2009-12-15tree-wide: convert open calls to remove spaces to skip_spaces() lib functionAndré Goddard Rosa
Makes use of skip_spaces() defined in lib/string.c for removing leading spaces from strings all over the tree. It decreases lib.a code size by 47 bytes and reuses the function tree-wide: text data bss dec hex filename 64688 584 592 65864 10148 (TOTALS-BEFORE) 64641 584 592 65817 10119 (TOTALS-AFTER) Also, while at it, if we see (*str && isspace(*str)), we can be sure to remove the first condition (*str) as the second one (isspace(*str)) also evaluates to 0 whenever *str == 0, making it redundant. In other words, "a char equals zero is never a space". Julia Lawall tried the semantic patch (http://coccinelle.lip6.fr) below, and found occurrences of this pattern on 3 more files: drivers/leds/led-class.c drivers/leds/ledtrig-timer.c drivers/video/output.c @@ expression str; @@ ( // ignore skip_spaces cases while (*str && isspace(*str)) { \(str++;\|++str;\) } | - *str && isspace(*str) ) Signed-off-by: André Goddard Rosa <andre.goddard@gmail.com> Cc: Julia Lawall <julia@diku.dk> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Cc: Jeff Dike <jdike@addtoit.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: "H.

2009-12-15cs5535: drop the Geode-specific MFGPT/GPIO codeAndres Salomon

2009-12-15cs5535: add a generic MFGPT driverAndres Salomon
This is based on the old code on arch/x86/kernel/mfgpt_32.c, except it's not x86 specific, it's modular, and it makes use of a PCI BAR rather than a random MSR. Currently module unloading is not supported; it's uncertain whether or not it can be made work with the hardware.

2009-12-15ALSA: cs5535audio: free OLPC quirks from reliance on MGEODE_LX cpu optimizationAndres Salomon
Previously, OLPC support for the mic extensions was only enabled in the ALSA driver if CONFIG_OLPC and CONFIG_MGEODE_LX were both set. This was because the old geode GPIO code was written in a manner that assumed CONFIG_MGEODE_LX. With the new cs553x-gpio driver, this is no longer the case; as such, we can drop the requirement on CONFIG_MGEODE_LX and instead include a requirement on GPIOLIB. We use the generic GPIO API rather than the cs553x-specific API.

2009-12-15cs5535-gpio: add AMD CS5535/CS5536 GPIO driver supportAndres Salomon
This creates a CS5535/CS5536 GPIO driver which uses a gpio_chip backend (allowing GPIO users to use the generic GPIO API if desired) while also allowing architecture-specific users directly (via the cs5535_gpio_* functions). Tested on an OLPC machine. Some Leemotes also use CS5536 (with a mips cpu), which is why this is in drivers/gpio rather than arch/x86. Currently, it conflicts with older geode GPIO support; once MFGPT support is reworked to also be more generic, the older geode code will be removed.

2009-12-14x86, mce: Thermal monitoring depends on APIC being enabledCyrill Gorcunov
Add check if APIC is not disabled since thermal monitoring depends on it. As only apic gets disabled we should not try to install "thermal monitor" vector, print out that thermal monitoring is enabled and etc... Note that "Intel Correct Machine Check Interrupts" already has such a check. Also I decided to not add cpu_has_apic check into mcheck_intel_therm_init since even if it'll call apic_read on disabled apic -- it's safe here and allow us to save a few code bytes.

They can allocate aperture by hand and use GART. - GART systems without GAP must disable GART on shutdown. - swiotlb usage is forced by the boot option, gart_iommu_hole_init() is not called, so we disable GART early_gart_iommu_check().

2009-12-14microblaze: Enable asm optimization only for HW with barrel-shifterMichal Simek
Asm code uses barrel-shifter instruction that's why we have to protect cases when HW don't have it. Reported-by: John Linn <john.linn@xilinx.com> Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-12-14microblaze: Remove the buggy ALLOW_EDIT_AUTO config optionJohn Williams
This was intended to allow manual override of CPU settings copied automatically to Kconfig.auto, however it's problematic for several reasons, but mostly: * If the defconfig doesn't have ALLOW_EDIT_AUTO=y, then it's impossible for that defconfig to iverride the values in the kernel source tree. This leads to very strange errors where the kernel is compiled with the wrong CPUFLAGS. Next patch in the series will back out the default in Kconfig.auto to baseline settings, so a kernel built with no default values will at least boot on any hardware, just not make use of additional CPU features.

2009-12-14microblaze: support U-BOOT image formatMichal Simek
Two version are generated. linux.bin.ub which is created from linux.bin file and simpleImage.<dts>.ub which is created from stripped simpleImage.<dts> file Load address and entry point is for microblaze first instruction which is CONFIG_KERNEL_BASE_ADDR variable. There is possible for simpleImage format parse _start symbol too. simpleImage.<dts> is still stripped elf file I cleared simpleImage.<dts>.unstrip file because there are so big.

2009-12-14microblaze: Ptrace notifying from signal codeMichal Simek
After the signal frame is set up on the userspace stack, ptrace() should be given an opportunity to single-step into the signal handler FRV, Blackfin, mn10300 and UM. Worth to look at that patches. Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-12-14microblaze: Extend cpuinfo for support write-back cachesMichal Simek
There is missing checking agains PVR but this is not important for now. There are some missing checking too. Signed-off-by: Michal Simek <monstr@monstr.eu>
