Temporary strings with volt_* file names should be released after the
debugfs entries are created. While at it, also simplify the string
allocation, and use just snprintf() to create the name.

hpte_need_flush() might be called outside of a preempt section
when manipulating the kernel page tables, so we need to use the
appopriate variants of per-cpu variable accesses. There should
be no risk of being in the middle of a batch and a context
switch will flush any pending batch.

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.

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(®->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:
- ®->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)

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. In the worst case, this could cause
system power management to behave incorrectly.

Without CONFIG_OMAP_32K_TIMER, the kernel has an clockevent and
clocksource resolution about three orders of magnitude higher than

power consumption states are not available.

On some SB800 systems polarity for IOAPIC pin2 is wrongly
specified as low active by BIOS. This caused system hangs after
resume from S3 when HPET was used in one-shot mode on such

In OMAP35X TRM Rev 2010-05 Figure 7-18 "DPLL With EMI Reduction
Feature", it is shown that the internal frequency is calculated by
CLK_IN/(N+1). However, the value passed to _dpll_test_fint() is
already "N+1" since Linux is using the values to divide by. In the
technical reference manual, "N" is referring to the divider's register
value (0-127).
During power management testing, it was observed that programming the
wrong jitter correction value can cause the system to become unstable
and eventually crash.

We need to delay freeing any mapped page on SMP and ARMv7 systems to
ensure that the data is not accessed by other CPUs, or is used for
speculative prefetch with ARMv7. This includes not only mapped pages
but also pages used for the page tables themselves.
This avoids races with the MMU/other CPUs accessing pages after they've
been freed but before we've invalidated the TLB.
