修改源码路径：kernel/scripts/mkcompile_h

#!/bin/sh
TARGET=$1
ARCH=$2
SMP=$3
PREEMPT=$4
CC=$5
vecho() { [ "${quiet}" = "silent_" ] || echo "$@" ; }
# If compile.h exists already and we don't own autoconf.h
# (i.e. we're not the same user who did make *config), don't
# modify compile.h
# So "sudo make install" won't change the "compiled by <user>"
# do "compiled by root"
if [ -r $TARGET -a ! -O include/generated/autoconf.h ]; then
  vecho "  SKIPPED $TARGET"
  exit 0
fi
# Do not expand names
set -f
# Fix the language to get consistent output
LC_ALL=C
export LC_ALL
if [ -z "$KBUILD_BUILD_VERSION" ]; then
if [ -r .version ]; then
  VERSION=`cat .version`
else
  VERSION=0
  echo 0 > .version
fi
else
VERSION=$KBUILD_BUILD_VERSION
fi
if [ -z "$KBUILD_BUILD_TIMESTAMP" ]; then
TIMESTAMP=`date`
else
TIMESTAMP=$KBUILD_BUILD_TIMESTAMP
fi
if test -z "$KBUILD_BUILD_USER"; then
LINUX_COMPILE_BY=$(whoami | sed 's/\\/\\\\/')
else
LINUX_COMPILE_BY=$KBUILD_BUILD_USER
fi
LINUX_COMPILE_BY="builder"
if test -z "$KBUILD_BUILD_HOST"; then
LINUX_COMPILE_HOST=`hostname`
else
LINUX_COMPILE_HOST=$KBUILD_BUILD_HOST
fi
LINUX_COMPILE_HOST="buildMachine"
UTS_VERSION="#$VERSION"
CONFIG_FLAGS=""
if [ -n "$SMP" ] ; then CONFIG_FLAGS="SMP"; fi
if [ -n "$PREEMPT" ] ; then CONFIG_FLAGS="$CONFIG_FLAGS PREEMPT"; fi
UTS_VERSION="$UTS_VERSION $CONFIG_FLAGS $TIMESTAMP"
# Truncate to maximum length
UTS_LEN=64
UTS_TRUNCATE="cut -b -$UTS_LEN"
# Generate a temporary compile.h
( echo /\* This file is auto generated, version $VERSION \*/
  if [ -n "$CONFIG_FLAGS" ] ; then echo "/* $CONFIG_FLAGS */"; fi

  echo \#define UTS_MACHINE \"$ARCH\"
  echo \#define UTS_VERSION \"`echo $UTS_VERSION | $UTS_TRUNCATE`\"
  echo \#define LINUX_COMPILE_BY \"`echo $LINUX_COMPILE_BY | $UTS_TRUNCATE`\"
  echo \#define LINUX_COMPILE_HOST \"`echo $LINUX_COMPILE_HOST | $UTS_TRUNCATE`\"
  echo \#define LINUX_COMPILER \"`$CC -v 2>&1 | tail -n 1`\"
) > .tmpcompile
if [ -r $TARGET ] && \
   grep -v 'UTS_VERSION' $TARGET > .tmpver.1 && \
   grep -v 'UTS_VERSION' .tmpcompile > .tmpver.2 && \
   cmp -s .tmpver.1 .tmpver.2; then
rm -f .tmpcompile
else
vecho "  UPD    $TARGET"
mv -f .tmpcompile $TARGET
fi

rm -f .tmpver.1 .tmpver.2

修改红色 LINUX_COMPILE_BY，LINUX_COMPILE_HOST 宏为自己想改的信息

其实改kernel\init\version.c 这2个宏。。会提示 kernel version unavailable。
