Pull asm-generic uaccess.h cleanup from Arnd Bergmann: "Like in 3.19, I once more have a multi-stage cleanup for one asm-generic header file, this time the work was done by Michael Tsirkin and cleans up the uaccess.h file in asm-generic, as well as all architectures for which the respective maintainers did not pick up his patches directly" * tag 'asm-generic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: (37 commits) sparc32: nocheck uaccess coding style tweaks sparc64: nocheck uaccess coding style tweaks xtensa: macro whitespace fixes sh: macro whitespace fixes parisc: macro whitespace fixes m68k: macro whitespace fixes m32r: macro whitespace fixes frv: macro whitespace fixes cris: macro whitespace fixes avr32: macro whitespace fixes arm64: macro whitespace fixes arm: macro whitespace fixes alpha: macro whitespace fixes blackfin: macro whitespace fixes sparc64: uaccess_64 macro whitespace fixes sparc32: uaccess_32 macro whitespace fixes avr32: whitespace fix sh: fix put_user sparse errors metag: fix put_user sparse errors ia64: fix put_user sparse errors ...
OpenRISC Linux ============== This is a port of Linux to the OpenRISC class of microprocessors; the initial target architecture, specifically, is the 32-bit OpenRISC 1000 family (or1k). For information about OpenRISC processors and ongoing development: website http://openrisc.net For more information about Linux on OpenRISC, please contact South Pole AB. email: [email protected] website: http://southpole.se http://southpoleconsulting.com --------------------------------------------------------------------- Build instructions for OpenRISC toolchain and Linux =================================================== In order to build and run Linux for OpenRISC, you'll need at least a basic toolchain and, perhaps, the architectural simulator. Steps to get these bits in place are outlined here. 1) The toolchain can be obtained from openrisc.net. Instructions for building a toolchain can be found at: http://openrisc.net/toolchain-build.html 2) or1ksim (optional) or1ksim is the architectural simulator which will allow you to actually run your OpenRISC Linux kernel if you don't have an OpenRISC processor at hand. git clone git://openrisc.net/jonas/or1ksim-svn cd or1ksim ./configure --prefix=$OPENRISC_PREFIX make make install 3) Linux kernel Build the kernel as usual make ARCH=openrisc defconfig make ARCH=openrisc 4) Run in architectural simulator Grab the or1ksim platform configuration file (from the or1ksim source) and together with your freshly built vmlinux, run your kernel with the following incantation: sim -f arch/openrisc/or1ksim.cfg vmlinux --------------------------------------------------------------------- Terminology =========== In the code, the following particles are used on symbols to limit the scope to more or less specific processor implementations: openrisc: the OpenRISC class of processors or1k: the OpenRISC 1000 family of processors or1200: the OpenRISC 1200 processor --------------------------------------------------------------------- History ======== 18. 11. 2003 Matjaz Breskvar ([email protected]) initial port of linux to OpenRISC/or32 architecture. all the core stuff is implemented and seams usable. 08. 12. 2003 Matjaz Breskvar ([email protected]) complete change of TLB miss handling. rewrite of exceptions handling. fully functional sash-3.6 in default initrd. a much improved version with changes all around. 10. 04. 2004 Matjaz Breskvar ([email protected]) alot of bugfixes all over. ethernet support, functional http and telnet servers. running many standard linux apps. 26. 06. 2004 Matjaz Breskvar ([email protected]) port to 2.6.x 30. 11. 2004 Matjaz Breskvar ([email protected]) lots of bugfixes and enhancments. added opencores framebuffer driver. 09. 10. 2010 Jonas Bonn ([email protected]) major rewrite to bring up to par with upstream Linux 2.6.36
