ChangeSet "adaplas: [PATCH] fbdev: Add __iomem annotations to hgafb" had actually broken it - it not only added a (useless) cast in rowaddr(), it had also added a dereferencing. Since it is video memory and since we do memory transfers on the resulting "address"... IOW, it's even exploitable - not that there had been a lot of HGA boxen out there, but... This restores the intended behaviour. Signed-off-by:

here is a fix to a previous ChangeSet from John; 32-bit emulation of flock(fd, F_GETLK, &lock) currently is broken. The ChangeSet: http://linux.bkbits.net:8080/linux-2.5/cset%404152257aJKu1UClRcfvhsK6IjGYSeQ?nav=index.html|ChangeSet@-12w from John Engel <jhe@us.ibm.com> fixes an off-by-one error and according to the ChangeSet comment, it also contains a fix to handle l_len < 0 which is now defined in POSIX 1003.1-2001 from the fcntl man page. Gordon Jin <gordon.jin@intel.com> reports that the added test causes compat_sys_fcntl[64] to fail: If fcntl(fd, F_GETLK, &lock) finds no conflicting lock it sets l_whence to F_UNLCK, leaves all the other fields unchanged, and returns 0. The (f.l_start < 0) test wrongly converts this to an EINVAL result. The underlying sys_fcntl function which compat_sys_fcntl and compat_sys_fcntl64 invoke already handles POSIX behavior correctly. The additional tests in the compat wrappers are not needed. Here is a test case; its expected result is: PASS get flock: l_type=1, l_whence=0, l_start=145, l_len=10 #include <stdlib.h> #include <unistd.h> #include <fcntl.h> #include <errno.h> #include <stdio.h> int main(int argc, char *argv[]) { int fd; struct flock fl; char buf[255]; fl.l_type = F_WRLCK; fl.l_whence = SEEK_END; fl.l_start = -100; fl.l_len = -10; /* fl.l_whence = SEEK_SET; fl.l_start = 100; fl.l_len = 10; */ switch(fork()) { case -1: perror("fork"); exit(-1); case 0: fd = open("/tmp/testfile", O_RDWR|O_CREAT, 0600); if (fd == -1) { perror("open"); exit(-1); } if (write(fd, buf, 255) == -1) { perror("write"); exit(-1); } if (fcntl(fd, F_SETLK, &fl) == -1) { perror("F_SETLK"); exit(-1); } sleep(2); break; default: sleep(1); fd = open("/tmp/testfile", O_RDWR|O_CREAT, 0600); if (fd == -1) { perror("open"); exit(-1); } if (fcntl(fd, F_SETLK, &fl) != -1 || errno != EAGAIN) { perror("F_SETLK"); exit(1); } fl.l_type = F_WRLCK; /* fl.l_whence = SEEK_SET; fl.l_start = 0; fl.l_len = 0; */ if (fcntl(fd, F_GETLK, &fl) == -1) { perror("F_GETLK"); printf("FAIL\n"); exit(-1); } printf("PASS\n"); printf("get flock: l_type=%d, l_whence=%d, l_start=%zd, " "l_len=%zd\n", fl.l_type, fl.l_whence, (size_t) fl.l_start, (size_t) fl.l_len); break; } exit(0); } Signed-off-by:

* s_4bri.c has a nasty typo - bogus & in qBri_cpu_trapped(). We have void *base; followed by regs[0] = READ_DWORD((&base + offset) + 0x70); which is *NOT* what is meant there - instead of access to memory pointed to by base we get access to _stack_ at some offset from the place where the local variable base lives.

* new helpers - READ_BYTE() and WRITE_BYTE(). On Linux they are needed, since direct access to iomem pointers is not allowed (and does not work on some architectures). * memcpy() to/from iomem is not allowed on Linux (same story). Proper primitives are memcpy_toio() and memcpy_fromio(). Several places misused memcpy(); switched to memcpy_{to,from}io(). Signed-off-by: -

* adds new helpers ({GET,PUT}_{WORD,DWORD}) parallel to READ_WORD et.al., but used on normal memory instead of iomem. Instances of READ_WORD and friends that are applied to vmalloc'ed memory and local variables switched to new helpers. Signed-off-by: -

Patch from Christoph Hellwig These routine in arm is unused (in fact not even compiled). Instead of converting it to local_softirq_pending I'd suggest just removing it as below as it's been there totally unused for a long time.

The special non-signalling NaN flag was escaping and setting some FPSCR exception enable flags. Ensure that this flag is masked out before we update the FPSCR.
