Subjecthppa vDSO and compiler (non-)support
Hi,

since the "parisc: Add vDSO support" commit, I can no longer cross-build
a hppa kernel. I see two issues:

1) CROSS32_COMPILE detection doesn't work here, as openSUSE provides
hppa-suse-linux-* binaries. It's easy to overcome by
"CROSS32_COMPILE=hppa-suse-linux-"

2) openSUSE doesn't provide any libc for hppa. So gcc doesn't provide
libgcc.a and the build of vDSO fails.

So could vDSO be optional on hppa via KConfig?

I used to use the cross compiler to at least compile-check the following
tty drivers:
arch/parisc/kernel/pdc_cons.o
drivers/tty/serial/mux.o
drivers/tty/serial/8250/8250_gsc.o

thanks,
