2011-08-28ARM: pm: avoid writing the auxillary control register for ARMv7Russell King
For ARMv7 kernels running in the non-secure world, writing to the auxillary control register causes an abort, so we must avoid directly writing the auxillary control register. If the ACR has already been reinitialized by SoC code, don't try to restore it. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2011-08-28ARM: pm: some ARMv7 requires a dsb in resume to ensure correctnessRussell King
Add a dsb after the isb to ensure that the previous writes to the CP15 registers take effect before we enable the MMU. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2011-08-28ARM: pm: CPU specific code should not overwrite r1 (v:p offset)Russell King
r1 stores the v:p offset from the CPU invariant resume code, and is expected to be preserved by the CPU specific code. Overwriting it is not a good idea. We've managed to get away with it on sa1100 platforms because most happen to have PHYS_OFFSET == PAGE_OFFSET, but that may not be the case depending on kernel configuration. So fix this latent bug. This fixes xsc3 as well which was saving and restoring this register independently. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2011-08-28ARM: 7066/1: proc-v7: disable SCTLR.TE when disabling MMUWill Deacon
cpu_v7_reset disables the MMU and then branches to the provided address. On Thumb-2 kernels, we should take care to clear the Thumb Exception enable bit in the System Control Register, otherwise this may wreak havok in the code to which we are branching (for example, an ARM kernel image via kexec).

2011-08-28ARM: 7065/1: kexec: ensure new kernel is entered in ARM stateWill Deacon
Commit 540b5738 ("ARM: 6999/1: head, zImage: Always Enter the kernel in ARM state") mandates that the kernel should be entered in ARM state. If a Thumb-2 kernel kexecs a new kernel image, we need to ensure that we change state when branching to the new code. This patch replaces a mov pc, lr with a bx lr on Thumb-2 kernels so that we transition to ARM state if need be.

2011-08-24ARM: 7003/1: vexpress: Add clock definition for the SP805.Nick Bowler
It seems that an entry for the SP805 watchdog in the table of clocks was missing.

2011-08-15ARM: 7014/1: cache-l2x0: Fix L2 Cache size calculation.Srinivas Kandagatla
This patch fixes L2 Cache size calculations for L2C-210, L2C-310 and PL310, by changing the L2X0_AUX_CTRL_WAY_SIZE_MASK from 2 bits to 3 bits. The Auxiliary Control Register for L2C-210, L2C-310 and PL310 has 3bits [19:17] for Way size, however the existing code only uses 2 bits to get this value. This results in incorrect cachesize calculations. It also results in performing operations on the whole cache when we erroneously decide that the range is big enough (due to l2x0_size being too small) and also prints incorrect cachesize.

2011-08-12ARM: twd: register clockevents device before enabling PPIWill Deacon
The smp_twd clockevents driver currently enables the local timer PPI before the clockevents device is registered.

2011-08-11move RLIMIT_NPROC check from set_user() to do_execve_common()Vasiliy Kulikov
The patch http://lkml.org/lkml/2003/7/13/226 introduced an RLIMIT_NPROC check in set_user() to check for NPROC exceeding via setuid() and similar functions. Before the check there was a possibility to greatly exceed the allowed number of processes by an unprivileged user if the program relied on rlimit only. But the check created new security threat: many poorly written programs simply don't check setuid() return code and believe it cannot fail if executed with root privileges. So, the check is removed in this patch because of too often privilege escalations related to buggy programs. The NPROC can still be enforced in the common code flow of daemons spawning user processes. Most of daemons do fork()+setuid()+execve(). The check introduced in execve() (1) enforces the same limit as in setuid() and (2) doesn't create similar security issues. Neil Brown suggested to track what specific process has exceeded the limit by setting PF_NPROC_EXCEEDED process flag. With the change only this process would fail on execve(), and other processes' execve() behaviour is not changed. Solar Designer suggested to re-check whether NPROC limit is still exceeded at the moment of execve(). If the process was sleeping for days between set*uid() and execve(), and the NPROC counter step down under the limit, the defered execve() failure because NPROC limit was exceeded days ago would be unexpected. If the limit is not exceeded anymore, we clear the flag on successful calls to execve() and fork(). The flag is also cleared on successful calls to set_user() as the limit was exceeded for the previous user, not the current one. Similar check was introduced in -ow patches (without the process flag). v3 - clear PF_NPROC_EXCEEDED on successful calls to set_user().

This reverts commit af9d220bac41dc3201893e1601cc7c44f7da4498. It turns out that one was meant to be applied on top of the edac.git tree in -next that has more i7core_edac changes, but that wasn't clear in the original email.

2011-08-11NFS41: make PNFS_BLOCK selectablePeng Tao
PNFS_BLOCK needs BLK_DEV_DM/MD, which is not a dependency for other pnfs layout drivers. Seperate it out so others can still build when BLK_DEV_DM/MD is not enabled. Also change select to depends on to avoid build failures.

2011-08-11PCnet: Fix section mismatchRalf Baechle
Building MIPS mtx1_defconfig results in: MODPOST 735 modules WARNING: drivers/net/pcnet32.o(.devinit.text+0x11ec): Section mismatch in reference from the function pcnet32_probe_vlbus.constprop.22() to the variable .init.data:pcnet32_portlist The function __devinit pcnet32_probe_vlbus.constprop.22() references a variable __initdata pcnet32_portlist. If pcnet32_portlist is only used by pcnet32_probe_vlbus.constprop.22 then annotate pcnet32_portlist with a matching annotation.
