2011-07-22OpenRISC: System callsJonas Bonn
The OpenRISC Linux kernel conforms to the "generic" syscall interface which contains only the reduced set of syscalls deemed necessary for new architectures. Unfortunately, the uClibc port for OpenRISC does not fully support this reduced set; as such, an additional patch available out-of-tree needs to be applied to the kernel in order to use the current uClibc. This is just a temporary measure until the libc port can be straightened out; it is likely that OpenRISC will make the transition to glibc shortly where the generic syscall interface is better supported.

2011-07-22OpenRISC: PTraceJonas Bonn
This patch implements minimal PTrace support. The pt_regs structure is not exported to userspace for OpenRISC; rather, the GETREGSET mechanism is intended to be used and the registers, as such, exported in the core dump format which is ABI stable. This is in line with what is intended for new architectures as of 2.6.34 and has the advantage of permitting the layout of the registers on the kernel stack (as per pt_regs) to be freely modified.

2011-07-22asm-generic: move archictures to common delay.hJonas Bonn
This patch moves the in-tree architectures that were using the 'generic' delay.h over to using the header file in asm-generic. This is not done using the generic-y mechanism as none of these arch's have started using that mechanism yet. This is a trivial change to make later when the arch begins using generic-y. Note the subtle change to the avr32 and SH architectures where the argument to __const_udelay was previously using the rounded down constant value instead of the rounded up value.

2011-07-22lguest: use a special 1:1 linear pagetable mode until first switch.Rusty Russell
The Host used to create some page tables for the Guest to use at the top of Guest memory; it would then tell the Guest where this was. In particular, it created linear mappings for 0 and 0xC0000000 addresses because lguest used to switch to its real page tables quite late in boot. However, since d50d8fe19 Linux initialized boot page tables in head_32.S even before the "are we lguest?" boot jump. So, now we can simplify things: the Host pagetable code assumes 1:1 linear mapping until it first calls the LHCALL_NEW_PGTABLE hypercall, which we now do before we reach C code. This also means that the Host doesn't need to know anything about the Guest's PAGE_OFFSET. (Non-Linux guests might not even have such a thing). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2011-07-21net: filter: BPF 'JIT' compiler for PPC64Matt Evans
An implementation of a code generator for BPF programs to speed up packet filtering on PPC64, inspired by Eric Dumazet's x86-64 version. Filter code is generated as an ABI-compliant function in module_alloc()'d mem with stackframe & prologue/epilogue generated if required (simple filters don't need anything more than an li/blr). The filter's local variables, M[], live in registers. Supports all BPF opcodes, although "complicated" loads from negative packet offsets (e.g. SKF_LL_OFF) are not yet supported. There are a couple of further optimisations left for future work; many-pass assembly with branch-reach reduction and a register allocator to push M[] variables into volatile registers would improve the code quality further. This currently supports big-endian 64-bit PowerPC only (but is fairly simple to port to PPC32 or LE!). Enabled in the same way as x86-64: echo 1 > /proc/sys/net/core/bpf_jit_enable Or, enabled with extra debug output: echo 2 > /proc/sys/net/core/bpf_jit_enable Signed-off-by: Matt Evans <matt@ozlabs.org> Acked-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.
