xvmalloc will not currently function with 64K pages. Newly allocated pages will be inserted at an offset beyond the end of the first-level index. This tuning is needed to properly size the allocator for 64K pages. The default 3 byte shift results in a second level list size which can not be indexed using the 64 bits of the flbitmap in the xv_pool structure. The shift must increase to 4 bytes between second level list entries to fit the size of the first level bitmap. Here are a few statistics for structure sizes on 32- and 64-bit CPUs with 4KB and 64KB page sizes. bits_per_long 32 64 64 page_size 4,096 4,096 65,535 xv_align 4 8 8 fl_delta 3 3 4 num_free_lists 508 508 4,094 xv_pool size 4,144b 8,216b 66,040b per object overhead 32 64 64 zram struct 0.5GB disk 512KB 1024KB 64KB This patch maintains the current tunings for 4K pages, adds an optimal sizing for 64K pages and adds a safe tuning for any other page sizes.

This patch allows to build both drivers. Previous patch for this failed using -j option. This has been fixed by adding files with include statement for the fullmac driver. Verified this is working using -j4 option. Signed-off-by:

Since 2.6.38-rc1 we are getting a compiler warning due to changed API in net/cfg80211.h. This change fixes the warning but driver will need to be modified later to handle the additional parameters.

Resubmitted the patch to align with staging-next tree. This change depends on suspend/resume patch as sent on Wed, Jan 12, 2011. Only hardware switch state needs to be handled by driver. RFKILL is informed when hardware switch is activated. MAC80211 rfkill_poll callback is used to check hardware switch deactivation. Reviewed-by:

bcm driver copies a buffer length provided by userpace without checking it. RxCntrlMsgBitMask is of type unsigned long so only makes sense to copy sizeof(unsigned long) bytes. Also, copy_from_user() returns the number of bytes that could not be copied. The driver is returning that value as error code instead of -EFAULT. This patch solves both issues. Signed-off-by:
