2008-12-02[ARM] pxa/MioA701: discovered new gpio definitions.Robert Jarzmik2-13/+18
The charger enable gpio is straight (1 means draw from USB Vbus, 0 mean do not draw). The USB Vbus sensing is inverted (1 means no Vbus voltage sensed, 0 means Vbus voltage present). Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Eric Miao <eric.miao@marvell.com>
2008-12-02[ARM] pxa/MioA701: change reset function to preserve RTC.Robert Jarzmik1-2/+2
Change the halt and reboot method from gpio based to "jump to ROM IPL beginning". This gives control back to IPL, which without PowerOn key pressed, will put the device into deep sleep until PowerOn is pressed for 1 second. But this has the benefit of keeping the RTC registers across reboots, which is good for OS change.

2008-12-02[ARM] pxa: cpufreq-pxa2xx: sdram_rows detection supportPhilipp Zabel2-3/+27

2008-12-02[ARM] pxa: cpufreq-pxa2xx: allow frequency table selectionMarc Zyngier1-13/+19
Following the removal of the "->policy" usage for PXA255 in patch 459fc208abd1b365fa013c17d433dfb5b4bc1e3a (cpufreq: remove policy->governor setting in drivers initialization), this patch introduces an option (called "pxa255_turbo_table") to select either the "run" or "turbo" frequency table. It also cures the runtime warning that was printed each time the frequency was changed. Got rid of all references to CPUFREQ_POLICY_* for pxa255, and sticked with the run/turbo thing. Tested on an Arcom/Eurotech Viper. Signed-off-by: Marc Zyngier <maz@misterjones.org> Acked-by: Dominik Brodowski <linux@dominikbrodowski.net> Signed-off-by: Eric Miao <eric.miao@marvell.com>

2008-12-02[ARM] pxa: add support for additional GPIOs on PXA26xEric Miao5-16/+95
Original patch from Marek Vasut, the problems with PXA26x are: 1. there are additional 4 GPIOs 86,87,88,89 have their direction bits inverted in GPDR2, as well as their alternate function bits being '1' for their GPIO functionality in GAFRx 2. there is no easy way to decide if the processor is a pxa26x or a pxa250/pxa255 at run-time, so the assumption here is the pxa26x will be treated as one of the pxa25x variants, and board code should have a better knowledge of the processor it is featured Introduce pxa26x_init_irq() for the second purpose, and treat the additional GPIOs > 85 on PXA25x specially. Kconfig option CONFIG_CPU_PXA26x is introduced to optimize the code a bit when PXA26x support isn't needed. Board config options have to select this to enable the support for PXA26x. __gpio_is_inverted() will be optimized way when CONFIG_CPU_PXA26x isn't selected.

2008-12-02Revert "[ARM] pxa: introduce cpu_is_pxa26x()"Eric Miao2-9/+1
This reverts commit da1a3dc0ebb4f9209a1939eaa6b18901e0cd7bc0. The originally proposed way in the above commit is incorrect. And there is no easy way to distinguish between pxa25x and pxa26x at run-time. Signed-off-by: Eric Miao <eric.miao@marvell.com>
2008-12-02[ARM] pxa: use 'pxa_last_gpio' instead of 'gpio_nr' in mfp-pxa2xx.cEric Miao2-10/+6
The 'gpio_nr' can really be inferred by 'pxa_last_gpio', and since we already have that variable, remove the unnecessary 'gpio_nr' now. Also, fix the incorrect GPIO number passed in pxa27x_init_irq(). Note: pxa_last_gpio should be initialized earlier, and this is true since it's been assigned in machine_desc->init_irq().

2008-11-20[IA64] Rationalize kernel mode alignment checkingTony Luck2-1/+2
Itanium processors can handle some misaligned data accesses. They also provide a mode where all such accesses are forced to trap. The kernel was schizophrenic about use of this mode: * Base kernel code ran in permissive mode where the only traps generated were from those cases that the h/w could not handle. * Interrupt, syscall and trap code ran in strict mode where all unaligned accesses caused traps to the 0x5a00 unaligned reference vector. Use strict alignment checking throughout the kernel, but make sure that we continue to let user mode use more relaxed mode as the default. Signed-off-by: Tony Luck <tony.luck@intel.com>
2008-11-20x86: Fix interrupt leak due to migrationMatthew Wilcox1-0/+14
When we migrate an interrupt from one CPU to another, we set the move_in_progress flag and clean up the vectors later once they're not being used. If you're unlucky and call destroy_irq() before the vectors become un-used, the move_in_progress flag is never cleared, which causes the interrupt to become unusable. This was discovered by Jesse Brandeburg for whom it manifested as an MSI-X device refusing to use MSI-X mode when the driver was unloaded and reloaded repeatedly.

But since translate_usr_offset() returns -1 for invalid offsets, addr can now get the value 0xffffffff which then fails the next return-value sanity check and thus the kernel tries to access invalid memory: if (addr < 0) break; Fix this bug by modifying translate_usr_offset() to take and return values of type compat_ulong_t, and by returning the value "sizeof(struct pt_regs)" as an error indicator. Additionally change the sanity check to check for return values for >= sizeof(struct pt_regs). This patch survived my compile and run-tests.
