc32. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-05sparc: Move core of OF device tree building code into prom_common.cDavid S. Miller
Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-05sparc: Match sparc32's build_tree() up to sparc64'sDavid S. Miller
Sparc64 uses a non-recursive sibling traversal algorithm that never got propagated into the sparc32 copy of this code. Sync them up. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-05sparc: Move create_node() and friends into prom_common.cDavid S. Miller
Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-05sparc: Make sparc32's create_node() assign parent pointer.David S. Miller
This makes it match what sparc64's version does. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-05sparc: Commonize get_one_property() implementations.David S. Miller
Add final len assignment in sparc64's get_one_property() (it's necessary to avoid unchecked return value warnings on the sparc32 side), and mark name argument const on sparc32's copy. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-05sparc: Move property building code into prom_common.cDavid S. Miller
Unfortunately there is some sparc32/sparc64 ifdef'ery in here due to the difference in how the prom_firstprop() and prom_nextprop() routines work. This will be eliminated eventually. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-05sparc: Move 'unique_id' into prom_common.c and rename to 'prom_unique_id'David S. Miller
This will be used in a subsequent changeset. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-05sparc: Move irq_trans_init() and support code into seperate file.David S. Miller
All sparc64 specific, so only build this file on sparc64. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-05sparc: Mark prom_early_alloc non-static.David S. Miller
A subsequent changeset will use this. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-05sparc: Create common area for OF device layer code.David S. Miller
This is where common code implementations will go as we unify 32-bit and 64-bit OF device tree code. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-05sparc: Const'ify prom_*prop*() on sparc32.David S. Miller
This brings things in line with sparc64. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-05sparc: Create common header file for prom_{32,64}.cDavid S. Miller
This is where common declarations will go as we unify these files as much as possible into common code. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-04sparc: unify kernel/init_taskSam Ravnborg
A closer inspection revealed that these two files had identical functionality - but the implementation of it differed slightly. Base it on the sparc version as it was the best. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-04sparc: drop CONFIG_SUN_AUXIOSam Ravnborg
It is always equals y so no need to test for it Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-04sparc: Add missing of_node_putNicolas Palix
of_node_put is needed before discarding a value received from of_find_node_by_name, eg in error handling code or when the device node is no longer used. The semantic match that catches the bug is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r exists@ local idexpression struct device_node *n; position p1, p2; struct device_node *n1; statement S; identifier f; expression E; expression *ptr != NULL; @@ n@p1 = of_find_node_by_name(...) ... if (!n) S ... when != of_node_put(n) when != n1 = f(n,...) when != E = n when any when strict ( return \(0\|<+...n...+>\|ptr\); | return@p2 ...; | of_node_put(n); | n1 = f(n,...) | E = n ) @script:python@ p1 << r.p1; p2 << r.p2; @@ print "* file: %s of_find_node_by_name %s return %s" % (p1[0].file,p1[0].line,p2[0].line) // </smpl> Signed-off-by: Nicolas Palix <npalix@diku.dk> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S.

2008-12-04sparc,sparc64: unify boot/Sam Ravnborg
Simple unification: o renamed piggyback to *_32.c/*_64.c o copied content of Makefile from sparc64 to sparc and guard it o updated sparc/boot/.gitignore o deleted remaining files in sparc64/boot Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-04sparc,sparc64: unify kernel/Sam Ravnborg
o Move all files from sparc64/kernel/ to sparc/kernel - rename as appropriate o Update sparc/Makefile to the changes o Update sparc/kernel/Makefile to include the sparc64 files NOTE: This commit changes link order on sparc64! Link order had to change for either of sparc32 and sparc64. And assuming sparc64 see more testing than sparc32 change link order on sparc64 where issues will be caught faster.

2008-12-04sparc: prepare kernel/ for unificationSam Ravnborg
o sparc32 files with identical names to sparc64 renamed to <name>_32.S o introduced a few Kconfig helpers to simplify Makefile logic o refactored Makefile to prepare for unification - use obj-$(CONFIG_SPARC32) for sparc32 specific files - use <name>_$(BITS) for files where sparc64 has a _64 variant - sparc64 directly include a few files where sparc32 builds them, refer to these files directly (no BITS) - sneaked in -Werror as used by sparc64 o modified sparc/Makefile to use the new names for head/init_task Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-04sparc,sparc64: unify lib/Sam Ravnborg
o Renamed files in sparc64 to <name>_64.S when identical to sparc32 files. o iomap.c were equal for sparc32 and sparc64 o adjusted sparc/Makefile now we have only one lib/ Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-04sparc: prepare lib/ for unificationSam Ravnborg
Identical named files renamed to <name>_32.S Refactored Makefile to prepare for unification. Linking order was altered slightly - but this is a lib.a file so it should not matter. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-04sparc,sparc64: unify prom/Sam Ravnborg
- all files with identical names copied and renamed to *_64.c - the remaning files copied as is - added sparc64 specific files to sparc/prom/Makefile - teach sparc64 Makefile to look into sparc/prom/ - delete unused Makefile from sparc64/prom/ linking order was not kept for sparc64 with this change. It was not possible to keep linking order for both sparc and sparc64 and as sparc64 see more testing than sparc it was natural to break linking order on sparc64. Should it have any effect it would be detected sooner this way. printf_32.c and printf_64.c are obvious candidates to be merged but they are not 100% equal so that was left for later Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S.
