"ARCH" can be just about anything, so we shouldn't end up with UTS_MACHINE of "sparc" in a 64-bit kernel build just because someone set the personality using 'sparc32' or similar. CONFIG_SPARC64 drives the compilation and therefore provides the definitive value, not "ARCH". This mirrors commit 8c6531f7 (x86: correctly set UTS_MACHINE for "make ARCH=x86") Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This was the cause of various boot failures on V480, V880, etc. systems. Kernel image memory was being overwritten because the vmemmap[] array was being sized to small. So if you had physical memory addresses past a certain point, the early bootup would spam all over variables in the kernel data section. The vmemmap mappings map page structs, not page struct pointers. And that was the key thinko in the macro definition. This was fixable thanks to the help, reports, and tireless patience of Hermann Lauer. Reported-by: NHermann Lauer <Hermann.Lauer@iwr.uni-heidelberg.de> Signed-off-by: NDavid S.

commit ab772027 (sparc: arch/sparc/kernel/apc.c to unlocked_ioctl) added lock/unlock_kernel() to the apc ioctl code. The code needs no serialization at all. Neither put/get_user nor the read/write access to the sbus devices require it. Remove BKL. cycle_kernel_lock() was added during the big BKL pushdown. It should ensure the serializiation against driver init code. In this case there is nothing to serialize. Remove it as well.

In preparation to prune things out of the Sparc, PowerPC and Microblaze asm/prom.h files, change the #include statements to ensure that even if asm/prom.h is included first, linux/of.h gets to determine the order in which files are processed. This patch adds a #include <linux/of.h> to each of the prom.h files *above* the multi-include protection macros to ensure that linux/of.h can define things before prom.h gets processed. At the end of the merge the cross dependencies between the files should be gone and a sane #include scheme can be restored.

Thanks to tip form ARM folks and Russell King. If flush_dcache_page() occurs on a swapin it will have a mapping and we'll try to defer the flush by setting the dirty bit. But when it hits update_dcache_page() we won't flush because the page won't have a mapping any more. So remove the mapping requirement in flush_dcache(). Signed-off-by: NDavid S.

由 Peter Zijlstra 提交于
Some architectures such as Sparc, ARM and MIPS (basically everything with flush_dcache_page()) need to deal with dcache aliases by carefully placing pages in both kernel and user maps. These architectures typically have to use vmalloc_user() for this. However, on other architectures, vmalloc() is not needed and has the downsides of being more restricted and slower than regular allocations.

The hardware counter ->event_base state records and encoding of the "struct perf_event_map" entry used for the event. We use this to make sure that when we have more than 1 event, both can be scheduled into the hardware at the same time. As usual, structure of code is largely cribbed from powerpc.

Implement page mapping percpu first chunk allocator as a fallback to the embedding allocator. The next patch will make the embedding allocator check distances between units to determine whether it fits within the vmalloc area so that this fallback can be used on such cases. sparc64 currently has relatively small vmalloc area which makes it impossible to create any dynamic chunks on certain configurations leading to percpu allocation failures. This and the next patch should allow those configurations to keep working until proper solution is found. While at it, mark pcpu_cpu_distance() with __init.
