2007-11-29PNP: increase the maximum number of resourcesZhao Yakui
On some systems the number of resources(IO,MEM) returnedy by PNP device is greater than the PNP constant, for example motherboard devices. It brings that some resources can't be reserved and resource confilicts. This will cause PCI resources are assigned wrongly in some systems, and cause hang. This is a regression since we deleted ACPI motherboard driver and use PNP system driver.

2007-11-29xen: mask _PAGE_PCD from ptesJeremy Fitzhardinge
_PAGE_PCD maps a page with caching disabled, which is typically used for mapping harware registers. Xen never allows it to be set on a mapping, and unprivileged guests never need it since they can't see the real underlying hardware. However, some uncached mappings are made early when probing the (non-existent) APIC, and its OK to mask off the PCD flag in these cases. This became necessary because Xen started checking for this bit, rather than silently masking it off.

2007-11-29Fix boot problem with iSeries lacking hugepage supportMel Gorman
Ordinarily the size of a pageblock is determined at compile-time based on the hugepage size. On PPC64, the hugepage size is determined at runtime based on what is supported by the machine. With legacy machines such as iSeries that do not support hugepages, HPAGE_SHIFT is 0. This results in pageblock_order being set to -PAGE_SHIFT and a crash results shortly afterwards. This patch adds a function to select a sensible value for pageblock order by default when HUGETLB_PAGE_SIZE_VARIABLE is set. It checks that HPAGE_SHIFT is a sensible value before using the hugepage size; if it is not MAX_ORDER-1 is used. This is a fix for 2.6.24. Credit goes to Stephen Rothwell for identifying the bug and testing candidate patches. Additional credit goes to Andy Whitcroft for spotting a problem with respects to IA-64 before releasing. Additional credit to David Gibson for testing with the libhugetlbfs test suite.

2007-11-29update checkpatch.pl to version 0.12Andy Whitcroft
This version brings a new terse output mode as well as many improvements to the unary detection and bare type regcognition. It also brings the usual updates for false positives, though these seem to be slowing markedly now that the unary detector is no longer just putting its finger in the air and guessing. Of note: - new --terse mode producing a single line per report - loosening of the block brace checks - new checks for enum/union/struch brace placements - hugely expanded "bare type" detection - checks for inline usage - better handling of already open comment blocks - handle patches which introduce or remove lines without newlines Andy Whitcroft (19): Version: 0.12 style fixes as spotted by checkpatch add a --terse options of a single line of output per report block brace checks should only apply for single line blocks all new bare type detector check spacing for open braces with enum, union and struct check for LINUX_VERSION_CODE macros definition bracketing checks need to ignore -ve context clean up the mail-back mode, -q et al expand possible type matching to declarations allow const and sparse annotations on possible types handle possible types as regular types everywhere prefer plain inline over __inline__ and __inline all new open comment detection fix up conditional extraction for if assignment checks add const to the possible type matcher unary checks: a for loop is a conditional too possible types: detect function pointer definitions handle missind newlines at end of file, report addition Signed-off-by: Andy Whitcroft <apw@shadowen.org> Acked-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-11-28USB: uevent environment key fixAlan Stern
This patch (as1010) was written by both Kay Sievers and me. It solves the problem of duplicated keys in USB uevent structures by refactoring the uevent subroutines, taking advantage of the way the hotplug core calls uevent handlers for the device's bus and for the device's type. Keys needed for both USB-device and USB-interface events are added in usb_uevent(), which is the bus handler. Keys appropriate only for USB-device or USB-interface events are added in usb_dev_uevent() or usb_if_uevent() respectively, the type handlers. In addition, unnecessary tests for NULL pointers are removed as are duplicated debugging log statements.

I found that there is a off-by-one problem in the following code. Version: 2.6.24-rc2 File: fs/sysfs/file.c:118-122 Function: fill_read_buffer -------------------------------------------------------------------- count = ops->show(kobj, attr_sd->s_attr.attr, buffer->page); sysfs_put_active_two(attr_sd); BUG_ON(count > (ssize_t)PAGE_SIZE); -------------------------------------------------------------------- Because according to the specification of the sysfs and the implement of the show methods, the show methods return the number of bytes which would be generated for the given input, excluding the trailing null.So if the return value of the show methods equals PAGE_SIZE - 1, the buffer is full in fact. And if the return value equals PAGE_SIZE, the resulting string was already truncated,or buffer overflow occurred. This patch fixes an off-by-one error in fill_read_buffer.
