Basically it's the same as the original DS75 but much faster.
Signed-off-by: Jean Delvare
Acked-by: Guenter Roeck -
Most LM75-compatible chips can either sample much faster or with a
much better resolution than the original LM75 chip. So far the lm75
driver did not let the user take benefit of these improvements. Do it
now.I decided to almost always configure the chip to use the best
resolution possible, which also means the longest sample time. The
only chips for which I didn't are the DS75, DS1775 and STDS75, because
they are really too slow in 12-bit mode (1.2 to 1.5 second worst case)
so I went for 11-bit mode as a more reasonable tradeoff. This choice is
dictated by the fact that the hwmon subsystem is meant for system
monitoring, it has never been supposed to be ultra-fast, and as a
matter of fact we do cache the sampled values in almost all drivers.If anyone isn't pleased with these default settings, they can always
introduce a platform data structure or DT support for the lm75. That
being said, it seems nobody ever complained that the driver wouldn't
refresh the value faster than every 1.5 second, and the change made
it faster for all chips even in 12-bit mode, so I don't expect any
complaint.Signed-off-by: Jean Delvare

Prepare the lm75 driver to support per-chip resolution and sample
time. For now we only make the code generic enough to support it, but
we still use the same, unchanged resolution (9-bit) and sample time
(1.5 s) for all chips.Signed-off-by: Jean Delvare
Acked-by: Guenter Roeck -
There is no standard for the configuration register bits of LM75-like
chips. We shouldn't blindly clear bits setting the resolution as they
are either unused or used for something else on some of the supported
chips.So, switch to per-chip configuration initialization. This will allow
for better tuning later, for example using more resolution bits when
available.Signed-off-by: Jean Delvare

Pull nfsd changes from J Bruce Fields:
"Highlights include:- Some more DRC cleanup and performance work from Jeff Layton
- A gss-proxy upcall from Simo Sorce: currently krb5 mounts to the
server using credentials from Active Directory often fail due to
limitations of the svcgssd upcall interface. This replacement
lifts those limitations. The existing upcall is still supported
for backwards compatibility.- More NFSv4.1 support: at this point, if a user with a current
client who upgrades from 4.0 to 4.1 should see no regressions. In
theory we do everything a 4.1 server is required to do. Patches
for a couple minor exceptions are ready for 3.11, and with those
and some more testing I'd like to turn 4.1 on by default in 3.11."Fix up semantic conflict as per Stephen Rothwell and linux-next:
Commit 030d794bf498 ("SUNRPC: Use gssproxy upcall for server RPCGSS
authentication") adds two new users of "PDE(inode)->data", but we're
supposed to use "PDE_DATA(inode)" instead since commit d9dda78bad87
("procfs: new helper - PDE_DATA(inode)").The old PDE() macro is no longer available since commit c30480b92cf4

Pull i2c changes from Wolfram Sang:
- an arbitration driver. While the driver is quite simple, it caused
discussion if we need additional arbitration on top of the one
specified in the I2C standard. Conclusion is that I accept a few
generic mechanisms, but not very specific ones.- the core lost the detach_adapter() call. It has no users anymore and
was in the way for other cleanups. attach_adapter() is sadly still
there since there are users waiting to be converted.- the core gained a bus recovery infrastructure. I2C defines a way to
recover if the data line is stalled. This mechanism is now in the
core and drivers can now pass some data to make use of it.- bigger driver cleanups for designware, s3c2410

return gpmc_cs_set_timings(cs, t);.....
ret = gpmc_set_async_mode(gpmc_onenand_data->cs, &t);
if (IS_ERR_VALUE(ret))
return ret;So, gpmc_cs_set_timings() thinks any negative return value is an error,
but where we check that in higher levels, only a limited range are
errors...There is only _one_ use of IS_ERR_VALUE() in arch/arm which is really
appropriate, and that is in arch/arm/include/asm/syscall.h:static inline long syscall_get_error(struct task_struct *task,
struct pt_regs *regs)
{
unsigned long error = regs->ARM_r0;
return IS_ERR_VALUE(error) ? error : 0;
}because this function really does have to differentiate between error
return values and addresses which look like negative numbers (eg, from
mmap()).So, here's a patch to remove them from OMAP, except for the above.

omap_hwmod_lookup() only returns NULL on error, never an error pointer.
Checking the returned pointer using IS_ERR_OR_NULL() is needless
overhead. Use a simple !ptr check instead.OMAP devices (oh->od) always have a valid platform device attached (see
omap_device_alloc()) so there's no point validating the platform device
pointer (we will have already oopsed long before if this is not the
case here.)Lastly, oh->od is only ever NULL or a valid omap device pointer - 'oh'
comes from the statically declared hwmod tables, and the pointer is
only filled in by omap_device_alloc() at a point where the omap device
pointer must be valid.Signed-off-by: Russell King

During early init, we would incorrectly set the NX bit even if the NX
feature was not supported. Instead, only set this bit if NX is
actually available and enabled. We already do very early detection of
the NX bit to enable it in EFER, this simply extends this detection to
the early page table mask.Reported-by: Fernando Luis Vázquez Cao

The git commite7a5cd063c7b4c58417f674821d63f5eb6747e37
("x86-64, gdt: Store/load GDT for ACPI S3 or hibernate/resume path
is not needed.") assumes that for the hibernate path the booting
kernel and the resuming kernel MUST be the same. That is certainly
the case for a 32-bit kernel (see check_image_kernel and
CONFIG_ARCH_HIBERNATION_HEADER config option).However for 64-bit kernels it is OK to have a different kernel
version (and size of the image) of the booting and resuming kernels.
Hence the above mentioned git commit introduces an regression.This patch fixes it by introducing a 'struct desc_ptr gdt_desc'
back in the 'struct saved_context'. However instead of having in the
'save_processor_state' and 'restore_processor_state' the
store/load_gdt calls, we are only saving the GDT in the
save_processor_state.For the restore path the lgdt operation is done in
hibernate_asm_[32|64].S in the 'restore_registers' path.The apt reader of this description will recognize that only 64-bit
kernels need this treatment, not 32-bit. This patch adds the logic
in the 32-bit path to be more similar to 64-bit so that in the future
the unification process can take advantage of this.[ hpa: this also reverts an inadvertent on-disk format change ]

Pull powerpc update from Benjamin Herrenschmidt:
"The main highlights this time around are:- A pile of addition POWER8 bits and nits, such as updated
performance counter support (Michael Ellerman), new branch history
buffer support (Anshuman Khandual), base support for the new PCI
host bridge when not using the hypervisor (Gavin Shan) and other
random related bits and fixes from various contributors.- Some rework of our page table format by Aneesh Kumar which fixes a
thing or two and paves the way for THP support. THP itself will
not make it this time around however.- More Freescale updates, including Altivec support on the new e6500
cores, new PCI controller support, and a pile of new boards support
and updates.- The usual batch of trivial cleanups & fixes"

Pull ARM SoC multiplatform updates from Olof Johansson:
"More multiplatform enablement for ARM platforms. The ones converted
in this branch are:- bcm2835

One of the larger platforms remaining is Samsung Exynos, and there are
a bunch of supporting patches in this merge window for it. There was
a patch in this branch to a early version of multiplatform conversion,
but it ended up being reverted due to need of more bake time. The
revert commit is part of the branch since it would have required
rebasing multiple dependent branches and they were stable by then"* tag 'multiplatform-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (70 commits)
