First, I finally figured out this is not really important for me. |
15 |
"Supported Processor types" is ONLY for 32 bits. One or more of those |
16 |
need to be set ONLY if the kernel needs to run on a 32 bit system. |
17 |
That is why it would be set for any live image which will run on 32 |
18 |
bits, but would all be off for any distro that no longer supports 32 |
19 |
bits. |

Using menuconfig does not truncate .config. However, my current guess |
22 |
is that some combination of settings where "Supported processor types" |
23 |
(CONFIG_PROCESSOR_SELECT) IS selected and perhaps one of it's sub |
24 |
settings (CONFIG_CPU XXX) is NOT selected causes make xconfig or |
25 |
gconfig to completely reset the configuration, reducing the next saved |
26 |
version to under 10k. |

I found a (not much used) linux-config mailing list, and I'll probably |
29 |
post the issue there. |
