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>

/* * CPUs often take a performance hit when accessing unaligned memory * locations. 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.

Simplify "make ARCH=x86" and fix kconfig so we again can set 64BIT in all.config. For a fix the diffstat is nice: 6 files changed, 3 insertions(+), 36 deletions(-) The patch reverts these commits: - 0f855aa6 ("kconfig: add helper to set config symbol from environment variable") - 2a113281 ("kconfig: use $K64BIT to set 64BIT with all*config targets") Roman Zippel pointed out that kconfig supported string compares so the additional complexity introduced by the above two patches were not needed. With this patch we have following behaviour: # make {allno,allyes,allmod,rand}config [ARCH=...] option \ host arch | 32bit | 64bit ===================================================== ./. | 32bit | 64bit ARCH=x86 | 32bit | 32bit ARCH=i386 | 32bit | 32bit ARCH=x86_64 | 64bit | 64bit The general rule are that ARCH= and native architecture takes precedence over the configuration. So make ARCH=i386 [whatever] will always build a 32-bit kernel no matter what the configuration says. The configuration will be updated to 32-bit if it was configured to 64-bit and the other way around. This behaviour is consistent with previous behaviour so no suprises here. make ARCH=x86 will per default result in a 32-bit kernel but as the only ARCH= value x86 allow the user to select between 32-bit and 64-bit using menuconfig.
