RH-Commit: [1/23] c33a2769b041e62285eb7840f8a7c05ac32aca7b (thuth/qemu-kvm-cs9)
|
|
|
|
We are going to link the SLOF libc into the s390-ccw.img, and this
|
|
libc needs more memory for providing space for malloc() and friends.
|
|
Thus bump the memory size that we reserve for the bios to 3 MiB
|
|
instead of only 2 MiB. While we're at it, add a proper check that
|
|
there is really enough memory assigned to the machine before blindly
|
|
using it.
|
