This reverts commit 941f5f0f6e.
Sadly, it turns out that we really can't just do the cross-CPU IPI to
all CPU's to get their proper frequencies, because it's much too
expensive on systems with lots of cores.
So we'll have to revert this for now, and revisit it using a smarter
model (probably doing one system-wide IPI at open time, and doing all
the frequency calculations in parallel).

Add the PCI write end padding flag to device_cap_flags enum and set it

During WQ/QP creation, set that capability for WQ/QP if user requested
it and HW supports it.
PCI write end padding modification is not supported for now. There's no
such flag for a QP but for a WQ, create and modify use the same flag.

There are root complexes that are able to optimize their
performance when incoming data is multiple full cache lines.
PCI write end padding is the device's ability to pad the ending of
incoming packets (scatter) to full cache line such that the last
upstream write generated by an incoming packet will be a full cache
line.
Add a relevant entry to ib_device_cap_flags to report such capability
of an RDMA device.
Add the QP and WQ create flags:
* A QP/WQ created with a scatter end padding flag will cause
HW to pad the last upstream write generated by a packet to cache line.
User should consider several factors before activating this feature:
- In case of high CPU memory load (which may cause PCI back pressure in
turn), if a large percent of the writes are partial cache line, this
feature should be checked as an optional solution.
- This feature might reduce performance if most packets are between one
and two cache lines and PCIe throughput has reached its maximum
capacity. E.g. 65B packet from the network port will lead to 128B
write on PCIe, which may cause traffic on PCIe to reach high
throughput.

overwrite later by irrelevant value assignment. Hence, ingress packets
which gets to the RSS QP will be steered then to a garbage QPN.
The patch fixes this by skipping the above assignment when a RSS QP is
modified, also, the RSS context's attributes assignments are relocated
just before the context is posted to avoid future issues like this.
Additionally, this patch takes the opportunity to change the code to be
disciplined to the device's manual and assigns the RSS QP context just at

Rebooting into a new kernel with kexec fails (system dies) if tried on
a machine that has no-execute support. Reason for this is that the so
called datamover code gets executed with DAT on (MMU is active) and
the page that contains the datamover is marked as non-executable.
Therefore when branching into the datamover an unexpected program
check happens and afterwards the machine is dead.
This can be simply avoided by disabling DAT, which also disables any
no-execute checks, just before the datamover gets executed.
In fact the first thing done by the datamover is to disable DAT. The
code in the datamover that disables DAT can be removed as well.

There are several bugs with control register handling with respect to
transactional execution:
- on task switch update_per_regs() is only called if the next task has
an mm (is not a kernel thread). This however is incorrect. This
breaks e.g. for user mode helper handling, where the kernel creates
a kernel thread and then execve's a user space program. Control
register contents related to transactional execution won't be
updated on execve. If the previous task ran with transactional
execution disabled then the new task will also run with
transactional execution disabled, which is incorrect. Therefore call
update_per_regs() unconditionally within switch_to().
- on startup the transactional execution facility is not enabled for
the idle thread. This is not really a bug, but an inconsistency to
other facilities. Therefore enable the facility if it is available.
- on fork the new thread's per_flags field is not cleared. This means
that a child process inherits the PER_FLAG_NO_TE flag. This flag can
be set with a ptrace request to disable transactional execution for
the current process. It should not be inherited by new child
processes in order to be consistent with the handling of all other
PER related debugging options. Therefore clear the per_flags field in
copy_thread_tls().

GPIO_LOOKUP_IDX("gpio", GPIO_GPIO21, NULL, 0,
This is what happened:
commit b2e6355559
"i2c: gpio: Convert to use descriptors"
commit 4d0ce62c0a
"i2c: gpio: Augment all boardfiles to use open drain"
together uncovered an old bug in the Simpad board
file: as theGPIO_LOOKUP_IDX() encodes GPIO offsets
on gpiochips in an u16 (see <linux/gpio/machine.h>)
these GPIO "numbers" does not fit, since in
arch/arm/mach-sa1100/include/mach/SA-1100.h it is
defined as:
#define GPIO_GPIO(Nb) (0x00000001 << (Nb))
(...)
#define GPIO_GPIO21 GPIO_GPIO(21) /* GPIO [21] */
This is however provably wrong, since the i2c-gpio
driver uses proper GPIO numbers, albeit earlier from
the global number space, whereas this GPIO_GPIO21
is the local line offset in the GPIO register, which
is used in other code but certainly not in the
gpiolib GPIO driver in drivers/gpio/gpio-sa1100.c, which
has code like this:
static void sa1100_gpio_set(struct gpio_chip *chip,
unsigned offset, int value)
{
int reg = value ? R_GPSR : R_GPCR;
writel_relaxed(BIT(offset),
sa1100_gpio_chip(chip)->membase + reg);
}
So far everything however compiled fine as an unsigned
int was used to pass the GPIO numbers in
struct i2c_gpio_platform_data. We can trace the actual error
back to
commit dbd406f9d0
"ARM: 7025/1: simpad: add GPIO based device definitions."
This added the i2c_gpio with the wrong offsets.
This commit was before the SA1100 was converted to use
the gpiolib, but as can be seen from the contemporary
gpio.c in mach-sa1100, it was already using:
static int sa1100_gpio_get(struct gpio_chip *chip,
unsigned offset)
{
return GPLR & GPIO_GPIO(offset);
}
And GPIO_GPIO() is essentially the BIT() macro.
