2009-12-16ptrace: x86: change syscall_trace_leave() to rely on tracehook when steppingOleg Nesterov
Suggested by Roland. Unlike powepc, x86 always calls tracehook_report_syscall_exit(step) with step = 0, and sends the trap by hand. This results in unnecessary SIGTRAP when PTRACE_SINGLESTEP follows the syscall-exit stop. Change syscall_trace_leave() to pass the correct "step" argument to tracehook and remove the send_sigtrap() logic.

2009-12-16ptrace: x86: implement user_single_step_siginfo()Oleg Nesterov
Suggested by Roland. Implement user_single_step_siginfo() for x86. Extract this code from send_sigtrap(). Since x86 calls tracehook_report_syscall_exit(step => 0) the new helper is not used yet.

2009-12-15atmel-mci: change use of dma slave interfaceNicolas Ferre
Allow the use of another DMA controller driver in atmel-mci sd/mmc driver. This adds a generic dma_slave pointer to the mci platform structure where we can store DMA controller information. In atmel-mci we use information provided by this structure to initialize the driver (with new helper functions that are architecture dependant). This also adds at32/avr32 chip modifications to cope with this new access method.

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".

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.

I tried to distangle the uncountable macro onion layers, but failed miserably. Last resort solution: switch the t2_hae_lock to raw_spinlock_t so the lock functions are pure macros and function calls again.

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.

2009-12-14x86: Gart: fix breakage due to IOMMU initialization cleanupYinghai Lu
This fixes the following breakage of the commit 75f1cdf1dda92cae037ec848ae63690d91913eac: - GART systems that don't AGP with broken BIOS and more than 4GB memory are forced to use swiotlb. 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().

2009-12-14x86: Move swiotlb initialization before dma32_free_bootmemFUJITA Tomonori
The commit 75f1cdf1dda92cae037ec848ae63690d91913eac introduced a bug that we initialize SWIOTLB right after dma32_free_bootmem so we wrongly steal memory area allocated for GART with broken BIOS earlier. This moves swiotlb initialization before dma32_free_bootmem().
