xhci: Regression fix for 3.13
Hi Greg,
In 3.12-rc5, I merged a patch that was supposed to fix spurious reboots on
shutdown on HP systems. The quirk was broadly applied to all Intel Haswell and
Haswell ULT systems. Turns out the quirk caused non-HP systems to reboot on
suspend. They shutdown just fine with the quirk patch reverted. This patch
narrows the xHCI quirk to only run on HP systems.
Sometimes fixing firmware issues feels like plugging holes in a leaky boat.

Commit 011c2282c74d changed the way refcounting on imported dma_bufs
works, and this hadn't been spotted while forward-porting Armada.
Reflect the changes in that commit into the Armada driver.

Not all channels have been initialized, so far, especially when aamix
NID itself doesn't have amps but its leaves have. This patch fixes
these holes. Otherwise you might get unexpected loopback inputs,
e.g. from surround channels.

The basename() implementation varies a lot between systems.
The Linux man page says: "basename may modify the content of the path,
so it may be desirable to pass a copy when calling the function".
On some other systems, the returned address may come from an internal
buffer which can be reused in subsequent calls, thus the results should
also be copied.
The dso__set_basename() function was not doing this causing problems
on some systems with wrong library names being shown by perf report,
such as on Android systems.
This patch fixes the problem.
The patch is relative to tip.git.
In v2, we clean up the comments based on Ingo's feedback.

Same reason as for dso->short_name, it may point to a const string, and
in most places it is treated as const, i.e. it is just accessed for

We've got regression reports that my previous fix for spurious wakeups
after S5 on HP Haswell machines leads to the automatic reboot at
shutdown on some machines. It turned out that the fix for one side
triggers another BIOS bug in other side. So, it's exclusive.
Since the original S5 wakeups have been confirmed only on HP machines,
it'd be safer to apply it only to limited machines. As a wild guess,
limiting to machines with HP PCI SSID should suffice.
This patch should be backported to kernels as old as 3.12, that
contain the commit 638298dc66ea36623dbc2757a24fc2c4ab41b016 "xhci: Fix
spurious wakeups after S5 on Haswell".

The sun4i timer can still be ticking when we enable the interrupt.
If another timer is actually used (A7 architected timer, for example),
odds are that the interrupt will eventually fire with the event_handler
pointer being NULL.
The obvious fix it to stop the timer before registering the interrupt.

Apart from data-type specific alignment constraints, there are also
architecture-specific alignment requirements.
For example, on s390 symbols must be on even addresses implying a 2-byte
alignment. If the system_certificate_list_end symbol is on an odd address
and if this address is loaded, the least-significant bit is ignored. As a
result, the load_system_certificate_list() fails to load the certificates
because of a wrong certificate length calculation.
To be safe, align system_certificate_list on an 8-byte boundary. Also improve
the length calculation of the system_certificate_list content. Introduce a
system_certificate_list_size (8-byte aligned because of unsigned long) variable
that stores the length. Let the linker calculate this size by introducing
a start and end label for the certificate content.

Due to the cross dependencies between hwmod for automanaged device
information for OMAP and dts node definitions, we can run into scenarios
where the dts node is defined, however it's hwmod entry is yet to be
added. In these cases:
a) omap_device does not register a pm_domain (since it cannot find
hwmod entry).
b) driver does not know about (a), does a pm_runtime_get_sync which
never fails
c) It then tries to do some operation on the device (such as read the
revision register (as part of probe) without clock or adequate OMAP
generic PM operation performed for enabling the module.
This causes a crash such as that reported in:
https://bugzilla.kernel.org/show_bug.cgi?id=66441
When 'ti,hwmod' is provided in dt node, it is expected that the device
will not function without the OMAP's power automanagement. Hence, when
we hit a fail condition (due to hwmod entries not present or other
similar scenario), fail at pm_domain level due to lack of data, provide
enough information for it to be fixed, however, it allows for the driver
to take appropriate measures to prevent crash.

This loop in xfs_growfs_data_private() is incorrect for V4
superblocks filesystems:
for (bucket = 0; bucket < XFS_AGFL_SIZE(mp); bucket++)
agfl->agfl_bno[bucket] = cpu_to_be32(NULLAGBLOCK);
For V4 filesystems, we don't have a agfl header structure, and so
XFS_AGFL_SIZE() returns an entire sector's worth of entries, which
we then index from an offset into the sector. Hence: buffer overrun.
This problem was introduced in 3.10 by commit 77c95bba ("xfs: add
CRC checks to the AGFL") which changed the AGFL structure but failed
to update the growfs code to handle the different structures.
Fix it by using the correct offset into the buffer for both V4 and
V5 filesystems.

For discard operation, we should return EINVAL if the given range length
is less than a block size, otherwise it will go through the file system
to discard data blocks as the end range might be evaluated to -1, e.g,
# fstrim -v -o 0 -l 100 /xfs7
/xfs7: 9811378176 bytes were trimmed
This issue can be triggered via xfstests/generic/288.
Also, it seems to get the request queue pointer via bdev_get_queue()
instead of the hard code pointer dereference is not a bad thing.

If we allocate less than sizeof(struct attrlist) then we end up

snd_pcm_uframes_t is defined as unsigned long so it would take
different sizes depending on 32 or 64bit architectures. As we don't
want this ABI incompatibility, and there is no real 64bit user yet,
let's make it the fixed size with __u32.
Also bump the protocol version number to 0.1.2.

When running a 32bit kernel the hda_intel driver is still reporting
a 64bit dma_mask if the HW supports it.
From sound/pci/hda/hda_intel.c:
/* allow 64bit DMA address if supported by H/W */
if ((gcap & ICH6_GCAP_64OK) && !pci_set_dma_mask(pci, DMA_BIT_MASK(64)))
pci_set_consistent_dma_mask(pci, DMA_BIT_MASK(64));
else {
pci_set_dma_mask(pci, DMA_BIT_MASK(32));
pci_set_consistent_dma_mask(pci, DMA_BIT_MASK(32));
}
which means when there is a call to dma_alloc_coherent from
snd_malloc_dev_pages a machine address bigger than 32bit can be returned.
This can be true in particular if running the 32bit kernel as a pv dom0
under the Xen Hypervisor or PAE on bare metal.
The problem is that when calling setup_bdle to program the BLE the
dma_addr_t returned from the dma_alloc_coherent is wrongly truncated
from snd_sgbuf_get_addr if running a 32bit kernel:
static inline dma_addr_t snd_sgbuf_get_addr(struct snd_dma_buffer *dmab,
size_t offset)
{
struct snd_sg_buf *sgbuf = dmab->private_data;
dma_addr_t addr = sgbuf->table[offset >> PAGE_SHIFT].addr;
addr &= PAGE_MASK;
return addr + offset % PAGE_SIZE;
}
where PAGE_MASK in a 32bit kernel is zeroing the upper 32bit af addr.
Without this patch the HW will fetch the 32bit truncated address,
which is not the one obtained from dma_alloc_coherent and will result
to a non working audio but can corrupt host memory at a random location.
The current patch apply to v3.13-rc3-74-g6c843f5

git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks into timers/core
Pull posix cpu timer changes for v3.14 from Frederic Weisbecker:
* Remove dying thread/process timers caching that was complicating the code
for no significant win.
* Remove early task reference release on dying timer sample read. Again it was
not worth the code complication. The other timer's resources aren't released
until timer_delete() is called anyway (or when the whole process dies).
* Remove leftover arguments in reaped target cleanup
* Consolidate some timer sampling code
* Remove use of tasklist lock
* Robustify sighand locking against exec and exit by using the safer
lock_task_sighand() API instead of sighand raw locking.
* Convert some unnecessary BUG_ON() to WARN_ON()

This fixes a kernel panic when resuming from suspend to RAM.
Without this fix an interrupt hits after the delayed work is canceled

boot option is used
The SGI UV tlb shootdown code panics the system with a NULL
pointer deference if 'nobau' is specified on the boot
commandline.
uv_flush_tlb_other() gets called for every flush, whether the
BAU is disabled or not. It should not be keeping the s_enters
statistic while the BAU is disabled.
The panic occurs because during initialization
init_per_cpu_tunables() does not set the bcp->statp pointer if
'nobau' was specified.
