| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously the code only acquired spinlock after increasing / decreasing the usecount value, which is wrong. This leaves a small window where a task switch may occur between the check of the usecount and the actual wakeup / sleep of the domain. Fixed by moving the spinlock locking before the usecount access. Left the usecount as atomic_t if someone wants an easy access to the parameter through atomic_read.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 7d7e1eba (ARM: OMAP2+: Prepare for irqs.h removal) changed the interrupts to allow enabling sparse IRQ, but accidentally added the omap3 INTC base to the local IRQ. This causes the following: twd: can't register interrupt 45 (-22) twd_local_timer_register failed -22 The right fix is to not add any base, as it is a local timer. For the OMAP44XX_IRQ_LOCALWDT we had defined earlier there are no users, so no need to fix that.

But it's not true. These pins are shared by usdhc3 and gpmi-nand. We should have the pins functional for gpmi-nand when usdhc3 is disabled. Move the pins out of 'hog', so that pins only work in gpio mode as CD and WP when usdhc3 is enabled, and otherwise they are available for gpmi-nand.

| * | MIPS: perf: Add perf functionality for BMIPS5000Al Cooper2012-10-111-1/+102
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add hardware performance counter support to kernel "perf" code for BMIPS5000. The BMIPS5000 performance counters are similar to MIPS MTI cores, so the changes were mostly made in perf_event_mipsxx.c which is typically for MTI cores.

| * | MIPS: perf: Remove unnecessary #ifdefAl Cooper2012-10-111-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The #ifdef for CONFIG_HW_PERF_EVENTS is not needed because the Makefile will only compile the module if this config option is set. This means that the code under #else would never be compiled. This may have been done to leave the original broken code around for reference, but the FIXME comment above the code already shows the broken code.

| * | MIPS: perf: Add cpu feature bit for PCI (performance counter interrupt)Al Cooper2012-10-115-3/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PCI (Program Counter Interrupt) bit in the "cause" register is mandatory for MIPS32R2 cores, but has also been added to some R1 cores (BMIPS5000). This change adds a cpu feature bit to make it easier to check for and use this feature.

| * | MIPS: perf: Change the "mips_perf_event" table unsupported indicator.Al Cooper2012-10-111-150/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change the indicator from 0xffffffff in the "event_id" member to zero in the "cntr_mask" member. This removes the need to initialize entries that are unsupported. This also solves a problem where the number of entries in the table was increased based on a globel enum used for all platforms, but the new unsupported entries were not added for mips. This was leaving new table entries of all zeros that we not marked UNSUPPORTED.

| * | MIPS: Align swapper_pg_dir to 64K for better TLB Refill code.David Daney2012-10-112-10/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We can save an instruction in the TLB Refill path for kernel mappings by aligning swapper_pg_dir on a 64K boundary. The address of swapper_pg_dir can be generated with a single LUI instead of LUI/{D}ADDUI. The alignment of __init_end is bumped up to 64K so there are no holes between it and swapper_pg_dir, which is placed at the very beginning of .bss. The alignment of invalid_pmd_table and invalid_pte_table can be relaxed to PAGE_SIZE. We do this by using __page_aligned_bss, which has the added benefit of eliminating alignment holes in .bss.
