Subject: [PATCH] kexec/kdump : add a new linux, usable-drconf-memory node to the device tree
Add a new linux,usable-drconf-memory property to the device tree passed to the
2nd kernel. Each entry in the property is of the form: a count followed by so
many (base, size) pairs of usable memory regions. The total number of such
entries is equal to number of lmb's in ibm,dynamic-memory property.

Subject: [PATCH] ia64: make PA() work for both physical identity-mapped virtual addresses
The EFI Runtime Services Table contains pointers to ia64 function
descriptors. On existing, pre-Tiano, firmware, SetVirtualAddressMap()
converts *all* these pointers from physical to virtual. On Tiano-based
firmware, the pointer to the SetVirtualAddressMap() function descriptor
is not converted, so it remains a physical pointer.
The ia64 kexec purgatory patches the SetVirtualAddressMap() function
descriptor so that when the new kernel calls SetVirtualAddressMap(), it
never reaches firmware. Instead, it calls a dummy function that just
returns success.
Purgatory runs in physical mode, so it must convert the pointer from the
RuntimeServicesTable to a physical address. This patch makes that
conversion work both for old firmware (where the pointer is an identity-
mapped virtual address) and new Tiano firmware (where the pointer is a
physical address).
Without this patch, kexec on Tiano firmware causes an MCA because
ia64_env_setup() subtracts PAGE_OFFSET from a physical address and ends
up with an invalid physical address. Referencing that address causes
the MCA.

Subject: [patch] ia64: Order of operations bug in PT_LOAD segment reader
This bug was discovered by Jay Lan and he also proposed this fix, however
thee is some discussion about what if any related changes should be made at
the same time.
The bug comes about because the break statment was never executed because
the if clause would bever be true because the if clause will never be true
because & has higher precedence than !=.
My position on this is that with the if logic fixed, as per this patch, the
break statment and the rest of the while() loop makes sense and should work
as intended.
As I understand it, Jay's position is that the code should be simplified,
after all it never worked as intended.
There is a related kernel bug that lead Jay to discover this problem.
The kernel bug has been resolved by Tony Luck and was
included in Linus's tree between 2.6.27-rc8 and 2.6.27-rc9 as
"[IA64] Put the space for cpu0 per-cpu area into .data section".
Now that the kernel bug is out of the way, I am providing this patch to
continue discussion on what to do on the kexec-tools side of things. I do
not intend to apply this patch until there is some conclusion in the
discussion between Jay and myself.

Subject: [PATCH] IA64: do not include uncached memory to vmcore
Currently a memory segment in memory map with attribute of EFI_MEMORY_UC
is denoted as "System RAM" in /proc/iomem, while memory of attribute
(EFI_MEMORY_WB|EFI_MEMORY_UC) is also labeled the same.
The kexec utility then includes uncached memory as part of vmcore.
The kdump kernel may MCA when it tries to save the vmcore to a disk.
A normal "cached" access can cause MCAs.
Since kexec assembled memory ranges with memory tagged as "System RAM",
the uncached memory will be excluded if it is labeled differently.
Simon, since only IA64 will create "Uncached RAM" label, i do not
make changes to other arch.
Our HP machine in the lab is dead. I am sorry that i can not test
against other IA64 systems (than SGI's). Feedback is very much
appreciated.
The corresponding kernel patch is needed to test this kexec patch:
http://marc.info/?l=linux-ia64&m=122122791230130&w=2
This patch without the kernel patch will have no effect and do no
harm.
The kernel patch has been commited as
"[IA64] kexec fails on systems with blocks of uncached memory".

References: bnc#438086
X-Git-Id: 802a8a5e396e06a514251c44454c982bff3c5073
On a powerpc machine when memory is dynamically removed/added from an lpar, the
corresponding flags field in the drconf memory reflects the same with the bits
unset/set accordingly. The kernel does a check on these flags while booting.
Following are the similar changes brought in to kexec-tools. This makes
kexec-tools to skip those memory regions that do not belong or are not
assigned to the current partition ( but are available to dynamically add them
back ). Without this patch (and with memory remove operation) copying vmcore
fails with error as
Copying data : [ 84 %] readmem: Can't read the dump
memory(/proc/vmcore). Bad address

Subject: [PATCH] [PPC64] Fix memory corruption when using realloc_memory_ranges()
Because realloc_memory_ranges() makes the old memory invalid, and we return
a pointer to memory_range in get_memory_ranges(), we need to copy the contents
in get_memory_ranges().
Some code that calls realloc_memory_ranges() may be triggered by
get_base_ranges() which is called after get_memory_ranges().
Yes, the memory needs to be deleted somewhere, but I don't know currently
where it's the best, and since it's not in a loop and memory is deleted
anyway after program termination I don't want to introduce unneccessary
complexity. The problem is that get_base_ranges() gets called from
architecture independent code and that allocation is PPC64-specific here.
