staging: rdma: hfi1: chip: Remove wrapper function
Drop wrapper function remap_receive_available_interrupt() that wraps a
call to remap_intr() with the only difference being the addition of
macro IS_RCVAVAIL_START to the second argument of remap_intr().
Both the function names give the same information so the wrapper
function can be dropped.
Drop wrapper functions sdma_start_err_halt_wait() and
sdma_start_sw_clean_up() that can be replaced by a direct call to
schedule_work() and tasklet_hi_schedule() respectively both of which
are standard kernel functions.
staging: rdma: hfi1: Remove hfi1_nomsix() wrapper function
This patch removes hfi1_nomsix() wrapper function that is used to wrap
pci_disable_msix() and so substituted the wrapper function by a direct
call to pci_disable_msix().
This patch solves two problems.
The function rtl8192_CalculateBitShift() had an unnecessary variable i
that could be removed by using a single line of code.
After this change, rtl8192_CalculateBitShift() becomes a wrapper
function, so the rtl8192_CalculateBitShift() function has been removed
completely to replace it with a single line of code.

The PCI-1720 is a simple 4 channel analog output board. It also uses a
unique register map.
Separate out the PCI-1720 support as a new driver, adv_pci1720, to ease
maintainability.
Fix some issues with the PCI-1720 support in the new driver:
1) the registers are all 8-bit
2) remove the analog output "reset" when the driver attaches/detaches
3) disable "synchronized output" to simplify the analog outputs
4) remove the need for the private data
5) add support for the BoardID register to allow multiple cards

ARC: [arcompact] Handle bus error from userspace as Interrupt not exception
Bus errors from userspace on ARCompact based cores are handled by core
as a high priority L2 interrupt but current code treated it as interrupt
Handling an interrupt like exception is certainly not going to go unnoticed.
(and it worked so far as we never saw a Bus error from userspace until
IPPK guys tested a DDR controller with ECC error detection etc hence
needed to explicitly trigger/handle such errors)
- So move mem_service exception handler from common code into ARCv2 code.
- In ARCompact code, define mem_service as L2 interrupt handler which
just drops down to pure kernel mode and goes of to enqueue SIGBUS
