uml: get rid of do_longjmp

2007-10-16T16:43:05Z

do_longjmp used to be needed when UML didn't have its own implementation of setjmp and longjmp. They came from libc, and couldn't be called directly from kernel code, as the libc jmp_buf couldn't be imported there. do_longjmp was a userspace function which served to provide longjmp access to kernel code. This is gone, and a number of void * pointers can now be jmp_buf *. Signed-off-by: Jeff Dike Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

uml: more __init annotations

2007-07-24T19:24:58Z

2.6.23-rc1 turned up another batch of references from non-__init code to __init code. In most cases, these were missing __init annotations. In one case (os_drop_memory), the annotation was present but wrong. init_maps is __init, but for some reason was being very careful about the mechanism by which it allocated memory, checking whether it was OK to use kmalloc (at this point in the boot, it definitely isn't) and using either alloc_bootmem_low_pages or kmalloc/vmalloc. So, the kmalloc/vmalloc code is removed. Signed-off-by: Jeff Dike Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

uml: add missing __init declarations

2007-05-07T19:13:01Z

The build started finding calls from non-init to init functions. These are just cases of init functions not being properly marked, so this patch fixes that. Signed-off-by: Jeff Dike Cc: Paolo 'Blaisorblade' Giarrusso Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

uml: remove user_util.h

2007-05-07T19:13:01Z

user_util.h isn't needed any more, so delete it and remove all includes of it. Signed-off-by: Jeff Dike Cc: Paolo 'Blaisorblade' Giarrusso Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

uml: create as-layout.h

2007-05-07T19:13:01Z

This patch moves all the the symbols defined in um_arch.c, which are mostly boundaries between different parts of the UML kernel address space, to a new header, as-layout.h. There are also a few things here which aren't really related to address space layout, but which don't really have a better place to go.

[PATCH] uml: fix LVM crash

2007-03-29T15:22:24Z

Permit lvm to create logical volumes without crashing UML. When device-mapper's DM_DEV_CREATE_CMD ioctl is called to create a new device, dev_create()->dm_create()->alloc_dev()-> blk_queue_bounce_limit(md->queue, BLK_BOUNCE_ANY) is called. blk_queue_bounce_limit(BLK_BOUNCE_ANY) calls init_emergency_isa_pool() if blk_max_pfn < blk_max_low_pfn. This is the case on UML, but init_emergency_isa_pool() hits BUG_ON(!isa_page_pool) because there doesn't seem to be a dma zone on UML for mempool_create() to allocate from. Most architectures seem to have max_low_pfn == max_pfn, but UML doesn't because of the uml_reserved chunk it keeps for itself. From what I can see, max_pfn and max_low_pfn don't get much use after the bootmem-allocator stops being used anyway, except that they initialize the block layer's blk_max_low_pfn/blk_max_pfn. This ensures init_emergency_isa_pool() doesn't crash uml in this situation by setting max_low_pfn == max_pfn in mem_init().
