Currently a SIGTRAP can denote any one of below reasons. - Breakpoint hit - H/W debug register hit - Single step - Signal sent through kill() or rasie() Architectures like powerpc/parisc provides infrastructure to demultiplex SIGTRAP signal by passing down the information for receiving SIGTRAP through si_code of siginfot_t structure. Here is an attempt is generalise this infrastructure by extending it to x86 and x86_64 archs.

While updating the rcu code, I noticed that do_nmi() for AVR32 is odd: There is an nmi_enter() call without an nmi_exit().

On AVR32, all parameters beyond the 5th are passed on the stack. System calls don't use the stack -- they borrow a callee-saved register instead. This means that syscalls that take 6 parameters must be called through a stub that pushes the last parameter on the stack. This patch adds a stub for sync_file_range syscall on AVR32 architecture.

Commit deac93df ("lib: Correct printk %pF to work on all architectures") broke the non modular builds by moving an essential function into modules.c. Fix this by moving it out again and into asm/sections.h as an inline. To do this, the definition of struct ppc64_opd_entry has been lifted out of modules.c and put in asm/elf.h where it belongs.

One of the changes in the bootwrapper makefile introduced the dtbImage targets for boards that need a simple zImage with a DTB embedded in them (595be948, "[POWERPC] bootwrapper: Build multiple cuImages"). When this was done, it broke booting on the Holly board as the zImage.holly wrapper did not get the DTB embedded properly. This changes the target for the Holly board to a dtbImage so that the wrapper includes the vmlinux, wrapper bits, and DTB.

For Freescale 8xxx devices that use an MPIC, the interrupt numbers in the device tree must be 16 greater than the values documented in the reference manual. In these chips, the MPIC is wired to use the first 16 numbers for external interrupts, but the documentation numbers internal interrupts from 0. In the MPC8610 HPCD device tree, the interrupt properties for the DMA channels for DMA2 were not the adjusted values. This fixes that.

Based upon a report by Meelis Roos. Any function call can try to access the current thread register via the _mcount hooks when the kernel is built with -pg (via ftrace or STACK_DEBUG). That can't be setup properly very early on during the bootup of other cpus for sun4u and some early sun4v systems. So add notrace markers to these specific functions, so that _mcount doesn't get invoked too early. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Certainly, if we support such processors, then we should start with _PAGE_NX initially clear in __supported_pte_flags, and then set it once we've established that the processor does indeed support NX. That will prevent early_ioremap - or anything else - from trying to set it. The simple fix is to simply call check_efer() earlier.
