2005-09-12[PATCH] x86-64: Use physflat on Intel for < 8 CPUs with CPU hotplugAndi Kleen
This avoids races with the APIC broadcast/mask modes. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-09-12[PATCH] x86-64: Improve error handling for overlapping PXMs in SRAT.Andi Kleen
- Report PXMs instead of nodes - Report the correct PXM, not always the one of node 1. - Only warn for the case of a PXM overlapping by itself Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-09-12[PATCH] x86-64: Remove freeing of SMP trampoline pagesAndi Kleen
Nick points out it never worked because PageReserved was set and it might cause problems later on. Also HOTPLUG_CPU is much more common now so let's care not too much about the !hotplug case.

2005-09-12[PATCH] x86-64: Fix show_mem a little bitAndi Kleen

2005-09-12[PATCH] x86-64: Remove disable_tsc code in context switchAndi Kleen
It only offers extremly dubious security advantages and is not worth the overhead in this critical path. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-09-12[PATCH] x86-64: Fix (harmless) typo in head.S early level2 page tableAndi Kleen
The global bit was not set in the first 2MB page, instead it had a bit in the free AVL section which is useless. Fixed thus. Noticed by Eric Biederman Cc: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-09-12[PATCH] x86-64: Fix idle=pollHugh Dickins
x86_64 idle=poll might be a little less responsive than it should: unlike mwait_idle, and unlike i386, its poll_idle left TIF_POLLING_NRFLAG set. Signed-off-by: Hugh Dickins <hugh@veritas.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-09-12[PATCH] x86-64: Add simnow consoleAndi Kleen
This adds console and earlyprintk support for a host file on AMD's SimNow simulator. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-09-12[PATCH] x86-64: Make remote TLB flush more scalableAndi Kleen
Instead of using a global spinlock to protect the state of the remote TLB flush use a lock and state for each sending CPU. To tell the receiver where to look for the state use 8 different call vectors. Each CPU uses a specific vector to trigger flushes on other CPUs. Depending on the received vector the target CPUs look into the right per cpu variable for the flush data. When the system has more than 8 CPUs they are hashed to the 8 available vectors. The limited global vector space forces us to this right now. In future when interrupts are split into per CPU domains this could be fixed, at the cost of needing more IPIs in flat mode. Also some minor cleanup in the smp flush code and remove some outdated debug code. Requires patch to move cpu_possible_map setup earlier.

2005-09-12[PATCH] x86-64: Fix 32bit sendfileTsuneo.Yoshioka@f-secure.com
If we use 64bit kernel on ia64/x86_64/s390 architecture, and we run 32bit binary on 32bit compatibility mode, sendfile system call seems be not set offset argument. This is because sendfile's return value is not zero but the code regards the result by return value is zero or not. This problem will be affect to ia64/x86_64/s390 and not affect to other architecture does not affect other architecture (mips/parisc/ppc64/sparc64).

2005-09-12[PATCH] x86-64: Remove code to resume machine check state of other CPUs.Andi Kleen

2005-09-12[PATCH] x86-64: Make lockless machine check record passing a bit more robust.Andi Kleen
One machine is constantly throwing NMI watchdog timeouts in mce_log This was one attempt to fix it. (AK: this doesn't actually fix the bug I'm seeing unfortunately, probably drop.

2005-09-12[PATCH] x86-64: Don't assume APIC for boot processor has an APIC ID of zeroAndi Kleen
Originally from Stuart Hayes. When setting up the APIC for the Uniprocessor kernel don't assume the CPU has an APIC ID of zero.

2005-09-12[PATCH] x86-64: Support dualcore and 8 socket systems in k8 fallback node ↵Andi Kleen
parsing In particular on systems where the local APIC space and node space is very different from the Linux CPU number space. Previously the older NUMA setup code directly parsing the K8 northbridge registers had some issues on 8 socket or dual core systems. This patch fixes them. This is mainly done by fixing some confusion between Linux CPU numbers and local APIC ids. We now pass the local APIC IDs to later code, which avoids mismatches. Also add some heuristics to detect cases where the Hypertransport nodeids and the local APIC IDs don't match, but are shifted by a constant offset. This is still all quite hackish, hopefully BIOS writers fill in correct SRATs instead. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-09-12[PATCH] x86-64: Don't assign CPU numbers in SRAT parsingAndi Kleen

2005-09-12[PATCH] x86-64: Enable interrupts during delay calibration on APsAndi Kleen
