linux-toradex.git/arch/parisc/include/asm/shmparam.h, branch v4.10 Linux kernel for Apalis and Colibri modules parisc: change value of SHMLBA from 0x00400000 to PAGE_SIZE 2014-04-13T13:00:53+00:00 Helge Deller deller@gmx.de 2014-04-09T17:49:28+00:00 0ef36bd2b37815719e31a72d2beecc28ca8ecd26 On parisc, SHMLBA was defined to 0x00400000 (4MB) to reflect that we need to take care of our caches for shared mappings. But actually, we can map a file at any multiple address of PAGE_SIZE, so let us correct that now with a value of PAGE_SIZE for SHMLBA. Instead we now take care of this cache colouring via the constant SHM_COLOUR while we map shared pages.
