multiple platforms Move declaration of struct pxa2xx_udc_mach_info from include/asm-arm/arch-pxa/udc.h to new file include/asm-arm/mach/udc_pxa2xx.h. This allow us to use this structure with multiple platforms - pxa and ixp4xx. USB device controller used in pxa25x is the same as controller used in ixp4xx.

2006-11-29[MTD] add get and put methodsArtem Bityutskiy
This patch adds get_device() and put_device() methods to the MTD description structure (struct mtd_info). These methods are called by MTD whenever the MTD device is get or put. They are needed when the underlying driver is something smarter then just flash chip driver, for example UBI. Signed-off-by: Artem Bityutskiy <dedekind@infradead.org>

2006-11-28[NET]: Fix MAX_HEADER setting.David S. Miller
MAX_HEADER is either set to LL_MAX_HEADER or LL_MAX_HEADER + 48, and this is controlled by a set of CONFIG_* ifdef tests. It is trying to use LL_MAX_HEADER + 48 when any of the tunnels are enabled which set hard_header_len like this: dev->hard_header_len = LL_MAX_HEADER + sizeof(struct xxx); The correct set of tunnel drivers which do this are: ipip ip_gre ip6_tunnel sit so make the ifdef test match.

2006-11-28[MTD] [NAND] remove len/ooblen confusion.Vitaly Wool
As was discussed between Ricard Wanderlöf, David Woodhouse, Artem Bityutskiy and me, the current API for reading/writing OOB is confusing. The thing that introduces confusion is the need to specify ops.len together with ops.ooblen for reads/writes that concern only OOB not data area. So, ops.len is overloaded: when ops.datbuf != NULL it serves to specify the length of the data read, and when ops.datbuf == NULL, it serves to specify the full OOB read length. The patch inlined below is the slightly updated version of the previous patch serving the same purpose, but with the new Artem's comments taken into account.

2006-11-26Fix 'ALIGN()' macro, take 2Linus Torvalds
You wouldn't think that doing an ALIGN() macro that aligns something up to a power-of-two boundary would be likely to have bugs, would you? But hey, in the wonderful world of mixing integer types, you have to be careful. This just makes sure that the alignment is interpreted in the same type as the thing to be aligned. Thanks to Roland Dreier, who noticed that the amso1100 driver got broken by the previous fix (that just extended the mask to "unsigned long", but was still broken in "unsigned long long" - it just happened to be the same on 64-bit architectures).

2006-11-25[PATCH] Enforce "unsigned long flags;" when spinlockingAlexey Dobriyan
Make it break or warn if you pass to spin_lock_irqsave() and friends something different from "unsigned long flags;". Suprisingly large amount of these was caught by recent commit c53421b18f205c5f97c604ae55c6a921f034b0f6 and others. Idea is largely from FRV typechecking. Suggestions from Andrew Morton. All stupid typos in first version fixed. Passes allmodconfig on i386, x86_64, alpha, arm as well as my usual config. Note #1: checking with sparse is still needed, because a driver can save and pass around flags or something. So far patch is very intrusive. Note #2: techically, we should break only if sizeof(flags) < sizeof(unsigned long), however, the more pain for getting suspicious code into kernel, the better.

2006-11-14[PATCH] hugetlb: prepare_hugepage_range check offset tooHugh Dickins
(David:) If hugetlbfs_file_mmap() returns a failure to do_mmap_pgoff() - for example, because the given file offset is not hugepage aligned - then do_mmap_pgoff will go to the unmap_and_free_vma backout path. But at this stage the vma hasn't been marked as hugepage, and the backout path will call unmap_region() on it. That will eventually call down to the non-hugepage version of unmap_page_range(). On ppc64, at least, that will cause serious problems if there are any existing hugepage pagetable entries in the vicinity - for example if there are any other hugepage mappings under the same PUD. unmap_page_range() will trigger a bad_pud() on the hugepage pud entries. I suspect this will also cause bad problems on ia64, though I don't have a machine to test it on. (Hugh:) prepare_hugepage_range() should check file offset alignment when it checks virtual address and length, to stop MAP_FIXED with a bad huge offset from unmapping before it fails further down. PowerPC should apply the same prepare_hugepage_range alignment checks as ia64 and all the others do. Then none of the alignment checks in hugetlbfs_file_mmap are required (nor is the check for too small a mapping); but even so, move up setting of VM_HUGETLB and add a comment to warn of what David Gibson discovered - if hugetlbfs_file_mmap fails before setting it, do_mmap_pgoff's unmap_region when unwinding from error will go the non-huge way, which may cause bad behaviour on architectures (powerpc and ia64) which segregate their huge mappings into a separate region of the address space.

2006-11-14[PATCH] x86-64: Fix race in exit_idleAndi Kleen
When another interrupt happens in exit_idle the exit idle notifier could be called an incorrect number of times. Add a test_and_clear_bit_pda and use it handle the bit atomically against interrupts to avoid this. Pointed out by Stephane Eranian Signed-off-by: Andi Kleen <ak@suse.de>
2006-11-14[PATCH] x86-64: Fix vgetcpu when CONFIG_HOTPLUG_CPU is disabledAndi Kleen
The vgetcpu per CPU initialization previously relied on CPU hotplug events for all CPUs to initialize the per CPU state. That only worked only on kernels with CONFIG_HOTPLUG_CPU enabled. On the others some CPUs didn't get their state initialized properly and vgetcpu wouldn't work. Change the initialization sequence to instead run in a normal initcall (which runs after the normal CPU bootup) and initialize all running CPUs there. Later hotplug CPUs are still handled with an hotplug notifier. This actually simplifies the code somewhat. Signed-off-by: Andi Kleen <ak@suse.de>
2006-11-14[PATCH] x86: Add acpi_user_timer_override option for Asus boardsAndi Kleen
Timer overrides are normally disabled on Nvidia board because they are commonly wrong, except on new ones with HPET support. Unfortunately there are quite some Asus boards around that don't have HPET, but need a timer override. We don't know yet how to handle this transparently, but at least add a command line option to force the timer override and let them boot.

2006-11-13[PATCH] Fix missing parens in set_personality()Russell King
If you call set_personality() with an expression such as: set_personality(foo ? PERS_FOO1 : PERS_FOO2); then this evaluates to: ((current->personality == foo ? PERS_FOO1 : PERS_FOO2) ? ... which is obviously not the intended result. Add the missing parents to ensure this gets evaluated as expected: ((current->personality == (foo ? PERS_FOO1 : PERS_FOO2)) ? ... Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-11-13[PATCH] mspec driver build fixJes Sorensen
Fix MSPEC driver to build for non SN2 enabled configs as the driver should work in cached and uncached modes (no fetchop) on these systems. In addition make MSPEC select IA64_UNCACHED_ALLOCATOR, which is required for it and move it to arch/ia64/Kconfig to avoid warnings on non ia64 architectures running allmodconfig. Once the Kconfig code is fixed, we can move it back.
