This patch extends the start and end address of initrd to be page aligned,
so that we can free all memory including the un-page aligned head or tail
page of initrd, if the start or end address of initrd are not page
aligned, the page can't be freed by free_initrd_mem() function.

This patch changes the __init_end address to a
page align address, so that free_initmem() can
free the whole .init section, because if the end
address is not page aligned, it will round down to
a page align address, then the tail unligned page
will not be freed.

When both 'cache-size' and 'cache-sets' are specified for a L2 cache
controller node, parse those properties and set up the
set size based on which type of L2 cache controller we are using.
Update the L2 cache controller Device Tree binding with the optional
'cache-size', 'cache-sets', 'cache-block-size' and 'cache-line-size'
properties. These come from the ePAPR specification.
Using the cache size, number of sets and cache line size we can
calculate desired associativity of the L2 cache. This is done
by the calculation:
set size = cache size / sets
ways = set size / line size
way size = cache size / ways = sets * line size
associativity = cache size / way size
Example output from the PB1176 DT that look like this:
L2: l2-cache {
compatible = "arm,l220-cache";
(...)
arm,override-auxreg;
cache-size = <131072>; // 128kB
cache-sets = <512>;
cache-line-size = <32>;
};
Ends up like this:
L2C OF: override cache size: 131072 bytes (128KB)
L2C OF: override line size: 32 bytes
L2C OF: override way size: 16384 bytes (16KB)
L2C OF: override associativity: 8
L2C: DT/platform modifies aux control register: 0x02020fff -> 0x02030fff
L2C-220 cache controller enabled, 8 ways, 128 kB
L2C-220: CACHE_ID 0x41000486, AUX_CTRL 0x06030fff
Which is consistent with the value earlier hardcoded for the
PB1176 platform.
This patch is an extended version based on the initial patch

This change adds support for clock_gettime with CLOCK_REALTIME
and CLOCK_MONOTONIC using vDSO. It also updates the vdso
struct nomenclature used for the clocks to match the x86 code
to keep it easier to update going forward.
We also support the *_COARSE clockid_t, for apps that want speed
but aren't concerned about fine-grained timestamps; this saves

hisi has a general dependency on ARCH_MULTIPLATFORM, which is
problematic when building a kernel for non-V7 platforms but selecting
drivers that might conflict with other architecture levels.
In this case, it broke my (still out of tree) patch set that
enables V7M multiplatform support, since that does not enable
MULTI_IRQ support:
arch/arm/kernel/built-in.o: In function `set_handle_irq':
arch/arm/kernel/irq.c:125: undefined reference to `handle_arch_irq'
arch/arm/kernel/built-in.o: In function `setup_arch':
arch/arm/kernel/setup.c:965: undefined reference to `handle_arch_irq'
Since all hisilicon platforms are ARMv7 based, we can avoid this
problem by just making the dependency more specific.

Both strncpy and strlcpy suffer from the fact that they do
partial copies of strings into the destination when the target
buffer is too small. This is frequently pointless since an
overflow of the target buffer may make the result invalid.
strncpy() makes it relatively hard to even detect the error
condition, and with strlcpy() you have to duplicate the buffer
size parameter to test to see if the result exceeds it.
By returning zero in the failure case, we both make testing
for it easy, and by simply not copying anything in that case,
we make it mandatory for callers to test the error code.
To catch lazy programmers who don't check, we also place a NUL at
the start of the destination buffer (if there is space) to
ensure that the result is an invalid string.
At some point it may make sense to promote strscpy() to
a global platform-independent function, but other than the
reviewers, no one was interested on LKML, so for now leave
the strscpy() function as file-static.

The "by8" CTR AVX implementation fails to propperly handle counter
overflows. That was the reason it got disabled in commit 7da4b29d49
("crypto: aesni - disable "by8" AVX CTR optimization").
Fix the overflow handling by incrementing the counter block as a double
quad word, i.e. a 128 bit, and testing for overflows afterwards. We need
to use VPTEST to do so as VPADD* does not set the flags itself and
silently drops the carry bit.
As this change adds branches to the hot path, minor performance
regressions might be a side effect. But, OTOH, we now have a conforming
implementation -- the preferable goal.
A tcrypt test on a SandyBridge system (i7-2620M) showed almost identical
numbers for the old and this version with differences within the noise
range. A dm-crypt test with the fixed version gave even slightly better
results for this version. So the performance impact might not be as big
as expected.

This is caused by the compiler spilling it's literal pool too far away
from the site which is trying to reference it with a PC relative load.
This arises because the compiler is underestimating the size of the
inline assembler code present, which apparently it approximates as 4
bytes per line or instruction.
We fix this problem by moving the operations which generate more than
4 bytes out of the text section. Specifically, moving the .ascii

Here's our last set of fixes for 3.17. Most of these are for TI platforms,
fixing some noisy Kconfig issues, runtime clock and power issues on
several platforms and NAND timings on DRA7.
There are also a couple of bug fixes for i.MX, one for QCOM and a small
fix to avoid section mismatch noise on PXA.
Diffstat looks large, partially due to some tables being updated and
thus touching many lines. The qcom gsbi change also restructures clock
management a bit and thus touches a bunch of lines.
All in all, a bit more changes than we'd like at this point, but nothing
stands out as risky either so it seems like the right thing to send it
up now instead of holding it to the merge window.

Please pull this batch of updates intended for the 3.18 stream...
For the mac80211 bits, Johannes says:
"This time, I have some rate minstrel improvements, support for a very
small feature from CCX that Steinar reverse-engineered, dynamic ACK
timeout support, a number of changes for TDLS, early support for radio
resource measurement and many fixes. Also, I'm changing a number of
places to clear key memory when it's freed and Intel claims copyright
for code they developed."
For the bluetooth bits, Johan says:
"Here are some more patches intended for 3.18. Most of them are cleanups
or fixes for SMP. The only exception is a fix for BR/EDR L2CAP fixed
channels which should now work better together with the L2CAP
information request procedure."
For the iwlwifi bits, Emmanuel says:
"I fix here dvm which was broken by my last pull request. Arik
continues to work on TDLS and Luca solved a few issues in CT-Kill. Eyal
keeps digging into rate scaling code, more to come soon. Besides this,
nothing really special here."
Beyond that, there are the usual big batches of updates to ath9k, b43,
mwifiex, and wil6210 as well as a handful of other bits here and there.
Also, rtlwifi gets some btcoexist attention from Larry.
Please let me know if there are problems!

CALLER_ADDRESSx for x > 1 returns NULL which doesn't do much harm.
The drawback of implementing a fix (i.e. use unwind tables to implement CALLER_ADDRESSx) is that much of the unwinder code would need to be marked as not

With compilers which follow the C99 standard (like modern versions of gcc and

The current aarch64 calculation for VTTBR_BADDR_MASK masks only 39 bits
and not all the bits in the PA range. This is clearly a bug that
manifests itself on systems that allocate memory in the higher address
space range.
[ Modified from Joel's original patch to be based on PHYS_MASK_SHIFT
instead of a hard-coded value and to move the alignment check of the
allocation to mmu.c. Also added a comment explaining why we hardcode
the IPA range and changed the stage-2 pgd allocation to be based on
the 40 bit IPA range instead of the maximum possible 48 bit PA range.

Commit bbd426f542 "MIPS: Simplify FP context access" modified the
SIFROMREG & SIFROMHREG macros such that they return unsigned rather
than signed 32b integers. I had believed that to be fine, but
inadvertently missed the MFC1 & MFHC1 cases which write to a struct
pt_regs regs element. On MIPS32 this is fine, but on 64 bit those
saved regs' fields are 64 bit wide. Using unsigned values caused the
32 bit value from the FP register to be zero rather than sign extended
as the architecture specifies, causing incorrect emulation of the
MFC1 & MFHc1 instructions. Fix by reintroducing the casts to signed
integers, and therefore the sign extension.

There are other forms that are supported on different ARM instruction sets but
generally the kernel just uses mcr as it is supported in all ARM instruction

Without this patch, each root port and the device connected directly to it seem
to be located on a shared (virtual) bus #0. It creates problems with enabling
devices (the PCI code doesn't know that the root bridge must be enabled in order
to access other devices).
The PCIe topology shown by lspci doesn't reflect reality, e.g.:
0000:00:00.0 PCI bridge: Cavium Networks Device 3400
0000:00:01.0 PCI bridge: Texas Instruments XIO2001 PCI Express-to-PCI Bridge
