Here is update of ufs cleanup patch, brought on by the recently fixed ubh_get_usb_second() bug that made some ugly code rather painfully obvious. It also includes - fix compilation warnings which appears if debug mode turn on - remove unnecessary duplication of code to support UFS2 I tested it on ufs1 and ufs2 file-systems.

The Cherry Cymotion is a special Linux keyboard made by Cherry, with only one little problem: it doesn't work with Linux.

The first generation of PCI powermacs had a host bridge called /chaos which was for all intents and purposes a PCI host bridge, but has a device_type of "vci" in the device tree (presumably it's not really PCI at the hardware level or something). The OF parsing stuff in arch/powerpc/kernel/prom_parse.c currently doesn't recognize it as a PCI bridge, which means that controlfb.c can't get its device addresses. This makes prom_parse.c recognize a device_type of "vci" as indicating a PCI host bridge. With this, controlfb works again.

The 601 processor will generate an alignment exception for accesses which cross a page boundary. In the boot wrapper code, OF is still handling all exceptions, and it doesn't have an alignment exception handler that emulates the instruction and continues. This changes the memcpy and memmove routines in the boot wrapper to avoid doing unaligned accesses. If the source and destination are misaligned with respect to each other, we just copy one byte at a time. Signed-off-by: Paul Mackerras <paulus@samba.org>

Handle the ibm,suspend-me RTAS call specially. It needs to be wrapped in a set of synchronization hypervisor calls (H_Join). When the H_Join calls are made on all CPUs, the intent is that only one will return with H_Continue, meaning that he is the "last man standing". That CPU then issues the ibm,suspend-me call. What is interesting, of course, is that the CPU running when the rtas syscall is made, may NOT be the CPU that ultimately executes the ibm,suspend-me rtas call.

The arch/powerpc version of process.c exports get_wchan itself. When I moved ARCH=ppc over to using arch/powerpc/kernel/process.c the get_wchan export in arch/ppc/kernel/ppc_ksyms.c became redundant, so remove it.

The following implements support for instantiation of 8MB D-TLB entries for the kernel direct virtual mapping on 8xx, thus reducing TLB space consumed for the kernel. Test used: writing 40MB from /dev/zero to file in ext2fs over RAMDISK. $ time dd if=/dev/zero of=file bs=4k count=10000 VANILLA 8MB kernel data pages real 0m11.485s real 0m11.267s user 0m0.218s user 0m0.250s sys 0m8.939s sys 0m9.108s real 0m11.518s real 0m10.978s user 0m0.203s user 0m0.222s sys 0m9.585s sys 0m9.138s real 0m11.554s real 0m10.967s user 0m0.228s user 0m0.222s sys 0m9.497s sys 0m9.127s real 0m11.633s real 0m11.286s user 0m0.214s user 0m0.196s sys 0m9.529s sys 0m9.134s and averages for both: real 11.54750 real 11.12450 Which is a 3.6% improvement in execution time.

Parse the flat device tree for devices on Freescale SOC's that we know about (gianfar, gianfar_mdio, i2c, mpc83xx_wdt). We need to setup platform devices and platform data for these devices to match arch/ppc usage. Also add a helper function (get_immrbase) that reports the base address of the MMIO registers on the SOC.

In 2.6.15-git6 a change was commited in the oprofile support in the powerpc architecture. It introduced the powerpc_oprofile_type which contains the define G4. This causes a name clash with the existing wacom usb tablet driver. CC [M] drivers/usb/input/wacom.o drivers/usb/input/wacom.c:98: error: conflicting types for `G4' include/asm/cputable.h:37: error: previous declaration of `G4' CC [M] drivers/usb/mon/mon_text.o make[3]: *** [drivers/usb/input/wacom.o] Error 1 make[2]: *** [drivers/usb/input] Error 2 The elements of an enum declared in global scope are effectivly global identifiers themselves. As such we need to ensure the names are unique. This patch updates the later oprofile support to use unique names.

The glibc folks want to use AT_PLATFORM to select between possible alternative versions of shared libraries. This commit makes the kernel supply an AT_PLATFORM string that indicates what class of processor we are running on. Processors with the same set of user-level instructions and roughly the same instruction scheduling characteristics are given the same AT_PLATFORM value; for example, 821, 823 and 860 are all reported as "ppc823", and 7447, 7447A, 7448, 7450, 7451, 7455 are all called "ppc7450". The intention is that the AT_PLATFORM values match the values that gcc accepts for the -mcpu= option. For values which are numeric (e.g. -mcpu=750), "ppc" has been prepended. This also adds a PPC_FEATURE_BOOKE bit to the AT_HWCAP value and sets it for the 440 family and the Freescale 85xx family. Signed-off-by: Paul Mackerras <paulus@samba.org>

Add hotplug cpu support to salinfo.c. The cpu_event field is a cpumask so use the cpu_* macros consistently, replacing the existing mixture of cpu_* and *_bit macros. Instead of counting the number of outstanding events in a semaphore and trying to track that count over user space context, interrupt context, non-maskable interrupt context and cpu hotplug, replace the semaphore with a test for "any bits set" combined with a mutex. Modify the locking to make the test for "work to do" an atomic operation. Signed-off-by: Keith Owens <kaos@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
