* linux: Fix warnings.Justus Winter2017-10-261-2/+1
| | | | * linux/dev/glue/net.c (device_write): Remove unused variables.
* linux: Fix interrupt glue.Justus Winter2017-09-301-2/+16
| | | | | | | | | | | Previously, we used an invalid pointer to mark interrupts as reserved by Mach. This, however, crashes code trying to iterate over the list of interrupt handlers. Use a valid structure instead. * linux/dev/arch/i386/kernel/irq.c (reserved_mach_handler): New function. (reserved_mach): New variable. (reserve_mach_irqs): Use the new variable.
* linux: Remove incompatible local prototype.Justus Winter2016-10-121-4/+3
| | | | | * linux/dev/glue/kmem.c (vremap): Remove prototype, include the right header instead.

| | | | | | | | | | * kern/assert.h (Assert): Add function argument. (assert): Supply function argument. * kern/debug.c (Assert): Add function argument. Unify message format. (panic): Rename to 'Panic', add location information. * kern/debug.h (panic): Rename, and add a macro version that supplies the location. * linux/dev/include/linux/kernel.h: Use the new panic macro.

* Update Linux block layer glue codeRichard Braun2016-09-211-15/+16
| | | | | | | | | | The Linux block layer glue code needs to use page nodes with the appropriate interface since their redefinition as struct list. * linux/dev/glue/block.c: Include <kern/list.h>.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of a "page considered external", which apparently takes into account whether a page is dirty or not, redefine this property to reliably mean "is in an external object". This commit mostly deals with the impact of this change on the page allocation interface. * i386/intel/pmap.c (pmap_page_table_page_alloc): Update call to vm_page_grab. * kern/slab.c (kmem_pagealloc_physmem): Use vm_page_grab instead of vm_page_grab_contig.
