And commit: ("allow stripping of generated symbols under CONFIG_KALLSYMS_ALL")
9bb482476c6c9d1ae033306440c51ceac93ea80cThese stripping patches has caused a set of issues:
1) People have reported compatibility issues with binutils due to
lack of support for `--strip-unneeded-symbols' with objcopy 2.15.92.0.2
Reported by: Wenji
2) ccache and distcc no longer works as expeced
Reported by: Ted, Roland, + others
3) The installed modules increased a lot in size

Impact: reduce scope of debug check - avoid warnings
The logic to find whether identity map exists or not using
high_memory or max_low_pfn_mapped/max_pfn_mapped are not complete
as the memory withing the range may not be mapped if there is a
unusable hole in e820.Specifically, on my test system I started seeing these warnings with
tools like hwinfo, acpidump trying to map ACPI region.[ 27.400018] ------------[ cut here ]------------

identity map when we have 1GB of aligned reserved space in e820.This patch handles it by removing the WARN_ON and returning a specific

this error, with other callers of cpa still getting error here.Signed-off-by: Venkatesh Pallipadi

Impact: avoid warning message, potentially solve 3D performance regression
Change x86 PAT code to return compatible memtype if the exact memtype that
was requested in remap_pfn_rage and friends is not available due to some
conflict.This is done by returning the compatible type in pgprot parameter of
track_pfn_vma_new(), and the caller uses that memtype for page table.Note that track_pfn_vma_copy() which is basically called during fork gets the
prot from existing page table and should not have any conflict. Hence we use
strict memtype check there and do not allow compatible memtypes.This patch fixes the bug reported here:
http://marc.info/?l=linux-kernel&m=123108883716357&w=2
Specifically the error message:
X:5010 map pfn expected mapping type write-back for d0000000-d0101000,

Support for the FPGA based watchdog timer on GE Fanuc's SBC610.
This patch enables one of the watchdog timers found on the SBC610. There are
two identical watchdog timers at different offsets in the above mentioned
boards, however the current driver is only capable of supporting one of them.The watchdog timers are also capable of generating interrupts at a
user-configurable threshold, though support for this operation is currently
not supported by the driver.Signed-off-by: Martyn Welch

This reverts commit 7503bfbae89eba07b46441a5d1594647f6b8ab7d.
Dieter Ries reported bootup soft-hangs and bisected it back to
this commit, and reverting this commit gave him a working system.The commit introduces work_on_cpu() use into the cpufreq code,
but that is subtly problematic from a lock hierarchy POV: the
hotplug-cpu lock is an highlevel lock that is taken before
lowlevel locks, and in this codepath we are called with the
policy lock taken.Dieter did not have lockdep enabled so we dont have a nice stack
trace proof for this, but using work_on_cpu() in such a lowlevel
place certainly looks wrong, so we revert the patch.work_on_cpu() needs to be reworked to be more generally usable.

Ajith Kumar noticed:
I was going through the vmalloc fault handling for x86_64 and am unclear
about the following lines in the vmalloc_fault() function.pgd = pgd_offset(current->mm ?: &init_mm, address);
pgd_ref = pgd_offset_k(address);Here the intention is to get the pgd corresponding to the current process
and sync it up with the pgd in init_mm(obtained from pgd_offset_k).
However, for kernel threads current->mm is NULL and hence pgd =
pgd_offset(init_mm, address) = pgd_ref which means the fault handler
returns without setting the pgd entry in the MM structure in the context
of which the kernel thread has faulted. This could lead to never-ending
faults and busy looping of kernel threads like pdflush. So, shouldn't the
pgd = pgd_offset(current->mm ?: &init_mm, address); be pgd =
pgd_offset(current->active_mm ?: &init_mm, address);We can use active_mm unconditionally because it should be always set.
