f6c8965a 85 licensed by ARM Ltd and targeted at embedded applications and
1da177e4 86 handhelds such as the Compaq IPAQ. ARM-based PCs are no longer
f6c8965a 87 manufactured, but legacy ARM-based PC hardware remains popular in

109 help
110 DMA mapping framework by default aligns all buffers to the smallest
111 PAGE_SIZE order which is greater than or equal to the requested buffer
112 size. This works well for buffers up to a few hundreds kilobytes, but
113 for larger buffers it just a waste of address space. Drivers which has
114 relatively small addressing window (like 64Mib) might run out of
115 virtual space with just a few allocations.
116
117 With this parameter you can specify the maximum PAGE_SIZE order for
118 DMA IOMMU buffers. Larger buffers will be aligned only to this
119 specified order. The order is expressed as a power of two multiplied
120 by the PAGE_SIZE.

143 The Extended Industry Standard Architecture (EISA) bus was
144 developed as an open alternative to the IBM MicroChannel bus.
145
146 The EISA bus provided some of the features of the IBM MicroChannel
147 bus while maintaining backward compatibility with cards made for
148 the older ISA bus. The EISA bus saw limited use between 1988 and
149 1995 when it was made obsolete by the PCI bus.

151 Say Y here if you are building a kernel for an EISA-based machine.

1569 This is a problem, because there's no guarantee the final
1570 destination of the symbol, or any candidate locations for a

1572 kernel does not support fixing up the R_ARM_THM_JUMP11 (102)
1573 relocation in modules at all, and it makes little sense to add
