[parisc-linux] uaccess.h BUG (non-feature?)

[jsoe0708@tiscali.be]

Hi all,

In the tools evms-1.2 I finaly found the solution in itself :-?

Here is the code:
...
#if LINUX_VERSION_CODE >= KERNEL_VERSION(2,4,18)
                rc = evms_cs_kernel_ioctl(new_disk, BLKGETSIZE64,
                                          (ulong) & new_disk->total_vsectors);
                if (!rc) {
                        /* convert bytes to 512 byte sectors */  
                        new_disk->total_vsectors >>= EVMS_VSECTOR_SIZE_SHIFT;
                } else
#endif
...

which seems to be kind to verify that kernel support this feature, isn't
it?

But hppa kernel put_kernel(x,ptr) did not send error return code in that
case of test (just printk bug message).

I do not know if it is the best patch but here is the simple solution I test:
...
#if BITS_PER_LONG == 32
#define LDD_KERNEL(ptr)         BUG(); __gu_err=-1;
#define LDD_USER(ptr)           BUG(); __gu_err=-1;
#define STD_KERNEL(x, ptr)      BUG(); __pu_err=-1;
#define STD_USER(x, ptr)        BUG(); __pu_err=-1;
#else
...

Seems to work even with annoying bug messages.

Thanks in advance for advise,
    Joel
