There is a possibility that get_page_bootmem() is called to the same page many
times. So when get_page_bootmem is called to the same page, the function only
increments page->_count.

The patch adds __remove_pages() to remove_memory(). Then the range of
phys_start_pfn argument and nr_pages argument in __remove_pagse() may
have different zone. So zone argument is removed from __remove_pages()
and __remove_pages() caluculates zone in each section.

When calling remove_memory_block(), the function shows following message at
device_release().
Device 'memory528' does not have a release() function, it is broken and must
be fixed.
remove_memory_block() calls kfree(mem). I think it shouled be called from
device_release(). So the patch implements

When (hot)adding memory into system, /sys/firmware/memmap/X/{end, start, type}
sysfs files are created. But there is no code to remove these files. The patch
implements the function to remove them.
Note : The code does not free firmware_map_entry since there is no way to free
memory which
There are two ways to create /sys/firmware/memmap/X sysfs:
- firmware_map_add_early
When the system starts, it is calledd from e820_reserve_resources()
- firmware_map_add_hotplug
When the memory is hot plugged, it is called from add_memory()
But these functions are called without
acpi_memory_device_remove() has been prepared to remove physical memory.
But, the function only frees acpi_memory_device currentlry.
The patch adds following functions into acpi_memory_device_remove():
- offline memory
- remove physical memory (only return -EBUSY)
- free acpi_memory_device

You have two options:

- You wait for a pull request with both patches + the
remove_memory() does not remove memory but just offlines memory. The patch

The 2012 series of MacBooks have a faster SMC, and the current driver
timings do not work at all. Tests show that decreasing the minimum
wait time, from 64 us to 16 us, works well. Since this is still larger
than the original minimum of 10 us used before 2008, there is nothing

In functions itd_complete & sitd_complete, a pointer
by name stream may get dereferenced after freeing it, when
iso_stream_put is called with stream->refcount = 2.
Hence fixing it.

Hi!
Still the problem seems to be related to the sysfs:
# cd /tmp
# touch testfile
# chmod u=w,go= testfile
# F=/tmp/testfile
# test -r "$F" && cat "$F"
So it seems access(2) works correctly for root and "normal" filesystems. That's
why I came up with the issue here.

dev->priomap is allocated by extend_netdev_table() called from
update_netdev_tables().
And this is only called if write_priomap() is called.
But if write_priomap() is not called, it seems we can have out of bounds
accesses in cgrp_destroy(), read_priomap() & skb_update_prio()

If list_for_each_entry, etc complete a traversal of the list, the iterator
variable ends up pointing to an address at an offset from the list head,
and not a meaningful structure. Thus this value should not be used after
the end of the iterator. Replace a field access from

This patch tries to fix a dead loop in async_synchronize_full(), which
could be seen when preemption is disabled on a single cpu machine.
void async_synchronize_full(void)

And Peter no rush on these. I have just finished testing and I am
pushing the changes out before I forget them.
Moving the Elf loader earlier to compile time makes the code a lot
more robust.

By default ld uses 2MB pages and aligns our 3 program segments in the
file on 2MB boundaries, creating unnecessarily large uncompressed
vmlinux files.
Solve this by passing -z max-page-size 4096 to ld.
In my test x86_64 SMP test configuration with CONFIG_DEBUG_RODATA
enabled, this reduces the
The ELF loader in arch/x86/boot/compressed/misc.c is extremely
fragile, as it copies the ELF executable over itself to put the
code and data in their proper place. Squeezing unneeded space
out of vmlinux by passing -z max-page-size 4096 to ld was enough
to render the kernel unbootable.

Hi all,
Changes since 20120706:
I have not done the powerpc allyesconfig build today as it is too broken.
Undropped tree: gpio-lw
The jdelvare-hwmon tree lost its conflict.
The v4l-dvb tree gained a build failure so I used the version from
next-20120706.
The infiniband tree lost its build
Create a space for the elf headers at the begginng of the kernels
image in memory.
- Rework arch/x86/kernel/vmlinux.lds.S so that we allow room for
the ELF header in the loaded image. This removes the need in
the ELF executalbe to insert padding between the ELf headers
and the data of the
Since we have the kernel's entry point stored in the ELF header use it,
and stop hardcoding the value.

Francois, what would you like me to do with these two patches? I
haven't seen full ACKs from you yet.

Noting pause loop exited vcpu helps in filtering right candidate to yield.
Yielding to same vcpu may result in more wastage of cpu.
