tree-wide: remove Emacs lines from all files This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.

shared: include what we use The next step of a general cleanup of our includes. This one mostly adds missing includes but there are a few removals as well.

tree-wide: sort includes in *.h This is a continuation of the previous include sort patch, which only sorted for .c files.

efivars: fix build for non-efi

shared: efivars - fix compile on non-EFI systems systemctl and logind were unconditionally using functions that were not compiled on non-EFI systems. Add stubs returning -EOPNOTSUPP to fix compile again.

shared: efivars - is_efi_*() returns bool instead of int There was a bug where is_efi_*() could return a negative error value, which would be treated as 'true', just make this a bool in the helper library to avoid the problem.

logind,systemctl: add reboot to EFI firmware support

remove unused includes This patch removes includes that are not used. The removals were found with include-what-you-use which checks if any of the symbols from a header is in use.

bootctl: add sd-boot support

support acpi firmware performance data (FPDT) Prefer firmware-provided performance data over loader-exported ones; if ACPI data is available, always use it, otherwise try to read the loader data. The firmware-provided variables start at the time the first EFI image is executed and end when the operating system exits the boot services; the (loader) time calculated in systemd-analyze increases.

bootctl: print secure boot flags

efi: various cleanups

bootctl: add boot loader and firmware interface tool

efi: add efi boot generator that automatically mounts the ESP to /boot

util: move is_efiboot() to efivars.c

core: if the bootloader supports it, determine firmware and boot loader delay This allows us to print simple performance data of all parts of the boot now: - firmware - boot loader - kernel - initrd - userspace This only works for bootloaders which support passing TSC data via EFI variables. As of now that's only gummiboot.
