[8u] [RFR] Request for Review of Backport of JDK-8197429: Increased stack guard causes segfaults on x86-32

[Andrew Hughes]

[CCing hotspot list for review]

Bug: https://bugs.openjdk.java.net/browse/JDK-8197429
Webrev: http://cr.openjdk.java.net/~andrew/openjdk8/8197429/webrev.01/
Original review thread:
http://mail.openjdk.java.net/pipermail/hotspot-dev/2018-February/030076.html

The code patch is largely the same, with the only
difference that 8 still uses StackYellowPages
and StackRedPages rather than the
JavaThread::stack_red_zone_size() and
JavaThread::stack_yellow_zone_size() functions.

The test differs in that the 8u version needs to
also compile the C code within the test.
I based this on test/runtime/InitialThreadOverflow.

Thanks,
