2013-09-30arm64: include VIRTIO_{MMIO,BLK} in defconfigRamkumar Ramachandra
Currently, development on arm64 is aided by a Foundation_v8 emulator distributed by ARM [1]. To run their kernels, users will execute: $ ./Foundation_v8 --image linux-system.axf --block-device raring-rootfs To mount the raring-rootfs filesystem, the kernel parameter should typically include: root=/dev/vda For this device to be present, the kernel must be compiled with VIRTIO_{MMIO,BLK}. To make this work out-of-the-box, make it part of the default configuration.

2013-09-30tile: use a more conservative __my_cpu_offset in CONFIG_PREEMPTChris Metcalf
It turns out the kernel relies on barrier() to force a reload of the percpu offset value. Since we can't easily modify the definition of barrier() to include "tp" as an output register, we instead provide a definition of __my_cpu_offset as extended assembly that includes a fake stack read to hazard against barrier(), forcing gcc to know that it must reread "tp" and recompute anything based on "tp" after a barrier. This fixes observed hangs in the slub allocator when we are looping on a percpu cmpxchg_double. A similar fix for ARMv7 was made in June in change 509eb76ebf97.

In the flexcan_chip_start() function first the flexcan core is going through the soft reset sequence, then the RX FIFO is enabled. With the hardware is put into FIFO mode, message buffers 1...7 are reserved by the FIFO engine. The remaining message buffers are in reset default values.

2013-09-30s390: Allow vmalloc target buffers for copy_from_oldmem()Michael Holzheu
Currently copy_from_oldmem() is not able to copy to virtual memory. When using kexec pre-allocated ELF header, copy_from_oldmem() is used to copy the ELF notes information to vmalloc buffers.
