* mm, x86: Remove debug_pagealloc_enabledStanislaw Gruszka2011-12-061-6/+0
| | | | | | | | | | | | | | | | | | | When (no)bootmem finish operation, it pass pages to buddy allocator. Since debug_pagealloc_enabled is not set, we will do not protect pages, what is not what we want with CONFIG_DEBUG_PAGEALLOC=y. To fix remove debug_pagealloc_enabled. That variable was introduced by commit 12d6f21e "x86: do not PSE on CONFIG_DEBUG_PAGEALLOC=y" to get more CPA (change page attribude) code testing. But currently we have CONFIG_CPA_DEBUG, which test CPA.

* arch/x86/kernel/e820.c: quiet sparse noise about plain integer as NULL pointerH Hartley Sweeten2011-12-051-1/+1
| | | | | | | | | | | | | The last parameter to sort() is a pointer to the function used to swap items. This parameter should be NULL, not 0, when not used.

* arch/x86/kernel/e820.c: Eliminate bubble sort from sanitize_e820_map()Mike Ditto2011-12-051-35/+24
| | | | | | | | | | | | | | | | | | Replace the bubble sort in sanitize_e820_map() with a call to the generic kernel sort function to avoid pathological performance with large maps. On large (thousands of entries) E820 maps, the previous code took minutes to run; with this change it's now milliseconds.

* x86: Fix mmap random address rangeLudwig Nussel2011-12-051-2/+2
| | | | | | | | | | | | | | | | | | | On x86_32 casting the unsigned int result of get_random_int() to long may result in a negative value. On x86_32 the range of mmap_rnd() therefore was -255 to 255. The 32bit mode on x86_64 used 0 to 255 as intended. The bug was introduced by 675a081 ("x86: unify mmap_{32|64}.c") in January 2008.

Currently, I/O wakeup is marked as present for all OMAP3 SoCs other than the AM3505/3517. The TI81xx family of SoCs are at present considered to be OMAP3 SoCs, but don't support I/O wakeup. To resolve this, convert the existing blacklist approach to an explicit, whitelist support, in which only SoCs which are known to support I/O wakeup are listed. (At present, this only includes OMAP34xx, OMAP3503, OMAP3515, OMAP3525, OMAP3530, and OMAP36xx.) Also, the current code incorrectly detects the presence of a software-controllable I/O chain clock on several chips that don't support it. This results in writes to reserved bitfields, unnecessary delays, and console messages on kernels running on those chips: http://www.spinics.net/lists/linux-omap/msg58735.html Convert this test to a feature test with a chip-by-chip whitelist.

ABE_FCLK --> AESS_FCLK --> OCP_ABE_ICLK The AESS_FCLK and OCP_ABE_ICLK clocks both have dividers which determine their operational frequency. However, the dividers for the AESS_FCLK and OCP_ABE_ICLK are controlled via a single bit, which is the CM1_ABE_AESS_CLKCTRL[24] bit. When this bit is set to 0, the AESS_FCLK divider is 1 and the OCP_ABE_ICLK divider is 2. Similarly, when this bit is set to 1, the AESS_FCLK divider is 2 and the OCP_ABE_ICLK is 1. The above relationship between the AESS_FCLK and OCP_ABE_ICLK dividers ensure that the OCP_ABE_ICLK clock is always half the frequency of the ABE_CLK... OCP_ABE_ICLK = ABE_FCLK/2 The divider for the OCP_ABE_ICLK is currently missing so add a divider that will ensure the OCP_ABE_ICLK frequency is always half the ABE_FCLK frequency.

It may be necessary for some DPLLs to use a different function and so use the DPLLs recalc() function pointer instead. An example is the DPLL_ABE on OMAP4 which can have a 4X multiplier in addition to the usual MN multipler and dividers and therefore uses a different round_rate and recalc function.

This avoids issues where the DPLL frequency is slightly different than what debugfs clock tree reports using the old target rate. An example of a clock that requires this is DPLL_ABE on OMAP4 which can have a 4x multiplier on top of the usual MN dividers depending on register settings. This requires a special round_rate function that might yield a rate different from the initial target.

An example of a clock that requires this is DPLL_ABE on OMAP4 which can have a 4x multiplier on top of the usual MN dividers depending on register settings. This requires a special round_rate function that might yield a rate different from the initial target.

This is achieved by setting CM_CLKMODE_DPLL_ABE.DPLL_REGM4XEN bit in CKGEN module of CM1. From the OMAP4 TRM: Fdpll = Fref x 2 x (4 x M/(N+1)) in case REGM4XEN bit field is set (only applicable to DPLL_ABE). Add new round_rate() and recalc() functions for OMAP4, that check the setting of REGM4XEN bit and handle this appropriately. The new functions are a simple wrapper on top of the existing omap2_dpll_round_rate() and omap2_dpll_get_rate() functions to handle the REGM4XEN bit. The REGM4XEN bit is only implemented for the ABE DPLL on OMAP4 and so only dpll_abe_ck uses omap4_dpll_regm4xen_round_rate() and omap4_dpll_regm4xen_recalc() functions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These files didn't exist at the time of the module.h split, and so were not fixed by the commits on that baseline. Since they use the EXPORT_SYMBOL and/or THIS_MODULE macros, they will need the new export.h file included that provides them.
