2012-04-17ARM: at91: uncompress: autodetect the uart to useJean-Christophe PLAGNIOL-VILLARD
This will now autodetect the first uart enabled by the bootloader and will use it for uncompress. This will still assume that the bootloader configured it (pins and clock). This also allows to include all soc headers together. Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Acked-by: Nicolas Ferre <nicolas.ferre@atmel.com>

2012-04-15ARM: 7384/1: ThumbEE: Disable userspace TEEHBR access for !CONFIG_ARM_THUMBEEJonathan Austin
Currently when ThumbEE is not enabled (!CONFIG_ARM_THUMBEE) the ThumbEE register states are not saved/restored at context switch. The default state of the ThumbEE Ctrl register (TEECR) allows userspace accesses to the ThumbEE Base Handler register (TEEHBR). This can cause unexpected behaviour when people use ThumbEE on !CONFIG_ARM_THUMBEE kernels, as well as allowing covert communication - eg between userspace tasks running inside chroot jails. This patch sets up TEECR in order to prevent user-space access to TEEHBR when !CONFIG_ARM_THUMBEE. In this case, tasks are sent SIGILL if they try to access TEEHBR.

2012-04-15ARM: 7359/2: smp_twd: Only wait for reprogramming on active cpusLinus Walleij
During booting of cpu1, there is a short window where cpu1 is online, but not active where cpu1 is occupied by waiting to become active. If cpu0 then decides to schedule something on cpu1 and wait for it to complete, before cpu0 has set cpu1 active, we have a deadlock. Typically it's this CPU frequency transition that happens at this time, so let's just not wait for it to happen, it will happen whenever the CPU eventually comes online instead.

2012-04-10ARM: 7377/1: vic: re-read status register before dispatching each IRQ handlerWill Deacon
handle_IRQ may briefly cause interrupts to be re-enabled during soft IRQ processing on the exit path, leading to nested handling of VIC interrupts. Since the current code does not re-read the VIC_IRQ_STATUS register, this can lead to multiple invocations of the same interrupt handler and spurious interrupts to be reported. This patch changes the VIC interrupt dispatching code to re-read the status register each time, avoiding duplicate invocations of the same handler.

commit 8878a539ff19a43cf3729e7562cd528f490246ae was done by me to make the page fault handler retryable as well as interruptible. Due to this commit, there is a mistake in the way in which tsk->[maj|min]_flt counter gets incremented for VM_FAULT_ERROR: If VM_FAULT_ERROR is returned in the fault flags by handle_mm_fault, then either maj_flt or min_flt will get incremented. This is wrong as in the case of a VM_FAULT_ERROR we need to be skip ahead to the error handling code in do_page_fault. Added a check after the call to __do_page_fault() to check for (fault & VM_FAULT_ERROR).

Many users of debugfs copy the implementation of default_open() when they want to support a custom read/write function op. This leads to a proliferation of the default_open() implementation across the entire tree. Now that the common implementation has been consolidated into libfs we can replace all the users of this function with simple_open(). This replacement was done with the following semantic patch: <smpl> @ open @ identifier open_f != simple_open; identifier i, f; @@ -int open_f(struct inode *i, struct file *f) -{ ( -if (i->i_private) -f->private_data = i->i_private; | -f->private_data = i->i_private; ) -return 0; -} @ has_open depends on open @ identifier fops; identifier open.open_f; @@ struct file_operations fops = { ... -.open = open_f, +.open = simple_open, ... }; </smpl> [akpm@linux-foundation.org: checkpatch fixes] Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-04-05ARM: fix __io macro for PCMCIARob Herring
With commit c334bc1 (ARM: make mach/io.h include optional), PCMCIA was broken. PCMCIA depends on __io() returning a valid i/o address, and most ARM platforms require IO_SPACE_LIMIT be set to 0xffffffff for PCMCIA. This needs a better fix with a fixed i/o address mapping, but for now we just restore things to the previous behavior. This fixes at91, omap1, pxa and sa11xx. pxa needs io.h if PCI is enabled, but PCMCIA is not. sa11xx already has IO_SPACE_LIMIT set to 0xffffffff, so it doesn't need an io.h.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes From Tony Lindgren: Note that this also contains a set of fixes that are not regressions or oopses to properly deal with the smsc911x regulator issue. Basically the regulators must be per board file as the regulators can also come from drivers, such as twl4030. So it's best to dumb down gpmc-smsc911x.c to not even care about the regulators. * 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP: fix section mismatches in usb-host.c ARM: OMAP2+: Fix omap2+ build error ARM: OMAP2+: smsc911x: Add fixed board regulators ARM: OMAP2+: smsc911x: Remove regulator support from gmpc-smsc911x ARM: OMAP2+: smsc911x: Remove unused rate calculation ARM: OMAP2+ smsc911x: Fix possible stale smsc911x flags ARM: OMAP2+: smsc911x: Remove odd gpmc_cfg/board_data redirection ARM: OMAP3+: fix oops triggered in omap_prcm_register_chain_handler(v1) ARM: OMAP2+: OPP: allow OPP enumeration to continue if device is not present arm: omap3: pm34xx.c: Replace printk() with appropriate pr_*() arm: omap3: pm34xx.c: Fix omap3_pm_init() error out paths ARM: OMAP4: Workaround the OCP synchronisation issue with 32K synctimer.

2012-04-05ARM: OMAP2+: hwmod: Fix wrong SYSC_TYPE1_XXX_MASK bit definitionsVaibhav Hiremath
In the SYSC_TYPE1_XXX_MASK configuration, SYSC_XXX_SHIFT macro is used which is not defined anywhere in the kernel. Until now the build was going through successfully, since it is not being used anywhere in kernel. This bug got introduced by the commit 358f0e630d5409ab3837b86db3595560eae773b6 ("OMAP3: hwmod: support to specify the offset position of various SYSCONFIG register bits.")

Some modules doesn't have SYSC_HAS_ENAWAKEUP bit available (ex: usb host uhh module) in absence of this flag omap_hwmod_enable/disable_wakeup avoids configuring pad mux wakeup capability. Configure sysc if SYSC_HAS_ENAWAKEUP is available and for other cases try enabling/disabling wakeup from mux_pad pins.
