To unify Makefile for sparc and sparc64 a few other steps was needed: 1) separate defconfig files for sparc and sparc64 is required, so locate these in arch/sparc/configs 2) removoval of hack in toplevel Makefile to deal with that headers was in a separate directory compared to the rest The unification of the Makefile required usage of several foo-$(CONFIG_SPARCnn) += due to a few directories pending unification. This will be cleaned up when we unify the remaining directories. Included in this patch are the deletion of a few files in sparc64 as they are no longer needed: Makefile + Kconfig. arch/sparc64/ will after this patch is applied only have four directories (prom, lib, kernel, boot) Signed-off-by:Sam Ravnborg <sam@ravnborg.org> Signed-off-by:

With this 'git status' no longer reports any new files At least not for a sparc allnoconfig build Signed-off-by:

The btfixup step needs knowledge of all the .o files, but there is no need to pass them in independent variables. Simplify it to use only two variables. Signed-off-by:

sparc64 does not use constants generated from asm-offsets but to prepare it to do so the parts that could be shared do now generate constants for sparc64 too. Signed-off-by:

This patch makes the two vmlinux.lds.S files identical and serve as documentation for the changes in each file. This mainly add stuffs to sparc32 that is otherwise only used by sparc64 and thus it should have no effect. Build tested only. Signed-off-by:

This is complicated a little because compat_audit.c wants to see only the 32bit syscall numbers, but is being built in a 64bit compile. Signed-off-by:

We use clock cycle counter, adjusted to HZ. This can be extended to sun4v based processors as well, as they also have a proper overflow interrupt facility for the performance counters. Signed-off-by: -

It writes the %pic register, keeping mind of processor bugs. Implement reset_pic() in terms of it. Signed-off-by: -

In these instructions we load the new thread register, switch the register window, and setup the new frame pointer. All of these must appear atomic, and things will explode if we take a PIL=15 NMI interrupt in the middle of this sequence. Signed-off-by: -

We don't want the rtrap path to try and run softirqs or anything like that when returning from a PIL==15 NMI. Signed-off-by: -

So that we can profile code even in a local_irq_disable() section, only write 14 (instead of 15) into the %pil register to disable IRQs. This allows PIL level 15 to serve as a pseudo NMI. Signed-off-by: -

Stephen Rothwell pointed out that pcmcia can't be enabled on sparc64. There is an empty non-prompt PCMCIA explicit entry in arch/sparc/Kconfig but that doesn't do anything. 32-bit sparc needs a small hack to make this work, since it doesn't use the generic IRQ layer yes. We have to provide a dummy definition of probe_irq_mask(), since this is used by the yenta socket driver. Signed-off-by: -

Add a sysctl to tweak the RSS limit used to decide when to grow the TSB for an address space. In order to avoid expensive divides and multiplies only simply positive and negative powers of two are supported. The function computed takes the number of TSB translations that will fit at one time in the TSB of a given size, and either adds or subtracts a percentage of entries. This final value is the RSS limit. See tsb_size_to_rss_limit(). Signed-off-by: -

- move all sparc64/mm/ files to arch/sparc/mm/ - commonly named files are named _64.c - add files to sparc/mm/Makefile preserving link order - delete now unused sparc64/mm/Makefile - sparc64 now finds mm/ in sparc Signed-off-by:

A simple: diff arch/sparc64/oprofile/init.c arch/sparc/oprofile/init.c diff arch/sparc64/oprofile/Makefile arch/sparc/oprofile/Makefile revealed that the directories were equal. So let sparc64 point to the sparc version and drop the sparc64 oprofile dir Signed-off-by:

Merge all of sparc64 Kconfig to sparc Kconfig. The merge was checked by: - visual inspection in menuconfig - result of allnoconfig, allmodconfig, allyesconfig was checked before and after - result of a number of randconfig was checked before and after scripts/diffconfig was used to check if the config differed before and after The validity of the test was checked by on purpose introducing a few bugs - and they were all caught by first run.

The kernel always executes in the TSO memory model now, so none of this stuff is necessary any more. With helpful feedback from Nick Piggin. Signed-off-by: -

The fact of the matter is, all UltraSPARC-III and later chips only implement TSO. They don't implement PSO and RMO memory models at all. Only the Ultra-I and Ultra-II family chips implement RMO and they are only helped marginally by using this setting when executing kernel code. The big plus to doing this is that we can eliminate all of the non-Sync memory barriers in the kernel except for the ones used in the optimized memcpy/memset code (these use block load and store operations which have their own memory ordering rules).
