Vivek Goyal	983d5dbdb2	[PATCH] x86_64: Fix SMP bootup with CONFIG_KDUMP enabled o This fix was posted for i386 long back. Posting it for x86_64. http://marc.theaimsgroup.com/?l=linux-kernel&m=110380103229830&w=2 o This patch fixes the problem of secondary cpus boot up. This situation is faced when kernel is built for default locations like 16MB and onwards. In this configuration, only primary cpu (BP) comes and secondary cpus don't boot. o Problem occurs because in trampoline code, lgdt is not able to load the GDT as it happens to be situated beyond 16MB. This is due to the fact that cpu is still in real mode and default operand size is 16bit. o This patch uses lgdtl instead of lgdt to force operand size to 32 instead of 16.

Linus Torvalds	1da177e4c3	Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
