2014-07-27serial: 8250_dw: Add support for deferred probingChen-Yu Tsai1-7/+34
The 8250_dw driver fails to probe if the specified clock isn't registered at probe time. Even if a clock frequency is given, the required clock might be gated because it wasn't properly enabled. This happened to me when the device is registered through DT, and the clock was part of an MFD, the PRCM found on A31 and A23 SoCs. Unlike core clocks that are registered with OF_CLK_DECLARE, which happen almost immediately after the kernel starts, the clocks are registered as sub-devices of the PRCM MFD platform device. Even though devices are registered in the order they are found in the DT, the drivers are registered in a different, arbitrary order. It is possible that the 8250_dw driver is registered, and thus associated with the device and probed, before the clock driver is registered and probed. 8250_dw then reports unable to get the clock, and fails. Without a working console, the kernel panics. This patch adds support for deferred probe handling for the clock and reset controller. It also fixes the cleanup path if serial8250_register_8250_port fails. Signed-off-by: Chen-Yu Tsai <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>

2014-07-27serial: st-asc: Fix overflow in baudrate calculationMaxime COQUELIN1-5/+5
In the current calculation, if the required baud rate is above 262143, we get an overflow. This patch uses a 64bits variable to do the maths. Also, we remove the '+1' to avoid a divide by zero if the input clock rate is something unexpected. Indeed, if the input clock rate is zero, it is preferable to be notified, since the UART won't work anyway.

2014-07-27serial: st-asc: Don't call BUG in asc_console_setup()Maxime COQUELIN1-1/+2
In order to prevent an asc instance to be used as early console, BUG_ON is used on either mapbase or membase being NULL. Problem is that this condition is also true when we set console to be a ttyASx different to the first asc instance being probed. Instead of calling BUG_ON, it now returns -ENXIO when either mapbase or membase is NULL. Signed-off-by: Maxime Coquelin <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>

2014-07-26Fix gcc-4.9.0 miscompilation of load_balance() in schedulerLinus Torvalds1-0/+2
Michel Dänzer and a couple of other people reported inexplicable random oopses in the scheduler, and the cause turns out to be gcc mis-compiling the load_balance() function when debugging is enabled. The gcc bug apparently goes back to gcc-4.5, but slight optimization changes means that it now showed up as a problem in 4.9.0 and 4.9.1. The instruction scheduling problem causes gcc to schedule a spill operation to before the stack frame has been created, which in turn can corrupt the spilled value if an interrupt comes in. There may be other effects of this bug too, but that's the code generation problem seen in Michel's case. This is fixed in current gcc HEAD, but the workaround as suggested by Markus Trippelsdorf is pretty simple: use -fno-var-tracking-assignments when compiling the kernel, which disables the gcc code that causes the problem. This can result in slightly worse debug information for variable accesses, but that is infinitely preferable to actual code generation problems. Doing this unconditionally (not just for CONFIG_DEBUG_INFO) also allows non-debug builds to verify that the debug build would be identical: we can do export GCC_COMPARE_DEBUG=1 to make gcc internally verify that the result of the build is independent of the "-g" flag (it will make the compiler build everything twice, toggling the debug flag, and compare the results). Without the "-fno-var-tracking-assignments" option, the build would fail (even with 4.8.3 that didn't show the actual stack frame bug) with a gcc compare failure.
