2010-10-20spi/omap2_mcspi: Verify TX reg is empty after TX only xfer with DMAIlkka Koskinen
In case of TX only with DMA, the driver assumes that the data has been transferred once DMA callback in invoked. However, SPI's shift register may still contain data. Thus, the driver is supposed to verify that the register is empty and the end of the SPI transfer has been reached.

2010-10-20spi/omap2_mcspi: disable channel after TX_ONLY transfer in PIO modeJason Wang
In the TX_ONLY transfer, the SPI controller also receives data simultaneously and saves them in the rx register. After the TX_ONLY transfer, the rx register will hold the random data received during the last tx transaction. If the direct following transfer is RX_ONLY, this random data has the possibility to affect this transfer like this: When the SPI controller is changed from TX_ONLY to RX_ONLY, the random data makes the rx register full immediately and triggers a dummy write automatically(in SPI RX_ONLY transfers, we need a dummy write to trigger the first transaction). So the first data received in the RX_ONLY transfer will be that random data instead of something meaningful. We can avoid this by inserting a Disable/Re-enable toggle of the channel after the TX_ONLY transfer, since it purges the rx register.

2010-10-20arm: remove machine_desc.io_pg_offst and .phys_ioNicolas Pitre
Since we're now using addruart to establish the debug mapping, we can remove the io_pg_offst and phys_io members of struct machine_desc. The various declarations were removed using the following script: grep -rl MACHINE_START arch/arm | xargs \ sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }' [ Initial patch was from Jeremy Kerr, example script from Russell King ] Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org> Acked-by: Eric Miao <eric.miao at canonical.com>
2010-10-20arm: use addruart macro to establish debug mappingsJeremy Kerr
Since we can get both physical and virtual addresses from the addruart macro, we can use this to establish the debug mappings. In the case of CONFIG_DEBUG_ICEDCC, we don't need any mappings, but may still need to setup r7 correctly. Incorporating ASM changes from Nicolas Pitre <npitre@fluxnic.net>.

2010-10-20arm: return both physical and virtual addresses from addruartJeremy Kerr
Rather than checking the MMU status in every instance of addruart, do it once in kernel/debug.S, and change the existing addruart macros to return both physical and virtual addresses. The main debug code can then select the appropriate address to use. This will also allow us to retreive the address of a uart for the MMU state that we're not current in.

2010-10-20apic, x86: Use BIOS settings for IBS and MCE threshold interrupt LVT offsetsRobert Richter
We want the BIOS to setup the EILVT APIC registers. The offsets were hardcoded and BIOS settings were overwritten by the OS. Now, the subsystems for MCE threshold and IBS determine the LVT offset from the registers the BIOS has setup. If the BIOS setup is buggy on a family 10h system, a workaround enables IBS. If the OS determines an invalid register setup, a "[Firmware Bug]: " error message is reported. We need this change also for upcomming cpu families.

2010-10-20apic, x86: Check if EILVT APIC registers are available (AMD only)Robert Richter
This patch implements checks for the availability of LVT entries (APIC500-530) and reserves it if used. The check becomes necessary since we want to let the BIOS provide the LVT offsets. The offsets should be determined by the subsystems using it like those for MCE threshold or IBS. On K8 only offset 0 (APIC500) and MCE interrupts are supported. Beginning with family 10h at least 4 offsets are available. Since offsets must be consistent for all cores, we keep track of the LVT offsets in software and reserve the offset for the same vector also to be used on other cores. An offset is freed by setting the entry to APIC_EILVT_MASKED. If the BIOS is right, there should be no conflicts. Otherwise a "[Firmware Bug]: ..." error message is generated. However, if software does not properly determines the offsets, it is not necessarily a BIOS bug.

There may be wakeup sources that aren't associated with any devices and their statistics information won't be available from sysfs.

2010-10-19x86, mm: Hold mm->page_table_lock while doing vmalloc_syncJeremy Fitzhardinge
Take mm->page_table_lock while syncing the vmalloc region. This prevents a race with the Xen pagetable pin/unpin code, which expects that the page_table_lock is already held. If this race occurs, then Xen can see an inconsistent page type (a page can either be read/write or a pagetable page, and pin/unpin converts it between them), which will cause either the pin or the set_p[gm]d to fail; either will crash the kernel. vmalloc_sync_all() should be called rarely, so this extra use of page_table_lock should not interfere with its normal users. The mm pointer is stashed in the pgd page's index field, as that won't be otherwise used for pgds.
