| * | Blackfin arch: fix bug kernel not to boot up with mtd filesystemsBernd Schmidt2007-11-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Revert this patch: move the init sections to the end of memory, so that after they are free, run time memory is all continugous - this should help decrease memory fragementation. When doing this, we also pack some of the other sections a little closer together, to make sure we don't waste memory. To make this happen, we need to rename the .data.init_task section to .init_task.data, so it doesn't get picked up by the linker script glob. Since it causes the kernel not to boot up with mtd filesystems. Signed-off-by: Bernd Schmidt <bernd.schmidt@analog.com> Signed-off-by: Bryan Wu <bryan.wu@analog.com>

The actual performance hit varies, it can be small if the * hardware handles it or large if we have to take an exception and fix * it * in software. * * Since an ethernet header is 14 bytes network drivers often end up * with * the IP header at an unaligned offset. The IP header can be aligned by * shifting the start of the packet by 2 bytes. Drivers should do this * with: * * skb_reserve(NET_IP_ALIGN); * * The downside to this alignment of the IP header is that the DMA is * now * unaligned. On some architectures the cost of an unaligned DMA is high * and this cost outweighs the gains made by aligning the IP header. * * Since this trade off varies between architectures, we allow * NET_IP_ALIGN * to be overridden. */ This new function insl_16 allows to read form 32-bit IO and writes to 16-bit aligned memory. This is useful in above described scenario - In particular with the AXIS AX88180 Gigabit Ethernet MAC. Once the device is in 32-bit mode, reads from the RX FIFO always decrements 4bytes. While on the other side the destination address in SDRAM is always 16-bit aligned. If we use skb_reserve(0) the receive buffer is 32-bit aligned but later we hit a unaligned exception in the IP code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes CF support for R2D-1 boards. Both R2D-1 and R2D-PLUS are equipped with CF IRQs, but the R2D-1 FPGA version seem to deliver IRQ spikes with certain CF cards during libata probing. This patch enables polling for R2D-1 as a workaround for this broken FGPA logic. R2D-1 CF support was recently introduced by commit: 43f4b8c7578b928892b6f01d374346ae14e5eb70.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the refactored update_mmu_cache() introduced in older kernels, there's no longer any need to take the page_table_lock in this path, so simply drop it completely. Without this, performance degradation is seen on SMP on heavily threaded workloads that don't use the split ptlock, and ultimately we have no reason to contend for the lock in the first place.

| |/ | | | | | | | | | | | | | | | | | | | | The __do_page_fault() fast-path contains a UTLB flush in order to force an ITLB reload, this isn't needed in practice as the ITLB is auto-reloaded from the UTLB anyways, which is already displaced by the manual 'ldtlb' in the update_mmu_cache() path. This provides a measurable speed up in the TLB miss fast-path. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
