+Subject: [PATCH] Fix compile error on ppc/uClibc platform: 'AT_BASE_PLATFORM'
+ undeclared'
+
+This issue was reported via bug #245.
+
+The method for obtaining cpu type on the ppc64 platform was recently
+modified to detect the case when we're running on a kernel that has
+not been updated to recognize the native processor type. The cpu
+type returned in the case where the native processor type is newer
+than POWER7 will be "CPU_PPC64_ARCH_V1" (architected CPU type).
+The method used for detecting when the kernel does not recognize the
+native processor type is to inspect the aux vector and compare
+AT_PLATFORM and AT_BASE_PLATFORM. The 'AT_BASE_PLATFORM' was defined
+in glibc's elf.h around 5 years ago, but was never added to uClibc,
+so the code that implements the above-described method fails to compile
+on systems using uClibc.
+
+Since the above-described method of using the aux vector is only
+required for ppc64 systems, and ppc64-based platforms always use glibc
+(which has the AT_BASE_PLATFORM macro defined), we now wrap that code
+with '#if PPC64_ARCH' to prevent problems on other architectures.

-Subject: [PATCH] Fix PPC64-specific libpfm usage so it doesn't break ppc32
- architecture
-
-The configure check to determine whether we should use libpfm or not
-is intended only for the ppc64 architecture, but was incorrectly
-hitting on the ppc32 architecture, too. Not only that, but it was using
-'uname' which is not a good idea in cross-compile situtations.
-
-Then, aside from that, we had several instances in the source code
-of the following:
- #if (defined(__powerpc__) || defined(__powerpc64__))
-which incorrectly included ppc32 architecutre also, when it was intended
-for use as PPC64 architecture.
-
-This patch fixes both errors.

-Subject: [PATCH] Fix up configure to handle architectures that do not
- implement perf_event_open
-
-This patch fixes the following problems:
-
-1) The configure script allows the user to pass a location to kernel
-headers (via --with-kernel option) such that, even if the running
-kernel does not have perf_events support, it may be possible to
-build operf (e.g., in cross-compile environments). But the message
-'This kernel does not have perf_events support; falling back to legacy
-oprofile' was being displayed inappropriately in such cases. This
-patch changes the configure script so that the "falling back to
-legacy oprofile" message will only be displayed if we're running
-on a kernel that does not have perf_events support AND the user
-did not pass specify the "--with-kernel" option.
-
-2) Some architectures don't even implement the perf_event_open syscall, so the
-configure script must do more than checking kernel version and whether or not
-perf_event.h is present in order to decide if perf_events is supported.
-This patch provides that extra capability.
-
-These problems were reported by Tony Jones <tonyj@suse.com>.
