modpost: replace the use of NOFAIL() with xmalloc() etc.
I think x*alloc() functions are cleaner.

modpost: Optimize symbol search from linear to binary search
Modify modpost to use binary search for converting addresses back
into symbol references. Previously it used linear search.
This change
modpost: Optimize symbol search from linear to binary search
Modify modpost to use binary search for converting addresses back
into symbol references. Previously it used linear search.
This change saves a few seconds of wall time for defconfig builds,
but can save several minutes on allyesconfigs.
Before:
$ make LLVM=1 -j128 allyesconfig vmlinux -s KCFLAGS="-Wno-error"
$ time scripts/mod/modpost -M -m -a -N -o vmlinux.symvers vmlinux.o

After:
$ make LLVM=1 -j128 allyesconfig vmlinux -s KCFLAGS="-Wno-error"
$ time scripts/mod/modpost -M -m -a -N -o vmlinux.symvers vmlinux.o
