20# ecpu_check
21# Usage:
22#
23# ecpu_check array_of_cpu_flags
24#
25# array_of_cpu_flags - An array of cpu flags to check against USE flags
26#
27# Checks user USE related cpu flags against /proc/cpuinfo. If user enables a
28# cpu flag that is not supported in their processor flags, it will warn the
29# user if CROSSCOMPILE is not set to 1 ( because cross compile users are
30# obviously using different cpu flags than their own cpu ). Examples:
31#
32# CPU_FLAGS=(mmx mmx2 sse sse2)
33# ecpu_check CPU_FLAGS

1064# Usage: unpack_pdv [file to unpack] [size of off_t]

1067# the size of the off_t type (in bytes) on the machine that built the pdv
1068# archive. one way to determine this is by running the following commands:
1069# strings <pdv archive> | grep lseek
1070# strace -elseek <pdv archive>
1071# basically look for the first lseek command (we do the strings/grep because
1072# sometimes the function call is _llseek or something) and steal the 2nd
1073# parameter. here is an example:
1074# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1075# lseek
1076# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1077# lseek(3, -4, SEEK_END) = 2981250
1078# thus we would pass in the value of '4' as the second parameter.
