+
+Use NR_ACTIVE plus NR_INACTIVE as a size estimate for our fake cache
+instead the sum of rss. Neither method is accurate.
+
+Also skip the process scan, if the amount of memory available is above

+This fixes a problem where the first pageblock got marked MIGRATE_RESERVE even

+to be reserved and frequent kswapd wakeups that emptied the caches to get more
+contiguous memory.

+Subject: [PATCH 068/134] PM: Enable early suspend through /sys/power/state
+
+If EARLYSUSPEND is enabled then writes to /sys/power/state no longer
+blocks, and the kernel will try to enter the requested state every
+time no wakelocks are held. Write "on" to resume normal operation.

+Subject: [PATCH 069/134] PM: Add user-space wake lock api.
+
+This adds /sys/power/wake_lock and /sys/power/wake_unlock.
+Writing a string to wake_lock creates a wake lock the
+first time is sees a string and locks it. Optionally, the
+string can be followed by a timeout.
+To unlock the wake lock, write the same string to wake_unlock.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=utf-8
+Content-Transfer-Encoding: 8bit
+
+Rather than signaling a full update of the display from userspace via a
+console switch, this patch introduces 2 files int /sys/power,
+wait_for_fb_sleep and wait_for_fb_wake.  Reading these files will block
+until the requested state has been entered.  When a read from
+wait_for_fb_sleep returns userspace should stop drawing.  When
+wait_for_fb_wake returns, it should do a full update.  If either are called
+when the fb driver is already in the requested state, they will return
+immediately.

+Subject: [PATCH 082/134] sysfs_net_ipv4: Add sysfs-based knobs for controlling TCP window size
+
+Add a family of knobs to /sys/kernel/ipv4 for controlling the TCP window size:
+
+	tcp_wmem_min
+	tcp_wmem_def
+	tcp_wmem_max
+	tcp_rmem_min
+	tcp_rmem_def
+	tcp_rmem_max
+
+This six values mirror the sysctl knobs in /proc/sys/net/ipv4/tcp_wmem and
+/proc/sys/net/ipv4/tcp_rmem.
+
+Sysfs, unlike sysctl, allows us to set and manage the files' permissions and
+owners.

+
+  With this feature enabled, mmcblk will check the card-status before issuing
+a transaction *only* after being resumed. This protectes us from issuing
+transactions before the sdcard is ready (which can occur if the host driver
+deferrs mmc_resume_host() to reduce resume latency)

+Subject: [PATCH 123/134] [ARM] goldfish: events: Add event driver for goldfish
+
+this device is a direct pipe from "hardware" to the input

+From: Ye Wen <[email protected]>

+Subject: [PATCH 129/134] [ARM] goldfish: qemutrace: Kernel instrumentation for tracing the events.
+
+Like fork, context switch, execve and exit.
+This code is to complement Jack's tracing facility.
+
+To turn tracing on:
+echo 1 > /sysfs/qemu_trace/state
+To turn tracing off: echo 0 > /sysfs/qemu_trace/state
+I also added java methods to Debug.java to turn tracing on and off.
+The kernel driver also supports adding dynamic symbols to the trace.
+To add a symbol 'foo' with hex address 'abcd1234' to the trace:
+echo 'abcd1234 foo' > /sysfs/qemu_trace/symbol
+
+Signed-off-by: Mike Chan <[email protected]>
+
+[ARM] goldfish: qemutrace: Improved support for tracing thread and process names.
+
+Added a new pseudo file /sys/qemu_trace/process_name to allow user
+programs to add a trace record for a process name change.  Removed
+the tracing of thread and process names from the exit() system call
+because that was not sufficiently general.  Added tracing of thread
+names in set_task_comm() and daemonize().  Added tracing of the
+thread group id to fork() and clone().
