Subject: Preparing for KA60 support, crank IPL_TTY to level 0x16 (since it is
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=b5a17663768cd9f20c2832d7a005d3eb81879e4f;p=openbsd

Preparing for KA60 support, crank IPL_TTY to level 0x16 (since it is
hardwired this way on KA60...), and compensate in splassert_check() when
serial device interrupts will remain at 0x14 or 0x15.
