cpuid_class_cpu_callback() is callback function of a CPU hotplug
notifier_block (that is already marked as __cpuinitdata). Therefore
it can safely be marked as __cpuinit.

cpuid_device_create() is only referenced from other functions that
are __cpuinit or __init. So it can also be safely marked __cpuinit.

cache_shared_cpu_map_setup() and cache_remove_shared_cpu_map()
are functions called from another function that is __cpuinit.  But the
!CONFIG_SMP empty-body stubs of these functions are unconditionally
marked __init, which is actively wrong, and will lead to oops.  But we
never saw this oops, because they always managed to get inlined in their
callsites, by virtue of being empty-body stubs!  They should still be
__cpuinit, of course.

assocs[], levels[] and types[] are only referenced from function that is
__cpuinit.  So these are candidates for being marked __cpuinitdata.

  biosdevname is a userspace app I wrote to help solve this so we don't need
  to patch the kernel for future systems.  It's not integrated into any
  distributions properly yet, but is included in openSUSE 10.3 and Fedora 8
  for people who want to download and install it there.  It acts as a udev

  For the time being, patching the kernel is necessary.  I really hope

This patch fixes a bug of change_page_attr/change_page_attr_addr on
Intel x86_64 CPUs.  After changing page attribute to be executable with
these functions, the page remains un-executable on Intel x86_64 CPU.
Because on Intel x86_64 CPU, only if the "NX" bits of all four level
page tables are cleared, the corresponding page is executable (refer to
section 4.13.2 of Intel 64 and IA-32 Architectures Software Developer's
Manual).  So, the bug is fixed through clearing the "NX" bit of PMD when
splitting the huge PMD.

if CONFIG_PAGEALLOC is enabled then X86_FEATURE_PSE is disabled and all
the kernel physical RAM pagetables are set up as 4K pages. This is
needed so that CONFIG_PAGEALLOC can do finegrained mapping and unmapping
of pages.

as a side-effect though, the total size of memory allocated as kernel
pagetables increases significantly. All these pagetables are allocated
via alloc_bootmem_low_pages(), straight out of the lowmem DMA pool. If
the system has enough RAM and a large kernel image then almost all of
the 16 MB lowmem DMA pool is allocated to the image and to pagetables -
leaving no space for __GFP_DMA allocations.

this results in drivers failing and the bootup hanging:

  =======================

the fix is to first allocate from above the DMA pool, and if that fails
(for example due to it being a machine with less than 16 MB of RAM),
allocate from the DMA pool as a fallback.

With this fix applied i was able to boot a PAGEALLOC=y kernel that would

Some gcc versions (I checked at least 4.1.1 from RHEL5 & 4.1.2 from gentoo)
can generate incorrect code with read_crX()/write_crX() functions mix up,
due to cached results of read_crX().

The small app for x8664 below compiled with -O2 demonstrates this
(i686 does the same thing):

notifier callback function itself has been marked __cpuinit which becomes

Fix get_apic_id() in mach-default, so that it uses 8 bits incase of
xAPIC case and 4 bits for legacy APIC case.

This fixes the i386 kernel assumption that apic id is less than 16 for
xAPIC platforms with 8 cpus or less and makes the kernel boot on such
platforms.

This keeps an unstripped copy of the 64bit vDSO images built before they are
stripped and embedded in the kernel.  The unstripped copies get installed
in $(MODLIB)/vdso/ by "make install" (or you can explicitly use the
subtarget "make vdso_install").  These files can be useful when they
contain source-level debugging information.
