2007-07-12Define zero-page offset 0x1e4 as a scratch field, and use itH. Peter Anvin2-6/+6
The relocatable kernel code needs a scratch field for the decompressor to determine its own location.

2007-07-12Use a new CPU feature word to cover features that are spread aroundVenki Pallipadi6-1/+69
Some Intel features are spread around in different CPUID leafs like 0x5, 0x6 and 0xA. Make this feature detection code common across i386 and x86_64. Display Intel Dynamic Acceleration feature in /proc/cpuinfo. This feature will be enabled automatically by current acpi-cpufreq driver.

2007-07-10[MIPS] PNX8550: Cleanup proc code.Robert P. J. Day1-13/+17
Here's a slightly cleaner way of creating the /proc structure for the pnx8850. mostly, it creates a directory with default mode 555, since the one you're creating is mode 444, which is somewhat unusual for a directory under /proc. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-07-10[MIPS] Add debugfs files to show fpuemu statisticsAtsushi Nemoto1-0/+34
Export contents of struct mips_fpu_emulator_stats via debugfs. There is no way to read these statistics for now but they (at least the "emulated" count) might be sometimes useful for performance tuning on FPU-less CPUs.

2007-07-10[MIPS] Add some debugfs files to debug unaligned accessesAtsushi Nemoto2-3/+54
Currently a number of unaligned instructions is counted but not used. Add /debug/mips/unaligned_instructions file to show the value. And add /debug/mips/unaligned_action to control behavior upon an unaligned access. Possible actions are: 0: silently fixup the unaligned access. 1: send SIGBUS. 2: dump registers, process name, etc. and fixup.

2007-07-10[MIPS] rbtx4938: Fix secondary PCIC and glue internal NICsAtsushi Nemoto2-63/+70
* Fix pci ops for secondary PCIC * Do not reserve 1MB for PCI MEM region (leave PCIBIOS_MIN_MEM zero) * Use platform_device to provide ethernet addresses for internal NICs. (background: TX49XX SoCs include PCI NIC (TC35815 compatible) connected via its internal PCI bus, but the NIC's PROM interface is not connected to SEEPROM. So we must provide its ethernet address by another way.) * Check return value of early_read_config_word() Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-07-10[MIPS] Make ioremap() work on TX39/49 special unmapped segmentAtsushi Nemoto1-0/+2
TX39XX and TX49XX have "reserved" segment in CKSEG3 area. 0xff000000-0xff3fffff on TX49XX and 0xff000000-0xfffeffff on TX39XX are reserved (unmapped, uncached). Controllers on these SoCs are placed in this segment. This patch add plat_ioremap() and plat_iounmap() to override default behavior and implement these hooks for TX39/TX49.
