Andy Adamson 5842add2f3 [PATCH] VFS,fs/locks.c,NFSD4: add race_free posix_lock_file_conf() interface
Lockd and the NFSv4 server both exercise a race condition where
posix_test_lock() is called either before or after posix_lock_file() to
deal with a denied lock request due to a conflicting lock.

Remove the race condition for the NFSv4 server by adding a new conflicting
lock parameter to __posix_lock_file() , changing the name to
__posix_lock_file_conf().

Keep posix_lock_file() interface, add posix_lock_conf() interface, both
call __posix_lock_file_conf().

Eric Dumazet fa3536cc14 [PATCH] Use __read_mostly on some hot fs variables
I discovered on oprofile hunting on a SMP platform that dentry lookups were
slowed down because d_hash_mask, d_hash_shift and dentry_hashtable were in
a cache line that contained inodes_stat.  So each time inodes_stats is
changed by a cpu, other cpus have to refill their cache line.

This patch moves some variables to the __read_mostly section, in order to
avoid false sharing.  RCU dentry lookups can go full speed.

Corey Minyard 50c812b2b9 [PATCH] ipmi: add full sysfs support
Add full driver model support for the IPMI driver.  It links in the proper
bus and device support.

It adds an "ipmi" driver interface that has each BMC discovered by the
driver (as a device).  These BMCs appear in the devices/platform directory.
 If there are multiple interfaces to the same BMC, the driver should
discover this and will only have one BMC entry.  The BMC entry will have
pointers to each interface device that connects to it.

The device information (statistics and config information) has not yet been
ported over to the driver model from proc, that will come later.

This work was based on work by Yani Ioannou.  I basically rewrote it using
that code as a guide, but he still deserves credit :).

Bjorn Helgaas b2c99e3c70 [PATCH] EFI: keep physical table addresses in efi structure
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.

Bjorn Helgaas 27d8e3d15b [PATCH] DMI: only ioremap stuff we actually need
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.

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.

Matt Domsch 3ed3bce846 [PATCH] ia64: use i386 dmi_scan.c
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.

Vivek Goyal 10dbe196a8 [PATCH] i386: export: memory more than 4G through /proc/iomem
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.

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.

Steven Rostedt 64a07bd82e [PATCH] protect remove_proc_entry
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.

Andi Kleen 0b5c59a1e4 [PATCH] Fix compilation of processor_idle.c on IA64
Broken earlier by me by a x86-64 patch.

The code was optimized away, but the compiler still complained about an
undeclared function.

Lennert Buytenhek 104c7b03ea [ARM] 3383/3: ixp2000: ixdp2x01 platform serial conversion
Patch from Lennert Buytenhek

Add a PLAT8250_DEV_PLATFORM2, and convert the two ixdp2x01 CPLD serial
ports to use platform serial devices with ids PLAT8250_DEV_PLATFORM[12].
(The on-chip xscale UART is PLAT8250_DEV_PLATFORM, id #0.)

Nicolas Pitre 2ce9804fbd [ARM] 3030/2: fix permission check in the obscur cmpxchg syscall
Patch from Nicolas Pitre

Quoting RMK:

|pte_write() just says that the page _may_ be writable. It doesn't say
|that the MMU is programmed to allow writes. If pte_dirty() doesn't
|return true, that means that the page is _not_ writable from userspace.
|If you write to it from kernel mode (without using put_user) you'll
|bypass the MMU read-only protection and may end up writing to a page
|owned by two separate processes.

Malcolm Parsons 3ee357f0f3 [ARM] 3399/1: Fix link problem when CONFIG_PRINTK is disabled
Patch from Malcolm Parsons

Printking a backtrace requires printk, so disable backtrace code
when printk is disabled.

Without this patch, a kernel with CONFIG_PRINTK disabled does not link:

arch/arm/lib/lib.a(backtrace.o): In function `c_backtrace':
arch/arm/lib/backtrace.S:(.text+0x108): undefined reference to `printk'

Catalin Marinas 80ed354725 [ARM] 3398/1: Fix the VFP registers loading/storing base address
Patch from Catalin Marinas

The current VFP code corrupts the VFP registers (including the control
ones) if more than one floating point application is executed at the same
time. This patch fixes the updating of the load/store base addresses for
the VFP registers.
