commit 74142ffc0b upstream.
The regmap used by max77686 MFD driver was not freed with regmap_exit()
on driver exit. This lead to leak of resources.
Replace regmap_init_i2c() call in driver probe with initialization of
managed register map so the regmap will be properly freed by the device
management code.

commit ad85ace07a upstream.
Currently, if we use perf kvm --guestkallsyms --guestmodules report, we
can not get the perf information from perf data file. All sample are
shown as unknown.
Reproducing steps:
# perf kvm --guestkallsyms /tmp/kallsyms --guestmodules /tmp/modules record -a sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.624 MB perf.data.guest (~27260 samples) ]
# perf kvm --guestkallsyms /tmp/kallsyms --guestmodules /tmp/modules report |grep %
100.00% [guest/6471] [unknown] [g] 0xffffffff8164f330
This bug was introduced by 207b57926 (perf kvm: Fix regression with guest machine creation).
In original code, it uses perf_session__find_machine(), it means we deliver symbol to machine
which has the same pid, if no machine found, deliver it to *default* guest. But if we use
perf_session__findnew_machine() here, if no machine was found, new machine with pid will be built
and added. Then the default guest which with pid == 0 will never get a symbol.
And because the new machine initialized here has no kernel map created, the symbol delivered to
it will be marked as "unknown".
This patch here is to revert commit 207b57926 and fix the SEGFAULT bug in another way.
Verification steps:
# ./perf kvm --guestkallsyms /home/kallsyms --guestmodules /home/modules record -a sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.651 MB perf.data.guest (~28437 samples) ]

commit 75ea799df4 upstream.
The current MAX8907 driver has two issues related to weekday value
handling:
1)
The HW WEEKDAY register has range 0..6 rather than 1..7 as documented.
Note that I validated the actual HW range by observing the HW register
roll from 6->0 rather than 6->7->1 as would otherwise be expected.
This matches Linux's tm_wday range of 0..6.
When the CMOS RAM content is lost, the date returned from the device is
2007-01-01 00:00:00, which is a Monday. The WEEKDAY register reads 1 in
this case. This matches the numbering in Linux's tm_wday field.
Hence we should write Linux's tm_wday value to the register without
modifying it. Hence, remove the +1/-1 calculations for WEEKDAY/tm_wday.
2)
There's no need to make alarms match on the WEEKDAY register, since the
other fields together uniquely define the alarm date/time. Ignoring the
WEEKDAY value in the match isolates the driver from any incorrect value in
the current time copy of the WEEKDAY register.
Each change individually, or both together, solves an issue that I
observed; "hwclock -r" would time out waiting for its alarm to fire if the
CMOS RAM content had been lost, and hence the WEEKDAY register value
mismatched what the driver expected it to be. "hwclock -w" would solve
this by over-writing the HW default WEEKDAY register value with what the
driver expected.

commit d6a484520c upstream.
In commit 85747f ("PATCH] parport: add NetMOS 9805 support") Max added
the PCI ID for NetMOS 9805 based on a Debian bug report from 2k4 which
was at the v2.4.26 time frame. The patch made into 2.6.14.
Shortly before that patch akpm merged commit 296d3c783b ("[PATCH] Support
NetMOS based PCI cards providing serial and parallel ports") which made
into v2.6.9-rc1.
Now we have two different entries for the same PCI id.
I have here the NetMos 9805 which claims to support SPP/EPP/ECP mode.
This patch takes Max's entry for titan_1284p1 (base != -1 specifies the
ioport for ECP mode) and replaces akpm's entry for netmos_9805 which
specified -1 (=none). Both share the same PCI-ID (my card has subsystem
0x1000 / 0x0020 so it should match PCI_ANY).
While here I also drop the entry for titan_1284p2 which is the same as
netmos_9815.

commit 3685f19e07 upstream.
Tegra chips have 4 or 5 identical UART modules embedded. UARTs C..E have
their MODEM-control signals tied off to a static state. However UARTs A
and B can optionally route those signals to/from package pins, depending
on the exact pinmux configuration.
When these signals are not routed to package pins, false interrupts may
trigger either temporarily, or permanently, all while not showing up in
the IIR; it will read as NO_INT. This will eventually lead to the UART
IRQ being disabled due to unhandled interrupts. When this happens, the
kernel may print e.g.:
irq 68: nobody cared (try booting with the "irqpoll" option)
In order to prevent this, enable UART_BUG_NOMSR. This prevents
UART_IER_MSI from being enabled, which prevents the false interrupts
from triggering.
In practice, this is not needed under any of the following conditions:
* On Tegra chips after Tegra30, since the HW bug has apparently been
fixed.
* On UARTs C..E since their MODEM control signals are tied to the correct
static state which doesn't trigger the issue.
* On UARTs A..B if the MODEM control signals are routed out to package
pins, since they will then carry valid signals.
However, we ignore these exceptions for now, since they are only relevant
if a board actually hooks up more than a 4-wire UART, and no currently
supported board does this. If we ever support a board that does, we can
refine the algorithm that enables UART_BUG_NOMSR to take those exceptions
into account, and/or read a flag from DT/... that indicates that the
board has hooked up and pinmux'd more than a 4-wire UART.

One problem is that recursively_mark_NOTATTACHED() uses the intfdata
value and hub->hdev->maxchild while hub_disconnect() is clearing them.
Another problem is that it uses hub->ports[i] while the port device is
being released.
To fix this race, we need to hold the device_state_lock while
hub_disconnect() changes the values. (Note that usb_disconnect()
and hub_port_connect_change() already acquire this lock at similar
critical times during a USB device's life cycle.) We also need to
remove the port devices after maxchild has been set to 0, instead of
before.

for instance, by using the TCSETS2-interface to repeatedly request

The x32 case for the recvmsg() timout handling is broken:
asmlinkage long compat_sys_recvmmsg(int fd, struct compat_mmsghdr __user *mmsg,
unsigned int vlen, unsigned int flags,
struct compat_timespec __user *timeout)
{
int datagrams;
struct timespec ktspec;
if (flags & MSG_CMSG_COMPAT)
return -EINVAL;
if (COMPAT_USE_64BIT_TIME)
return __sys_recvmmsg(fd, (struct mmsghdr __user *)mmsg, vlen,
flags | MSG_CMSG_COMPAT,
(struct timespec *) timeout);
...
The timeout pointer parameter is provided by userland (hence the __user
annotation) but for x32 syscalls it's simply cast to a kernel pointer
and is passed to __sys_recvmmsg which will eventually directly
dereference it for both reading and writing. Other callers to
__sys_recvmmsg properly copy from userland to the kernel first.
The bug was introduced by commit ee4fa23c4b ("compat: Use
COMPAT_USE_64BIT_TIME in net/compat.c") and should affect all kernels
since 3.4 (and perhaps vendor kernels if they backported x32 support
along with this code).
Note that CONFIG_X86_X32_ABI gets enabled at build time and only if
CONFIG_X86_X32 is enabled and ld can build x32 executables.
Other uses of COMPAT_USE_64BIT_TIME seem fine.

commit 9e6c3b6339 upstream.
This patch is to fix a compiler warning of __bad_udelay due to a value
of >999 being passed as a parameter to udelay() in the function
e1000e_phy_has_link_generic(). This affects the gcc compiler when
it is given a flag of -O3 and the icc compiler.
This patch is also making the change from mdelay() to msleep() in the
same function, since it was determined though code inspection that this
function is never called in atomic context.
