Merge tag 'v4.4-rc2' into patchwork
Linux 4.4-rc2 Several PCI media drivers got broken on Kernel 4.4-rc1, due to pci_set_dma_mask() regressions. So, we need to add those fixes back for the media drivers to work again. * tag 'v4.4-rc2': (335 commits) Linux 4.4-rc2 slab/slub: adjust kmem_cache_alloc_bulk API slub: add missing kmem cgroup support to kmem_cache_free_bulk slub: fix kmem cgroup bug in kmem_cache_alloc_bulk slub: optimize bulk slowpath free by detached freelist slub: support for bulk free with SLUB freelists parisc: Map kernel text and data on huge pages parisc: Add Huge Page and HUGETLBFS support parisc: Use long branch to do_syscall_trace_exit parisc: Increase initial kernel mapping to 32MB on 64bit kernel parisc: Initialize the fault vector earlier in the boot process. parisc: Add defines for Huge page support parisc: Drop unused MADV_xxxK_PAGES flags from asm/mman.h serial: export fsl8250_handle_irq serial: 8250_mid: Add missing dependency tty: audit: Fix audit source serial: etraxfs-uart: Fix crash serial: fsl_lpuart: Fix earlycon support bcm63xx_uart: Use the device name when registering an interrupt tty: Fix direct use of tty buffer work ...
