If firmware allows us to map all of a partition's memory for DMA on a particular bridge, create a 1:1 mapping of that memory. Add hooks for dealing with hotplug events. Dynamic DMA windows can use larger than the default page size, and we use the largest one possible.

The rtas_event_scan() function uses smp_processor_id() to select a starting point in cpu_online_mask, and does so under the protection of get_online_cpus().

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.

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 systems because a timer interrupt was missed (HPET signal is high active).

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. Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>
