Subject: [PATCH] uml: fix debug output on x86_64
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=621009f4baf24581211dbb7b0816e01ed9fa8496;p=linux-beck.git

[PATCH] uml: fix debug output on x86_64

The debug-stub patch was broken on x86_64 because it thinks the frame size
there is 168 words.  In reality, it is 168 bytes, and using HOST_FRAME_SIZE,
which is expressed in consistent units across architectures, fixes this.
