* ARM: make_coherent: avoid recalculating the pfn for the modified pageRussell King2010-01-201-6/+6
| | | | | | | We already know the pfn for the page to be modified in make_coherent, so let's stop recalculating it unnecessarily. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* ARM: make_coherent: fix problems with highpte, part 1Russell King2010-01-201-2/+11
| | | | | | | | | | | | | | | update_mmu_cache() is called with a page table already mapped. We call make_coherent(), which then calls adjust_pte() which wants to map other page tables. This causes kmap_atomic() to BUG() because the slot its trying to use is already taken. Since do_adjust_pte() modifies the page tables, we are also missing any form of locking, so we're risking corrupting the page tables. Fix this by using pte_offset_map_nested(), and taking the pte page table lock around do_adjust_pte(). Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* | x86, apic: use logical flat for systems with <= 8 logical cpusSuresh Siddha2010-01-182-19/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We can use logical flat mode if there are <= 8 logical cpu's (irrespective of physical apic id values). This will enable simplified and efficient IPI and device interrupt routing on such platforms. This has been tested to work on both Intel and AMD platforms. Exceptions like IBM summit platform which can't use logical flat mode are addressed by using OEM platform checks.

* | x86, apic: use physical mode for IBM summit platformsSuresh Siddha2010-01-181-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Chris McDermott from IBM confirmed that hurricane chipset in IBM summit platforms doesn't support logical flat mode. Irrespective of the other things like apic_id's, total number of logical cpu's, Linux kernel should default to physical mode for this system. The 32-bit kernel does so using the OEM checks for the IBM summit platform. Add a similar OEM platform check for the 64bit kernel too. Otherwise the linux kernel boot can hang on this platform under certain bios/platform settings.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sony VAIO VGN-P11G with ALC262 codec has only one input pin, and the recording doesn't work with model=auto because ALC262 parser sets the wrong cap NIDs to choose the route and the default route for the sole input pin wasn't initialized properly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On my laptop (HP dv6-1110ax), there are no OEM strings in SMBIOS of type "HP_Mute_LED*". Hence, the GPIO for the mute button LED doesn't get set properly. I didn't find the strings in my cousin's laptop (HP dv9500t CTO) either. As per the documentation of find_mute_led_gpio(), these strings occur in HP B-series systems - so, before scanning the SMBIOS strings, we need to check if we're dealing with a B-series system. Need to get confirmation from HP if this logic takes care of all the systems. I'm trying to poke a friend there.

E.g. fetching them twice may return 2 different values after writable limits are implemented. I.e. either use rlimit helpers added in 3e10e716abf3c71bdb5d86b8f507f9e72236c9cd or ACCESS_ONCE if not applicable.

| * | | | | powerpc: cpumask_of_node() should handle -1 as a nodeAnton Blanchard2010-01-151-1/+3

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 57b150cce8e004ddd36330490a68bfb59b7271e9 (irq: only update affinity if ->set_affinity() is sucessfull) broke xics irq affinity. We need to use the cpumask passed in, instead of accessing ->affinity directly. Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It seems there is a thinko in the TLB invalidation code that makes the tlbie in the loop executed just once. The intended check was probably 'gt', not 'lt'. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various kernel asm modifies SRR0/SRR1 just before executing a rfi. If such code crosses a page boundary you risk a TLB miss which will clobber SRR0/SRR1. Avoid this by always pinning kernel instruction TLB space.
