* SLUB: Allow full duplication of kmalloc array for 390Christoph Lameter2010-05-30
| | | | | | | | | | | | Commit 756dee75872a2a764b478e18076360b8a4ec9045 ("SLUB: Get rid of dynamic DMA kmalloc cache allocation") makes S390 run out of kmalloc caches. Increase the number of kmalloc caches to a safe size.

* slub: move kmem_cache_node into it's own cachelineAlexander Duyck2010-05-24
| | | | | | | | | | | | | | | | | | | | This patch is meant to improve the performance of SLUB by moving the local kmem_cache_node lock into it's own cacheline separate from kmem_cache. This is accomplished by simply removing the local_node when NUMA is enabled. On my system with 2 nodes I saw around a 5% performance increase w/ hackbench times dropping from 6.2 seconds to 5.9 seconds on average. I suspect the performance gain would increase as the number of nodes increases, but I do not have the data to currently back that up.

| * cmd640: fix kernel oops in test_irq() methodSergei Shtylyov2010-05-11
| | | | | | | | | | | | | | | | | | When implementing the test_iqr() method, I forgot that this driver is not an ordinary PCI driver and also needs to support VLB variant of the chip. Moreover, 'hwif->dev' should be NULL, potentially causing oops in pci_read_config_byte(). Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | The driver takes into account not only the interrupt status bit but also "FIFO empty" bit in its test_irq() method. This actually is a superfluous check since for the DMA commands calling the dma_test_irq() method further in the interrupt handler makes sure FIFO is emptied.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a little strncpy optimization which can easily cut boot time by 20%. When the kernel is booting with initramfs, it builds up the filesystem from a cpio archive by calling strncpy_from_user() via fs/namei.c's do_getname() on every file in the archive (which can be lots) with a length of PATH_MAX (1024). This causes the dest of the strncpy to be padded with many NUL bytes. This optimization mostly causes these NUL bytes to be padded with a call to memset() which is already optimized for filling memory quickly, but the hardware loop helps a little bit as well. Boot time measured with 'loglevel=0' so UART speed doesn't get in the way. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since 'extern inline' doesn't work correctly in the context of the Linux kernel (too many overriding defines), move the string functions to normal lib/ assembly files (like the existing mem funcs). This avoids the forced inline all over the kernel and allows us to place them constantly in L1. This also avoids some module failures when gcc inserts calls to string functions but the kernel build system doesn't fully consult the library archives.
