Usually, freescale rapidio endpoint can support one or two 1x or 4X
LP-Serial link interfaces, and rapidio message transactions can be
implemented by two message units. This adds the support of two
rapidio ports and initializes message unit 0 and message unit 1. And
these ports and message units can work simultaneously.

The Freescale PowerPC RapidIO controller consists of a RapidIO endpoint and
a RapidIO message unit(RMU). Or use RapidIO message manager(RMan) to
replace the RMU in DPAA architecture. Therefore, we should split the code
into two function modules according to the hardware architecture. Add new
struct for RMU module, and new initialization function to set up RMU
module. This policy is very conducive to adding new module like RMan, or
adding multi-ports or message units support.

The driver for the Freescale P3060 QDS got added by commit 96cc017c5b
("[...] Add support for P3060QDS board"). Its Kconfig entry selects
MPC8xxx_GPIO. But at the time that driver got added MPC8xxx_GPIO was
already renamed to GPIO_MPC8XXX, by commit c68308dd50c ("gpio: move
mpc8xxx/512x gpio driver to drivers/gpio").
So make this driver select GPIO_MPC8XXX.

P1023 external IRQ[4:6, 11] are not pin out, but the interrupts are
utilized by the PCIe controllers. As they are not exposed as pins we
need to set them as active-high (internal to the SoC these interrupts
are pulled down).
IRQs[0:3,7:10] are pulled up on the board so we have them set as
active-low.

virtio-pci: make reset operation safer
virtio-mmio: Correct the name of the guest features selector
virtio: add HAS_IOMEM dependency to MMIO platform bus driver
|
|
virtio pci device reset actually just does an I/O
write, which in PCI is really posted, that is it
can complete on CPU before the device has received it.
Further, interrupts might have been pending on
another CPU, so device callback might get invoked after reset.
This conflicts with how drivers use reset, which is typically:
reset
unregister
a callback running after reset completed can race with
unregister, potentially leading to use after free bugs.
Fix by flushing out the write, and flushing pending interrupts.
This assumes that device is never reset from
its vq/config callbacks, or in parallel with being
added/removed, document this assumption.

eCryptfs: Extend array bounds for all filename chars
eCryptfs: Flush file in vma close
eCryptfs: Prevent file create race condition
|
|
From mhalcrow's original commit message:
Characters with ASCII values greater than the size of
filename_rev_map[] are valid filename characters.
ecryptfs_decode_from_filename() will access kernel memory beyond
that array, and ecryptfs_parse_tag_70_packet() will then decrypt
those characters. The attacker, using the FNEK of the crafted file,
can then re-encrypt the characters to reveal the kernel memory past
the end of the filename_rev_map[] array. I expect low security
impact since this array is statically allocated in the text area,
and the amount of memory past the array that is accessible is
limited by the largest possible ASCII filename character.
This patch solves the issue reported by mhalcrow but with an
implementation suggested by Linus to simply extend the length of
filename_rev_map[] to 256. Characters greater than 0x7A are mapped to
0x00, which is how invalid characters less than 0x7A were previously
being handled.

Dirty pages weren't being written back when an mmap'ed eCryptfs file was
closed before the mapping was unmapped. Since f_ops->flush() is not
called by the munmap() path, the lower file was simply being released.
This patch flushes the eCryptfs file in the vm_ops->close() path.

The file creation path prematurely called d_instantiate() and
unlock_new_inode() before the eCryptfs inode info was fully
allocated and initialized and before the eCryptfs metadata was written
to the lower file.
This could result in race conditions in subsequent file and inode
operations leading to unexpected error conditions or a null pointer
dereference while attempting to use the unallocated memory.

Count of selector voltage is required for regulator_set_voltage
to work via set_voltage_sel. VDD1/2 currently have it as zero,
so regulator_set_voltage won't work for VDD1/2.
Update count (n_voltages) for VDD1/2.
Output Voltage = (step value * 12.5 mV + 562.5 mV) * gain
With above expr, number of voltages that can be selected is
step value count * gain count
constant for gain count will be called VDD1_2_NUM_VOLT_COARSE
existing constant for step value count is VDD1_2_NUM_VOLTS,
use VDD1_2_NUM_VOLT_FINE instead to make clear that step value
is not the only component in deciding selectable voltage count

This reverts commit dc9372808412edbc653a675a526c2ee6c0c14a91.
As requested by Ben Herrenschmidt:
"This breaks some powerpc platforms at least. The practice of having
a node provide an explicit "interrupt-parent" property pointing to
itself is an old trick that we've used in the past to allow a
device-node to have interrupts routed to different controllers.
In that case, the node also contains an interrupt-map, so the node is
its own parent, the interrupt resolution hits the map, which then can
route each individual interrupt to a different parent."
Grant says:
"Ah, nuts, yes that is broken then. Yes, please revert the commit and
Rob & I will come up with a better solution.
Rob, I think it can be done by explicitly checking for np ==
desc->interrupt_parent in of_irq_init() instead of relying on
of_irq_find_parent() returning NULL."
