2012-12-15Revert "x86-64/efi: Use EFI to deal with platform wall clock (again)"Linus Torvalds
This reverts commit bd52276fa1d4 ("x86-64/efi: Use EFI to deal with platform wall clock (again)"), and the two supporting commits: da5a108d05b4: "x86/kernel: remove tboot 1:1 page table creation code" 185034e72d59: "x86, efi: 1:1 pagetable mapping for virtual EFI calls") as they all depend semantically on commit 53b87cf088e2 ("x86, mm: Include the entire kernel memory map in trampoline_pgd") that got reverted earlier due to the problems it caused. This was pointed out by Yinghai Lu, and verified by me on my Macbook Air that uses EFI. Pointed-out-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2012-12-15Revert "x86, mm: Include the entire kernel memory map in trampoline_pgd"Linus Torvalds
This reverts commit 53b87cf088e2ea68d7c59619d0214cc15bb76133. It causes odd bootup problems on x86-64. Markus Trippelsdorf gets a repeatable oops, and I see a non-repeatable oops (or constant stream of messages that scroll off too quickly to read) that seems to go away with this commit reverted. So we don't know exactly what is wrong with the commit, but it's definitely problematic, and worth reverting sooner rather than later.

2012-12-15ARM: OMAP4: Fix EMU clock domain always onJon Hunter
Commit d043d87 (ARM: OMAP2+: clockdomain: bypass clockdomain handling when disabling unused clks) skips the decrementing of a clock-domains use count if the clocks use count is zero. However, for OMAP4 devices this is causing the EMU clock-domain to be stuck ON as the use count is not getting decremented correctly. The scenario that leads to this problem is described below ... omap_hwmod_setup_all --> _setup --> clkdm_hwmod_enable --> EMU clock domain usecount = 1 --> _enable_clocks --> clk_enable --> trace_clk_div_div usecount = 1 --> clkdm_hwmod_enable --> EMU clock domain usecount = 2 --> _idle --> _disable_clocks --> clk_disable --> trace_clk_div_div usecount = 0 --> clkdm_hwmod_disable --> skips decrement of EMU clock domain usecount because trace_clk_div_div is 0! --> EMU clock domain usecount = 2 --> clkdm_hwmod_disable --> EMU clock domain usecount = 1 Hence, due to the order that a clocks use count is decremented and the clock domain is disabled, it is possible that the clock domain can have a non-zero use count when the actual clock has a use count of 0. Therefore, we should only bypass the clock-domain handling when both the clock-domain and clock in the clock-domain have a use count of 0 and warn when the clock-domain has a zero use count and the clock has a non-zero use count.

2012-12-15ARM: OMAP4460: Workaround ABE DPLL failing to turn-onJon Hunter
With the latest mainline u-boot bootloader (v2012.10), timers (5-8) in the ABE power domain are failing to turn-on. The timers never come out of the disabled state when setting the module-mode field to enable. The problem was exposed when u-boot was updated to NOT configure and lock the ABE DPLL on start-up. If the ABE DPLL is configured and locked by u-boot the problem does not occur. However, if the ABE DPLL is in the idle low-power bypass state and we attempt to enable a timer in the ABE power domain, it remains stuck in the disabled state. It appears to be a problem the timer interface clock as this comes from the ABE DPLL. If we place the ABE DPLL in the MN-bypass state and not the idle low-power state, then this problem is not seen. This problem only appears to occur on OMAP4460 and not OMAP4430. Workaround this problem by locking the ABE DPLL for OMAP4460 in the kernel on boot. By locking the ABE DPLL, when clocks from the ABE DPLL are not being requested the DPLL will transition into a low-power stop mode.

2012-12-15ARM: OMAP4: Enhance support for DPLLs with 4X multiplierJon Hunter
On OMAP4 devices, the ABE DPLL has an internal 4X multiplier that can be enabled or disabled in addition to the standard configurable multiplier (M) for OMAP DPLLs. When configuring the ABE DPLL the 4X multiplier is accounted for by checking to see whether it is enabled or not. However, when calculating a new rate we only check to see if the rate can be achieved with the current setting for the 4X multiplier. Enhance the round_rate() function for such DPLLs to see if the rate can be achieved with the 4X multiplier if it cannot be achieved without the 4X multiplier. This change is necessary, because when using the 32kHz clock as the source clock for the ABE DPLL, the default DPLL frequency for the ABE DPLL cannot be achieved without enabling the 4X multiplier. When using the 32kHz clock as the source clock for the ABE DPLL and attempting to lock the DPLL to 98.304MHz (default frequency), it was found that the DPLL would fail to lock if the low-power mode for the DPLL was not enabled. From reviewing boot-loader settings that configure the ABE DPLL it was found that the low-power mode is enabled when using the 32kHz clock source, however, the documentation for OMAP does not state that this is a requirement. Therefore, introduce a new function for OMAP4 devices to see if low-power mode can be enabled when calculating a new rate to ensure the DPLL will lock. New variables for the last calculated 4X multiplier and low-power setting have been added to the dpll data structure as well as variables defining the bit mask for enabling these features via the DPLL's control_reg. It is possible that we could eliminate these bit masks from the dpll data structure as these bit masks are not unique to OMAP4, if it is preferred. The function omap3_noncore_program_dpll() has been updated to avoid passing the calculated values for the multiplier (M) and divider (N) as these are stored in the clk structure.

2012-12-15ARM: OMAP4: Add function table for non-M4X dpllsJon Hunter
Currently all OMAP4 non-core DPLLs use the same function table for configuring DPLLs. For these DPLLs, the function omap4_dpll_regm4xen_recalc() is used to recalculate the DPLL rate and the function omap4_dpll_regm4xen_round_rate() is used to calculate the closest rate to that requested. However, these omap4_dpll_regm4xen_xxx() functions are only applicable to the ABE DPLL and not the other non-core DPLLs. Therefore, add a new function table for non-core DPLLs that do not include the 4X-multiplier (M4X). Please note that using these omap4_dpll_regm4x_xxx() function works for the non-M4X DPLLs today because we only check to see if the 4X multiplier is enabled when calculating the rate. However, it is planned that the dpll functions will be enhanced to enable the 4X multiplier as necessary (in order to achieve the requested rate) and so calling these functions for non-M4X dplls will no longer work.

2012-12-15ARM: OMAP4: Update timer clock aliasesJon Hunter
Commit "ARM: dts: OMAP4: Update timer addresses" updated the device-tree names of the OMAP4 timers 5-7 because the default address for the timers was changed from the L3 address to the MPU private address. When booting with device-tree, this introduces a regression when attempting to set the parent clock of timers 5-7 to the sys_clk_div_ck. Therefore, update the clock aliases for timer 5-7 to reflect the updated device-tree name for the timers.

2012-12-14OMAP: board-files: fix i2c_bus for tfp410Tomi Valkeinen
The i2c handling in tfp410 driver, which handles converting parallel RGB to DVI, was changed in 958f2717b84e88bf833d996997fda8f73276f2af (OMAPDSS: TFP410: pdata rewrite). The patch changed what value the driver considers as invalid/undefined. Before the patch, 0 was the invalid value, but as 0 is a valid bus number, the patch changed this to -1. However, the fact was missed that many board files do not define the bus number at all, thus it's left to 0. This causes the driver to fail to get the i2c bus, exiting from the driver's probe with an error, meaning that the DVI output does not work for those boards. This patch fixes the issue by changing the i2c_bus number field in the driver's platform data from u16 to int, and setting the bus number to -1 in the board files for the boards that did not define the bus. The exception is devkit8000, for which the bus is set to 1, which is the correct bus for that board. The bug exists in v3.5+ kernels.

In commit d0a21265dfb5fa8a David Rientjes unified various archs' module_alloc implementation (including x86) and removed the graduitous shortcut for size == 0. Then, in commit de7d2b567d040e3b, Joe Perches added a warning for zero-length vmallocs, which can happen without kallsyms on modules with no init sections (eg. zlib_deflate). Fix this once and for all; the module code has to handle zero length anyway, so get it right at the caller and remove the now-gratuitous checks within the arch-specific module_alloc implementations.

2012-12-14module: add syscall to load module from fdKees Cook
As part of the effort to create a stronger boundary between root and kernel, Chrome OS wants to be able to enforce that kernel modules are being loaded only from our read-only crypto-hash verified (dm_verity) root filesystem. Since the init_module syscall hands the kernel a module as a memory blob, no reasoning about the origin of the blob can be made. Earlier proposals for appending signatures to kernel modules would not be useful in Chrome OS, since it would involve adding an additional set of keys to our kernel and builds for no good reason: we already trust the contents of our root filesystem. We don't need to verify those kernel modules a second time. Having to do signature checking on module loading would slow us down and be redundant. All we need to know is where a module is coming from so we can say yes/no to loading it. If a file descriptor is used as the source of a kernel module, many more things can be reasoned about. In Chrome OS's case, we could enforce that the module lives on the filesystem we expect it to live on. In the case of IMA (or other LSMs), it would be possible, for example, to examine extended attributes that may contain signatures over the contents of the module. This introduces a new syscall (on x86), similar to init_module, that has only two arguments. The first argument is used as a file descriptor to the module and the second argument is a pointer to the NULL terminated string of module arguments.
