Subject: [parisc-linux] explicitly allocate executable pages?
Date: Fri, 16 Jan 2004 22:58:50 -0700 [thread overview]
Message-ID: <20040117055850.GA28550@colo.lackof.org> (raw)
Could someone explain the following code in arch/parisc/mm/init.c?

thanks,
grant

#if !defined(CONFIG_STI_CONSOLE)
#warning STI console should explicitly allocate executable pages but does not
/*

if (address >= ro_start && address < ro_end
&& address != fv_addr
&& address != gw_addr)
pte = __mk_pte(address, PAGE_KERNEL_RO);
else
#endif
