2009-10-26x86-64: Fix register leak in 32-bit syscall audtingJan Beulich
Restoring %ebp after the call to audit_syscall_exit() is not only unnecessary (because the register didn't get clobbered), but in the sysenter case wasn't even doing the right thing: It loaded %ebp from a location below the top of stack (RBP < ARGOFFSET), i.e. arbitrary kernel data got passed back to user mode in the register.

2009-10-26x86: crash_dump: Fix non-pae kdump kernel memory accessesJiri Slaby
Non-PAE 32-bit dump kernels may wrap an address around 4G and poke unwanted space. ptes there are 32-bit long, and since pfn << PAGE_SIZE may exceed this limit, high pfn bits are cropped and wrong address mapped by kmap_atomic_pfn in copy_oldmem_page. Don't allow this behavior in non-PAE kdump kernels by checking pfns passed into copy_oldmem_page. In the case of failure, userspace process gets EFAULT.

2009-10-26x86: Side-step lguest problem by only building cmpxchg8b_emu for pre-PentiumRusty Russell
Commit 79e1dd05d1a22 "x86: Provide an alternative() based cmpxchg64()" broke lguest, even on systems which have cmpxchg8b support. The emulation code gets used until alternatives get run, but it contains native instructions, not their paravirt alternatives. The simplest fix is to turn this code off except for 386 and 486 builds.

2009-10-26sh: Check for return_to_handler when unwinding the stackMatt Fleming
When CONFIG_FUNCTION_GRAPH_TRACER is enabled the function graph tracer may patch return addresses on the stack with the address of return_to_handler(). This really confuses the DWARF unwinder because it will try find the caller of return_to_handler(), not the caller of the real return address. So teach the DWARF unwinder how to find the real return address whenever it encounters return_to_handler(). This patch does not cope very well when multiple return addresses on the stack have been patched. To make it work properly it would require state to track how many return_to_handler()'s have been seen so that we'd know where to look in current->curr_ret_stack[]. So for now, instead of trying to handle this, just moan if more than one return address on the stack has been patched.

2009-10-25ARM: Use GFP_DMA only for masks _less_ than 32-bitRussell King

2009-10-25ARM: Fix signal restart issues with NX and OABI compatRussell King
The signal restarting code was placed on the user stack when OABI compatibility is enabled. Unfortunately, with an EABI NX executable, this results in an attempt to run code from the non-executable stack, which segfaults the application. Fix this by placing the code in the vectors page, along side the signal return code, and directing the application to that code.

2009-10-22omap3: PM: enable UART3 module wakeupsKevin Hilman
UART3 is in the PER powerdomain. If PER goes idle/inactive independently of CORE, for UART3 to wakeup it must have its wakeup enable bits setup in PM_WKEN_PER. This patch enables these bits. The reason it works when PER and CORE work together is because when CORE goes inactive/retention, the IOPAD wakeups are enabled and trigger UART3 wakeup. Without this patch, when the UART inactivity timer fires for UART3, its clocks are disabled and it's unable to wakeup so will be unusable until PER is awoken by another source. Another way of testing is by keeping CORE on during suspend but allowing PER to hit retention # echo 3 > /debug/pm_debug/core_pwrdm/suspend then enter suspend # echo mem > /sys/power/state Without this patch, UART3 will be unable to wakeup the system.

2009-10-22omap1: Fix DSP public peripherals support for ams-deltaJanusz Krzysztofik
DSP public peripherals used to work on OMAP1510 based (or all OMAP1 class?) machines as long as old dspgateway code were present in the l-o tree. For several months it is no longer included, breaking support for McBSP1 based audio on Amstrad Delta, for example. This patch, derived from the old dspgateway code, corrects the problem for the board by simply taking the DSP out of reset state, I guess. That way, things should not break when a new dsp code is added to the tree, and the change can be reverted then. If there are any reports on McBSP1 or other DSP public peripherals not working for other OMAP1 machines (I've not heard of any for now), I can prepare a more general patch providing an extra include file with a helper function defined.

2009-10-22omap1: Fix redundant UARTs pin muxing that can break other hardware supportJanusz Krzysztofik
Commit 15ac408ee5a509053a765b816e9179515329369f removed enabled_uart and OMAP_TAG_UART. This works for mach-omap2, but causes issues on mach-omap1 for some boards as the mach-omap1 serial.c was muxing pins based on the enabled_uart flag for 15xx. Fix this by muxing pins in board-*.c files for the 15xx boards for the uart ports that had enabled_uart flag set before the commit above. Tested on Amsdtrad Delta only. Note that in the future we should add support for powering down the uarts with a timer like mach-omap2/serial.c does. Otherwise the enabled uarts will be blocking retention-while-idle.
