There are cases where full date information is required instead of
just the year. Add month and day parsing to dmi_get_year() and rename
it to dmi_get_date().As the original function only required '/' followed by any number of
parseable characters at the end of the string, keep that behavior to
avoid upsetting existing users.The new function takes dates of format [mm[/dd]]/yy[yy]. Year, month
and date are checked to be in the ranges of [1-9999], [1-12] and
[1-31] respectively and any invalid or out-of-range component is
returned as zero.The dummy implementation is updated accordingly but the return value
is updated to indicate field not found which is consistent with how
other dummy functions behave.Signed-off-by: Tejun Heo

Year parsing in dmi_get_year() had the following two bugs.
* "00" is treated as invalid instead of 2000 because zero return from
simple_strtoul() is treated as error.* "0N" where N >= 8 is treated as invalid of 200N because the leading
0 is considered to specify octal.Fix the above two bugs by using endptr to detect invalid number and
forcing decimal.Signed-off-by: Tejun Heo

It is generally agreed that it would be beneficial for u64 to be an
unsigned long long on all architectures. ia64 (in common with several
other 64-bit architectures) currently uses unsigned long. Migrating
piecemeal is too painful; this giant patch fixes all compilation warnings
and errors that come as a result of switching to use int-ll64.h.Note that userspace will still see __u64 defined as unsigned long. This
is important as it affects C++ name mangling.[Updated by Tony Luck to change efi.h:efi_freemem_callback_t to use
u64 for start/end rather than unsigned long]Signed-off-by: Matthew Wilcox

Addresses http://bugzilla.kernel.org/show_bug.cgi?id=13484
Peer reported:
| The bug is introduced from kernel 2.6.27, if E820 table reserve the memory
| above 4G in 32bit OS(BIOS-e820: 00000000fff80000 - 0000000120000000
| (reserved)), system will report Int 6 error and hang up. The bug is caused by
| the following code in drivers/firmware/memmap.c, the resource_size_t is 32bit
| variable in 32bit OS, the BUG_ON() will be invoked to result in the Int 6
| error. I try the latest 32bit Ubuntu and Fedora distributions, all hit this
| bug.
|======
|static int firmware_map_add_entry(resource_size_t start, resource_size_t end,
| const char *type,
| struct firmware_map_entry *entry)and it only happen with CONFIG_PHYS_ADDR_T_64BIT is not set.
it turns out we need to pass u64 instead of resource_size_t for that.

Community reported one SB600 SATA issue(BZ #9412), which led to 64 bit
DMA disablement for all SB600 revisions by driver maintainers with
commits c7a42156d99bcea7f8173ba7a6034bbaa2ecb77c and
4cde32fc4b32e96a99063af3183acdfd54c563f0.But the root cause is ASUS M2A-VM system BIOS bug in old revisions
like 0901, while forcing into 32bit DMA happens to work as workaround.
Now it's time to withdraw 4cde32fc4b32e96a99063af3183acdfd54c563f0
so as to restore the SB600 SATA 64bit DMA capability.
This patch is also adding the workaround for M2A-VM old BIOS revisions,
but users are suggested to upgrade their system BIOS to the latest one
if they meet this issue.Signed-off-by: Shane Huang

Some notebooks from HP have the problem that their BIOSes attempt to
spin down hard drives before entering ACPI system states S4 and S5.
This leads to a yo-yo effect during system power-off shutdown and the
last phase of hibernation when the disk is first spun down by the
kernel and then almost immediately turned on and off by the BIOS.
This, in turn, may result in shortening the disk's life times.To prevent this from happening we can blacklist the affected systems
using DMI information. However, only the on-board controlles should
be blacklisted and their PCI slot numbers can be used for this
purpose. Unfortunately the existing interface for checking DMI
information of the system is not very convenient for this purpose,
because to use it, we would have to define special callback functions
or create a separate struct dmi_system_id table for each blacklisted
system.To overcome this difficulty introduce a new function
dmi_first_match() returning a pointer to the first entry in an array
of struct dmi_system_id elements that matches the system DMI
information. Then, we can use this pointer to access the entry's
.driver_data field containing the additional information, such as
the PCI slot number, allowing us to do the desired blacklisting.Signed-off-by: Rafael J. Wysocki

Impact: Should permit VMware detection on older platforms where the
vendor is changed. Could theoretically cause a regression if some
weird serial number scheme contains the string "VMware" by pure
chance. Seems unlikely, especially with the mixed case.In some user configured cases, VMware may choose not to put a VMware specific
DMI string, but the product serial key is always there and is VMware specific.

information.Signed-off-by: Alok N Kataria

The iscsi_ibft.c changes are almost certainly a bugfix as the
pointer 'ip' is a u8 *, so they never print the last 8 bytes
of the IPv6 address, and the eight bytes they do print have
a zero byte with them in each 16-bit word.Other than that, this should cause no difference in functionality.

Tejun's commit 7b595756ec1f49e0049a9e01a1298d53a7faaa15 made sysfs
attribute->owner unnecessary. But the field was left in the structure to
ease the merge. It's been over a year since that change and it is now
time to start killing attribute->owner along with its users - one arch at
a time!This patch is attempt #1 to get rid of attribute->owner only for
CONFIG_X86_64 or CONFIG_X86_32 . We will deal with other arches later on
as and when possible - avr32 will be the next since that is something I
can test. Compile (make allyesconfig / make allmodconfig / custom config)
and boot tested.akpm: the idea is that we put the declaration of sttribute.owner inside
`#ifndef CONFIG_X86'. But that proved to be too ambitious for now because
new usages kept on turning up in subsystem trees.[akpm: remove the ifdef for now]

I got this patch through Red Hat's bugzilla from the bug submitter and
patch creator. I have just fixed it up so it applies without fuzz to
upstream kernels.Original patch and description from Shyam kumar Iyer:
The issue [ibft module not displaying targets with short names] is because
of an offset calculatation error in the iscsi_ibft.c code. Due to this
error directory structure for the target in /sys/firmware/ibft does not
get created and so the initiator is unable to connect to the target.Note that this bug surfaced only with an name that had a short section at
the end. eg: "iqn.1984-05.com.dell:dell". It did not surface when the
iqn's had a longer section at the end. eg:
"iqn.2001-04.com.example:storage.disk2.sys1.xyz"So, the eot_offset was calculated such that an extra 48 bytes i.e. the
size of the ibft_header which has already been accounted was subtracted
twice.This was not evident with longer iqn names because they would overshoot
the total ibft length more than 48 bytes and thus would escape the bug.Signed-off-by: Shyam Kumar Iyer
