+
+This patch adds support for TIF_RESTORE_SIGMASK to ARM's signal handling,
+which allows to hook up the pselect6, ppoll, and epoll_pwait syscalls on ARM.
+
+Tested here with eabi userspace and a test program with a deliberate race
+between a child's exit and the parent's sigprocmask/select sequence.
+Using sys_pselect6() instead of sigprocmask/select reliably prevents the race.
+
+The other arch's support for TIF_RESTORE_SIGMASK has evolved over time:
+
+In 2.6.16:
+- add TIF_RESTORE_SIGMASK which parallels TIF_SIGPENDING
+- test both when checking for pending signal [bad, changed later]
+- reimplement sys_sigsuspend() to use current->saved_sigmask,
+ TIF_RESTORE_SIGMASK [changed later], and -ERESTARTNOHAND;
+ ditto for sys_rt_sigsuspend(), but drop private code and
+ use common code via __ARCH_WANT_SYS_RT_SIGSUSPEND;
+- there are now no "extra" calls to do_signal() so its oldset
+ parameter is always &current->blocked so need not be passed,
+ also its return value is changed to void
+- change handle_signal() to return 0/-errno
+- change do_signal() to honor TIF_RESTORE_SIGMASK:
+ + get oldset from current->saved_sigmask if TIF_RESTORE_SIGMASK is set
+ + if handle_signal() was successful then clear TIF_RESTORE_SIGMASK
+ + if no signal was delivered and TIF_RESTORE_SIGMASK is set then
+ clear it and restore the sigmask
+- hook up sys_pselect6() and sys_ppoll()
+
+In 2.6.19:
+- hook up sys_epoll_pwait()
+
+In 2.6.26:
+- allow archs to override how TIF_RESTORE_SIGMASK is implemented;
+ default set_restore_sigmask() sets both TIF_RESTORE_SIGMASK and
+ TIF_SIGPENDING; archs need now just test TIF_SIGPENDING again
+ when checking for pending signal work; some archs now implement
+ TIF_RESTORE_SIGMASK as a secondary/non-atomic thread flag bit
+- call set_restore_sigmask() in sys_sigsuspend() instead of setting
+ TIF_RESTORE_SIGMASK
+
+In 2.6.29-rc:
+- kill sys_pselect7() which no arch wanted
+
+So for 2.6.31-rc6/ARM this patch does the following:
+- Add TIF_RESTORE_SIGMASK. Use the generic set_restore_sigmask()
+ which sets both TIF_SIGPENDING and TIF_RESTORE_SIGMASK, so
+ TIF_RESTORE_SIGMASK need not claim one of the scarce low thread
+ flags, and existing TIF_SIGPENDING and _TIF_WORK_MASK tests need
+ not be extended for TIF_RESTORE_SIGMASK.
+- sys_sigsuspend() is reimplemented to use current->saved_sigmask and
+ set_restore_sigmask(), making it identical to most other archs.
+- The private code for sys_rt_sigsuspend() is removed, instead generic
+ code supplies it via __ARCH_WANT_SYS_RT_SIGSUSPEND.
+- sys_sigsuspend() and sys_rt_sigsuspend() no longer need a pt_regs
+ parameter, so their assembly code wrappers are removed.
+- handle_signal() is changed to return 0 on success or -errno.
+- The oldset parameter to do_signal() is now redundant and removed,
+ and the return value is now also redundant so it's changed to void.
+- do_signal() is changed to honor TIF_RESTORE_SIGMASK:
+ + get oldset from current->saved_sigmask if TIF_RESTORE_SIGMASK is set
+ + if handle_signal() was successful then clear TIF_RESTORE_SIGMASK
+ + if no signal was delivered and TIF_RESTORE_SIGMASK is set then
+ clear it and restore the sigmask
+- Hook up sys_pselect6, sys_ppoll, and sys_epoll_pwait.
+
+Signed-off-by: Mikael Pettersson
+---
+Changes from previous versions:
+
+v2 (only posted as incremental diff against v1):
+- moved sigmask restoration in no-signal-delivered case into
+ "if (syscall)" block for extra protection against exception
+ path also invoking do_signal()
+v3 (this version):
+- moved oldset initialisation into "if (signr > 0)" block,
+ as requested by Russell

+From: Mike Frysinger <vapier@gentoo.org>
+Date: Thu, 17 May 2007 14:57:20 -0400
+Subject: [PATCH] kbuild: include limits.h in sumversion.c for PATH_MAX
+
+POSIX says limits.h defines PATH_MAX so we should include it (which fixes
+compiling on some systems like OS X).

++Group scheduler extension to CFS
++================================
++
++Normally the scheduler operates on individual tasks and strives to provide
++fair CPU time to each task. Sometimes, it may be desirable to group tasks
++and provide fair CPU time to each such task group. For example, it may
++be desirable to first provide fair CPU time to each user on the system
++and then to each task belonging to a user.
++
++CONFIG_FAIR_GROUP_SCHED strives to achieve exactly that. It lets
++SCHED_NORMAL/BATCH tasks be be grouped and divides CPU time fairly among such
++groups. At present, there are two (mutually exclusive) mechanisms to group
++tasks for CPU bandwidth control purpose:
++
++ - Based on user id (CONFIG_FAIR_USER_SCHED)
++ In this option, tasks are grouped according to their user id.
++ - Based on "cgroup" pseudo filesystem (CONFIG_FAIR_CGROUP_SCHED)
++ This options lets the administrator create arbitrary groups
++ of tasks, using the "cgroup" pseudo filesystem. See
++ Documentation/cgroups.txt for more information about this
++ filesystem.
++
++Only one of these options to group tasks can be chosen and not both.
++
++Group scheduler tunables:
++
++When CONFIG_FAIR_USER_SCHED is defined, a directory is created in sysfs for
++each new user and a "cpu_share" file is added in that directory.
++
++ # cd /sys/kernel/uids
++ # cat 512/cpu_share # Display user 512's CPU share
++ 1024
++ # echo 2048 > 512/cpu_share # Modify user 512's CPU share
++ # cat 512/cpu_share # Display user 512's CPU share
++ 2048
++ #
++
++CPU bandwidth between two users are divided in the ratio of their CPU shares.
++For ex: if you would like user "root" to get twice the bandwidth of user
++"guest", then set the cpu_share for both the users such that "root"'s
++cpu_share is twice "guest"'s cpu_share
++
++
++When CONFIG_FAIR_CGROUP_SCHED is defined, a "cpu.shares" file is created
++for each group created using the pseudo filesystem. See example steps
++below to create task groups and modify their CPU share using the "cgroups"
++pseudo filesystem
++
++ # mkdir /dev/cpuctl
++ # mount -t cgroup -ocpu none /dev/cpuctl
++ # cd /dev/cpuctl
++
++ # mkdir multimedia # create "multimedia" group of tasks
++ # mkdir browser # create "browser" group of tasks
++
++ # #Configure the multimedia group to receive twice the CPU bandwidth
++ # #that of browser group
++
++ # echo 2048 > multimedia/cpu.shares
++ # echo 1024 > browser/cpu.shares
++
++ # firefox & # Launch firefox and move it to "browser" group
++ # echo <firefox_pid> > browser/tasks
++
++ # #Launch gmplayer (or your favourite movie player)
++ # echo <movie_player_pid> > multimedia/tasks

-
-This prevents the modules failing to load when made
-with modern toolchains. There is no way to prevent binutils
-to generate these relocations, and on the 920t they are
-in fact not needed. So this patch just skip them.

-Subject: [PATCH] GRO: Disable GRO on legacy netif_rx path
-
-When I fixed the GRO crash in the legacy receive path I used
-napi_complete to replace __napi_complete. Unfortunately they're
-not the same when NETPOLL is enabled, which may result in us
-not calling __napi_complete at all.
-
-What's more, we really do need to keep the __napi_complete call
-within the IRQ-off section since in theory an IRQ can occur in
-between and fill up the backlog to the maximum, causing us to
-lock up.
-
-Since we can't seem to find a fix that works properly right now,
-this patch reverts all the GRO support from the netif_rx path.
