This patch add the core driver for the c67x00 USB OTG controller. The core
driver is responsible for the platform bus binding and creating either
USB HCD or USB Gadget instances for each of the serial interface engines
on the chip.This driver does not directly implement the HCD or gadget behaviours; it
just controls access to the chip.Signed-off-by: Peter Korsgaard

This device descriptor was added by the recent USB Link Power Management (LPM)
ECN. It indicates whether the USB device supports LPM.This descriptor is grouped under a Binary Device Object Store (BOS) descriptor.
Update the BOS comments to indicate any USB device (not just wireless USB
devices) can implement BOS descriptors.Signed-off-by: Sarah Sharp

Add a new sysfs_streq() string comparison function, which ignores
the trailing newlines found in sysfs inputs. By example:sysfs_streq("a", "b") ==> false
sysfs_streq("a", "a") ==> true
sysfs_streq("a", "a\n") ==> true
sysfs_streq("a\n", "a") ==> trueThis is intended to simplify parsing of sysfs inputs, letting them
avoid the need to manually strip off newlines from inputs.Signed-off-by: David Brownell

Remove the leap second handling from second_overflow(), which doesn't have to
check for it every second anymore. With CONFIG_NO_HZ this also makes sure the
leap second is handled close to the full second. Additionally this makes it

time_offset is already a 64bit value but its resolution barely used, so this
makes better use of it by replacing SHIFT_UPDATE with TICK_LENGTH_SHIFT.Side note: the SHIFT_HZ in SHIFT_UPDATE was incorrect for CONFIG_NO_HZ and the
primary reason for changing time_offset to 64bit to avoid the overflow.Signed-off-by: Roman Zippel

This changes time_freq to a 64bit value and makes it static (the only outside
user had no real need to modify it). Intermediate values were already 64bit,
so the change isn't that big, but it saves a little in shifts by replacing
SHIFT_NSEC with TICK_LENGTH_SHIFT. PPM_SCALE is then used to convert between
user space and kernel space representation.Signed-off-by: Roman Zippel

This adds a few more things from the ntp nanokernel related to user space.
It's now possible to select the resolution used of some values via STA_NANO
and the kernel reports in which mode it works (pll/fll).If some values for adjtimex() are outside the acceptable range, they are now
simply normalized instead of letting the syscall fail. I removed
MOD_CLKA/MOD_CLKB as the mapping didn't really makes any sense, the kernel
doesn't support setting the clock.Signed-off-by: Roman Zippel

x86 is the only arch right now, which provides an optimized for
div_long_long_rem and it has the downside that one has to be very careful that
the divide doesn't overflow.The API is a little akward, as the arguments for the unsigned divide are
signed. The signed version also doesn't handle a negative divisor and
produces worse code on 64bit archs.There is little incentive to keep this API alive, so this converts the few
users to the new API.Signed-off-by: Roman Zippel

Rename div64_64 to div64_u64 to make it consistent with the other divide
functions, so it clearly includes the type of the divide. Move its definition

They can still override it of course, but the duplicated declarations are
avoided.Signed-off-by: Roman Zippel

The current do_div doesn't explicitly say that it's unsigned and the signed
counterpart is missing, which is e.g. needed when dealing with time values.This introduces 64bit signed/unsigned divide functions which also attempts to
cleanup the somewhat awkward calling API, which often requires the use of
temporary variables for the dividend. To avoid the need for temporary
variables everywhere for the remainder, each divide variant also provides a
version which doesn't return the remainder.Each architecture can now provide optimized versions of these function,
otherwise generic fallback implementations will be used.As an example I provided an alternative for the current x86 divide, which
avoids the asm casts and using an union allows gcc to generate better code.
It also avoids the upper divde in a few more cases, where the result is known
(i.e. upper quotient is zero).Signed-off-by: Roman Zippel

When I backed out of using the generic sg chaining (as it isn't currently
portable) and introduced scatterwalk_sg_chain/scatterwalk_sg_next I left
out the sg_is_last check in the latter. This causes it to potentially
dereference beyond the end of the sg array.As most uses of scatterwalk_sg_next are bound by an overall length, this
only affected the chaining code in authenc and eseqiv. Thanks to Patrick
McHardy for identifying this problem.This patch also clears the "last" bit on the head of the chained list as
it's no longer last. This also went missing in scatterwalk_sg_chain and
is present in sg_chain.Signed-off-by: Herbert Xu

Since recent smpboot 32/64-bit merge, my dual Xeon with HT has been
booting only 2 of its 4 cpus (when running an i386 kernel; but x86_64
is okay). J.A. Magallón reports the same.native_cpu_up: bad cpu 2
native_cpu_up: bad cpu 3The mach-default cpu_present_to_apicid() was just returning cpu number
(2, 3) instead of apicid (6, 7): looks like we now need the x86_64 code
even for the i386 case.Comparing with other versions of cpu_present_to_apicid(), it seems a
good idea to include an NR_CPUS test too, since cpu_present() doesn't
include that; but that wasn't a problem here, and may no problem at all.Prior to that smpboot merge, my Xeon booted the two HT siblings on one
physical first, then the two siblings on the other physical after - when
i386, but alternated them when x86_64. Since the merge, the x86_64
sequence is unchanged, but the i386 sequence is now like x86_64.I prefer this consistency, and I prefer the new sequence: booting with
maxcpus=2 then uses the independent physicals without HT sharing.Signed-off-by: Hugh Dickins
