2013-05-10docs: minor: fix mentioning of Documentation/Daniel Borkmann1-1/+1
The Documentation/ folder no longer exists. Either everything important can be found in the man pages or other documentation files. Fix the mentioning of Documentation/. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-04-11docs: move some of them to the root directoryDaniel Borkmann1-0/+833
Lets move CodingStyle, SubmittingPatches, and Sponsors into the root directory of netsniff-ng and remove the Documentation folder. Some of those files are quite bloated, and most of these things should be in the man-pages anyway. They should be the only big sources of documentation, nothing else. The rest is currently put here: http://pub.netsniff-ng.org/docs/ Signed-off-by: Daniel Borkmann <dborkman@redhat.com>

x86/efi: Always map the first physical page into the EFI pagetables
Commit: 129766708 ("x86/efi: Only map RAM into EFI page tables if in mixed-mode") stopped creating 1:1 mappings for all RAM, when running in native 64-bit mode. It turns out though that there are 64-bit EFI implementations in the wild (this particular problem has been reported on a Lenovo Yoga 710-11IKB), which still make use of the first physical page for their own private use, even though they explicitly mark it EFI_CONVENTIONAL_MEMORY in the memory map. In case there is no mapping for this particular frame in the EFI pagetables, as soon as firmware tries to make use of it, a triple fault occurs and the system reboots (in case of the Yoga 710-11IKB this is very early during bootup). Fix that by always mapping the first page of physical memory into the EFI pagetables. We're free to hand this page to the BIOS, as trim_bios_range() will reserve the first page and isolate it away from memory allocators anyway. Note that just reverting 129766708 alone is not enough on v4.9-rc1+ to fix the regression on affected hardware, as this commit: ab72a27da ("x86/efi: Consolidate region mapping logic") later made the first physical frame not to be mapped anyway.
