2009-05-11x86: add extension fields for bootloader type and versionH. Peter Anvin
A long ago, in days of yore, it all began with a god named Thor. There were vikings and boats and some plans for a Linux kernel header. Unfortunately, a single 8-bit field was used for bootloader type and version. This has generally worked without *too* much pain, but we're getting close to flat running out of ID fields. Add extension fields for both type and version. The type will be extended if it the old field is 0xE; the version is a simple MSB extension. Keep /proc/sys/kernel/bootloader_type containing (type << 4) + (ver & 0xf) for backwards compatiblity, but also add /proc/sys/kernel/bootloader_version which contains the full version number.

2008-12-16x86: documentation fix regarding boot protocolPhilipp Kohlbecher
Impact: clarify documentation Documentation/x86/boot.txt describes payload_offset as the offset from the end of the real-mode code. In fact, it is more accurately described as the offset from the beginning of the protected-mode code, as (a) this is how it is actually calculated and (b) the padding after the real-mode code is not included in the offset.
