S6E63D6 is initialised in the boot-loader, so we only have to take care of the LCD. EET also adds several buttons and LEDs on GPIOs. This patch adds a "pcm037_variant=" kernel command line parameter to specify at boot-time which board the kernel is running on, default is "pcm970", specify "eet" for the EET board.

Maintainers for: alpha, ia64 and m68k, please have a look, your arch code is funny. The header magic is a bit odd, but similar to the KERNEL_DS one, CPP waits with expanding these macros until the INIT_THREAD_INFO macro itself is expanded, which is in arch/*/kernel/init_task.c where we've already included sched.h so we're good.

808347f6a31792079e345ec865e9cfcb6e8ae6b2 Mon Sep 17 00:00:00 2001 From: Nicolas Ferre Date: Wed, 22 Jul 2009 20:04:45 +0200 Subject: dmaengine: at_hdmac: add DMA slave transfers This patch for at_hdmac adds the slave transfers capability to the Atmel DMA controller available on some AT91 SOCs. This allow peripheral to memory and memory to peripheral transfers with hardware handshaking. Slave structure for controller specific information is passed through channel private data. This at_dma_slave structure is defined in at_hdmac.h header file and relative hardware definition are moved to this file from at_hdmac_regs.h. Doing this we allow the channel configuration from platform definition code. This work is intensively based on dw_dmac and several slave implementations.

Basically, the TLB can be loaded with "large" pages that cover the whole virtual space (well, sort-of, half of it actually) represented by a PTE page, and which contain an "indirect" bit indicating that this TLB entry RPN points to an array of PTEs from which the TLB can then create direct entries. Thus, in order to invalidate those when PTE pages are deleted, we need the virtual address to pass to tlbilx or tlbivax instructions. The old trick of sticking it somewhere in the PTE page struct page sucks too much, the address is almost readily available in all call sites and almost everybody implemets these as macros, so we may as well add the argument everywhere. I added it to the pmd and pud variants for consistency.
