This patch populates the L1 entries for MT_MEMORY and MT_MEMORY_NONCACHED types so that at boot-up, we can map memories outside system memory at page level granularity Previously the mapping was limiting to section level, which creates unnecessary additional mapping for which physical memory may not present. On the newer ARM with speculation, this is dangerous and can result in untraceable aborts.

When the policy for user space is to ignore misaligned accesses from user space, the processor then performs a documented rotation on the accessed data. This is the result of the access being trapped, and the kernel disabling the alignment trap before returning to user space again. In kernel space we always want misaligned accesses to be fixed up. This is enforced by always re-enabling the alignment trap on every entry into kernel space from user space. No such re-enabling is performed when an exception occurs while already in kernel space as the alignment trap is always supposed to be enabled in that case. There is however a small race window when a misaligned access in user space is trapped and the alignment trap disabled, but the CPU didn't return to user space just yet. Any exception would be entered from kernel space at that point and the kernel would then execute with the alignment trap disabled. Thanks to Maxime Bizon <mbizon@freebox.fr> for providing a test module that made this issue reproducible.

Use a correct udelay value to get bus speed around 100KHz. The udelay value was most likely copied from the older devices, but the 9g45 is signicantly faster (400MHz, DDR, ..), so a udelay of 2 gives a bus speed of around 190KHz, which is too fast for some devices. A udelay value of 5 gives a bus speed of around 90KHz here.

When using simultaneously the two DMA channels on a same engine, some transfers are never completed. For example, an endless lock can occur while writing heavily on a RAID5 array (with async-tx offload support enabled). Note that this issue can also be reproduced by using the DMA test client. On a same engine, the interrupt cause register is shared between two DMA channels. This patch make sure that the cause bit is only cleared for the requested channel.

The support for the 2 pcie port of the 6282 has broken i/o port by switching *_IO_PHYS_BASE and *_IO_BUS_BASE. In fact, the patches reintroduced the same bug solved by commit 35f029e2. So, I'm adding back *_IO_BUS_BASE in resource declaration and fix definition of KIRKWOOD_PCIE1_IO_BUS_BASE. With this change, the xgi card on my t5325 is working again.

ARMv7 onwards requires that there are no aliases to the same physical location using different memory types (i.e. Normal vs Strongly Ordered). Access to SO mappings when the unaligned accesses are handled in hardware is also Unpredictable (pgprot_noncached() mappings in user space). The /dev/mem driver requires uncached mappings with O_SYNC. The patch implements the phys_mem_access_prot() function which generates Strongly Ordered memory attributes if !pfn_valid() (independent of O_SYNC) and Normal Noncacheable (writecombine) if O_SYNC.

Clearing bit 22 in the PL310 Auxiliary Control register (shared attribute override enable) has the side effect of transforming Normal Shared Non-cacheable reads into Cacheable no-allocate reads. Coherent DMA buffers in Linux always have a Cacheable alias via the kernel linear mapping and the processor can speculatively load cache lines into the PL310 controller. With bit 22 cleared, Non-cacheable reads would unexpectedly hit such cache lines leading to buffer corruption.

On the r2p0, r2p1 and r2p2 versions of the Cortex-A9, data corruption can occur if a shared cache line is replaced on one CPU as another CPU is accessing it. This workaround sets two bits in the diagnostic register of the Cortex-A9, reducing the linefill issuing capabilities of the processor and avoiding the erroneous behaviour.
