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.

2011-07-21x86: Make Dell Latitude E5420 use reboot=pciDaniel J Blueman
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. Unfortunately that turned out to be incorrect. ] Signed-off-by: Daniel J Blueman <daniel.blueman@gmail.com> Link: http://lkml.kernel.org/r/1305248699-2347-1-git-send-email-daniel.blueman@gmail.com Signed-off-by: H.

copy_from_user_nmi() is used in oprofile and perf. Moving it to other library functions like copy_from_user(). As this is x86 code for 32 and 64 bits, create a new file usercopy.c for unified code.

2011-07-21x86: Serialize EFI time accesses on rtc_lockJan Beulich
The EFI specification requires that callers of the time related runtime functions serialize with other CMOS accesses in the kernel, as the EFI time functions may choose to also use the legacy CMOS RTC. Besides fixing a latent bug, this is a prerequisite to safely enable the rtc-efi driver for x86, which ought to be preferred over rtc-cmos on all EFI platforms.

2011-07-21x86: Serialize SMP bootup CMOS accesses on rtc_lockJan Beulich
With CPU hotplug, there is a theoretical race between other CMOS (namely RTC) accesses and those done in the SMP secondary processor bringup path. I am unware of the problem having been noticed by anyone in practice, but it would very likely be rather spurious and very hard to reproduce. So to be on the safe side, acquire rtc_lock around those accesses.

2011-07-21x86: Fix write lock scalability 64-bit issueJan Beulich
With the write lock path simply subtracting RW_LOCK_BIAS there is, on large systems, the theoretical possibility of overflowing the 32-bit value that was used so far (namely if 128 or more CPUs manage to do the subtraction, but don't get to do the inverse addition in the failure path quickly enough). A first measure is to modify RW_LOCK_BIAS itself - with the new value chosen, it is good for up to 2048 CPUs each allowed to nest over 2048 times on the read path without causing an issue. Quite possibly it would even be sufficient to adjust the bias a little further, assuming that allowing for significantly less nesting would suffice. However, as the original value chosen allowed for even more nesting levels, to support more than 2048 CPUs (possible currently only for 64-bit kernels) the lock itself gets widened to 64 bits.
