2011-07-22lguest: use a special 1:1 linear pagetable mode until first switch.Rusty Russell3-9/+12
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 Evans7-1/+1106
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.

Rebooting on the Dell E5420 often hangs with the keyboard or ACPI methods, but is reliable via the PCI method. [ hpa: this was deferred because we believed for a long time that the recent reshuffling of the boot priorities in commit 660e34cebf0a11d54f2d5dd8838607452355f321 fixed this platform.

2011-07-12arm: davinci: Fix low level gpio irq handlers' argumentIdo Yariv1-5/+16
Commit 7416401 ("arm: davinci: Fix fallout from generic irq chip conversion") introduced a bug, causing low level interrupt handlers to get a bogus irq number as an argument. The gpio irq handler falsely assumes that the handler data is the irq base number and that is no longer true. Set the irq handler data to be a pointer to the corresponding gpio controller. The chained irq handler can then use it to extract both the irq base number and the gpio registers structure.

2011-07-12powerpc/mm: Fix memory_block_size_bytes() for non-pseriesBenjamin Herrenschmidt1-11/+19
Just compiling pseries in the kernel causes it to override memory_block_size_bytes() regardless of what is the runtime platform. This cleans up the implementation of that function, fixing a bug or two while at it, so that it's harmless (and potentially useful) for other platforms. Without this, bugs in that code would trigger a WARN_ON() in drivers/base/memory.c when booting some different platforms. If/when we have another platform supporting memory hotplug we might want to either move that out to a generic place or make it a ppc_md. callback.
