Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[SPARC64]: Eliminate irq_cpustat_t. We can put the __softirq_pending mask in the cpudata, no need for the silly NR_CPUS array in kernel/softirq.c Signed-off-by: David S. Miller <davem@davemloft.net>

[SPARC64]: Kill pgtable quicklists and use SLAB. Taking a nod from the powerpc port. With the per-cpu caching of both the page allocator and SLAB, the pgtable quicklist scheme becomes relatively silly and primitive. Signed-off-by: David S. Miller <davem@davemloft.net>

/* Dcache line 2, rarely used */
[SPARC64]: Probe D/I/E-cache config and use. At boot time, determine the D-cache, I-cache and E-cache size and line-size. Use them in cache flushes when appropriate. This change was motivated by discovering that the D-cache on UltraSparc-IIIi and later are 64K not 32K, and the flushes done by the Cheetah error handlers were assuming a 32K size. There are still some pieces of code that are hard coding things and will need to be fixed up at some point. While we're here, fix the D-cache and I-cache parity error handlers to run with interrupts disabled, and when the trap occurs at trap level > 1 log the event via a counter displayed in /proc/cpuinfo.
