There's a fairly obvious infinite loop in there. Also, use roundup_pow_of_two() rather than open-coding stuff. Cc: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by:

Handle memory-mapped chips properly, needed for example on DECstations. This support was in Linux 2.4 but for some reason got lost in 2.6. This patch is taken directly from the linux-mips repository. [akpm@osdl.org: cleanup] Signed-off-by:

Newer ARMs have a 40 bit physical address space, but mapping physical memory above 4G needs a special page table format which we (currently?) do not use for userspace mappings, so what happens instead is that mapping an address >= 4G will happily discard the upper bits and wrap. There is a valid_mmap_phys_addr_range() arch hook where we could check for >= 4G addresses and deny the mapping, but this hook takes an unsigned long address: static inline int valid_mmap_phys_addr_range(unsigned long addr, size_t size); And drivers/char/mem.c:mmap_mem() calls it like this: static int mmap_mem(struct file * file, struct vm_area_struct * vma) { size_t size = vma->vm_end - vma->vm_start; if (!valid_mmap_phys_addr_range(vma->vm_pgoff << PAGE_SHIFT, size)) So that's not much help either. This patch makes the hook take a pfn instead of a phys address.

When EDAC was first introduced into the kernel it had a sysfs interface, but due to some problems it was disabled in 2.6.16 and remained disabled in 2.6.17. With feedback, several of the control and attribute files of that interface had some good constructive feedback. PCI Blacklist/Whitelist was a major set which has design issues and it has been removed in this patch. Instead of storing PCI broken parity status in EDAC, it has been moved to the pci_dev structure itself by a previous PCI patch. A future patch will enable that feature in EDAC by utilizing the pci_dev info. The sysfs is now enabled in this patch, with a minimal set of control and attribute files for examining EDAC state and for enabling/disabling the memory and PCI operations. The Documentation for EDAC has also been updated to reflect the new state of EDAC operation. Signed-off-by:

-
Jeff Dike authored
This fixes an exitcall ordering bug - calls to ignore_sigio_fd can come from exitcalls that come after the sigio thread has been killed. This would cause shutdown to hang or crash. Fixed by having ignore_sigio_fd check that the thread is present before trying to communicate with it. Signed-off-by:

os_isatty can be made to disappear by moving maybe_sigio_broken from kernel to user code. This also lets write_sigio_workaround become static. Signed-off-by:

When UML is built as a static binary, it segfaults when run. The reason is that a memory hole that is present in dynamic binaries isn't there in static binaries, and it contains essential stuff. This fix removes the code which maps some anonymous memory into that hole and cleans up some related code. Signed-off-by:

This cleans up the mess that is the timer initialization. There used to be two timer handlers - one that basically ran during delay loop calibration and one that handled the timer afterwards. There were also two sets of timer initialization code - one that starts in user code and calls into the kernel side of the house, and one that starts in kernel code and calls user code. This eliminates one timer handler and consolidates the two sets of initialization code. [akpm@osdl.org: use new INTF_ flags] Signed-off-by:

I was looking at the code of the UML and more precisely at the functions set_task_sizes_tt and set_task_sizes_skas. I noticed that these 2 functions take a paramater (arg) which is not used : the function is always called with the value 0. I suppose that this value might change in the future (or even can be configured), so I added a constant in mem_user.h file. Also, I rounded CONFIG_HOST_TASk_SIZE to a 4M. Signed-off-by:

swsusp should not use memcpy for snapshotting memory, because on some architectures memcpy may increase preempt_count (i386 does this when CONFIG_X86_USE_3DNOW is set). Then, as a result, wrong value of preempt_count is stored in the image. Replace memcpy in copy_data_pages with an open-coded loop. Signed-off-by:

Matthew Wilcox notified me that CONFIG_PM_STD_PARTITION="/dev/hda2" in the i386 defconfig wasn't a good idea (especially since it prevented booting for him due to another bug). This patch sets CONFIG_PM_STD_PARTITION="" in the i386 defconfig. Signed-off-by:
