It has been part of the linux-next tree for some time. Most changes are inside the xtensa subdirectory; the other changes mostly add another rule to already existing #ifdefs to exclude Xtensa, where required. The only 'common' change is to add two more sections ('.xt.prop' and '.xt.lit') to the white list in modpost." * tag 'xtensa-next-20121008' of git://github.com/czankel/xtensa-linux: (27 commits) xtensa: Setup CROSS_COMPILE at the top xtensa: drop CONFIG_EMBEDDED_RAMDISK xtensa: fix TIOCGSERIAL and TIOCSSERIAL definitions xtensa: provide dummy gcc intrinsics xtensa: add missing symbol exports parport: disable for xtensa arch xtensa: rename MISC SR definition to avoid name clashes hisax: disable build for big-endian xtensa xtensa: fix CODA build xtensa: fix parallel make xtensa: ISS: drop unused io.c xtensa: ISS: exit simulator in case of halt or poweroff xtensa: ISS: change keyboard polling rate xtensa: ISS: add platform_pcibios_init xtensa: ISS: add dummy serial.h for ISS platform xtensa: change default platform clock frequency to 10MHz xtensa: add ARCH_WANT_OPTIONAL_GPIOLIB to xtensa config xtensa: set NO_IOPORT to 'n' by default xtensa: adopt generic io routines xtensa: fix ioremap ...
| * xtensa: Setup CROSS_COMPILE at the topGeert Uytterhoeven2012-10-04
| | | | | | | | | | | | | | | | | | | | CROSS_COMPILE must be setup before using e.g. cc-option (and a few other as-*, cc-*, ld-* macros), else they will check against the wrong compiler when cross-compiling, and may invoke the cross compiler with wrong or suboptimal compiler options.

| | | | | | | | | | | | | | | | | | | | | | | | Put equivalent constants into TIOCGSERIAL and TIOCSSERIAL definitions: size subfield of these IOCTL codes is not used and no other architecture uses _IO* macros here.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes an assumption that cclk's initial divisor will always be 1 (or 0 in the register). TSCALE is always initialized on startup with a value of 4 regardless of the inital cclk divisor; so, we can't make the assumption without making lots of other assumptions. The TPERIOD value is set with a value of the current cclk (value / (HZ * TSCALE)) - 1; so, we need to adjust based on this initial frequency and not use cclk's initial divisor for adjusting the tscale.

A fair chunk of them are platform updates to the Cavium Octeon SOC (which involves machine generated header files of considerable size), Atheros ATH79xx, RMI aka Netlogic aka Broadcom XLP, Broadcom BCM63xx platforms. Support for the commercial MIPS simulator MIPSsim has been removed as MIPS Technologies is shifting away from this product and Qemu is offering various more powerful platforms. The generic MIPS code can now also probe for no-execute / write-only TLB features implemented without the full SmartMIPS extension as permitted by the latest MIPS processor architecture. Lots of small changes to generic code." * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (78 commits) MIPS: ath79: Fix CPU/DDR frequency calculation for SRIF PLLs MIPS: ath79: use correct fractional dividers for {CPU,DDR}_PLL on AR934x MIPS: BCM63XX: Properly handle mac address octet overflow MIPS: Kconfig: Avoid build errors by hiding USE_OF from the user.
