USB: serial drivers need to use larger bulk-in buffers

When a driver doesn't know how much data a device is going to send,
the buffer size should be at least as big as the endpoint's maxpacket
value.  The serial drivers don't follow this rule; many of them
request only 256-byte bulk-in buffers.  As a result, they suffer
overflow errors if a high-speed device wants to send a lot of data,
because high-speed bulk endpoints are required to have a maxpacket
size of 512.

This patch (as1450) fixes the problem by using the driver's
bulk_in_size value as a minimum, always allocating buffers no smaller
than the endpoint's maxpacket size.

USB: isp1760: Implement solution for erratum 2

The document says:
|2.1 Problem description
|    When at least two USB devices are simultaneously running, it is observed that
|    sometimes the INT corresponding to one of the USB devices stops occurring. This may
|    be observed sometimes with USB-to-serial or USB-to-network devices.
|    The problem is not noticed when only USB mass storage devices are running.
|2.2 Implication
|    This issue is because of the clearing of the respective Done Map bit on reading the ATL
|    PTD Done Map register when an INT is generated by another PTD completion, but is not
|    found set on that read access. In this situation, the respective Done Map bit will remain
|    reset and no further INT will be asserted so the data transfer corresponding to that USB
|    device will stop.
|2.3 Workaround
|    An SOF INT can be used instead of an ATL INT with polling on Done bits. A time-out can
|    be implemented and if a certain Done bit is never set, verification of the PTD completion
|    can be done by reading PTD contents (valid bit).
|    This is a proven workaround implemented in software.

Russell King run into this with an USB-to-serial converter. This patch
implements his suggestion to enable the high frequent SOF interrupt only
at the time we have ATL packages queued. It goes even one step further
and enables the SOF interrupt only if we have more than one ATL packet
queued at the same time.

USB: s3c2410_udc: Add handling for S3C244X dual-packet mode

This is a patch that seems to make the USB hangs on the S3C244X go away.
At least a good amount of ping torture didn't make them come back so far.

The issue is that, if there are several back-to-back packets, sometimes no
interrupt is generated for one of them. This seems to be caused by the
mysterious dual packet mode, which the USB hardware enters automatically
if the endpoint size is half that of the FIFO. (On the 244X, this is the
normal situation for bulk data endpoints.)

There is also a timing factor in this. It seems that what happens is that
the USB hardware automatically sends an acknowledgement if there is only one
packet in the FIFO (the FIFO has space for two). If another packet arrives
before the host has retrieved and acknowledged the previous one, no interrupt
is generated for that second one.

However, there may be an indication. There is one undocumented bit (none
of the 244x manuals document it), OUT_CRS1_REG[1], that seems to be set
suspiciously often when this condition occurs. There is also
CLR_DATA_TOGGLE, OUT_CRS1_REG[7], which may have a function related to
this. (The Samsung manual is rather terse on that, as usual.)

This needs to be examined further. For now, the patch seems to do the
trick.

pci: use security_capable() when checking capablities during config space read

This reintroduces commit 47970b1b which was subsequently reverted
as f00eaeea.  The original change was broken and caused X startup
failures and generally made privileged processes incapable of reading
device dependent config space.  The normal capable() interface returns
true on success, but the LSM interface returns 0 on success.  This thinko
is now fixed in this patch, and has been confirmed to work properly.

So, once again...Eric Paris noted that commit de139a3 ("pci: check caps
from sysfs file open to read device dependent config space") caused the
capability check to bypass security modules and potentially auditing.
Rectify this by calling security_capable() when checking the open file's
capabilities for config space reads.

10 years agox86, ioapic: Don't warn about non-existing IOAPICs if we have none

x86, ioapic: Don't warn about non-existing IOAPICs if we have none

mp_find_ioapic() prints errors like:

    ERROR: Unable to locate IOAPIC for GSI 13

if it can't find the IOAPIC that manages that specific GSI. I
see errors like that at every boot of a laptop that apparently
doesn't have any IOAPICs.

But if there are no IOAPICs it doesn't seem to be an error that
none can be found. A solution that gets rid of this message is
to directly return if nr_ioapics (still) is zero. (But keep
returning -1 in that case, so nothing breaks from this change.)

The call chain that generates this error is:

pnpacpi_allocated_resource()
    case ACPI_RESOURCE_TYPE_IRQ:
        pnpacpi_parse_allocated_irqresource()
            acpi_get_override_irq()
                 mp_find_ioapic()

drm/radeon/kms: hopefully fix pll issues for real (v3)

The problematic boards have a recommended reference divider
to be used when spread spectrum is enabled on the laptop panel.
Enable the use of the recommended reference divider along with
the new pll algo.

v2: testing options

v3: When using the fixed reference divider with LVDS, prefer
min m to max p and use fractional feedback dividers.
