This reverts commit 39d61db0edb34d60b83c5e0d62d0e906578cc707.

The commit was buggy in multiple ways:
 - the conversion to ilog2() was incorrect to begin with
 - it tested the wrong #defines, so on all architectures but FRV you'd
   never see the bug except for constant arguments.
 - the new "get_order()" macro used its arguments multiple times, and
   didn't even parenthesize them properly
 - despite the comments, it was not true that you could use it for
   constant initializers, since not all architectures even use the
   generic page.h header file.

All of the problems are individually fixable, but it all boils down to:
better just revert it, and re-do it from scratch.

When calling write() with a buffer larger than 512 bytes, the

execute arbitrary code with kernel privileges.

In read(), there exists a similar problem, but coming from the device.
A malicous or buggy device sending more than 512 bytes can overflow
of the driver's read buffer, with the same effects as above.

[PATCH] suspend regression: sysfs deadlock

"Driver core: fix race in sysfs between sysfs_remove_file() and
read()/write()".

sysfs_write_file downs buffer->sem while calling flush_write_buffer, and
flushing that particular write buffer entails downing buffer->sem in
orphan_all_buffers, resulting in the obvious self-deadlock.

17 years ago[IA64] kexec: Use EFI_LOADER_DATA for ELF core header
Magnus Damm [Tue, 6 Mar 2007 10:34:26 +0000 (02:34 -0800)] 
[IA64] kexec: Use EFI_LOADER_DATA for ELF core header

The address where the ELF core header is stored is passed to the secondary
kernel as a kernel command line option.  The memory area for this header is
also marked as a separate EFI memory descriptor on ia64.

The separate EFI memory descriptor is at the moment of the type
EFI_UNUSABLE_MEMORY.  With such a type the secondary kernel skips over the
entire memory granule (config option, 16M or 64M) when detecting memory.
If we are lucky we will just lose some memory, but if we happen to have
data in the same granule (such as an initramfs image), then this data will
never get mapped and the kernel bombs out when trying to access it.

So this is an attempt to fix this by changing the EFI memory descriptor
type into EFI_LOADER_DATA.  This type is the same type used for the kernel
data and for initramfs.  In the secondary kernel we then handle the ELF
core header data the same way as we handle the initramfs image.

This patch contains the kernel changes to make this happen.  Pretty
straightforward, we reserve the area in reserve_memory().  The address for
the area comes from the kernel command line and the size comes from the
specialized EFI parsing function vmcore_find_descriptor_size().

The kexec-tools-testing code for this can be found here:

[IA64] permon use-after-free fix

Perfmon associates vmalloc()ed memory with a file descriptor, and installs
a vma mapping that memory.  Unfortunately, the vm_file field is not filled
in, so processes with mappings to that memory do not prevent the file from
being closed and the memory freed.  This results in use-after-free bugs and
multiple freeing of pages, etc.

I saw this bug on an Altix on SLES9.  Haven't reproduced upstream but it
looks like the same issue is there.
