2011-03-01[CPUFREQ] Missing "unregister_cpu_notifier" in powernow-k8.cNeil Brown
It appears that when powernow-k8 finds that No compatible ACPI _PSS objects found. and suggests Try again with latest BIOS. it fails the module load, but does not unregister the cpu_notifier that was registered in powernowk8_init This ends up leaving freed memory on the cpu notifier list for some other poor module (e.g. md/raid5) to come along and trip over. The following might be a partial fix, but I suspect there is probably other clean-up that is needed. ( https://bugzilla.novell.com/show_bug.cgi?id=655215 has full dmesg traces).

2011-02-28davinci: tnetv107x: fix register indexing for GPIOs numbers > 31Hirosh Dabui
This patch fix a bug in the register indexing for GPIOs numbers > 31 to get the relevant hardware registers of tnetv107x to control the GPIOs. In the structure tnetv107x_gpio_regs: struct tnetv107x_gpio_regs { u32 idver; u32 data_in[3]; u32 data_out[3]; u32 direction[3]; u32 enable[3]; }; The GPIO hardware register addresses of tnetv107x are stored. The chip implements 3 registers of each entity to serve 96 GPIOs, each register provides a subset of 32 GPIOs. The driver provides these macros: gpio_reg_set_bit, gpio_reg_get_bit and gpio_reg_clear_bit. The bug implied the use of macros to access the relevant hardware register e.g. the driver code used the macro like this: 'gpio_reg_clear_bit(&reg->data_out, gpio)' But it has to be used like this: 'gpio_reg_clear_bit(reg->data_out, gpio)'. The different results are shown here: - &reg->data_out + 1 (it will add the full array size of data_out i.e. 12 bytes) - reg->data_out + 1 (it will increment only the size of data_out i.e. only 4 bytes) Acked-by: Cyril Chemparathy <cyril@ti.com> Signed-off-by: Hirosh Dabui <hirosh.dabui@snom.com> Signed-off-by: Kevin Hilman <khilman@ti.com>

2011-02-28x86: Use u32 instead of long to set reset vector back to 0Don Zickus
A customer of ours, complained that when setting the reset vector back to 0, it trashed other data and hung their box. They noticed when only 4 bytes were set to 0 instead of 8, everything worked correctly. Mathew pointed out: | | We're supposed to be resetting trampoline_phys_low and | trampoline_phys_high here, which are two 16-bit values. | Writing 64 bits is definitely going to overwrite space | that we're not supposed to be touching. | So limit the area modified to u32.

CPU0 and CPU1 clockdomain is at the offset of 0x18 from the LPRM base. The header file has set it wrongly to 0x0. Offset 0x0 is for CPUx power domain control register Fix the same. The autogen scripts is fixed thanks to Benoit Cousson With the old value, the clockdomain code would access the *_PWRSTCTRL.POWERSTATE field when it thought it was accessing the *_CLKSTCTRL.CLKTRCTRL field.
