Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
* 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: (185 commits) powerpc: fix compile error with 85xx/p1010rdb.c powerpc: fix compile error with 85xx/p1023_rds.c powerpc/fsl: add MSI support for the Freescale hypervisor arch/powerpc/sysdev/fsl_rmu.c: introduce missing kfree powerpc/fsl: Add support for Integrated Flash Controller powerpc/fsl: update compatiable on fsl 16550 uart nodes powerpc/85xx: fix PCI and localbus properties in p1022ds.dts powerpc/85xx: re-enable ePAPR byte channel driver in corenet32_smp_defconfig powerpc/fsl: Update defconfigs to enable some standard FSL HW features powerpc: Add TBI PHY node to first MDIO bus sbc834x: put full compat string in board match check powerpc/fsl-pci: Allow 64-bit PCIe devices to DMA to any memory address powerpc: Fix unpaired probe_hcall_entry and probe_hcall_exit offb: Fix setting of the pseudo-palette for >8bpp offb: Add palette hack for qemu "standard vga" framebuffer offb: Fix bug in calculating requested vram size powerpc/boot: Change the WARN to INFO for boot wrapper overlap message powerpc/44x: Fix build error on currituck platform powerpc/boot: Change the load address for the wrapper to fit the kernel powerpc/44x: Enable CRASH_DUMP for 440x ... Fix up a trivial conflict in arch/powerpc/include/asm/cputime.h due to the additional sparse-checking code for cputime_t.

* determine MEMORY_START until then. However we can determine PHYSICAL_START
* from information at hand (program counter, TLB lookup).
*
+ * On BookE with RELOCATABLE (RELOCATABLE_PPC32)
+ *
+ * With RELOCATABLE_PPC32, we support loading the kernel at any physical
+ * address without any restriction on the page alignment.
+ *
+ * We find the runtime address of _stext and relocate ourselves based on
+ * the following calculation:
+ *
+ * virtual_base = ALIGN_DOWN(KERNELBASE,256M) +
+ * MODULO(_stext.run,256M)
+ * and create the following mapping:
+ *
+ * ALIGN_DOWN(_stext.run,256M) => ALIGN_DOWN(KERNELBASE,256M)
+ *
+ * When we process relocations, we cannot depend on the
+ * existing equation for the __va()/__pa() translations:
+ *
+ * __va(x) = (x) - PHYSICAL_START + KERNELBASE
+ *
+ * Where:
+ * PHYSICAL_START = kernstart_addr = Physical address of _stext
+ * KERNELBASE = Compiled virtual address of _stext.
+ *
+ * This formula holds true iff, kernel load address is TLB page aligned.
+ *
+ * In our case, we need to also account for the shift in the kernel Virtual
+ * address.
+ *
+ * E.g.,
+ *
+ * Let the kernel be loaded at 64MB and KERNELBASE be 0xc0000000 (same as PAGE_OFFSET).
+ * In this case, we would be mapping 0 to 0xc0000000, and kernstart_addr = 64M
+ *
+ * Now __va(1MB) = (0x100000) - (0x4000000) + 0xc0000000
+ * = 0xbc100000 , which is wrong.
+ *
+ * Rather, it should be : 0xc0000000 + 0x100000 = 0xc0100000
+ * according to our mapping.
+ *
+ * Hence we use the following formula to get the translations right:
+ *
+ * __va(x) = (x) - [ PHYSICAL_START - Effective KERNELBASE ]
+ *
+ * Where :
+ * PHYSICAL_START = dynamic load address.(kernstart_addr variable)
+ * Effective KERNELBASE = virtual_base =
+ * = ALIGN_DOWN(KERNELBASE,256M) +
+ * MODULO(PHYSICAL_START,256M)
+ *
+ * To make the cost of __va() / __pa() more light weight, we introduce
+ * a new variable virt_phys_offset, which will hold :
+ *
+ * virt_phys_offset = Effective KERNELBASE - PHYSICAL_START
+ * = ALIGN_DOWN(KERNELBASE,256M) -
