+Subject: [PATCH] top: fix and merge code to parse /proc/meminfo
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+display_header() code to parse meminfo as is was buggy:
+- uninitialized variables were used if meminfo was not as expected
+- meminfo parsing failed on new kernels (3.14+) as new field 'MemAvailable'
+ was introduced between MemFree and Buffers
+- shared memory was handled only for ancient kernels (2.4.x and earlier)
+
+as result Buffers and shared memory fields were shown with bogus values
+on current kernels.
+
+The new code does not try to parse the old style summary header, as the
+separated fields are always present (it saves code size). Additionally,
+both Shmem (2.6+) and MemShared (2.4 and earlier) fields are now parsed
+and summed for shared memory usage; as only one of them exists depending
+on kernel version.
+
+display_topmem_header() parses also meminfo so this makes it use the
+same code for code shrink.
