ia64 ioremap is now smart enough to use the correct memory attributes, so remove the EFI checks from osl.c. Signed-off-by:

Here's a patch that fixes EFI boot for x86 on 2.6.16-rc5-mm3. The off-by-one is admittedly my fault, but the other two fix up the rest.

Almost all users of the table addresses from the EFI system table want physical addresses. So rather than doing the pa->va->pa conversion, just keep physical addresses in struct efi. This fixes a DMI bug: the efi structure contained the physical SMBIOS address on x86 but the virtual address on ia64, so dmi_scan_machine() used ioremap() on a virtual address on ia64. This is essentially the same as an earlier patch by Matt Tolentino: http://marc.theaimsgroup.com/?l=linux-kernel&m=112130292316281&w=2 except that this changes all table addresses, not just ACPI addresses. Matt's original patch was backed out because it caused MCAs on HP sx1000 systems. That problem is resolved by the ioremap() attribute checking added for ia64. Signed-off-by:

Bjorn Helgaas authored
dmi_scan_machine() tries to ioremap 0x10000 (64K) bytes, even though it only looks at the first 32 bytes or so. If the SMBIOS table is near the end of a memory region, the ioremap() may fail when it shouldn't. This is in the efi_enabled path, so it really only affects ia64 at the moment. Signed-off-by:

Check the EFI memory map so we can use the correct memory attributes for ioremap(). Previously, we always used uncacheable access, which blows up on some machines for regular system memory. Signed-off-by:

Pass the size, not a pointer to the size, to efi_mem_attribute_range(). This function validates memory regions for the /dev/mem read/write/mmap paths. The pointer allows arches to reduce the size of the range, but I think that's unnecessary complexity. Simplifying it will let me use efi_mem_attribute_range() to improve the ia64 ioremap() implementation. Signed-off-by:

Enable DMI table parsing on ia64. Andi Kleen has a patch in his x86_64 tree which enables the use of i386 dmi_scan.c on x86_64. dmi_scan.c functions are being used by the drivers/char/ipmi/ipmi_si_intf.c driver for autodetecting the ports or memory spaces where the IPMI controllers may be found. This patch adds equivalent changes for ia64 as to what is in the x86_64 tree. In addition, I reworked the DMI detection, such that on EFI-capable systems, it uses the efi.smbios pointer to find the table, rather than brute-force searching from 0xF0000. On non-EFI systems, it continues the brute-force search. My test system, an Intel S870BN4 'Tiger4', aka Dell PowerEdge 7250, with latest BIOS, does not list the IPMI controller in the ACPI namespace, nor does it have an ACPI SPMI table. Also note, currently shipping Dell x8xx EM64T servers don't have these either, so DMI is the only method for obtaining the address of the IPMI controller. Signed-off-by:

Currently /proc/iomem exports physical memory also apart from io device memory. But on i386, it truncates any memory more than 4GB. This leads to problems for kexec/kdump. Kexec reads /proc/iomem to determine the system memory layout and prepares a memory map based on that and passes it to the kernel being kexeced. Given the fact that memory more than 4GB has been truncated, new kernel never gets to see and use that memory. Kdump also reads /proc/iomem to determine the physical memory layout of the system and encodes this informaiton in ELF headers. After a crash new kernel parses these ELF headers being used by previous kernel and vmcore is prepared accordingly. As memory more than 4GB has been truncated, kdump never sees that memory and never prepares ELF headers for it. Hence vmcore is truncated and limited to 4GB even if there is more physical memory in the system. This patch exports memory more than 4GB through /proc/iomem on i386. Signed-off-by:

We have a problem in a lot of emulated storage in that it takes a page from get_user_pages() and does something like kmap_atomic(page) modify page kunmap_atomic(page) However, nothing has flushed the kernel cache view of the page before the kunmap. We need a lightweight API to do this, so this new API would specifically be for flushing the kernel cache view of a user page which the kernel has modified. The driver would need to add flush_kernel_dcache_page(page) before the final kunmap. Signed-off-by:

Currently, get_user_pages() returns fully coherent pages to the kernel for anything other than anonymous pages. This is a problem for things like fuse and the SCSI generic ioctl SG_IO which can potentially wish to do DMA to anonymous pages passed in by users. The fix is to add a new memory management API: flush_anon_page() which is used in get_user_pages() to make anonymous pages coherent. Signed-off-by:

It has been discovered that the remove_proc_entry has a race in the removing of entries in the proc file system that are siblings. There's no protection around the traversing and removing of elements that belong in the same subdirectory. This subdirectory list is protected in other areas by the BKL. So the BKL was at first used to protect this area too, but unfortunately, remove_proc_entry may be called with spinlocks held. The BKL may schedule, so this was not a solution. The final solution was to add a new global spin lock to protect this list, called proc_subdir_lock. This lock now protects the list in remove_proc_entry, and I also went around looking for other areas that this list is modified and added this protection there too. Care must be taken since these locations call several functions that may also schedule. Since I don't see any location that these functions that modify the subdirectory list are called by interrupts, the irqsave/restore versions of the spin lock was _not_ used. Signed-off-by:
