Revert parts of "hlist: drop the node parameter from iterators"
Commit
b67bfe0d42ca ("hlist: drop the node parameter from iterators")
did a lot of nice changes but also contains two small hunks that seem to
have slipped in accidentally and have no apparent connection to the
intent of the patch.
This reverts the two extraneous changes.

idr: remove WARN_ON_ONCE() on negative IDs
idr_find(), idr_remove() and idr_replace() used to silently ignore the
sign bit and perform lookup with the rest of the bits. The weird behavior
has been changed such that negative IDs are treated as invalid. As the
behavior change was subtle, WARN_ON_ONCE() was added in the hope of
determining who's calling idr functions with negative IDs so that they can
be examined for problems.
Up until now, all two reported cases are ID number coming directly from
userland and getting fed into idr_find() and the warnings seem to cause
more problems than being helpful. Drop the WARN_ON_ONCE()s.

What was needed to use HDMI functionality was to select HDMI (which this

drm/mgag200: Bug fix: Renesas board now selects native resolution.
Renesas boards were consistently defaulting to the 1024x768 resolution,
regardless of the native resolution of the monitor plugged in. It was
determined that the EDID of the monitor was not being read. Since the
DAC is a shared line, in order to read from or write to it we must take
control of the DAC clock. This can be done by setting the proper
register to one.
This bug fix sets the register MGA1064_GEN_IO_CTL2 to one. The DAC
control line can be used to determine whether or not a new monitor has
been plugged in. But since the hotplug feature is not one we will
support, it has been decided to simply leave the register set to one.

x86: Do not try to sync identity map for non-mapped pages
kernel_map_sync_memtype() is called from a variety of contexts. The
pat.c code that calls it seems to ensure that it is not called for
non-ram areas by checking via pat_pagerange_is_ram(). It is important
that it only be called on the actual identity map because there *IS*
no map to sync for highmem pages, or for memory holes.
The ioremap.c uses are not as careful as those from pat.c, and call
kernel_map_sync_memtype() on PCI space which is in the middle of the
kernel identity map _range_, but is not actually mapped.
This patch adds a check to kernel_map_sync_memtype() which probably
duplicates some of the checks already in pat.c. But, it is necessary
for the ioremap.c uses and shouldn't hurt other callers.
I have reproduced this bug and this patch fixes it for me and the

ARM: 7668/1: fix memset-related crashes caused by recent GCC (4.7.2) optimizations
Recent GCC versions (e.g. GCC-4.7.2) perform optimizations based on
assumptions about the implementation of memset and similar functions.
The current ARM optimized memset code does not return the value of
its first argument, as is usually expected from standard implementations.
For instance in the following function:
void debug_mutex_lock_common(struct mutex *lock, struct mutex_waiter *waiter)
{
memset(waiter, MUTEX_DEBUG_INIT, sizeof(*waiter));
waiter->magic = waiter;
INIT_LIST_HEAD(&waiter->list);
}
compiled as:
800554d0 <debug_mutex_lock_common>:
800554d0:
e92d4008 push {r3, lr}
800554d4:
e1a00001 mov r0, r1
800554d8:
e3a02010 mov r2, #16 ; 0x10
800554dc:
e3a01011 mov r1, #17 ; 0x11
800554e0:
eb04426e bl
80165ea0 <memset>
800554e4:
e1a03000 mov r3, r0
800554e8:
e583000c str r0, [r3, #12]
800554ec:
e5830000 str r0, [r3]
800554f0:
e5830004 str r0, [r3, #4]
800554f4:
e8bd8008 pop {r3, pc}
GCC assumes memset returns the value of pointer 'waiter' in register r0; causing
register/memory corruptions.
This patch fixes the return value of the assembly version of memset.
It adds a 'mov' instruction and merges an additional load+store into
existing load/store instructions.
For ease of review, here is a breakdown of the patch into 4 simple steps:
Step 1
======
Perform the following substitutions:
ip -> r8, then
r0 -> ip,
and insert 'mov ip, r0' as the first statement of the function.
At this point, we have a memset() implementation returning the proper result,
but corrupting r8 on some paths (the ones that were using ip).
Step 2
======
Make sure r8 is saved and restored when (! CALGN(1)+0) == 1:
save r8:
- str lr, [sp, #-4]!
+ stmfd sp!, {r8, lr}
and restore r8 on both exit paths:
- ldmeqfd sp!, {pc} @ Now <64 bytes to go.
+ ldmeqfd sp!, {r8, pc} @ Now <64 bytes to go.
(...)
tst r2, #16
stmneia ip!, {r1, r3, r8, lr}
- ldr lr, [sp], #4
+ ldmfd sp!, {r8, lr}
Step 3
======
Make sure r8 is saved and restored when (! CALGN(1)+0) == 0:
save r8:
- stmfd sp!, {r4-r7, lr}
+ stmfd sp!, {r4-r8, lr}
and restore r8 on both exit paths:
bgt 3b
- ldmeqfd sp!, {r4-r7, pc}
+ ldmeqfd sp!, {r4-r8, pc}
(...)
tst r2, #16
stmneia ip!, {r4-r7}
- ldmfd sp!, {r4-r7, lr}
+ ldmfd sp!, {r4-r8, lr}
Step 4
======
Rewrite register list "r4-r7, r8" as "r4-r8".

Btrfs: improve the delayed inode throttling
The delayed inode code batches up changes to the btree in hopes of doing
them in bulk. As the changes build up, processes kick off worker
threads and wait for them to make progress.
The current code kicks off an async work queue item for each delayed
node, which creates a lot of churn. It also uses a fixed 1 HZ waiting
period for the throttle, which allows us to build a lot of pending
work and can slow down the commit.
This changes us to watch a sequence counter as it is bumped during the
operations. We kick off fewer work items and have each work item do
more work.

When boot_params->sentinel is set, all we really know is that some

particular case of efi_info, however, there is a private magic for
that substructure, so it is generally safe to leave it even if the
bootloader is broken.
kexec (for which we did the initial analysis) did not initialize this
field, but of course all the EFI bootloaders do, and most EFI

It turns out that we do not calculate the real_end properly:
We try to get 2M size with 4K alignment, and later will round down
to 2M, so we will get less then 2M for first mapping, in extreme
case could be only 4K only. In Henrik's system it has (1M-32K) as
last usable rage is [mem 0x7f9db000-0x7fef8fff].
The problem is exposed when EFI booting have several holes and it
will force mapping to use PTE instead as we only map usable areas.
To fix it, just make it be 2M aligned, so we can be guaranteed to be
able to use large pages to map it.
