Hi all,
Changes since 20140702:
My fixes tree contains:
powerpc: Disable RELOCATABLE for COMPILE_TEST with PPC64
The staging tree still had its build failure for which I disabled a driver.
The akpm-current tree gained a build failure for which I applied a patch.

Hi Andrew,
After merging the akpm-current tree, today's linux-next build (x86_64
allmodconfig) failed like this:
/bin/sh: /scratch/sfr/next/scripts/basic/bin2c: No such file or directory
Presumably caused by commit 572a8e0147f8 ("bin2c: move bin2c in

Hi,
Changes since v2 (in patch 3):
- Replace BIT(bits / 8) with (1 << (bits / 8)) as pointed out by Takashi
- Use switch (addr_widths) to filter non valid physical widths, like -EINVAL or
widths not dividable by 8.
The same check could be done with:
if (bits > 0 && bits <=64 && !(bits % 8)
params_physical_width() is available via pcm_params.h

In case of _3LE/_3BE formats the samples are stored in 3 consecutive bytes
without padding it to 4 bytes. This means that the DMA needs to be able to
support 3 bytes word length in order to read/write the samples from memory
correctly. Originally the code treated 24 bits physical length samples as
eDMA can be configured for 3bytes word size for source and destination.

Add DMA_SLAVE_BUSWIDTH_3_BYTES to dma_slave_buswidth for engines and users
to select 3 bytes as bus width.
For example eDMA can be configured to use 3bytes mode and in audio we have
formats stored on 3bytes in memory (_XXX_3LE) where this new bus width can
be used.

Based on the dma_slave_caps's addr_widths queried from the dma driver
prepare the hw.formats mask to include only formats which is supported by
the DMA engine.
In case the dma driver does not implement the slave_caps the default
assumption is that it supports 1, 2 and 4 bytes widths.

- Regarding the comments to separate ECAM functionality,
I have sent a separate patch and it is decided to implement
it later. The patch is here,
https://lkml.org/lkml/2014/5/18/54
This small patch completes #defines for Control/Status Register,
adds comments for the missing ones there and on the Interrupt Mask
Register and additionally corrects "#define ICE1712_SERR_LEVEL 0x04 -> 0x08",

When the system is too busy to complete the urb, the tx timout function
would be called. This causes the other tx urbs would be killed, too.
Increase the tx timeout to avoid it.

If RTIT_CTL.TraceEn=1, any attempt to read or write the LBR or LER MSRs,

Since Intel PT can be enabled/disabled at runtime, LBR MSRs have to be

With -cpu host KVM reports LBR and offcore support, so the perf driver may
accesses the LBR and offcore MSRs.
However, there is no LBR and offcore virtualization support yet. This could

As a workaround, KVM just simply ignore the LBR and offcore_rsp MSRs

x86, perf: Protect LBR and offcore rsp against KVM lying
With -cpu host, KVM reports LBR and offcore support, if the host has support.
When the guest perf driver tries to access LBR or offcore_rsp MSR,
it #GPs all MSR accesses,since KVM doesn't handle LBR and offcore support.
So

A page fault can crash the kernel very early if an NX bit is set in a
page table entry, if the CPU doesn't support NX (or if NX support is
disabled in the CPU). Move the call to x86_configure_nx() earlier
than parse_setup_data(), since that calls early_memremap().

Dear RT Folks,
This is the RT stable review cycle of patch 3.4.94-rt117-rc1.
Please scream at me if I messed something up. Please test the patches too.
The -rc release will be uploaded to kernel.org and will be deleted when
the final release is out. This is just a review release (or release
3.4.94-rt117-rc1 stable review patch.
If anyone has any objections, please let me know.

In an rt-kernel with CONFIG_MISSED_TIMER_OFFSETS_HIST enabled,
__hrtimer_start_range_ns() now crashes, as new_base is not assigned
before it is used.
Tested-by:
3.4.94-rt117-rc1 stable review patch.
If anyone has any objections, please let me know.

This removes the FIXME message above ocpi_enable being declared
for proper locking in this function. As of the current kernel
verisons there is no need for locking as only one driver uses
this function currently and therefore there is no need for real
locking requirements.

But actually it doesn't need to be pinned in memory.

This adds a hopefully helpful comment above the (seemingly weird)
compiler flag selection logic.
